Radical Theory Overturns Old Model of How Emotions are Made

In her new book, professor of psychology Lisa Feldman Barrett proposes a radical new theory of emotions.

The classic model of emotion goes something like: You're born with an innate suite of emotions – happiness, sadness, anger, fear. You feel these emotions by perceiving a stimulus. That triggers a circuit in your brain. That then causes a bodily response, which causes you to behave a certain way.

Emotions happen to you, essentially. 

That’s all wrong, says Lisa Feldman Barrett, an author and psychology professor at Northeastern University. In her latest book, "How Emotions Are Made," Barrett synthesizes research from neuroscience, biology and anthropology to construct a radical new theory of emotion. 

According to Barrett, emotions aren’t reactions to the world. Rather, emotions actually construct our world. And it happens because of interoception.

Interoception is our sense of the physiological condition of our bodies. This sense monitors our internal processes and sends status updates to the brain. Those updates come in four rudimentary signals: pleasantness, unpleasantness, arousal and calmness. Emotions, Barrett claims, are formed from the brain's attempt to make sense out of this raw data. The brain does this by taking the raw data and filtering it through our past experiences – through our learned concepts.

(From a study that asked participants to interpret emotions by viewing facial expressions.)

This means emotions aren't objective reflections about events in the world. Barrett elaborated in a recent episode of NPR's Invisibilia podcast:

“For every emotion category that we have in the U.S. that we think is biologically basic and universal, there's at least one culture in the world that doesn't really possess a concept for that emotion and where people don't really feel that emotion.”

The same concept applies to vision, Barrett suggests, noting cases in which blind people who've had corneal damage since birth remained blind for some time after receiving transplants.

“They don't see for days and sometimes weeks. And sometimes years there are things they can't see because they don't have concepts. Their brain has no past visual experience to make meaning of the visual sensations that they receive.

...We would imagine from the classical view that they would just be able to see everything, but they don't.

The key implication of Barrett's theory is both striking and somewhat liberating: We have a lot more control and responsibility over our emotions than previously thought. The concepts we've accrued, whether consciously or not, can be learned and unlearned. According to the theory, you have the power to fundamentally change your experience of emotion.

Barrett's theory has a catch, though. If Barrett is correct, then what should society tell those suffering from, say, PTSD? To sit down and learn some new concepts? Barrett said: 

“I see the risk in what I'm saying – right? – but science is science. And we have to - I feel like it's necessary to draw people's attention to what the science has to say. And in the proper context in society, in culture, people can debate the consequences. But I think, you know, I do think that it's very dangerous to treat things as objective when they're not.”

Four philosophers who realized they were completely wrong about things

Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?

Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.

What should schools teach? Now is the moment to ask.

The future of learning will be different, and now is the time to lay the groundwork.

What should schools teach? Now is the moment to ask. | Caroline ...
Future of Learning
  • The coronavirus pandemic has left many at an interesting crossroads in terms of mapping out the future of their respective fields and industries. For schools, that may mean a total shift not only in how educators teach, but what they teach.
  • One important strategy moving forward, thought leader Caroline Hill says, is to push back against the idea that getting ahead is more important than getting along. "The opportunity that education has in this moment to really push students and think about what is the right way to live, how do we do it and how do we do it in a way that doesn't hurt or rob the dignity of other people?"
  • Hill also argues that now is the time for bigger swings and for removing the barriers that limit education. The online space is boundary free and provides educators with new opportunities to connect with students around the world.
