Appraisal theories of emotion are theories that state that emotions result from people's interpretations and explanations of their circumstances even in the absence of physiological arousal (Aronson, 2005). There are two basic approaches; the structural approach and process model. These models both provide an explanation for the appraisal of emotions and explain in different ways how emotions can develop. In the absence of physiological arousal we decide how to feel about a situation after we have interpreted and explained the phenomena. Thus the sequence of events is as follows: event, thinking, and simultaneous events of arousal and emotion. Social psychologists have used this theory to explain and predict coping mechanisms and people's patterns of emotionality. By contrast, for example, personality psychology studies emotions as a function of a person's personality, and thus does not take into account the person's appraisal, or cognitive response, to a situation.
