摘要:
The present study investigated flat affect in schizophrenia within a multicomponent model of emotions in which affects were identified with the expression or display of feelings. Display, as well as other components of emotion, such as subjective experience and psychophysiological reactivity, were examined as 24 schizophrenic inpatients (12 with flat affect) and 12 depressed inpatients were guided through imagery of personal emotional experiences. It was hypothesized that display variables would show a relationship with flat affect, whereas physiological and subjective variables would not. Increased flatness of affect was associated with longer pauses and reduced dyadic interaction and less zygomatic (cheek) electromyogram activity. The flat affect patients unexpectedly showed more corrugator (brow) electromyogram activity compared with the depressed group, which perhaps reflects difficulty in self-expression. The flat affect group had faster heart rates at baseline. The groups did not, however, differ in self-report of the intensity of experienced emotion. These results support the view that flat affect patients show a reduction in emotional display, whereas other subsystems of emotion processing appear normally engaged.
