Emotion Emotion Though emotions comprise a significant and crucial part of our individual and social experience, emotion is an elusive concept, difficult to define and measure. Through scientific research psychologists have learned much about nature of emotions, but some interesting and important questions remain unanswered .

The Opponent-Process Principle of Emotions After sympathetic nervous system activity slows down, the body responds with increased parasympathetic activity Removal of a stimulus that excites one emotion causes a swing to an opposite emotion.
