The present study investigated about the influence of intensive training and contingent reinforcement on WCST performance of the patient with schizophrenia. Subjects were 36 persons, schizophrenia diagnosed by psychiatrists based on criteria by DSM-IV and the normal control subjects were 12 persons. Intensive training reduced perseverative errors, number of trials to complete the first category and increased correct responses and completed category, percent conceptual level responses score, but these subject's training effect was not maintained after a week. The results indicate that deficits in performance on the WCST are improvable by intensive training.
