Objective: The Wisconsin Card Sorting Test (WCST) is often regarded as a prototypical neuropsychological test of set-shifting ability. However, it has been proposed that WCST performance involves cognitive processes other than set shifting, such as set maintenance and rule inference. Distinguishing between these processes is necessary for the meaningful interpretation of WCST performance defici...
This study examined whether a measure of learning potential could predict work skill acquisition in schizophrenia beyond the prediction offered by a single administration assessment. Fifty-seven outpatients with schizophrenia or schizoaffective disorder completed a test-train-test version of the Wisconsin Card Sorting Test as a measure of their learning potential. The outpatients were randomly ...
Little is known about the individual factors that predict outcomes in Internet-administered psychological treatments. We hypothesized that greater cognitive flexibility (i.e. the ability to simultaneously consider several concepts and tasks and switch effortlessly between them in response to changes in environmental contingencies) would provide a better foundation for learning and employing the...

The contribution of dopaminergic systems to cognitive defects in Parkinson's disease and the cognitive effects of levodopa remain controversial. The levodopa plasma levels and the neuropsychological performance of 10 parkinsonian patients with a stable motor response to the drug and 10 matched parkinsonian patients with a 'wearing-off' phenomenon were studied 12 h after levodopa was withdrawn (...
Executive dysfunctions are considered to be putative markers of familial/genetic vulnerability to both schizophrenia and bipolar disorder. However, familial resemblance must be demonstrated before executive functions are used as a potential endophenotype. The aim of this study was to investigate familial resemblance for executive functions in families of schizophrenic and bipolar subjects. We a...
The cognitive flexibility to select appropriate rules in a changing environment is essential for survival and is assumed to depend on the integrity of prefrontal cortex (PFC). To explore the contribution of the dorsolateral PFC to flexible rule-based behavior, we recorded the activity of cells in this region of monkeys performing a Wisconsin Card Sorting Test (WCST) analog. The monkey had to ma...
