Responses of schizophrenics and nonpatients to a tachistoscopic presentation of the Rorschach.

Three groups of 36 subjects each, two of nonpsychiatric subjects and one of first admission schizophrenics, were administered the Rorschach tachistoscopically. Each group was subdivided into three subgroups to permit a variation in exposure times for the blots. Intervals of 200ms, 400ms, and 600ms were used; however, the differences in exposure times did not produce significant differences within any of the groups. Thus, the data were compared by groups. The results indicate no significant differences across the groups for accuracy of from (X + %). The schizophrenic group did give significantly more Special Scores related to cognitive slippage. They also gave a much higher proportion of pure form responses and substantially more card rejections than either of the nonpsychiatric groups. The results are discussed in the context of research on information processing and the early operations in the Rorschach response process.
