Episode notes

It's really more complicated than the idea that you have a fear circuit in your lizard brain that gets triggered and then poof, you're fearful. The brain actually starts to prepare your body to support whatever action your brain is believing that it should take. So when your brain conjures past experience to make sense of sense data, it's constructing a concept. And if the sense data match the prediction, then the response just executes.

Emotions are at the same time utterly central to who we are — where would we be without them? — and also seemingly peripheral to the “real” work our brains do, understanding the world and acting within it. Why do we have emotions, anyway? Are they hardwired into the brain? Lisa Feldman Barrett is one of the world’s leading experts in the psychology of emotions, and she emphasizes that they are more constructed and less hard-wired than you might think. How we feel and express emotions can vary from culture to culture or even person to person. It’s better to think of emotions of a link between affective response and our behaviors.
