Flat affect in schizophrenia does not reflect diminished subjective experience of emotion.

Abstract

Although accorded historical significance, affective features of schizophrenia have only begun to receive systematic empirical attention. Interestingly, both early psychopathology writers and more recent investigators have reported frequent discrepancies between schizophrenics' feelings and outward expressions of emotion. Using a more comprehensive assessment of emotion, the present study examines the relationship between emotional experience and expression in a sample of medication-free schizophrenics. Compared with their normal counterparts, schizophrenics were indeed much less facially expressive of both positive and negative emotions during emotion-eliciting films, yet they reported experiencing as much positive and negative emotion. Therefore, the blunted affect typical of some schizophrenics misrepresents their underlying emotional experience. Future research into an inhibition hypothesis is recommended.
