Research by neuroscientist Matthew Lieberman found that labelling an emotion, putting a precise name to what you are feeling, reduces its intensity. This is called affect labelling. When you name a feeling, you activate the prefrontal cortex, the part of the brain associated with reasoning and regulation, and reduce activation in the amygdala, the part associated with fear and reactive response. The act of naming literally changes the chemistry. Most people work with a very small emotional vocabulary: happy, sad, angry, stressed. This is like navigating a complex landscape with a map that only shows three or four features. The territory is much richer than the map. There is a significant difference between feeling frustrated and feeling humiliated, even though both might show up as anger. There is a significant difference between feeling anxious and feeling ashamed, even though both might show up as withdrawal. The word you use matters because it determines what you understand the emotion to be pointing at. Developing emotional vocabulary is not a soft exercise. It is a precision tool. The more accurately you can name what you are feeling, the more accurately you can understand what the feeling is about, and the more options you have for responding to it. Vague emotion produces vague understanding which produces reactive responses. Precise emotion produces precise understanding which makes intelligent responses possible.
