Explain the event-appraisal-emotion sequence. Discuss how it might be used to regulate ongoing expression.

          The event-appraisal-emotion sequence begins with the occurrence of an emotion-inducing stimulus and ends with the unfolding of the various components of emotion (Deckers, 2010). There are four common assumptions derived by Roseman and Smith as related to the appraisal of emotion-inducing events. The first assumption is that different appraisals of the same event produce different emotions (Deckers, 2010). The second assumption is that the same appraisal of different events produces the same emotion (Deckers, 2010). The third assumption is that the outcome of the appraisal process elicits the involuntary unfolding of emotion (Deckers, 2010). The last assumption is that appraisal can occur above and below the cognitive awareness of an individual (Deckers, 2010). Therefore, appraisal occurs in steps. First, emotion-inducing situations create stimulus for emotion. Then the pre-aware appraisal determines the positive and negative valence of the stimulus. Then the appraisal process comes into an individual's awareness, and then it undergoes cortical evaluation that conforms the perception of the stimulus to the personal attitudes, schemas, personality, goals, and needs of an individual (Deckers, 2010). Emotion also unfolds in an forms of behavior, affect, expression, and physiological response (Deckers, 2010). The event-appraisal-emotion sequence might be used to regulate ongoing expression  by displaying the process of how events influence which emotion an individual has, when he or she has them, and how he or she experiences and expresses emotion.
