Thinking disturbance and disorder of affects may be different in two subtypes of schizophrenia, the "florid" and the "withdrawal" syndromes. In Exner's approach to the Rorschach system, the diagnostic indicators of disordered thinking may point out large differences not only between schizophrenic and control subjects but also between different types of schizophrenics. The Rorschach protocols of 45 subjects (15 "florid" schizophrenics, 15 "withdrawn" schizophrenics, and 15 controls of the same age and education, matched by sex) were examined on several Exner indices. Compared with the control group, both schizophrenic types confirmed an impairment of perceptual accuracy and of reality testing as well as a reduced emotional control. Compared with the "withdrawn" group, the "florid" schizophrenic subjects showed significantly higher indices of poor perceptual functioning, of an inadequate organizational activity (more Whole and Z responses characterized by negative Form Quality) and greater disordered ideational production.
