The effectiveness of a training procedure to improve schizophrenic pat
ients' Wisconsin Card Sorting Test performance was investigated. In th
e absence of the monetary incentive often employed, 10 schizophrenic i
n-patients' performance improved with training. This study provides fu
rther evidence that the cognitive deficiency associated with the front
al lobe, implied by schizophrenic patients' typically poor Wisconsin C
ard-Sorting Test performance, is remediable.
