How Many Different Kinds of Emotion are There? ·

How Many Different Kinds of Emotion are There? · | Sciences & Santé | Scoop.it
Throughout life, our feelings influence the choices that we make. We watch TV shows that make us laugh or cry. We avoid people that scare us. We eat until we feel satisfied. Even though these emotional feelings determine how we behave, psychologists have not resolved how many different kinds of emotions we feel. One theory is that we feel five or six different categories of emotion, like anger and amusement, each completely distinct from all of the others. Another theory is that we feel two dimensions, like pleasure or displeasure and excitement or calmness, that are mixed together to form all of our emotional feelings. To study the number of different kinds of emotional feelings that people reliably report experiencing in response to different situations, we collected over 300,000 self-reported emotional responses to 2185 emotional videos. We then introduced mathematical techniques to see how many different dimensions of emotion were captured in people’s responses. Our findings indicate that there are at least 27 different kinds of emotion, and that many of them can be mixed together. To show what these different emotions are and how they can be blended together, we created an online interactive map. The map reveals that the structure of the emotions that people report experiencing is richer and more complex than scientists had thought. Our results have many important implications, influencing how people study emotional disorders, the way the brain represents emotion, and ways to design machines that react appropriately to the emotions we express.
