Competing hypotheses that explain the effects of emotionally arousing, extraneous auditory stimuli on the social cue perception of schizophrenic patients were examined in this study: (1) extraneous arousing stimuli enhance patients' cue perception; (2) extraneous stimuli distract patients, and cue perception is diminished. Twenty-five patients with DSM-III-R diagnoses of schizophrenia completed a cue-perception task in which half of the videotaped vignettes included in the task were presented with simultaneous extraneous stimuli and half were not. Item difficulty and consistency across extraneous stimuli conditions were matched on standardization and cross-validation samples. Results showed that schizophrenic subjects were significantly more sensitive to cues when exposed to extraneous stimuli, thereby supporting the first hypothesis. This effect was also observed in a subgroup of schizophrenic subjects who demonstrated a distraction decrement on another test of short-term recall. The presence of extraneous stimuli interacted with perception of abstract cues; that is, schizophrenic subjects were particularly better at perceiving abstract cues when extraneous stimuli were presented simultaneously. Future research needs to determine characteristics of extraneous stimuli that enhance cue perception. |
