A Study on the Memory Performance in Positive and Negative Symptom Schizophrenics

This study was designed to investigate memory performance in positive and negative symptom schizophrenics. The subjects consisted of 3 groups of 40 positive symptom schizophrenics, 40 negative symptom schizophrenics, and 40 normal controls. Before the Memory performance test, 3 groups were matched to age, sex, scaled score of information of K-WAIS, duration of illnes and daily dose of antipsychotics. Analyses were done by scores of recall and recognition task, scores of memoiy clustering and recognition error. The results were as follows: 1) For the free recall, the schizophrenics(positive and negative group) showed significantly lower scores than normal controls(p〈.05). Negative group showed significantly lower scores than positive group(p<C.05). Cue conditioned schizophrenics showed significantly high scores than non-cue conditioned schizophrenics. 2) For the memory clustering of free recall task, schizophrenics showed significantly lower scores than normal controls(p<C05). But there was no significant difference between positive and negative group. Cue conditioned schizophrenics showed significantly higher scores than non-cue conditioned schizophrenics. 3) For the memory strategy, normal controls exhibited semantic clustering. But schizophrenics exhibited serial clustering. 4) For the recognition, there was no significant difference between positive group and normal controls. But negative group showed significantly lower scores than positive group and normal controls(p〈05). There was no cuing effect among 3 groups. 5) For the recognition error, schizophrenics showed significantly lower scores than normal controls (p<C05). But there was no significant difference between positive and negative group. There was no cuing effect among 3 groups. In conclusion, this study suggests positive symptom schizophrenics exhibited memory deficit
