Can cognitive methods be used to study the unique aspect of emotion: An appraisal theorist's answer

I address the questions of whether cognitive methods are suited to the study of emotion, and whether they are suited to the study of the unique aspect of emotion. Based on a definition of cognitive processes as those that mediate between variable input-output relations by means of representations, and the observation that the relation between stimuli and emotions is often variable, I argue that cognition is often involved in emotion and that cognitive methods are suited to study them. I further propose that the unique feature of emotion has to do with the content of the representations involved in the transition from stimulus input to emotion. Emotions are elicited when stimuli contain information about the satisfaction status of goals (i. e., when they are goal relevant). Given that cognitive methods are fit to study any representation-mediated process regardless of their content, they can a fortiori be used to study a process that operates on representations with goal-relevant content. I compare this process to processes that have no or a different relation to goals, including the process that deals with purely valenced information.
