Emotions are a bit of a minefield when you run a science podcast. Emotions are constant for human beings so everyone knows what they are and can talk about their emotions all day but scientists have very precise ways to discuss emotions. This means you end up talking a lot about terms and techniques that seem to just be making an everyday thing needlessly complex. In this episode, we do a bit of myth-busting and talk about what all the terms from emotion and mood through to valence and affect mean. We also talk about how our guest studies emotion data from a sleep deprivation lab and the surprising findings we find what shows how we act and think doesn’t always match how we feel or say we feel.
