My problems with the Constructed Theory of Emotions

I finally finished reading a book.

It took me three years to read.

Three.

Years.

And it’s not because I’m a slow reader. I plowed through Brandon Sanderson’s 1100-page brick The Way of Kings in less than a day. So why, then, did this particular book take me so long?

Well, before I tell you, let me frame the context.

It’s a book that’s getting a lot of traction amongst animal trainers lately, specifically amongst the behaviour analytic crowd.

The book is called How Emotions Are Made, and it’s by Lisa Feldman Barrett, a professor of Psychology and a neuroscientist. In the book she makes a big, and in many peoples’ eyes, compelling, case of emotions being constructed rather than innate.
So, many behaviour analysts love the book, and I feel like a complete dissenter in that crowd, because while they’re all nodding in agreement, I shake my head thinking that some of the main conclusions in the book are seriously flawed.

Swimming against the behaviour analytical crowd

We’ll get to my objections in a minute, but let’s start with: what is the central idea behind the Constructed Theory of Emotions?

What the Constructed Theory of Emotions (CToE) is all about.

The case Barrett makes is that rather than being innate, emotions are constructed.

According to the CToE, emotions are not our reactions to the world, they are our constructions of the world. The theory suggests that our past experiences guide us in making sense of incoming stimuli, and emotions would then be actively constructed from sensory input, previous learning, and language.

In the book, Barrett goes on a quest looking for what she refers to as “fingerprints of emotions”; looking for evidence that humans would have innate facial expressions indicating different emotional states, or that these different emotional states would be processed in specific parts of the brain; in a “fear center” or an “anger center”, for instance.

Her conclusion is that we do not have innate facial expressions related to emotions, but rather, we learned for instance to smile when happy by watching others do it, and she also rejects the notion that categories of emotion such as sadness, fear or anger would take place in a distinct brain location, or brain blobs, as she jokingly calls it, but rather she leans on a body of research that proposes that each instance of emotion is a whole-brain state; emotional processing taking place throughout the whole brain at once.

She rejects the “classic” view of emotions being innate.

“Human beings are not at the mercy of mythical emotion circuits buried deep within animalistic parts of our highly evolved brain: we are architects of our own experience”.(p 40)

Human infants don’t feel emotions, according to Barrett, because they lack the rich set of concepts required to construct them. They do feel affect, though: pleasant or unpleasant sensations, but not fear, sadness or joy.

Barrett also suggests that if someone doesn’t have a concept to describe an emotion, they won’t be able to perceive it. They might still feel the bodily sensations associated with the experience, but won’t be able to label them precisely.

In other words, according to the CToE, the range of emotions a person can experience is limited by their emotional granularity – the ability to construct and identify more precise emotional experiences. And language is crucial here – without language, there would be simply pleasant or unpleasant feelings (affect), and specific emotions concept are not constructed until we start labelling them, using language. According to Barrett, a person with low emotional granularity may experience a stomachache in a particular situation, in contrast to a person with a more granular emotional vocabulary, who might experience anger in the same context.

That is, animals don’t experience emotions, according to the CToE: they simply feel affect. Since they lack language, they can’t categorize emotions, and they go through the world experiencing pleasant and unpleasant situations, and reacting with different degrees of arousal – but not emotions as such. No fear, anger, sadness, joy.

The reason why we think animals feel emotions, according to the CToE, is because we feel emotions, and we anthropomorphize and project. To paraphrase Lisa Feldman Barrett, humans might perceive a dog crouching with ears back and lip licking as fearful, when in fact all he’s feeling is an unpleasant experience, not “fear”.

Barrett suggests that we think animals have emotions because we make the mental inference fallacy: we unknowingly apply our own emotion concepts to the behaviours we observe in the animal, and we wrongly attribute emotions to those behaviours.

“Construction views of emotion are frequently misinterpreted as saying “dogs don’t have emotions”[…] Such simplistic statements are meaningless because they assume emotions have essences so that they can exist, or not, independent of any perceiver. But emotions are perceptions, and every perception requires a perceiver. And therefore every question about an instance of emotion must be asked from a particular point of view.” (p 272)

So, in Barrett’s view, emotions are the concepts we make up when we think about how we feel in situations characterized by some type of affect – but those affects themselves are just somewhere on the scale from pleasant to unpleasant, or characterized by a certain degree of arousal. There’s no such “thing” as fear, rage or happiness, neither for humans, nor for animals.

This, in short, is my understanding of the central themes of the book and the conclusions relevant for those of us interested in animal behaviour and welfare.

And I have major problems with these conclusions. In fact, when first reading the book, I finished chapter 1 and thought “this is clearly wrong”, and so I put the book aside, waiting for someone to debunk it – so that I wouldn’t have to.

And then I waited a couple of years, but I never came across any such critique – and yet I see parts of the world of animal training accepting the teachings of the CToE as absolute and irrefutable; I’ve even attended a conference where a leading Behaviour Analyst suggested that we throw out all our old literature on emotion from our bookshelves, more or less hailing the CToE as the new gospel.

So, since there seems to be no critique forthcoming, I finally bit the bullet and sat down to read the book – so that I could write one, at long last.

I chose to write it in blog form rather than a formal scientific paper, because then a) I don’t have to provide academic references for every other statement, and b) I can easily edit and revise any of the no doubt numerous mistakes and misinterpretations I’m about to make.

So, fair warning: this blog post may evolve as my understanding of these concepts change.

After all, that’s what science is all about. Trying to make sense of the world through observation, experiment and civil discussion – and our scientific ideas and theories changing over time as we learn more.

One reason I suspect that there will be revisions of this blog post is that I’m no neuroscientist or statistician. A lot of the information in the book is simply beyond my area of expertise, and I don’t know enough about the subject matter to assess whether experiments were well executed and actually measured what they claimed to measure.

But those shortcomings won’t stop me from writing this post, because I do feel confident and competent enough to raise objections to the CToE from one particular area, and that is the evolutionary perspective. Being an associate professor of ethology, I’m on reasonably solid ground here.

And from the evolutionary perspective, the Constructed Theory of Emotions is plain wrong.

And here’s why.

The evolutionary perspective.

Whenever we come up with a theory that might explain behavioural or morphological traits in humans or other animals, we must start by doing a quick check whether it makes sense from an evolutionary perspective.

Sort of like a litmus test. Does our new theory make sense? If yes, then we can move on and try to figure out the details.

If the novel theory doesn’t make sense from the evolutionary perspective, then we need to throw it out and start over.

Does the theory make sense from the evolutionary perspective?

And let’s be clear: everything in biology must make sense from an evolutionary perspective. Unless we’re counting on divine intervention or extraterrestrials to have played any role in how the human condition came about, our biological world, and humans within it, evolved under the unforgiving rule of natural selection.

Generally speaking, only the best adapted individuals survive, over time.

Typically, the way we evolutionary biologists tackle this topic is by asking a very simple question.

“Would someone with this trait do better, or worse, than someone without this trait?”

In this particular case the question would be: “would someone who constructed emotions do better, or worse, than someone who didn’t construct emotions?”, or perhaps rather “would someone who constructed emotions do better, or worse, than someone who had innate emotions?”

Which strategy is the most effective?

To answer that question, let’s do a little thought experiment.

Let’s say we live in a group of pre-historic humans.

And let’s say that, within this hypothetical group, there are, thanks to some random mutations, two main strategies with regards to emotions: a number of individuals who have the strategy of Innate Emotions, such as fear, anger, sadness etc. And one subset of the group has the strategy of Learned Emotions: they learn through experience what to do and how to name the affects they experience in different contexts.

Now, imagine belonging to the second group, and you’re standing there on the savannah, digging for some yummy roots, and all of a sudden there’s a pre-historic big cat with huge fangs rushing towards you.

The theory of constructed emotions would then suggest that you may experience an unpleasant reaction, and perhaps get increased arousal… and then what?

Without any previous experiences of being ran at by huge-fanged cats, the theory suggests that you experiment to see what works best, and learn from your actions. Perhaps try running. Perhaps try yawning. Perhaps freezing in place, immobile. Perhaps keep digging.

A thousand options. Take your pick.

And the outcomes of those options will be decided by trial and error. Sometimes you choose a good option, and succeed.

Only, and here’s the problem, in some situations, such as when a big fanged cat is sprinting towards you, the errors will get you killed. Out of the four behaviours I listed, only one is likely to lead to survival in this context – running.

But let’s say there’s another human in that pre-historic group, one that has a propensity of showing innate emotional responses, such as running-in-the-face-of-danger. Another strategy.

So, whenever that person sees a big kitty rushing towards him, he’ll get not just an unpleasant feeling, but a fear reaction, and start running. Or show another behaviour that’s part of the cluster of fear-related behaviours.

And so, the person-who-shows-fear-related-behaviours-such-as-running-from-cats is much more likely to survive a random cat attack than the person-who-experiments-and-learns-from-trial-and-error.

And in the next generation, the genes from the one-who-runs-from-cats will be more prevalent than the genes from the one-who-experiments.

Until finally, the one-who-experiments has gone extinct.

This is natural selection at work.

And that’s why I stopped reading the book How Emotions Are Made after the first chapter, because the theory of constructed emotions violates some basic tenets of evolutionary theory: the concept of learned emotions is not an Evolutionarily Stable Strategy (ESS). The moment an alternative strategy, such as having innate emotions, is introduced, it will start invading and eventually replacing the unstable strategy of learned emotions, over evolutionary time.

And again, if we want to understand behaviour, we must bring in the evolutionary perspective; the theories that we formulate must make sense when seen through the evolutionary lens.

But in How Emotions Are Made, the adaptive perspective is completely lacking. Nowhere does Barrett discuss which adaptive value emotions might have.

And that is my main concern with that book, and the theory of constructed emotions: it doesn’t make sense from the evolutionary perspective; it doesn’t even discuss adaptation in any way that makes sense.

Indeed, when Barrett mentions Darwin, it’s for two reasons:

  • Either she points out that one of the central tenets of evolution is variability. And that’s true: thanks to mutations, novel genes, novel behaviours and traits are slowly and constantly being introduced into the population.
  • She also argues that Darwin’s book the Expression of Emotions in Man and Animals is essentialist (claiming traits having defined properties), stating that “natural selection is completely absent from Darwin’s thinking on emotion”. In this statement, Barrett exposes her own lack of understanding of evolutionary processes. What she fails to mention is that the other central tenet of evolution is natural selection: that only some of the above-mentioned novel mutations survive over evolutionary time. And that most often, natural selection is not an arbitrary killer, but actually favours adaptiveness: selecting traits and behaviours that increase the likelihood of survival and reproduction of the individuals who carries certain gene variants in comparison with individuals who lack those gene variants. And, as we saw above, any mutations leading to Learned Emotions wouldn’t stand a chance in the evolutionary race against mutations leading to Innate Emotions.

Because of natural selection, certain gene variants will replace others within a population. Indeed, traits critical for survival get locked into the population; they become evolutionarily stable. Yes, there may still be variation, but that variation is around the new mean, the trait that currently survives the best in the current ecological niche. So, I would argue that Darwin’s book on emotions is not a reflection of essentialism, but rather, adaptionism. A set of emotions evolved because they had tremendous survival value for the individuals who carried those genes – at the expense of those who didn’t. That’s not to say that every single emotion felt by modern humans has tremendous survival value, but the ones put forth by Jaak Panksepp (see below) certainly does.

Also, I would argue that the variation that we see in the expression of emotional behaviour in different animals shows that it’s not a case of essentialism, but rather behaviours with similar function adapted to different ecological niches, and that these behaviours will also change through learning, too.

Barrett completely misses the significance of the adaptive value of emotions, and indeed, she doesn’t discuss how and when they arose, evolutionarily. Given that she argues that language is a prerequisite for emotions, would it be during the Cognitive Revolution, when the cave paintings started showing up, about 70000 years ago? Or would it be when the first Homo sapiens appeared, some 200.000 years ago? Or perhaps during the time of Homo erectus, a couple of million years ago? Or how about H habilis?

And how did it all evolve, which came first? The sensation and concurrent action, or the ability to name the sensation? Without both, we wouldn’t have emotions, according to Barrett. I would argue that the sensation/action came first, and the ability to name it came second. Why? Because the action associated with the sensation has clear adaptive advantage, the ability to name it doesn’t to the same degree, if at all.

In “How Emotions Are Made” none of this evolutionary perspective is present. Barrett almost exclusively discusses modern humans, humans for whom emotions serve to consider things like meeting a friend, receiving a gift, hearing favourite music, or arguing with the significant other. She discusses whether stomach butterflies are a sign of infatuation or a viral infection, or that “being angry at the boss” may take the form of silently plotting, yelling or whispering threats.

So, these are Barrett’s examples, from the human experience in the 21st century. And I would argue that these types of examples are completely irrelevant when discussing how emotions evolved. These everyday modern low-stake experiences don’t explain why emotions evolved – in high-stakes situations.

And again, we can’t understand behaviour without the evolutionary perspective, and so in order to understand how emotions came about, we can’t look at the lives and woes of modern humans, but rather we must understand human behaviour from the evolutionary perspective and ask ourselves under which circumstances emotional reactions would be adaptive, that is, save lives.

Humans evolved as hunter-gatherers, and even during most of the 10.000 generations we’ve enjoyed as Homo sapiens, life was incredibly hard: it’s been estimated that half the children born did not survive beyond their tenth birthday, and life expectancy was about 30 years. I would argue that under such conditions, we were not “architects of our own experience” as Barrett puts it, but seeds to the wind.

We’ll only understand how emotions came about if we take the evolutionary perspective: how did emotional reactions make us survive critical situations?

We can’t understand how emotions came about by looking at modern humans; I firmly believe that emotions evolved to have some type of function that saved lives in some prehistoric Environment of Evolutionary Adaptedness (EEA), and the crucially important emotions all lead to some type of physical action:

  • Running from predators (FEAR)
  • Fighting if caught by a predator (RAGE)
  • Caring for offspring (CARE)
  • Finding and securing a mate (LUST)
  • Vocalizing and actively trying to find companions if suddenly alone (GRIEF)
  • Exploring the environment and searching for resources (SEEKING)
  • Playing and having fun with others (PLAY)

The actions listed above are just examples from a cluster of potential behaviours that may be displayed for each of these contexts. The seven core emotions listed above (using Jaak Panksepp’s terminology in caps) all make sense from the evolutionary perspective: having these innate responses kick in in response to challenges will help the animal (or human!) survive and reproduce more effectively than an individual who doesn’t show these innate responses, which makes Innate Emotions an Evolutionary Stable Strategy (an ESS) – which, again, the Theory of Constructed Emotions is not.

Emotions serve to launch actions – and these actions are the difference between life or death. This, in my opinion, is how we should attempt to understand and unravel emotions. We won’t understand emotions by talking about how happy we get when we meet Uncle Kevin, or how nostalgic we feel when we remember Grandma’s baking.

Barrett writes: “An instance of emotion, constructed from a prediction, tailors your action to meet a particular goal in a particular situation, using past experience as a guide.”(p 139)

This is the key misunderstanding, in my mind: that sometimes there is no past experience to serve as a guide! This is what will get you killed when attacked by a fanged big cat. Rather, what makes sense to me is that there would be some innate predisposition to behave emotionally in a certain manner in a certain context, and then over time, as we learn and acquire experience, we may then tailor our actions to meet that particular goal even more effectively in the future.

Barrett doesn’t discuss Panksepp’s work in any length in her book, other than saying that “some scientists still presume that all vertebrates share preserved, core emotion circuits to justify the claim that animals feel as humans do. One prominent neuroscientist, Jaak Panksepp, routinely invites his audiences to see evidence of such circuits in his photos of growling dogs and hissing cats, and in videos of baby birds “crying for their mothers”. It is doubtful, however, that these proposed emotion circuits exist in any animal brain. You do have survival circuits for behaviors like the famous four Fs (fighting, fleeing, feeding and mating); they’re controlled by body-budgeting regions in your interoceptive network, and they cause bodily changes that you experience as affect, but they are not dedicated to emotion. For emotion, you also need emotion concepts for categorization.”(p 279)

I must confess I am puzzled by these statements. For starters, she dismisses Panksepp without discussing his findings that emotional responses can only be triggered subcortically in specific locations (is she saying he falsified his data, then?). Also, she acknowledges the four F – types of behaviours but claims that they’re associated with “affect” but not “emotion” without any further explanation – which in a way suggests that this whole discussion is about semantics rather than whether or not specific behavioural systems evolved to resolve different types of critical situations.

Indeed, Panksepp distinguishes three levels of emotional processing, primary level processing (the 7 Core emotions listed above and originating subcortically), secondary level processing (learning, expanding to other regions in the brain) and tertiary level processing (thoughts about emotions; involving the cortex). It would seem that Barrett only considers the tertiary level “emotions”, calling the rest “affect”..?

So, how we define “emotion” matters. In my understanding, evolution granted us some core affective reactions that have survival value and that can’t rely on words to be effective, since they are shared by all mammals. These primary level affective reactions must therefore occur without words, and perhaps then also without concepts. I choose to call these primary level affective reactions emotions, Barrett does not.

And you may think of emotions as subjective experiences, feelings. Sensations in the body and mind. The elation of joy, the pain of loss, the terror of fear. In our day-to-day modern lives, that’s often how they make themselves known, through subjective sensations.

That’s how we primarily experience them, so that’s what catches our attention. But that doesn’t explain why they evolved.

Emotions didn’t evolve so that we could just feel them.

They evolved to spur us into life-saving action. Emotion is “energy in motion” and the word is derived from a Latin verb meaning “to move.” Emotions came about as innate responses to challenges. Which is why I believe that those four Fs that Barrett dismisses as a result of affect would also be involved in emotion.

Thus follows that we should be able to find out how these Core Emotions, crucial for survival, are processed in the brain. Since they must be innate, we expect there to be different areas of the brain dedicated to dealing with these crucial challenges. Since there’s no time for learning in these crucial contexts, we expect Core Emotions to involve specific brain regions.

We don’t expect every single emotion that’s known to mankind to involve specific brain regions, but specifically those with tremendous survival value.

I can think of seven, identified by Jaak Panksepp and colleagues: CARE, GRIEF, PLAY, LUST, SEEKING, FEAR, and RAGE: the Core Emotions.

And again, Panksepp identified these 7 Core Emotions by sending small electrical currents through subcortical brain regions of multiple species of animals including humans, and noting that they all responded with similar reactions indicating similar emotional responses, each originating in a distinct area in the brain. His human subjects would show specific emotional facial expressions and report corresponding emotional reactions when each specific area of the brain was stimulated.

Note that what he found typically involved emotions being triggered in the different subcortical areas, and then rapidly spreading throughout other areas in the brain. This is in contrast to the simplified version of the “classical” view that Barrett purports in her book: as far as I understand she suggests that the classical view would view emotions as localized only to specific areas in the brain rather than spreading from specific areas.

Panksepp also found that several of the core emotions are active when animals are young, and diminish as they grow older: when higher brain functions take over, and become more dependent on learned behavioural strategies.

In the book The Constructed Theory of Emotions, Lisa Feldman Barrett completely ignores Panksepp’s and his coworkers’ 30+ years of data. She does not refute it or point out if and why it’s erroneous – she simply ignores it.

Rather, she says that there’s no evidence that specific emotions are processed in specific regions of the brain, and she bases most of that assertion on a big meta-analysis.

Meta-Schmeta.

Fair warning, I’m leaving safe ground now. I’m an ethologist, not a statistician, and even though I did study statistics as part of my phD, it was never my strong suit. So what follows could be wrong in several ways, and I’m counting on you, my statistics-minded reader, to set me straight.

A meta-analysis is a way to combine and analyze data from multiple studies. In this way, effect estimates are obtained with greater precision due to the increase of the sample size, and it’s considered the pinnacle of scientific evidence, the type of study that can decide a controversial issue once and for all. Meta-analyses carry tremendous weight and are the highest level of evidence, because they consider all the available data and pool results to summarize a whole body of research.

And that’s what Barrett and coworkers did:

“So, my lab set out to settle the question of whether brain blobs are really emotion fingerprints once and for all. We examined every published neuroimaging study on anger, disgust, happiness, fear and sadness, and combined those that were usable statistically in a meta-analysis. […] Overall, we found that no brain region contained the fingerprint for any single emotion. […] For me, these findings have been the final, definitive nail in the coffin for localizing emotions to individual parts of the brain.”(p 21-22).

So, if a meta-analysis pooling “every study” together draws the conclusion that there are no specific brain regions involved in any specific emotions, that must be true, right?

Nail in the coffin, right?

Well…

I’m having huge doubts, for a couple of reasons.

One of the limitations of a meta-analysis is that in order to be able to include data into the analysis, the data need to be similar, and measure the same thing in the same way.

The data must not be heterogeneous, as it were.

If it’s heterogeneous, the variability in the data will obscure any true findings, and we risk a false negative outcome.

Apparently it’s one of the more common mistakes people make when conducting a meta-analysis: combining heterogeneous data. And still they get published: over 50% of publications within the medical field have faulty statistics (bad experimental design, data collection, choice of method, interpretation).

Chew on that for a bit.

50% of published statistics faulty – at the very least. So we should always be critical thinkers when faced with statistics, even in peer-reviewed published papers in prestigious journals.

So, rather than taking Barrett’s meta-analysis at face value, I questioned it. After all, it only had less than 50% chance of being correct.

And after reading through the abstracts of the 60 first references of the studies included in the meta-analysis, I quickly discovered that the data included were not measuring the same thing, and they were also not collected in the same way; rather it was extremely heterogeneous.

Here’s how emotional reactions were triggered in some of the studies in the meta-analysis, using either fMRI or PET (measuring blood flow versus blood oxygenation):

  • Film-induced sadness/amusement
  • Looking at neutral and negative scenes
  • Looking at angry and fearful faces / sadness
  • Looking at happy/fearful faces and hearing happy/fearful voices (or mix)
  • Passively viewing emotion words
  • Matching emotional face with words
  • Viewing photo of beloved while being in love
  • Watching a filmed bank robbery in which they had been the victim.
  • Recalling emotional situations that they have lived through: (sadness, happiness, anger, fear, disgust)
  • Listening to an autobiographic narrative meant to cause anger
  • Listening to angry prosody in meaningless speech
  • Olfaction / tastes and core affect space
  • Pairing faces to neutral, pleasant and unpleasant odors
  • Listening to music that produces the chills
  • Mentally preparing a speech to be presented to a panel of professors and experts
  • Comparing depressed / healthy people viewing sad film
  • Comparing panic disorders/ controls viewing anxiety-inducing images
  • Comparing borderline / controls viewing aversive and neutral images

In other words, the data was all over the place, both with regards to measuring technique (fMRI versus PET), which purported emotion they were measuring, how that emotional reaction was triggered, which sensory system was involved in processing the trigger, whether the study involved primary, secondary or tertiary level emotional processing, whether the studies looked at emotion experience, perception, memory or categorization, as well as the emotional baseline state of the person when the experiment started.

Not to mention that all of these were carried out on humans who were aware of being part of an experiment, so one might question perhaps how authentic the purported emotional reaction would be to, for instance, listening to an autobiographic narrative meant to cause anger in such a highly contrived scenario. Might we expect “real” anger to be triggered and processed differently in the brain? And is a social evaluative threat, fear of giving a speech in front of an audience, really fear – or some other emotion, such as embarrassment?

In other words: garbage in – garbage out.

Meta – Schmeta.

Just because you can throw a bunch of numbers into the same mathematical pot, doesn’t mean you should.

Another problem I have is that the findings of a particular meta-analysis may be valid only for a population with the same characteristics as those investigated in the study. In other words, the results of Barrett’s meta-analysis would be valid for people undergoing this type of contrived experiment, where “emotions” (if that is indeed what they are) are triggered by images, video, odors or sounds while strapped into a laboratory apparatus. We can’t extrapolate to real-life situations, because that’s not what they studied – and we don’t know how well biologically meaningful situations correlate with these artificial experimental set-ups.

Also, due to ethical reasons, truly distressing emotions are never evoked in these types of experimental studies included in the meta-analysis – so we simply don’t know what goes on in human brains experiencing intense negative emotions.

Another issue with Barrett’s nail-in-the-coffin meta-analysis that I’m really hesitant about is virtually dividing the brain into tiny 3D-cubes (voxels) to make sense of the data:

“For every voxel in the brain during every emotion studied in every experiment, we recorded whether or not an increase in activation was reported.”(p 21)

I have two problems with the voxel approach: one is that the chosen size of the voxels will influence whether activation in that particular voxel occurs or not. If voxels are really large, they would activate often, and if extremely small, they would activate seldom, so the selection of voxel size will impact the outcome in ways that may be hard to predict.

Secondly, since no two human brains are exactly similar in structure, a specific voxel, if small enough, may be located in different structural regions in two brains. So, even though the same brain region were activated in both brains, different voxels would be activated. To me this voxeling approach seems like a blunt tool that increases variability, which increases the risk of a false negative finding even without the heterogeneity mentioned above.

Indeed, in chapter 11 Barrett writes: “No two brains are exactly alike. They generally have the same parts, roughly in the same place, connected together in pretty much the same way, but at a fine-grained level, in their microcircuitry, they have vast differences” (p 230). This statement, to me, completely invalidates the voxeling approach.

Meta-analyses are a controversial tool, because even small violations of certain rules can lead to misleading conclusions. Since multiple decisions when designing and performing a meta-analysis require personal judgment and expertise, there is a substantial risk of personal biases or expectations influencing the result. Omitting Panksepp’s data altogether (they were indeed missing despite the claim to include every published neuroimaging study) while throwing in a heterogeneous bag of other studies is a way of cherry picking data that concerns me, and I would suggest that the findings reflect the biased selection of data, the heterogeneity, and the voxeling.

There’s simply too much noise in the data. The risk of a false negative is overwhelming.

Also, in the meta-analysis they tested the assumption that each emotion is processed only in one specific brain area, calling this the classical, locationist perspective, and they took any failure to find such associations to mean that emotions would be constructed, rather than innate. An alternative explanation may be rather that emotion processing is not limited to a single location but rather part of specific networks connecting several regions, extending throughout the brain. It would make sense that brain regions do not have function in isolation, but rather in the context of the networks to which they belong.

Others have criticized Barrett’s and coworker’s meta-analysis, and one of the most convincing arguments that I found was put forth by professor Andrea Scarantino:

The authors “…are open to the possibility that there may be “widely distributed” networks for discrete emotions, but argue that their existence “would be consistent with a psychological constructionist … view” (sect. 6.1, para. 4). I strongly disagree. Constructivism posits that discrete emotions are not causal entities in their own right, but rather, effects of more basic psychological processes. The existence of networks for discrete emotions would strike at the heart of this idea, vindicating instead the natural kind proposal that discrete emotions have ontological status as causal entities and are driven by distinctive, though distributed, neural mechanisms. [The authors have] built their argument such that if criteria for the locationist argument are not met, it is assumed to be support for the psychological constructionist perspective. This is misleading, and fails to recognize other possible explanations.”

Another shortcoming of the study was that fMRIs typically only capture the initial response to an emotional stimulus, and we know nothing of what happens over time; this type of measuring technique doesn’t capture the development of the emotional experience beyond the first second. Panksepp typically used PET studies rather than fMRIs, much for this reason if I’m not mistaken.

To summarize, it’s not surprising that the meta-analysis found nothing, or rather, it found a huge variability in how emotions are processed in the brain, given that the included data was too heterogeneous; despite the heterogeneity there was still cherry picking with critical studies omitted; the use of voxels rather than comparative anatomy may obscure any real findings, and we don’t know how well the contrived experimental set-up translates to real-life emotional reactions.

So, there’s no way of distinguishing whether those results were a false negative or a true negative result.

For me, Barrett’s meta-analysis was by no means any nail in the coffin with regards to how emotions are processed in the brain.

Yes, that’s a harsh judgment coming from someone who doesn’t know much about statistics. I’ll grudgingly change my mind if you prove me wrong, though!

And even if I didn’t have these glaring objections to Barrett’s meta-analysis, I would still be concerned.

Why?

Because I would expect the brain to be involved, in some way. Since in the previous section we discussed the need to run from big fanged cats, that needs to be choreographed by the brain, without prior learning, somehow.

Yes, I would expect learning to occur, naturally, but I’d also expect innate emotional reactions orchestrated by different sections in the brain.

In other words, I’d expect to see what Panksepp actually did find.

Barrett writes: “I sometimes hear comments from emotion researchers who subscribe to the classic view: “what about these other 50 studies with these thousands of subjects, that show incontrovertible evidence for emotion fingerprints?” Yes, there are many such confirmatory studies, but a theory of emotion must explain all the evidence, not just the portion that supports the theory”. (p 22)

She makes a valid point that all evidence must be explained by a theory of emotion. But to me it seems that the studies of emotions in the brain carried out to date don’t lend themselves to a relevant meta-analysis, since they’re too heterogeneous, and any selection of studies to include into a homogeneous meta-analysis would be biased one way or another and contain only a fraction of the studies carried out.

Meta-analyses for emotion studies are a catch 22, as it were. The data is too variable, so either a meta-analysis will be homogeneous and therefore biased, or it will be heterogeneous and we risk false negatives due to the noise in the data.

Also, one disturbing omission in the book is a discussion on neurotransmitters. Barrett searches for, and dismisses, “fingerprints” on emotions related to facial expressions, and brain areas involved in emotions. But she doesn’t address what we know about neurotransmitters associated with emotions (oxytocin, dopamine, endorphins, and endogenous cannabinoids to mention a few), how they are involved in emotional reactions or how the synapses where they take action are distributed throughout the brain. How well do these findings reconcile with a Constructed Theory of Emotion? I suspect not well at all, but I could be wrong.

Let’s leave the brain behind and move on to another topic: whether facial expressions are innate or rather learned, as suggested by Lisa Feldman Barrett and the Theory of Constructed Emotions.

Facial expressions

In the book, Barrett shows snapshot images of partial facial expressions, making the relevant observation that we can’t reliably decode an emotion from seeing an image of a part of a facial expression.

Rafael Nadal winning the Olympic Gold Medal. One may mistake his facial expression for terror if one doesn’t have the whole context.

Barrett then goes on to make the case that we can’t tell emotions from facial expressions because they’re too variable, and it’s only in context that we understand what the person might be experiencing, and on top of that it’s only if we share similar learned expectations about what facial expressions should mean (smiling means happy, frowning means angry, etc) that we can interpret them.

I disagree.

Rather, I would say that we didn’t evolve to decipher emotions from snapshots of partial facial expressions, so we shouldn’t expect to be able to do that. We evolved to understand a subset of facial expressions unfolding in real life and over time in relevant contexts.

Again, everything in biology must be understood from the evolutionary perspective.

So, the crucial question is: when would innate facial expressions be adaptive? If we look at what type of situations that we would expect to result in adaptive stereotypical facial expressions or body language signals, it would be in some social contexts, such as to signal intent (benign or malign), as well as to realign the face or body to better deal with environmental challenges (the scrunchy nose face that’s often associated with disgust for instance, may serve to close the nasal passage protecting it from dangerous fumes, and squinting our eyes shields them from damage).

And in my understanding, the human smile doesn’t mean “happy”, it’s a social signal of benign intent. From the evolutionary perspective, it’s highly adaptive to be able to recognize if a person has benign or malign intent even from a distance, and so we would expect that there would be a selection pressure favouring that type of signaling.

But again, the adaptive perspective is completely lacking in Barrett’s book. She simply concludes that decades of studies of facial expression are faulty, that we learned to smile by watching TV, and so she rejects the notion of innate facial expressions altogether.

In Barrett’s words, according to the classical view,“emotions are supposed to have universal fingerprints that everyone around the world can recognize from birth”. (p 43)

I’m not sure who claims this – who makes that argument? Over and over while reading the book, I get the feeling that much like Don Quijote, she’s tilting at windmills. She’s attacking a straw man, one that doesn’t exist. The simplistic “classical view of emotions” that she attacks isn’t actually argued by anyone, as far as I’m aware. There are more than 92 definitions of “emotion” in the scientific literature – which is the “classic” one?

As to her quote above, from the evolutionary perspective, I would neither suppose that every single emotion is matched by a specific facial expression, nor that we could necessarily be able to recognize those expressions from birth. There’s no adaptive reasoning that would suggest that any of those two statements would be true.

I won’t go into much detail of Barrett’s arguments here, but Paul Ekman defends his research on facial expressions here, and a Nature paper summarizes much of the controversy here.

Here’s a passage that I had to read several times, though, feeling my jaw drop.

“The historical record implies that ancient Romans did not smile spontaneously when they were happy. The word “smile” doesn’t even exist in Latin. Smiling was invented in the Middle Ages and broad toothy-mouthed smiles […] became popular only in the eighteenth century as dentistry became more accessible and affordable. The classics scholar Mary Beard summarizes the nuances of the point: “This is not to say that Romans never curled up the edges of their mouths in a formation that would look to us much like a smile; of course they did. But such curling did not mean very much in the range of significant social and cultural gestures in Rome.” “ (p 51)

I’m not sure on which data this classic scholar rests the conviction that Romans didn’t smile, but in my mind the only two relevant sources might be literature, or art.

I would not take the lack of discussions of social smiling in the Roman literature to necessarily mean that people didn’t smile: the absence of evidence is by no means evidence of absence.

But even more importantly, I can think of one huge reason why smiling would be expected to be absent from Roman art: because smiling would indicate benign intent. And when you’re getting your formal portrait made, whether you want to come off as powerful or friendly will surely differ depending on the cultural climate. And I can think of no epoch when the projection of power were more important than during the Roman era.

The Roman emperor Caracalla. Friendly or powerful?

We always need to think about alternative explanations to our observations, and the lack of smiling portraits or sculptures from the Roman era might either mean that people didn’t smile at all, as Barrett assumes, or that smiling wasn’t something that was captured in art during that particular era – which in my mind is a vastly more plausible explanation.

As to the statement that “the word “smile” doesn’t even exist in Latin”, what about subridere? Does it not mean “smile”, or is it not Latin?

Silent bared-teeth displays, signaling benign intent, is shown in gorillas, chimpanzees, orangutans and macaques – our closest relatives. To suggest that smiling in humans came about in the Middle Ages doesn’t align well with these comparative findings.

Silent bare-teeth displays in primates tend to signal benign intent (in the contexts of greeting, submission, or sexual behaviour, for instance). It’s been hypothesized that the silent bare-teeth display is the precursor of the human smile, and that the relaxed-open-mouth-display (not shown here, but also seen in many primate species in playful situations) is the precursor of human laugher.

In my opinion, Barrett throws the baby out with the bathwater by suggesting that all facial expressions are learned, rather than some being innate.

Besides, if emotional facial expressions were truly learned, surely there’d be more variability? Would smiling-when-in-a-good-mood or frowning-when-annoyed be that ubiquitous, seen in all cultures around the globe? If they were truly culturally transmitted, wouldn’t we expect as much variability in facial expressions as in, say, language?

The importance of the discussion climate

So why did it take me 3 years to read How Emotions Are Made? Well, to me personally it was an extremely aversive read, and after the first chapter I put it aside and kept stewing over it for a very long time before I picked it up again, months later. Here are the main reasons why it was so difficult:

  • Barrett challenged my core beliefs: I’m a firm believer in emotions being innate, and she kept telling me I was wrong.
  • Her tone of voice while telling me I was wrong was extremely condescending, and I’m a sensitive person prone to indignation and affront when patronized. My adrenaline kept spiking, so I kept putting the book down.
  • I felt myself disagreeing with many of the scientific studies reported in the book (I’ve only mentioned a few of those disagreements in this blog post, but there’s more!), which made reading on very difficult because I got so biased to thinking that I would continue to disagree. I actually found that I was mostly in agreement about chapter 9, though!

So, rather than convert me, the book did the opposite: I finally plowed through it on sheer willpower (lots of chocolate as reinforcement after each chapter), and put it down being even more convinced that I was right. I realize this might sound like quite the absurd reaction, and part of it has to do with the Semmelweiss effect and the backfire effect, two cognitive biases that both kicked in.

But also, I truly believe that the Constructed Theory of Emotions is flawed. Those cognitive biases merely exaggerated my reaction to the book.

Lisa Feldman Barrett concludes in her book that “based on overwhelming evidence, the classical view has lost”. (p 152)

I’m actually underwhelmed, and remained unconvinced by most of the evidence she puts forth; my paradigm hasn’t shifted. But she doesn’t invite discussion, but rather accuses people subscribing to the “classical view” of the mental inference fallacy, and of being unscientific:

“When mountains of contrary data don’t force people to give up their ideas, then they are no longer following the scientific method”.(p 173)

I find that statement extremely triggering. I am following the scientific method to the best of my ability, and I’m also questioning her theory.

But although I’m guilty as charged, I’m most certainly biased by the mental inference fallacy, that’s not the reason I’m disputing her claims. I dispute them because I don’t think that the Constructed Theory of Emotion is based on any solid science, and that what is needed here is discussion, not polarization and condescension of the opposing viewpoints. Any Theory on Emotions should incorporate all the main findings and still make sense from the evolutionary perspective – without ignoring Panksepp’s and others’ large body of work. I just don’t think that meta-analyses are useful for this discussion since we risk either false negatives, or biased selection of data.

To me, the Constructed Theory of Emotions is about how we think about our emotions, and how we classify them. Not what triggers them, and how we respond to them – which behaviours we show, or what the outcome of those behaviours are; how they were once (and perhaps still?) adaptive.

How about you? What do you think?

  1. Thanks for writing this as it’s helpful to further a discussion. I won’t tackle all of your criticisms as that would be lengthy.

    A critique that seems to not “land” well about ToCE is that other mammals/animals don’t have emotion because they don’t have human language. While I quibble with this because I follow a non-materialist philosophy of panpyschism where *everything* has consciousness….it doesn’t mean ToCE is wrong. To me it means her understanding of consciousness and more-than-human language among other animals is lacking.

    Dr. Barrett never said animals don’t feel.
    Physiological affect, or “mood” or “feeling states,” are foundational precursors to emotions carried by the nervous system up to the brain in a ongoing feedback loop. Hunger, thirst, agitation, etc. are feeling states, not emotions. These are part of ToCE theory. Fight/fight/freeze/fawn are nervous system states. Fear shows up *after* the nervous system is already activated. Animals absolutely escape danger because of that nervous system activation.

    What she’s pointing out is that in her opinion because animals don’t have human language they don’t have these same concepts. I disagree with her because other behavioral research seems to indicate that animals absolutely can learn some human words/concepts (e.g. dogs linking sounds with words in order to communicate using those sound boards).

    I find this a small side-bar conclusion though, not critical to the main theory, and not one that causes me toss out the rest. She’s a neuroscientist and a psychologist looking to understand human emotions – not an animal behavior researcher. While humans are mammals, and therefore animals, we use different forms of language that others do not use which sets us apart.

    I recommend reading her research publications rather than the just the book as the actual research articles are more clarifying than what she wrote as popular fiction. I found your argument that she ignores the adaptive capacity and the evolutionary foundation of the theory puzzling – as my read of the research is the opposite to your conclusion. Language/culture is part of our adaptive response which is encoded in emotions. Survival though happens at the level of nervous system mobilization. People who survived ongoing dangers are those who had a body that got them out of the situation (nervous system mobilization) and the learning capacity to remember what worked. Her research articles talk about this and discuss neurons at length. Here’s the one that goes over the theory which she turned into the book: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5691871/

    In particular I appreciated the study which revealed different portions of the brain lighting up based on different recorded emotional states indicating that while the amygdala is part of emotional processing that is continually assessing uncertainty/familiarity, it’s not a “switch” or trigger that’s always turned on when fear shows up. Fear is often experienced without the amygdala involved. https://www.sciencedirect.com/science/article/abs/pii/S0959438813000172

    The main reason I found ToCE so compelling is that it sums up the predictive capacity of the brain which is part of what makes us so efficient, and so prone to mistakes and bias errors (which are also learned) which you don’t talk about much here and is absolutely an evolutionary explanation.

    As a complex trauma survivor, ToCE made a huge difference in understanding the emotional patterns that arise in various circumstances that other theories didn’t touch based on a) past learned associations, b) current environmental sensory inputs from outside the body, c) current internal affect sensory inputs from the body, and d) where attention is resting (which affects the other 3). It helps explain why people in the exact same circumstances/situations do not have identical emotional responses. And why I experience “extreme distressing emotions” in situations like those of the research subjects where the various studies are using a multiplicity of different sensory inputs as part of understanding emotional outputs. I experience them because of a history where similar sensory cues put me physical in danger repeatedly.
    Her science methodology critique of Ekman’s work was particularly insightful. If you only keep in people from cultures across the world who can positively match the faces to the emotions YOU TEACH THEM in research studies about the same topic… then of course it will seem that everyone recognizes the same facial expressions.
    I also loved her recent movie on it in particular where she expands on how faces, with context removed, are nearly impossible to interpret, https://www.youtube.com/watch?v=0rbyC5m557I .
    And am a big Sanderson fan 🙂

    1. Thanks for sharing your thoughts and insights!

      I’m quite sure that the aversive experience I had reading biased me quite severely against the potential merits of this theory, some of which you touch on – and she might be more nuanced in other publications, for sure.

      Seems a lot of the disagreement stems from our definitions. What is “emotion”? Depending on how we define it, we’ll come to vastly different conclusions.

      As to the adaptive perspective being addressed by her, I think the quote I used shows that it’s misrepresented: “An instance of emotion, constructed from a prediction, tailors your action to meet a particular goal in a particular situation, using past experience as a guide.”(p 139). She’s saying the action (not the emotion) is learned, not innate.

      Also, after reading through some of the studies in the meta-analysis I got really suspicious about the definitions of different emotional states. What is “fear” – and how was it provoked? By watching images, hearing sounds, remembering past events, being socially embarrassed? I would not classify all of these instances as the same thing.

      … eagerly awaiting Sanderson’s next installment in the Stormlight Archives..! 🙂

    1. A difficult question, for sure! Human society today is nothing like the EEA (environment of evoluationary adaptedness) that we evolved under, which is one reason I think we’re so maladapted to modern life, get stressed and depressed – and sick. And yes, modern medicine, wars and climate change will all to a bigger or smaller degree influence which genes continue into the next few generations…

  2. That’s a great post. Thank you for sharing your thoughts on this. I haven’t read her book but read many of her scientific articles and I agree that her theory is flawed.
    Are there any recent scientific articles you could share that challenge her views?

    1. Vivo- thanks! I’m not on top of this literature in the last year, but apart from a chapter in a book I haven’t seen any direct challenge: Asma and Gabriel, The Emotional Mind (Harvard, 2019), pp. 10-13.

  3. This is an excellent and needed post. I am an emotion researcher and frequently find this idea frustrating (the theory also tends to put too much emphasis on the brain rather the contexts especially, evolutionary relevant contexts). Really wish this could be published to a wider audience

    1. Thank you so much – glad to hear it resonates! I would perhaps be open for co-authoring or putting my name on something along these lines in an academic paper if you think that would be of interest? I’m not in academia anymore so wouldn’t have much time for it, unfortunately.

      1. I am not sure I can commit really sorry. Also, one big problem is that theory mischaracterises other research. For example, the wiki entry to ToCE says “Most other theories of emotion assume that emotions are genetically endowed, not learned, and are produced by dedicated circuits in the brain: an anger circuit, a fear circuit, and so on.” The first problem with this is that “genetically endowed” is not the opposite “learned”. A second problem is that “fear circuit”, “anger circuit” etc refer to theories of the brain representation of emotion. You can take an evolutionary perspective that emotions (discrete or not who cares!) evolved in specific situations to solve specific problems without committing to some discrete set of neural circuits. I am sceptical whether there is a specific brain circuit for anger (evolution tends to share structures for different purposes) but I do think that we have an evolved (e.g., there is a genetic basis) tendency to fear spiders, become “jealous” (or aroused an unpleasant if you really want to avoid basic emotion terminology) in specific situations and not others. Often feelings just emerge in situations even when we do not have a label for them – think about how teenagers with limited exposure to cultural shared information become jealous or lonely for example.

        1. No worries – I wrote a blog post because I didn’t have time for an academic paper, so I know exactly what you mean – and yes it seems that any weighty critique on the ToCE would have to have many areas of concern to discuss..!

  4. Hi Karolina

    Great thanks for writing this blog post. I discovered it because I needed to ventilate after reading another text from LBF published today at The Guardian saying again that animals have no emotions – https://www.theguardian.com/books/2022/aug/29/the-big-idea-do-animals-have-emotions

    I felt sad because I’ve recently read “Mama’s Last Hug” (2018) by Frans De Waal and understood all his embarrassment to say that animals have emotions. He talks extensively about LBF, and also LeDoux who changed views recently, however by the end of the book De Waal is very clear, there’s no way animals have no sense of emotion. Work of decades of relations with primates exemplify it without any margin of doubts.

    I remember when I read this book from LBF I felt exaclty the same as you. I’ve researching emotion for the past 15 years related to the way we interact with machines, and I couldn’t believe what Lisa was saying. More even, couldn’t believe all the applauses she was getting with these perspectives.

    I myself also decided to write a blog post in portuguese. You can read it through google translation to english here: https://virtual–illusion-blogspot-com.translate.goog/2018/12/a-construcao-inata-das-emocoes.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en

    I pointed out different problems in her reasoning but one of the most shocking is looking at facial expressions in the visually impaired, in many of reasearch studies made. If the emotions are only learned through interacting with others, how have humans with congenital blindness learned them?

    all the best

    1. Nelson, thanks for reaching out – so glad you enjoyed my post! Google translate is a fantastic thing – it’s mindboggling that I can read an article written in Portugese (the only obvious mistake google did when translating was calling Lisa “he” throughout – as expected since you often don’t write pronouns in Portugese and Spanish)). I think this really illustrates the need for different behavioural disciplines to come together and discuss – your angle of approach and criticism complemented mine nicely! 🙂

      About Barrett’s novel paper, what can I say..? “the three examples have virtually nothing in common physically. They involve different kinds of brains in different situations, moving different kinds of bodies in different ways.” Actually, Panksepp showed that they had a lot in common, homologous brain regions involved in the different emotional states, and the responses can be categorized in similar groups (although different species evolved to exhibit slightly different clusters of fearful behaviour, freezing and fleeing are seen throughout the animal kingdom). We expect similarities based on shared ancestry, but we also expect variability due to the passage of evolutionary time. Barrett points at the variability but fails to notice the similarity.

      Good point about blind people still expressing their emotions in their face. I guess a critic would say that it’s due to social reinforcement that they’ve developed crying-when-sad for instance, but if that were the case I would expect a lot more local variability, sort of like languages.

  5. Thank you for this post. I wanted to summarize what I think is going on here, and please tell me your thoughts.

    Feldman is guilty of the strawman fallacy. She desparately wants to claim that human emotions are not universal. But I think most universalists would allow for variation. As far as I can tell from the evidence, she has only proved that how we generate emotions, both physiologically and facially, are variable. That is, there seems to be deviation from Ekman’s universal emotions. These deviations form a family of curves but all relate to their prototypical emotion. To me, this is to be expected and does not prove that emotions are not universal, only that there is variation from their respective protypical emotion. So there is no exact fingerprint but only instances of a theme. I recall a study that graphically demonstrated this.

    The second fallacy that she commits is the overgeneralization of innateness. She desparately wants to claim that emotions are not innate. What is more likely is that some parts of emotions are learned and other parts are not. None of the evidence that she has provided proves that the physiological apparatus that generates the emotions are not evolved psychoogical mechanisms. The evidence only says that we quickly learn emotion-based concepts. In order to pass on these emotions, someone at one point in time must have generated the first prototypical emotion. Why did they generate that emotion (one of the universsals) and not another emotion? It is because these emotions have survival value. The function of an emotion is always the same. Take the emotion anger which always involves a threat to our wellbeing/status or represents that we are losing in some situation. This is invariable across cultures. So is the emotion of shame, etc. The implication is that there must be a genetic basis to these mechanisms that conferred a survival value.

    Although I think that the crux of her constructivism based hypothesis is probably correct, this does not mean that the underlying mechanisms that generate emotions do not have evolved components. Please tell me if I am on the right track here. I am an electrical engineer who reads a lot of psychology text books, but this is not my formal discipline.

    1. Jonathan, thanks for sharing your thoughts on this!

      I agree – I would expect nature and nurture to interact, for sure. Innate predispositions that get tweaked through individual learning experiences and culture. I would expect variation to occur around the mean of each emotional expression, so not complete inversions (for instance, I can’t imagine that a frowning face would be interpreted as a happy inviting one in any culture). That’s what would make sense – and what we see, too, I would argue.

  6. Thank you for this excellent and well-written blog entry. I would just like to link for you this response by professor emeritus Roland Meyer to Beard’s contention that the Romans didn’t smile:

    https://classicsforall.org.uk/reading-room/ad-familiares/roman-smile

    Also, it occurs to me that Latin words for smile and laugh are seen today in languages like French (sourire / rire).

    One concern I have with constructivism, and arguments such as the one that smiling only emerged in the Middle Ages, is that it aligns with a critique of Ekman that came earlier from the field of cultural anthropology and Catherine Lutz, who also had a run-in with Ekman. Basically the argument is against universalism and in favor of cultural diversity: a Japanese smile doesn’t mean the same thing as an American smile. True in some cases, yes, but not all. These arguments however can have the effect of orientalizing non-Westerners just as they separate humans from non-human mammals. In my opinion, they can go way too far: we have to acknowledge such cultural differences while still recognizing cross-cultural similarities based on biology and evolution.

    1. Brendan – thanks for the link, most interesting!

      And I am in complete agreement as to the importance of acknowledging cultural differences while still accepting our common ancestry. It’s not nature OR nurture – it’s nature AND nurture…!

  7. I am an anthropologist. I do not find this either/or thinking productive. Understanding emotions as BOTH evolutionary AND constructed gives us a way to address the complexity of emotional behavior and experience.

    Your argument is that the main element absent from Barrett’s book is an evolutionary perspective. This is a fair point. The main element absent from YOUR response is the role of culture. Human beings do not live the way they did thousands of years ago. We live in a range of culturally and socially complex and diverse environments that have changed over time and that can change over the life course of an individual. Barrett’s analysis allows for & addresses that complexity. Your analysis does
    not. Evolutionary perspectives are useful. Relying on them to the exclusion of other perspectives and in ways that erase culture and history is not.

    1. Hi Di, and thanks for your comment! I agree with you – culture and history are tremendously important in understanding contemporary human behaviour! That’s not the topic of this blog post, however..! 🙂

      To better frame the context of this blog: I write about animal behaviour and welfare, and thus the cultural perspective is less interesting when viewing behaviour from that standpoint.

  8. A great post, and I agree with every word of it: thanks so much for doing it. As you point out, her theory simply does not make evolutionary sense. And her omission of all the neurotransmitters and neuromodulators such as serotonin and dopamine that we know are invoved with felt emotions is extraordinary. They exist for evolutionary reasons: they make us more likely to survive. Very inconenient for her theory.

  9. In Science magazine there appeared an article, The Last Human, which pivots on why we’re the only remaining “human-type” species. They conclude, among other things, that we were more successful because of having emotions and “wanting to help each other succeed”, hence the vast improvements in our ability to communicate.

    It’s tough to link emotions to evolution, because with modern bioinformatics, DNA/proteins/gene should contain incontrovertible proof of a concept if people will want to accept it. On the other hand, some of us understand well that scientific evidence for some things will not materialize in our lifetimes, but there exists many other kinds of proof for things that we’re somehow ‘convinced’ must be the case, for example, that emotions have a strong role to play in our “dominance” over other animals, or that emotions make us more vulnerable and more fearful and therefore make us act out much more strongly to perceived threats (even if they do not exist as perceived).

    It’s a rich discussion, and an important discussion. Science friends of mine deny it, because of “the lack of data” (this is my main problem with colleagues in the academic research community). With mammals, emotions are more prevalent compared to other species, I’d say, also because “lower species” (evolutionarily speaking) do not have the “mammary glands” (needless to say?). An interesting point that latches onto elements from this insightful post is the issue of how emotions are thought to have led to our continued existence as a species, as opposed to the extinction of other hominoids who also had similar traits but still could not compete with us. Did emotions have such a large role to play? Really, and can we prove it, at least theoretically? I would put forward the idea that we make “emotionality” a central theme when discussing mammals, also due to our closeness to mammalian pets, and look at the matter from such an “emotion-driven” point of view. Did genes mutate differently due to emotions? Were traits inherited differently due to emotions? Etc.

    The comment made by Hertha James is a great case in point: dogs certainly have amazingly well-developed sets of emotions. They understand nuance, without having the language we have. Is any of such a trait important for the species? For its survival? Is it somewhere imprinted into the genomes of individual dogs, and can the offspring inherit these enhanced nuances for emotional connections with carers? I’m trying to drive at natural selection for emotional intelligence without saying there is natural selection for emotional intelligence, but I still believe that there must be something to this effect – to my scientific friends, I should deny that emotions could have the slightest chance of being as real as DNA and other “stuff like that”. I hope I’m not confusing you, but the conclusion here is that I support your well-reasoned rejection, and offer in support the idea that emotions are much more central to us mammals than what popular science makes us believe. Granted all the media hype these days, many well-known men in the science offices will not like it if “emotionality” is proven to be the key to advancement and survival of our species. That would mean that “You’re Emotional” could be an empowerment phrase rather than the derogatory slants it is commonly associated with. But let me not drive myself off-topic. As I said, it is an important discussion. And I just love that you make such effort to include your readers. Fascinating.

    1. Nathaniel, thanks for sharing your thoughts on this topic! 🙂 Glad you liked this post.

      Indeed, I do believe that “emotions” (and I think we need to explain what we mean by that term, since there are apparently more than 90 definitions out there) have a huge impact on our perception, decision making and behaviour.

  10. Wow, so glad to read your blog. I am an editor of a popular scientific magazine in the Netherlands and we were considering Lisa Feldman Barrett for an expert interview. Some famous Dutch authors are calling her book a revelation etc. But whatever I hear and read about her so called groundbreaking new theory just doesn’t convince me. I have a background in the psychology of emotions and evolutionary psychology, and to me it looks like she creates some kind of illusion that everyone falls for! I felt like I was the only one shouting the emperor is naked – but thanks to you I know I am not alone 🙂

  11. I really enjoyed reading your blog. In a psychology group we have been looking at her book “ seven and a half lessons about the brain”. Half way through the first section I became absolutely sure that what she is spouting makes absolutely no sense. I am not a qualified scientist, but a very curious person who studied science at school. It did not take me long to have serious doubts about her assertions that predictive processing is the only processing the brain uses. That just makes no sense on all sorts of levels. I was told that it would not be efficient for the brain to use multiple systems. Why? is my answer to that statement !

    1. Thanks Shirley! I suspect that there’s a lot of grumbling going on in the neuroscience community on this topic – would be interesting to see some public debate..! 🙂

  12. Thanks for that post. I was wondering whether I am the only one thinking that she is arguing a strawman. I always thought that emotions are mapping culture on top of feelings. feelings are innate and emotions very much more finely grained because we developed language, a much better communicator than facial expressions. So in that sense both is true, we have some limited number of feelings that are innate including facial expressions. But our world became much more complex (and we more intelligent) so that we developed spoken language and were able to describe feelings much more granular. And different languages use different words thus associated different things. Makes sense to me. I am not using the terms feelings and emotions correctly (I in fact was completely oblivious to the actual meaning but just read about it), but does that make sense to you when we say: course grained emotion= innate, finely grained emotions=cultural.

    Best, Ben

    1. Ben, I think you’re spot on, there’s both – regardless of what we choose to call it! Panksepp calls both the innate sensation/action as well as the cultural/cognitive processing emotion (but he distinguishes between primary, secondary and tertiary emotions). Seems that Barrett calls innate sensations affect, and cognitive processing emotion. Which suggests that a lot of the controversy is simply semantics… 😉

  13. Yes, they do have a “toothy grin” – negative high arousal, but more with the intent of fleeing comes to mind. You see them when dogs are for example fearfull of thunderstorms and such. They will also be panting and may be drooling. The difference is in the eyes and ears. Ears will be in the neck and whale eyes. Posture of the dog will also be croached.

    What a lot of comments since my last visit…will need to take some time to go through these… Thank you for you valueble contribution as always.

    1. Thanks for clearing up the difference – and yes this blog post got a whole lot of attention!! 🙂

  14. That the brain is a dynamic predictive organ is well established in the field of Neuroscience and not even a new idea. Check out the writings of Kant, William James, Von Helmholtz….
    Since you don’t list any references at all I’m not sure what “bad science” you talk about.
    Nor are any of the psychological phenomenon the scientific forefathers talked about grounded to the brain. The word Emotion itself is an emperialistic idea.
    While the Greeks debated about the passions… none grounded to the brain as so well pointed put in Buzsaki’s “thr brain from the inside out”.
    You can certainly argue that Panksepp grounded his emotion hypothesis to the brain. But did he really?? You cancertainly find out what certain brain areas are involved in in computing but what one is left with is what the rest of the network does in which other downstream neurons of other areas are firing- and really its not like Barrett doesn’t explain in detail in the book and the Scientific Papers how the brain predicts; the book and her paper lists a mountain of emperical papers to follow up on. And these papers themself list mountains of other Scientific references to research on.
    I also find it worrying that her work is so mis-represented that the commenters suggest her ideas suggests “specism”. She actually continually writes the opposite- that brains didn’t evolve for the human brain as the pinackle but that every brain has its specialities, BECAUSE, any species brain is special in regulating and controling its body in the niche each species moves in.
    Even Jo LeDoux is constantly pointing out the constant mis-use of his work on threat responses (which he used to call fear responses)
    He is very outspoken about it these days.
    What I find interesting is that this is communicated through a blog. Even Panksepp engages with Barrett – he was actually invited years ago at the University she is at to debate for several weeks- out of which a couple of very neat sientivic debates/articles were the released.
    Thus wouldn’t it be of more use to actually write a scientific article and do some deep research, then to write a blog were mostly people who belief in your views are commenting and some of them in a rather disrespectful way.
    Best wishes
    Bono

    1. Correction in scentence:
      “Panksepp engages with Barrett” was meant to spell past sense:
      “Panksepp engaged with Barrett & Co…”
      Regards
      Bono

    2. Thanks Bono. I will not write a scientific paper on this topic for reasons stated in the blog post, nor will I research deeper in this topic at present. Maybe someone else will who is actually in the field of affective neuroscience – time will tell!

  15. I’ve read Panksepp’s Archaeology of Mind and only studied Barrett in passing, so there’s my bias. That said…

    I appreciate that through language we can propose more finer-tuned coding than without, but the idea that perceiving a sensory experience is dependent on language is befuddling. We know animals can see color; does it matter that they don’t have a word for it? We know they can discriminate scent; does it matter that they don’t think of it as “mom” or “the neighbor dog?” And so if they feel a certain set of physical sensations after being exposed to a set of stimuli, just like a human would, is that not likely to be a similar lived experience to ours just because they don’t have a word for their perception? Why are emotions “special?” And if we are defining “emotions” only as things that must be analyzed using language, and then asserting only humans have them, isn’t that sort of… circular logic? “A doorknob can only be used by animals with opposable thumbs. Therefore, only animals with opposable thumbs can use doorknobs.”

    While I agree that humans are able to fine tune our observations of our experiences with words in a way that other animals cannot, the idea of emotions as a luxury rather than a necessity truly doesn’t fit with an evolutionary perspective.

    These thoughts may be off base without having read Barrett myself, but I’ll throw them out there just to muse!

    1. Katherine, not off base at all – this is my understanding of Barrett’s theory. Not sure it’s circular, though?

    2. I think you missing the underlying point of this scientific theory which looked at ot from the point of the brain. First you assume an organism needs emotions to survive and that we need the world to fill a brain with the realities happening in the world. But the key issue is that the brain is a predictive self organizing system regulating and controling the systems of the body. The movements / actions themselfs are the creators of perception.
      Also see Buzsaki 2019 (the brain from inside out) – or “the free energy principle” by Karl Friston which gives a mathematical statement on bayesian inference – minimize surprise (free energy) by active inference.
      The data itself that the Theory of Constructed emotion is built on is quite solid. Eventhough you explain your view why you perceive the data as valuable. The meta analysis itself is on whether there are brain circuits that show universality to emotion categories; they elaborate though that the brain has many connective options to construct many different instances of say sadness or fear just as a brain constructs the experience of the coulour red (there is no red in nature, our eyes don’t see red, redness is built by the brain using past experiences. -Also see Anil Seth’s works on conciousness.
      Further works by Feldman Barrett on neuronal compression to context building and categorization (many small less connected neurons compressing information to bigger much more connected neurons) ground the actions of the brain to information integration and memory reconstruction (reconstructions of prior experience).
      Categorization is crucial for a brain; it leaves for high probability prediction of needed motor actions plans to fulfill the needs of the body before they arise to minimize free energy (surprise).
      example: cortisol excretion before we get up in the morning so one doesnt faint / or action plan readiness if we roll our ankle, if other action plans weren’t anticipated we would constantly fall over.
      One doesnt need to feel fear to jump out of thr way of a bus; but we sure experience the summery of it – had I not learned the word fear would I even call those feelings an emotion or stick to explaining the affective states themself? (Hot rush in the stomach region, hot flush in face, jittery feeling followed by a “sigh of relief) and how would I verbally categorize that into smaller data / a quick summery which is metabollically econimic…-> sh$%!! That was scary!!

      It is only natural that our brains search for “likeness” in others and the world. That is its predictive nature- Buzsaki states that “to a babies brain nothing is new; it always finds a novel “thing” to be something like ….” so it’s no surprise that if a toddler experiences a dog everything that looks and moves like a dog may be referred to as “dog?” eventhough at that moment the toddler is looking at a sheep.
      I also don’t think thst generally it is appreciated how the brain even learns about the musculoskeletal actions early on in fetal development. There is beautiful work by Khazipoc et al (“early motor activiti drives spindle bursts in the developing somatosensory cortex” / “Early patterns of activity in the developing cortex; focus on the sensory motor system”)
      Buzsakis’, Peuprache & Kubies’ paper on “Emergence of Cognition from action” is another interesting hypothesis.
      So when you see likeness of facial expression they are taught in some form by the musculoskeletal system to the brain. Thats how these thalamu-cortical connections develop.
      Barb Finlay has beautiful papers on developmental stages of brains.
      Science really has to be careful how much we ground to our sensory experiences; it is those that lead us to cognitive biases- which again is economic and a normal way for the brain to minimize free energy. To just stay in the beliefe state we have.
      And yes there are places I traveled to where you really want to supress smiling at people. So the very instances of smiles are categories differently.

      A neuronal system doesn’t rely on the outside world to be activated; it can’t help itself but be active- for if there was no action there’d be no thinking; and its because thinking is happening that there is an “I”.
      Action starts at the chemistry level bound by physical laws and that’s where also a lot of misconception lies. In animal sciences actions are often just thought of a external movements

      From the way I read Feldman Barrett’s work, she also doesn’t say animals don’t have emotions. She states that whether animals have emotions is the wrong question. That it would be much more interesting to ask how a specific animal brain (a mouses brain or elefant brain etc) constructs emotion. What would an emotion constructed by a whale be like that has just started to dive into the depth of the ocean?
      But I guess thsts not as romantic to the general pet owner.

      However I also think that some of the hard core behaviourists take Feldman Barretts work out of context. It suits them to reduce all to action and not to worry about inner states (affective, allostetic thus Interoceptive) I’m unsure how they would explain how a brain regulates the system of its body without Interoception and move about in the environment effectively and economically to survive.
      Personally, I think of the spectrum of mood as a better way to communicate feelings then broad Categorization of a few words that have long lost their honest meaning; but that is down to my upbringing and language categorization- luckily not everything is grounded in english

      1. Thanks for sharing your thoughts on this! I think it boils down to how one defines “emotions” – whether it’s how we choose to name our affective experiences, or the affective experiences themselves.

        Since the book was so full of bad science and cherry-picking, I became very suspicious of any of the scientific statements in the book – and since I’m not a neuroscientist I can’t tell whether for instance the assertion that “the brain is a predictive self organizing system regulating and controlling the systems of the body” is based on more robust data than that extraordinarily crappy meta-analysis. I don’t know if the rest of the field of neuroscience is as incompetent as Barrett seems to be.

        1. Re: ” I don’t know if the rest of the field of neuroscience is as incompetent as Barrett seems to be.”

          “Lisa Feldman Barrett, PhD, is among the top one percent most cited scientists in the world for her revolutionary research in psychology and neuroscience. She is a University Distinguished Professor of Psychology at Northeastern University. She also holds appointments at Harvard Medical School and Massachusetts General Hospital, where she is Chief Science Officer for the Center for Law, Brain & Behavior.’
          Dr. Barrett received a National Institutes of Health Director’s Pioneer Award for her revolutionary research on emotion in the brain. These highly competitive, multimillion dollar awards are given to scientists of exceptional creativity who are expected to transform biomedical and behavioral research. She also received a Guggenheim Fellowship in 2019, the APS Mentor Award for Lifetime Achievement in 2018, and the APA Distinguished Scientific Contribution Award in Psychology in 2021.

          Among her many accomplishments, Dr. Barrett has testified before Congress, presented her research to the FBI, consulted to the National Cancer Institute, appeared on Through The Wormhole with Morgan Freeman and The Today Show with Maria Shriver, and been a featured guest on public television and podcast and radio programs worldwide. She is also an elected fellow of the American Academy of Arts & Sciences and the Royal Society of Canada.”

          1. Astonishing, I know, that someone with those credentials know so little about statistics – or evolution, for that matter! I am deeply concerned about that faulty meta analysis, but I feel like I’m the only one shouting that the emperor is naked.

  16. When I first came across Feldman Barrett’s theory of emotions being constructed, I was immediately taken with it. As someone who did my PhD on judgement bias in dogs and had spent a lot of time watching dogs behave and trying to predict what they would do next, it fit very nicely with how I had come to understand the processing of emotions and the behavioural output as a result. I was dismissive of discrete emotions and focused on affective states. I am still very much focused on affective states. I think because I see so much internal conflict and confusion in both human and animal behaviour. To me, it’s like our brains are in a dark room and we can only make sense of things by gathering information from within and without and connecting the dots with our past experiences. Emotions (or affect, to be consistent with terms) are big signposts for how we should act next.

    However, I also have my roots in behavioural ecology, and the litmus test of does this make evolutionary sense is indeed also central to my thinking. And I cannot imagine how there are not core affects, if you want to reserve the word “emotion” for concepts rather than valence + arousal. There has to be. Animals are born with behavioural strategies they will tend to favour. You can see it in herding breed puppies when they first see sheep at 7 weeks old. That is an extreme example, but what kind of small rodent or lizard is going to survive to adulthood if it’s not inherently fearful of potential predators? This is actually central to my objection to the sport of barn hunt, but that’s a discussion for another day.

    Anyway, I have come to a balance in my mental model of affect and behaviour with a combination. Core affects exist and are the foundations that affective responses to all manner of stimuli and internal processes are built around. And beyond that, affect tracks contingency, so the emotional aspects of learning and conditioning guide our brains in their dark rooms to make sense of the world and arrive at a behavioural response that will hopefully serve us well. Likely started as something inherent, but built on by past experiences.

    I often think of the experiment that showed personality emerging in mice. It appeared to be largely a result of success with various behavioural strategies. You have a natural propensity towards a couple of behavioural strategies, so they are always the first ones you experiment with, and so you will often have success with them seeing as you inherited them and so they must be pretty decent strategies in the first place, and those experiences strengthens those strategies until it practically defines you. Where do those original strategies come from? My behavioural ecology brain says they have to be evolutionarily sensible strategies, and they surely have to include emotional facilitators.

    Thanks for a good read to bring in my new year.

    1. Melissa, thanks for sharing your thoughts on this! I also find the Core Affect Space model extremely useful, and I keep thinking that a lot of the controversy is simply semantic, that it’s about which terms we use for the different parts of the affective/emotional process, all the way from showing innate knee-jerk behavioural strategies to challenges to how the concurring sensations are processed in the cognitive parts of the brain.

  17. I love this article, and will freely admit to also loving the work of both Skinner and Panksepp. As a trainer of tracking and detector dogs, Skinner was on my shoulder, and Panksepp was in the dogs’ core.

    As for CToE, I think it might be better labeled CToF, because feelings (e.g., guilt, shame, jealously, resentment, etc.) seem more likely to be constructed than are emotions (e.g., fear, grief, rage, etc ).

    But that’s just me.

    1. Steve – love what you just said: “Skinner was on my shoulder, and Panksepp was in the dog’s core”…! Such a graphic description! (and might we assume that Pavlov would be on the other shoulder..?)

      1. Of course, Karolina, Pavlov is ALWAYS on the other shoulder . . . as the mediator between Panksepp and Skinner.

        Wise trainers figure out how to harness classical conditioning rather than fight it, because it’s going to happen anyway. After all, it’s not as if Pavlov’s dogs said to themselves, “Hark! I hear yon’ bell. I think I’ll drool now.”

          1. Irith! So glad you liked it! And please call me Karolina… if you were to call out Dr Westlund I wouldn’t even know it were me you were addressing – we Swedes are not very formal!

  18. Hi Karolina. What can I say? I read blogs like this because you brilliant experts continue to expand my brain and educate me. I always want to know that what I am telling clients about why their horses are behaving the way they are and what they are feeling, is as correct as I can be. My understanding has always been about need. Behaviour is driven by a need and that need is wholly attached to emotions. Emotions directly drive behaviour. Panksepp has been my hero in all of this as I totally relate to the brain systems and how they play out within the context of environmental analysis, functional analysis alongside observable behaviours or predictable behaviours. Identifying that need in all of the complexities within the equation ( conditioned or non-conditioned reactions, conditioned or non-conditioned reinforcers, environmental influence, assessing daily management protocols in place et al)

    Thank you for doing what you do.

    1. Melanie – thanks! So glad you found this useful! Great also that you’re pointing out the value of the behaviourist perspective: functional assessments and functional analyses are very useful! We need all the different perspectives!

      1. I don’t think horses are any different to humans, dogs or any other animal- all we want to feel is safe! Safe in where we live and what we face, safe with who we live with and interact with, safe within the rules set by peers/groups/family/office/herd/bonded partners etc, which affect our liberty/ability to have control.
        Control is always interesting. It’s both a conditioned and an unconditioned reinforcer. We humans don’t give horses enough control over their own lives and what we expect them to “do” or face or cope with. No wonder they suffer so under the human innate, hard-driven need to dominate horses as is endemic in the horse industry. Traditional and natural horsemanship techniques are all about our full control via the use of escalating pressure. “We know not what we do” springs to mind.
        Wishing you a very Happy New Year xx

  19. Nicely done Karolina 🙂 I especially like your analysis of the meta-analysis.

    I differ a we bit from you on your point about evolutionary testing. While I agree with Dobzhansky that “nothing in biology makes sense except in light of evolution”, our litmus paper needs to be a bit more nuanced.

    As scientists, as evolutionary biologists, we do look to see whether we need to update our theory of evolution to include new data. e.g. The Central Dogma (DNA is the material of inheritance) was modified to include RNA and transposons and now even epigenetics and prions. What we might, as good evolutionary scientists, do is to test whether the proposed new paradigm makes sense—we can do that in a multitude of ways, including gdanken (which you have done), computer simulations, and empirical tests of data or controlled experiments. There is also no a priori reason to expect that every possible behavior and mutation has occurred and been the target of natural selection—so there may be limits to what natural selection has done in the past. All that said, yeah, there are lots of animals with complex innate behaviors (imprinting is an example that is totally mind-blowing, esp if you have ever been the love-target of an imprinted Gyr or pheasant… lol!).

    Why is “innate” and “localized to a specific brain region” equated?

    just because Darwin didn’t explicitly refer to natural selection or evolution in his treatise on “the Expression of Emotions in Man and Animals” doesn’t mean it doesn’t exist(1). We have discovered many things in evolutionary biology since Darwin. He was seminal, but by no means a god. (2) The Expression of Emotions in Man and Animals”…the title implies a common origin. His whole book is about the similarity between Man and Animals. Anyone who knows evolutionary biology, especially the recently formalized field of phylogenetics, knows that unless there is evidence otherwise, we assume shared traits are due to their presence in a common ancestor…. which implies evolution. And which also implies maintenance through time by natural selection. Darwin had recently been beaten up for implying that man and animals shared common traits and ancestors. He was careful about what he said. But quite frankly, the laws of parsimony suggest that animals do indeed share basic emotions with us. And the more closely related they are, the more strongly we can say that. We might want to approach with some humbleness and not assume identity, since they have indeed evolved independently for a few million years…. But the data suggests we do share a lot of “stuff” (hormones, brain physiology and anatomy, expressions, and even pupil dilation and release of oxytocin when looking at (or smelling?) a “loved one”.

    The radical behaviorists forget that Noam Chomsky annihilated Skinner’s theory of learned language. Humans have a predetermined syntactical structure.

    I do believe the ability to name it has an advantage in a social species. Whether that be in Fisherian runaway selection where we are clearly drawn to a guy who can sing sonnets, or whether is simply allows us to pledge our faith (and parental obligations) to our beloved…. Still, those feelings* of love are important (and we see evidence of it *all the time* on the internet these days) for social bonds and tit-for-tat individual survival—note that we can help a comrade that is down with little cost to us, it benefits us if that comrade then returns the favor. Protecting an injured comrade may not cost anything, and may increase our chance for survival if he reciprocates. I have a youtube video on the evolutionary basis for love—much like this blog, it is NOT a scientific study. Merely a hypothesis. One which I would bet a lot on

    Just good/bad, aroused/depressed does not encompass all the kinds of action that a species needs to perform innately. Highly aroused in a “good” way should not always result in mating behavior, sometimes it should involve patting your teammate on the back or doing a fist bump!

    AGREE wholeheartedly to your last comment: “To me, the Constructed Theory of Emotions is about how we think about our emotions, and how we classify them. Not what triggers them, and how we respond to them – which behaviours we show, or what the outcome of those behaviours are; how they were once (and perhaps still?) adaptive.”

    1. Thanks for your thoughts, Caitlin! You make an important point of how being granular in expressing emotions may indeed be adaptive!

      The “innate” being equal to “localized” is my understanding of Barrett’s take on this; only she doesn’t typically use the term “innate” but rather “classical”. And that’s one of the problems I have with her book: that nobody is actually arguing what she’s debating against. It’s a straw man.

  20. Thank you Karolina,
    Just reading your blog and the comments that followed gives me hope for the future.
    Give yourself a pat on the back for taking the time to write this blog (and finish reading the book). It takes courage to go against one of the most cited scientists in the world. And you have done it convincingly! I hope this blog will be read and spread widely and open the door for discussion and conversations

  21. I had never heard of Constructionist Theory of Behavior before and after reading this article, I wasn’t sure I really understood it (I’ve not read the book). So I did some additional research. Unfortunately, I came away with few “answers”. Research is still “mixed” (for example, I found studies indicating that by 6 months of age, infants are able to determine “basic” emotions based on facial expression; then I found evidence that facial expression of emotion is individual and humans are terrible at recognizing emotions based on facial expressions). I found fMRI and PET studies that indicate a single, specific area of the brain being indicative of a specific emotion; other studies that said “not so fast; there is more of a “generalized” area of the brain responsible for emotion”; evolution certain favors the idea of “hardwired” basic emotions but others say that theory is poppycock. So who knows? I certainly don’t. BUT, it seems to me that CTOE (whether correct or incorrect) can be dangerous. If we view animals as being only able to feel “affect” (pleasant to unpleasant and calm to excited), this gives us more latitude to disregard how we treat them. It lessens their sentience, it lessens their suffering when we expose them to fear-provoking stimuli. It means animals can’t feel specific emotions, just some jumble of physiological responses to stimuli that they can make no sense of. It means we can have free reign to treat animals more like unfeeling automatons, rather than intelligent, feeling, sentient beings. For this reason, I don’t really care which is “correct”. I’ll be sticking with the idea that animals DO feel emotions (and can make sense of them), that they can suffer when experiencing fear and other negative emotion, that they can (and do) grieve. I certainly believe some fears CAN be learned, but perhaps based on hardwired emotions. For example, my father was in the military and serving overseas when I was born. Thus, I was born in Germany (not the U.S.). When my family was coming back to the states, I had to get a series of shots to enter the country. I was maybe 3 years old (and have no memory of this, but I certainly heard the story enough times!!). The doctor who gave me the shots wore a white coat. For many years, whenever I saw someone (man or woman) wearing a white coat, I’d cry and run away from that person. Obviously, there was classical conditioning going on there (people wearing white coats = shots = PAIN!). But it seems as if my wanting to avoid PAIN is something I didn’t have to learn but is “hardwired”.

    1. Jan, such an important point you’re making, and one I’ll have to add for when I revise this post at some point: what does following the CToE imply for our treatment of animals?!

  22. What am amazing read(!!). I thoroughly enjoyed it, and eagerly finished reading. I cannot say the same thing about CToE or most of LFB work . I know it’s not so scientific to say that it’s highly triggering, and things in your gut scream “this isn’t correct!”. Call me an “anthropomorphizer”, I’ll wear that badge proudly. I’ll stick in my tiny corner of believing animals have core emotions (hard to survive without!) and rich emotional lives.

    Imposter syndrome is real, especially when it comes to questioning someone of LFB status, but he works always seem to be so condescending that I can’t read anymore, I developed serious aversion years ago.

    Thanks sooo much for the time you took for
    this blog. Much respect to you.

        1. Typically the very first comment needs to be moderated before appearing publicly, and I’ve perhaps been a bit slow on the ball these last couple of days. But at present there are no pending comments, so can’t explain it… Sometimes simply reloading the page / the browser or restarting may resolve the issue.

          1. Reading the comments here I am not surprised to find most in agreement with the author since this is a blog and not a more widely circulated essay. And while some of the commenters have indicated that they have read or attempted to read LFB’s book it is also unsurprising that readers of this blog, like its author, might reject the theory of constructed emotion in favor of some combination of outdated theories (including folk psychology or pop-psych), and may generally be confused about the difference between feelings and emotions.
            I will further note that very few comments include references to any specific research on emotion and the brain and I will in this comment try to balance the scales a bit.

            Let’s start with Paul Ekland’s theory of Basic Emotions.
            Paul Ekman’s theory of universal emotions also referred to as the Basic Emotion Theory (BET), has dominated psychology for more than 50 years: the idea that certain emotions are universal, innate, and hardwired into our brains. But it has been called into question by numerous researchers in recent years. I do not believe that we need to spend a great deal of time examining this theory. It has been taught at universities and has trickled down into folk psychology. Ekman’s research explains that one can infer emotional states from expressions on faces and that emotions are universal, innate, and hardwired into our brains.

            Over the last two decades, however, researchers began raising questions about Ekman’s methodologies. Ortony and Turner stated in their 1990 paper that it was “an article of faith rather than an empirically or theoretically defensible basis for the conduct of emotion research:”

            https://psycnet.apa.org/record/1990-27526-001

            In 1994, James Russell was one of the first to challenge Ekman’s theory, saying, “Facial expressions and emotion labels are probably associated, but the association may vary with culture and is loose enough to be consistent with various alternative accounts.”

            https://psycnet.apa.org/doiLanding?doi=10.1037%2F0033-2909.115.1.102

            By 2003, Russell introduced the concept of “core affect,” a sort of ‘minimal universality” or innate, shared emotional base. In this paper Russell “laid out a new vision for the intricate ways that nature and nurture interact to produce the familiar yet enigmatic states we know as our emotions.”
            https://pubmed.ncbi.nlm.nih.gov/12529060/

            Perhaps the most important challenge to BET comes from Carlos Crivelli and Jarillo de la Torre. who attempted to replicate Ekman’s findings.in ways that would eliminate Western biases :

            https://psycnet.apa.org/record/2016-19236-001

            “Crivelli’s team conducted several studies (three published so far, and another under preparation) that cast serious doubts on the Universality Thesis.”

            This brings us to Diversity Theory

            An alternative to BET is now being referred to as “The Diversity Thesis.” While it is still young and controversial, evidence supporting it’s claims is fast growing. This formidable opposition to the Basic Emotion view has emerged in recent years, spearheaded by Lisa Feldman Barrett, a professor of psychology at Northeastern University in Boston, and her disciples.”

            https://en.wikipedia.org/wiki/Theory_of_constructed_emotion

            https://lisafeldmanbarrett.com/books/how-emotions-are-made/

            “Our findings indicate that perceptions of emotion are not universal, but depend on cultural and conceptual contexts.”

            https://pubmed.ncbi.nlm.nih.gov/24708506/

            “The cues that perceivers anchor on, and the types of inferences that perceivers make appear to depend on cultural context. These new findings challenge the conclusions of some of the most widely accepted emotion experiments, including the conclusion that there is strong cross-cultural consistency in emotion perception.”

            https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5624526/

            “In a 2018 study, a team of cultural psychologists, including Michael Boiger and Batja Mesquita at the University of Leuven, sampled shame experiences from hundreds of American, Japanese and Belgian subjects.”

            https://pubmed.ncbi.nlm.nih.gov/29389207/

            I will add this final bit of research in support of my claim. “Qi Wang, a professor of human development at Cornell University in New York, has observed that, when European American parents share memories with their kids, they tend to put the focus on the child’s own feelings and unique role in the situation. East-Asian American parents, by contrast, prefer to emphasize their children’s relatedness to others.”

            https://journals.sagepub.com/doi/10.1177/1750698016645238

            I believe we can conclude that there is growing evidence that culture and language play a role not only in the construction of emotions but in how they are perceived.

            Additionally, one aspect of LFB’s research that is not addressed here is that of the predictive brain so I add this final piece of research.

          2. Thanks for adding this historical perspective, Theodore! It seems completely reasonable to me that the answer is in the synthesis of Nature AND Nurture, not one or the other! 🙂

  23. From one ethologist to another, thank you SO MUCH for writing this blog. It is so thoughtful, so thorough, so measured and humble, and so well substantiated. It may evolve, like all things do and should, but it’s a perfect piece for this moment in the field of animal behavior, one increasingly drowning in the god-like centrality of “nurture” over “nature” in the sleepy illusion of separation we experience in the 21st century. I hope it succeeds and survives. It surely “fits”.

    This book (which I doubt I’ll actually read because it sounds so painful, so I’ll refer to the sentiment described here by this article on it) is so representative of the human-centric, separatist, far fetched modern assertions in the name of data-driven “science” that sadly plague our “information age” (misinformation age) with useless ponderings divorced from the most widely established natural laws, misleading us down empty rabbit holes.

    Barrett, as too many other modern scientists, tries to reinvent a wheel (and a square one at that), consistent with her concept that all of life is simply one “Groundhog Day” after another, where only the proximate “nurture” exists and “nature” has nothing to bring to the table from ultimate lessons learned.

    Hogwash.

    Serendipitous timing for my read of your piece. We’ve had a COVID Christmas and are basically hibernating at home. There’s been a space in my life and therefore mind in the past few days for NEW research, questions, observations, thoughts, information to germinate for the first time in months. I’ve been reconsidering just how insane humanity currently is on so many levels, how far up our own asses we are these days as a species such that we don’t even know (remember) that life as most of us know it (entirely temporarily insulated from nature’s laws) is NEW. What we think of as “the world” and “life” is actually just an evolutionary event that’s arisen in about a century.

    As an applied ethologist, I spend much of my time appreciating just how wrong things go when humans interfere with or perceive themselves as apart from nature. I spend a lot of time in absolute wonderment of nature’s principles, systems, phenomenon, solutions to problems. And a lot of my time marveling at humanity’s superiority complex and stupidity.

    So then I get to read your article. Great timing. Another demonstration of our erroneous common modern human tendency towards elitist, reductionist, naively insulated perspectives of our world that are entirely divorced from context of natural history and life, evolution, the real pressures of threats and opportunities, the reality of life unbuffered by our modern comforts that *seem* to have effectively created a human world separate and protected from the “wilderness” of life. We’ve lost all sight of context. We left it on the shore of history for a new fantasy voyage and believe we are in a new world. But we’re not.

    It is a fragile, and I fear short-lived, illusion we are all living in, as we have chosen the bliss of ignorance regarding our intrinsic connections to the rest of nature. We have chosen a dream for its apparent promise of ease, and we’re running out of nighttime hours before we wake. We are not gods. We are not islands. We are simply organisms, like all of the other organisms, who can’t seem to remember what we have forgotten. A truth that most other organisms still cannot afford to forget- that emotions are a necessary adaptation for many, arguably most, forms of life- words that simply symbolize the underlying evolutionary purposes they serve.

    A certain sector of science continues (and likely always will) to insist that humanity somehow exists above nature in a world defined entirely as ours with nature as our backdrop and playground. Modern conveniences and medicine have increasingly prevented our ignorance from being quickly apparent or selected against, and we’re relatively quite “comfortable” (many of us) with the easy living we’re currently making.

    We might confess we feel “off” these days, blame family or work or current events, describing our symptoms of severance from nature as pathology. We feel it vaguely nagging at us from deep within (in our chronic loneliness, anxiety, frustration, depression), but we call it a “disorder” and give it pills. It’s a strange dream we’re all living in together, where we’re the stars of our own strange movies living in a world of conditions that DID NOT EXIST UNTIL THE LAST 120 YEARS.

    We forget, every day, that we’re living in a sci-fi world. A strange new world that’s like nothing the world has ever been before.

    An important tangent. Electricity was invented in 1901. What is our modern world if not electricity? Cars, phones, computers, elevators, planes, internet, social media, you name it. It’s not that life before all of this was free of human arrogance. Far from it. It was a harsh and humbling (but also likely more intuitive) reality that we were living until very recent years.

    Our innovations have built beautiful, incredible things in this world. But those things are fragile, and largely illusions that will catch up with us. Nature is already answering, checking and balancing. We’d be wise to remember the “nature” part right about now in the world, and step down from our foolish pedestals on which we play puppeteer to the world.

    We didn’t construct emotions anymore than we invented perception. We continue to minimalize nature so that we can continue to exploit it without cognitive dissonance. Simply, we need to continue to view LIFE and it’s processes through the lens of our narcissistic human narrative.

    After all, where would the world be without us?

    We just might get the chance to find out.

    As defeatist as that may sound, I’m actually entirely inspired. Knowing that others continue to challenge the insanity of culturally accepted erroneous “information” gives me so much hope. I personally don’t want to be asleep. I want to feel life deeply, know it, connect with it, understand it, share it with others. It is the only place in which I am not lost. Here, in this truth. Thanks for meeting me here. Thanks to anyone who shows up here.

    1. Kim!

      You’re a poet, too!

      I only knew you as a fellow ethologist across the pond, but I’m sitting here smiling. Thank you. So glad you liked the post.

      You touch on many important topics, what stands out to me is that obviously the nature-nurture conflict is still alive and well; that data-driven science can actually be put in quotation marks, believing we’re in a new world while we’re really not, nature being a backdrop rather than something we’re immersed in, and perhaps the most powerful statement in this context, for me, was that the “words simply symbolize the underlying evolutionary purposes that they serve”.

      Thank you for sharing your thoughts! 🙂

  24. Thank you Karolina. Earlier this year I was battling my way through this book. I had to back track continously, but I had the same thing all the time! In my mind, saying…”But what about Panksepp’s very sound research? But so and so”. Long time wanting to discuss this with some peers, but just not getting there, hoping to finish the book first. I was very surprised by a lot of her very matter of factly statements. I was trying to unify/intergrate her theory with what she calls the classical view. Trying very hard to take statements seriously and trying to find a way to better understand humans and off course dogs. So I kept going, using pure grit to get through the book, but eventually I dropped it …up to now. I think you nailed it. Yes, your blog was indeed a long read, but by far not that aversive than getting through the book. I think it is so difficult to make sence of it for me, because some of the things she claims and states sort of makes sence too (like language describing a “constructed emotion”about when you have the empty chips package ;-)), so I tend to give people the benefit of the doubt, and try and adjust my view, how else do we get better in understanding the world? Anyway, good read, thank you and let’s start discussing this!

    By the way, dogs also do this showing of the teeth as a way to show benign intent, or so it seems when they play for instance. One tends to see a lot of teeth, way back to the last molars. It’s almos like they say, “You have nothing to fear from me. See no hidden weapons. See them all”.

    1. Thanks Suzanne! It’s interesting how hard it is to read something that challenges core beliefs, isn’t it..?

      Hmm… I’m really lousy at reading dogs, but don’t they also have a toothy grin that’s more of a warning/high negative arousal? In what way is it different? In primates there’s a silent-bared teeth (friendly) and a vocalized-bared teeth (typically fear/arousal related).

  25. Thanks so much for sharing your thoughts on this Karolina. I too have had this book on my shelf for a couple of years, having purchased it as a core book for a study on canine behaviour – it got put back on the shelf after reading the first few pages and dipping in randomly to see if it got any better! I made the point in the study submission that the CTofE perhaps links to the tertiary level of emotional processing, but it was a struggle to complete the submission as I had such an averse reaction to the content of the book – as you highlight, triggering emotions on every page (or para.)! It was great to read your thoughts on the evolutionary function, and thank you for bringing Jaak Panskepp back into the conversation. Wishing you a very happy New Year.

    1. Thanks for sharing your thoughts Julie – it’s a relief to realize I wasn’t alone in this! Happy New Year!

  26. Thank you! This made me laugh mi arse off: ‘Smiling was invented in the Middle Ages and broad toothy-mouthed smiles… became popular only in the eighteenth century as dentistry became more accessible and affordable. ‘

    Precious, just precious xD

    1. I know. It’s on page 53, and that’s actually one of the reasons I stopped reading the first time around, and why I had such trouble believing that any of the other statements rested on solid science.

  27. Thanks Karolina; that was a great read! I am glad you took the trouble to write it. I tried recently to engage LFB in a friendly discussion of some of the core issues but she side-stepped me every time (three).

    1. Mark – so glad to hear that you enjoyed it! It’s too bad the discussion climate is so infected. The comments I’m getting is that people get really triggered by her ideas, so I suspect that she has met a lot of confrontation over the years. That might explain why she’s not in a place to have that discussion, perhaps.

  28. Thank you for this! As someone makes their living trying to help horses who are doing things humans don’t want them to do, I constantly come up against this. What I am sure about is that not acknowledging emotions compromises welfare. Love Gay Bradshaw’s work on trans-species psychology; and very very glad to see this ‘proof’ picked apart. Not sure I could have read it, and quite sure I couldn’t have come up with such coherent analysis of it.

    1. Glad you enjoyed it, Felicity! That trans-species psychology sounds really interesting, will have to check it out! 🙂

  29. The author of the book you are critiquing is just one more wonderful example of the blinding arrogance shown by many humans toward other animal species on the planet – not to mention the almost total disruption to natural plant communities.

    Great post. Like you with the book, I couldn’t read it all because the constructionist idea is so off-base.

    My first question would be, does this person interact daily with animals outside lab cages. Does she train any animals does she have pets?

    Many people don’t understand evolution. All the features of all species alive today have been honed from the same material but in a complex array of niches.

    The idea that animals (of which we are one kind) don’t have innate emotions similar to ours is utterly ridiculous.

    I’ve just rescued my son’s dog from a boarding kennel where she evidently chewed into the partical board door of the pen she was put into one night. Looking into a room full of dogs near the entrance, one could see every emotion ranging from hope when they saw the leash in my hand to one dog that looked catatonic. Most were just perplexed.

    1. Hertha, she actually does discuss the value of seeing emotions in animals (accepting the mental inference fallacy) as a way that leads to more empathy. But she then intentionally puts on her research hat. I’m sure she takes it off when she steps out of the office..! Don’t know if she has animals!

  30. Hi Karolina,

    I didn´t read that book (and I am pretty sure that I won´t in the future).
    Question: Could her >findings< influence how humans will treat animals in future? If no: ignore her. If yes: dangerous (I don´t think that many politicians believe that animals might have emotions, as horrible livestock husbandry is allowed and usual). Kind regards Carola

    1. Carola, great point, and one I will have to cover when I revise this post at some point! I suspect that it will influence how people treat animals – Barrett even says so herself! “Frankly, if everyone engaged in the mental inference fallacy with animals, and in the process we admitted those animals into our moral circle, maybe we’d have fewer poachers who slaughter elephants and rhinos for their ivory or hunt gorillas or bonobos as food” (p 278). To that I would add that we would completely rethink how we interact with all animals, whether they’re zoo animals, farm animals, pets or laboratory animals.

  31. Thank you for this! I also read this book a few years ago and found it very doubtful and contrary. It just didn’t make any sense to me especially after reading much of Panksepp’s work and generally animal behavior and welfare work. Great to see this thorough critique of it.

  32. I absolutely agree with the points you raise here. I was especially interested because I have just read a more recent, unconvincing book by the same author, whose style I, too, find patronising.
    Quite apart from the logical criticisms you make from an evolutionary perspective, one can’t help but wonder whether Barrett has ever actually known an animal.

    1. One thing that concerns me about the present state of human evolution is the tendency of humans to pull away from the natural world, to assume that we are somehow not animals (and for goodness sake, never predators!). Whether we also have existence in other parts of the universe or not, at present we find ourselves here, as animals, embedded and embodied in this particular material Earth. To withdraw into fantasies of ‘reality’ that take no account of being here, and having to survive here in this system, is to my mind self-destructive to the point of human extinction. I hope that trend in thinking does not wipe us all out. We are here, we are animals, we do have kinship with other creatures here, and if we are to survive as a species, we need to accept that. It’s not about ‘saving the Earth’; it’s about not going extinct.

      1. Yes, absolutely. In using the word ‘animal’ I meant, of course, non-human animal. If we, as animals, feel a range of emotions then, obviously, so do other species.

        1. I wasn’t pointing that at you, Sandy. It’s just something I’m concerned about. That whole rant belonged in a stand-alone reply to the blog post. — I was delighted to discover The Hidden Spring this year, and set out on quite a reading spree among Solms’ work and that of Panksepp — all of that has helped me feel a stronger kinship with the creatures that live near me, including my feral cats. (I live in a semi-wilderness in western Ireland.) — So yes, has that author ever met a non-human animal? I do wonder.

  33. Thank you for this piece! I have heard Feldman cited as if definitive when I know others question her conclusions.
    Emotions seem to be such a difficult issue for behaviorists. I often hear it discussed as being a private event of another that we cannot “know.” But we are social beings. Those who have difficulty “reading” others emotions have difficulty in our society. Our social interactions seems to assume that on a day to day basis we maneuver our actions with our spontaneous assessment of the emotions of those around us.

    As for smiles- the fact that blind people smile seems proof to me that it is not a learned behavior. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5902524/ Which states:
    “Seventeen studies provided evidence that blind and sighted spontaneously produce the same pattern of facial expressions, even if some variations can be found, reflecting facial and body movements specific to blindness or differences in intensity and control of emotions in some specific contexts. This suggests that lack of visual experience seems to not have a major impact when this behavior is generated spontaneously in real emotional contexts“

  34. I too love Brandon Sanderson, even though he writes tomes.

    One thing missing, except during your end notes; nowhere in here is it mentioned that there is strong link between hormones and emotions. I am in adrenal exhaustion, proven beyond a doubt when confronted with a bear, and had no fear response.

    1. Jacki – oh Sanderson is fabulous! I’m eagerly awaiting any screen adaptations!

      Yes exactly, there’s no discussion about hormones (as I recall) in the book.

        1. As far as I know, he’s aiming for Mistborn to be a film, but Stormlight Archives a series! 🙂
