Anhedonia, perceptual aberration, and the Rorschach

26 college students who scored deviantly high on a scale of physical anhedonia and 27 who scored high on a scale of perceptual aberration were compared with 26 normal control Ss on the Rorschach scored for the delta index of thought disorder and the alpha index of deviancy. The anhedonic Ss and perceptual aberration Ss gave more schizophrenic-like Rorschach responses than the control Ss. This finding indicates the importance of follow-up studies to determine whether Ss who score deviantly high on these scales are at high risk for schizophrenia and/or other psychosis. (42 ref)
