Selective deficits in visual perception and recognition in schizophrenia

OBJECTIVE: The purpose of this study was to evaluate the performance of
patients with schizophrenia on tests of visual discrimination and
recognition of different stimulus features. METHOD: Thirteen medicated male
schizophrenic patients and 13 normal comparison subjects were tested on
four stimulus features: spatial frequency, pattern, location, and
trajectory. Subjects had to make both discrimination and recognition
judgments at three levels of stimulus disparity. RESULTS: The responses of
the patient group were slower and less accurate than those of the
comparison group on both the discrimination and recognition tasks. The
patients were less accurate than the comparison subjects in processing
spatial features of the stimuli, particularly trajectory, but were
unimpaired in processing form attributes (high spatial frequencies and
patterns). When the results of pattern and trajectory tasks were matched
against the accuracy performance of the comparison group, the patients were
less accurate on trajectory than on pattern judgments and less accurate on
recognition than on discrimination performance. CONCLUSIONS: Schizophrenia
may be accompanied by impaired visual spatial perception and
representation. In schizophrenia, deficits in trajectory discrimination may
reflect a disturbance of the dorsal pathway of the visual system, while
disturbances of trajectory recognition performance may reflect a deficit in
prefrontal systems involved in visual working memory operations.
