Test-retest stability of the Wisconsin card sorting test (WCST)

Electrophysiological correlates activated during the Wisconsin Card Sorting Test (WCST).

In the present study we investigated changes in Event-Related Potentials (ERPs) during the Wisconsin Card Sorting Test (WCST) in order to identify cognitive processes underlying the set-shifting aspects of the task and to determine test sensitivity for frontal and prefrontal cortical areas. ERP's were recorded from a sample of 20 healthy adults while they performed a computerized version of the...
