Information processing strategy to remediate Wisconsin Card Sorting Test performance in schizophrenia: a pilot study.

A modified procedure for administering the Wisconsin Card Sorting Test, focusing on a hypothesized deficit of organizational strategy in information processing, was used to administer the test to 20 schizophrenic patients. By using this procedure, 61.5% of the poor performers (eight of 13) were dramatically transformed into good performers without any task instruction or reinforcement. The results, albeit preliminary, support the hypothesis and the possibility of remediating the task performance of some schizophrenic patients.
