Abstract

This experiment tested the idea that there is cognitive differentiation between paranoid and nonparanoid schizophrenics. Paranoids utilize a conceptual style of responding more than nonparanoid schizophrenics. Eight male nonparanoid, 8 paranoid, and 8 nonschizophrenic controls responded to ambiguous slides of common objects in a visual discrimination task. The slides were presented in several different contexts. The results were as expected. Paranoids gave responses following the dominant conceptual cues significantly more than nonparanoid schizophrenics. Paranoids and controls followed these cues equally frequently although paranoids tended to follow them more when it hindered success than controls or nonparanoids. This evidence of cognitive differentiation between schizophrenic subtypes warrants cross-validation on a larger sample.
