A Model of Cognitive Control in the Wisconsin Card Sorting Test: Integrating Schema Theory and Basal Ganglia Function

We present a schema-based model of a classic neuropsychological task, the Wisconsin Card Sorting Task (WCST), where competition between motor and cognitive schemas is resolved using a variation of a neuroanatomically detailed model of the basal ganglia (Gurney et al., 2001). We show that the model achieves a good fit with existing data at the group level, and correctly identifies two distinct c...

The role of attention in Wisconsin Card Sorting Test performance.

The present study sought to test the hypothesis that the second factor (consisting of Failure-to-Maintain-Set and other scores) found in two recent factor analyses of the Wisconsin Card Sorting Test reflects attentional function. The effect of color overlays (an experimental manipulation known to influence neural systems linked to attention) was examined in 17 normal control and 14 attention-di...

emotional intelligence and prefrontal cortex: a comparative study based on wisconsin card sorting test (wcst)

ôbjective: ëmotional intelligence (ëï) is a set of competencies that enable us to engage in sophisticated information processing of emotions and emotion-relevant stimuli and to use this information as a guide for thinking and behavior. prefrontal cortexes (pfç) of brain and related regions have an important role in emotion and emotional regulation. âccordingly, we conducted a study to investiga...

Perceptual aberrations, schizotypy, and the Wisconsin Card Sorting Test.

This study examined performance on the Wisconsin Card Sorting Test (WCST) by 23 schizotypic subjects and 28 normal control subjects. Schizotypy was measured on the Perceptual Aberration Scale (PAS). Overall, schizotypic (high PAS) subjects performed more poorly than control (low PAS) subjects on the WCST; specifically, schizotypic subjects showed deficits on the failure-to-maintain-set and numb...
