title: Sensory perceptual limitation in schizophrenia.
abstract: Sensory perception and selective attention capacity of schizophrenic patients have drawn particular interest. Schizophrenic patients show a peculiar deficit in screening and processing of incoming sensory data. Review of the literature suggests a breakdown in the selective-inhibitory function of attention in schizophrenic patients facing multiple sensory modalities. Although disorganization of attention is a focal point in schizophrenic perception, the influence of memory on the perceptual process deserves further investigation. Distracting sensory stimuli particularly of an auditory nature seem to interfere with visual perception and motor performance in these patients. Avoidance of sensory overload and improving selective attention through psychotherapy though of some therapeutic value, requires further exploration. A case of a young schizophrenic patient exposed to distractible environmental stimuli was presented and discussed.
