    Objectives: The purpose of this study was to examine the performance of schizophrenic patients on the Iowa Gambling Task(lGT). In addition, it was aimed to test whether the performance on IGT is related to working memory within schizophrenic group.
    Methods: Twenty-three stable schizophrenic patients and twenty-eight control subjects underwent computerized versions of the IGT and the Wisconsin Card Sorting Test(WCST).
    Results: Schizophrenic patients performed poorly on IGT relative to normal controls. On WCST performance, schizophrenic patients completed significantly fewer categories and made more errors than controls did. There was no significant relationship between IGT and WCST performance.
    Conclusion: It was suggested that schizophrenic patients have impaired decision-making and the performance on IGT is separable from cognitive functions considered to be related to dorsolateral prefrontal cortex.
