Emotional expression and feeling in schizophrenia: effects of specific expressive behaviors on emotional experiences.
The purpose of this study was to investigate the relationship between emotional expression and experience in schizophrenia by manipulating expressive behaviors directly and then assessing subsequent emotional feelings. In Study 1, facial expressions and bodily postures were manipulated in a sample of normals, the results of which replicate findings from previous studies of peripheral feedback effects on emotions. In Study 2, the same procedures were used with matched groups of outpatient schizophrenic men, patients with depression, and nonpsychiatric controls. Schizophrenia patients showed the usual effects from their facial expressions of sadness, fear, happiness, and surprise, but only from their postures of anger, whereas patients with depression showed the same effects only from their expressions and postures of sadness, and normal controls only from their expressions and postures of anger. These patterns may reflect those aspects of the emotional response system that are functional and dysfunctional in schizophrenia and depression.
