Scientific discourse has drifted to other meanings and there is no consensus on a definition . Emotion is often intertwined with mood, temperament, personality, disposition, and motivation . In some theories, cognition is an important aspect of emotion . Those acting primarily on the emotions they are feeling may seem as if they are not thinking, but mental processes are still essential, particularly in the interpretation of events . For example, the realization of our believing that we are in a dangerous situation and the subsequent arousal of our body's nervous system (rapid heartbeat and breathing, sweating, muscle tension) is integral to the experience of our feeling afraid . Other theories, however, claim that emotion is separate from and can precede cognition . </P> <P> Emotions are complex . According to some theories, they are states of feeling that result in physical and psychological changes that influence our behavior . The physiology of emotion is closely linked to arousal of the nervous system with various states and strengths of arousal relating, apparently, to particular emotions . Emotion is also linked to behavioral tendency . Extroverted people are more likely to be social and express their emotions, while introverted people are more likely to be more socially withdrawn and conceal their emotions . Emotion is often the driving force behind motivation, positive or negative . According to other theories, emotions are not causal forces but simply syndromes of components, which might include motivation, feeling, behavior, and physiological changes, but no one of these components is the emotion . Nor is the emotion an entity that causes these components . </P>
