The notion that schizophrenia patients' subjective experience of emotion might not match their facial expressions is not new. Indeed, early theorists, including Sullivan and Bleuler, among others, commented on an apparent discrepancy between what schizophrenia patients reported feeling and what they outwardly expressed to others. Moreover, family members have noted that their ill relatives often report experiencing strong emotions. For example, Bouricius (1989) presented samples of her son's diary writings, which articulated the experience of clear and complex emotions. Nonetheless, psychological research into the emotional features of schizophrenia has lagged behind the astute observations of the early theorists and family members.

In this chapter, we will concentrate on one aspect of the subjective experience of schizophrenia, namely the subjective experience of emotion. In our view, which is shared by a number of psychological researchers, emotions are complex, multichannel systems that have developed through the course of human evolutionary history to help us deal with problems, challenges, and other events and stimuli in our environment.
