Reduction of perseverative errors in patients with schizophrenia using monetary feedback

A T Summerfelt et al. J Abnorm Psychol. 1991 Nov.

Abstract

The influence of monetary feedback on Wisconsin Card Sort Test (WCST) performance of 14 male schizophrenics was investigated. Patients were administered the test under standard instructions and with monetary feedback in counterbalanced order. Monetary reinforcement reduced perseverative errors and increased correct responses (p less than .05). These findings suggest that the WCST perseverative errors of schizophrenics reflect motivational as well as cognitive factors.
