I n this chapter I suggest that affect plays no essential role in identifying familiar persons. Affective response to familiars is better thought of as a consequence than a cause of identication. Although affect does not play an essential role in identication or misidentication at the subpersonal level, atypical affective experience is important to the formation and maintenance of beliefs. I discuss the relevance of these ideas to the cognitive explanation of the Capgras delusion.
