Defective relationship between subjective experience and behavior in schizophrenia.
OBJECTIVE
The relationship between subjective experience and behavior abnormalities in schizophrenia was investigated.


METHODS
Eighteen patients with schizophrenia and 18 normal comparison subjects completed a general knowledge task with two incentive conditions to measure monitoring effectiveness, control sensitivity, and response criterion setting.


RESULTS
The patients' levels of monitoring effectiveness and control sensitivity were lower than those of the comparison subjects. The effect of incentives on response criterion values was similar in the two groups.


CONCLUSIONS
Patients were impaired in subjectively assessing the correctness of their knowledge, and their behavior was less determined by subjective experience than that of normal subjects. The patients' intact sensitivity to incentives has implications for cognitive remediation.
