Integrated Models of Cognitive Systems

Research in psychology and neuroscience shows that complex interactions exist between cognitive and affective processes. Although it is clear that emotions influence cognitive processes, the mechanisms of these interactions have yet to be elucidated. This chapter describes a model of a generic mechanism mediating the affective influences on cognition, implemented within a domain-independent cognitive-affective architecture (MAMID). The proposed mechanism is based on the hypothesis that emotions influence cognition by modifying the speed and capacity of fundamental cognitive processes (such as attention and working memory) and by inducing specific content biases (for example, threat or self-bias). This hypothesis is realized within MAMID by modeling emotion effects in terms of parameters that control these architecture processes. While MAMID includes a model of cognitive appraisal, the primary emphasis is on modeling the effects of emotions and affective personality traits on the processes mediating situation assessment and decision making, including the processes mediating cognitive appraisal. Initial evaluation experiments demonstrated MAMID's ability to model distinct patterns of decision making and behavior associated with different emotions and affective personality profiles.

Keywords:   MAMID, emotions, cognitive processes, cognition, attention, working memory, self-bias, cognitive appraisal, affective personality traits, decision making
