This study examined the early visual perceptual process in schizophrenic patients using tasks with variables related to perceptual organization. The results show that schizophrenic subjects organiz the unorganized visual field less efficiently than normals and their information extracting ability from visual field is impaired significantly. Distractors have significantly more influence on schizophrenic patients than normals, so patients make significantly more errors with unorganized and organized stimuli, but normals make more errors only with unorganized stimuli. It is suggested that schizophrenic's inability to organize visual field efficiently and of information extracting are due to their inability to deal with stimuli as a whole, which result in increasing informational units to be processed.
