<p>A group of forty schizophrenics hospitalized in a psychiatric in­stitution were studied regarding some aspects related to their cogni­tive styles and compared to three samples of normal school children to establish the relative level of psychological differentiation of the experimental group.</p><p>The results suggest a “syndrome of low response” in the schizophren­ic group who presented a greater number of analytical responses, as measured by the tests of conceptual style of Kagan, than the younger group in the control sample. These data show the coarctated char­acter and poor discrimination of the schizophrenics before percep­tual stimuli and bring us to face an interesting problem noted by this failure in perceptual organization. It has been considered by various authorities that the analytic-global dimension was the prin­ciple of cognitive control. It is expected that such processes ex­plain in part the schizophrenics’ inadequacy in social situations and in relation to the “reality principle.”</p>
