Perceptual organization in schizophrenia: utilization of the Gestalt principles.
In 2 experiments, the authors investigated perceptual organization in schizophrenia to determine whether patients with schizophrenia used the Gestalt principles. In the visual embedded figures task (Experiment 1), the authors examined the principles of proximity and collinearity, whereas in the similarity task (Experiment 2), the authors examined similarity. Forty-three people participated in the study: patients diagnosed with schizophrenia (14) or with bipolar disorder (15), and "normal" participants (14). All 3 groups of participants showed performance superiority in the condition that was facilitated by the use of the Gestalt principles in both tasks. This study supports the hypothesis that visual perceptual organization, in terms of utilizing the Gestalt principles, is relatively intact in people with schizophrenia.
