A Comparative Study on the Cognitive Dysfunction between Positive and Negative Schizophrenics

This study was conducted to compare the differences in cognitive dysfunction between positive and negative schizophrenics. The subjects of the study consisted of 30 normal controls, 30 positive schizophrenics and 30 negative schizophrenics. Gamer-typed card sorting, Bender-Gestalt test and mini-mental state test were administered to each subject. The results were as follows &#8226; 1) For the‘ card sorting of low discriminability, the sorting times were significantly different among the three groups * the longest in the negative schizophrenics and the shortest in the controls(P<0.01). But, there was no significant difference between positive and negative schizophrenic groups. 2) For the Bender-Gestalt test, the Z-scores were significantly different among the three grops : the highest in the negative schizophrenics and the lowest in the controls(P<0.01), and the Z-score was significantly lower in the positive than in the negative schizophrenic groups (p < 0 .0 l). 3) For the mini-mental state test, the scores were significantly different among the three groups * the highest in the controls and the lowest in the schizophrenics(P<0.0l). In the comparison between positive and negative schizophrenic groups, the score was significantly higher in the former than in the latter(P<0.01).
