Practice effects on the modified Wisconsin card sorting test in normally aging adults

Does the Wisconsin Card Sorting Test Measure

Exploring age-related decline on the Wisconsin Card Sorting Test.

It is well established that performance on the Wisconsin Card Sorting Test (WCST) tends to decline with advanced age, but the reason for this decline has not been established. The objective of the present study was to clarify this question using a qualitative approach to the task. The WCST was administered to 19 older adults and 25 younger participants. In addition to standard testing procedure...

Brazilian preliminary norms and investigation of age and education effects on the Modified Wisconsin Card Sorting Test, Stroop Color and Word test and Digit Span test in adults

Executive functions are involved in a series of human neurological and psychiatric disorders. For this reason, appropriate assessment tools with age and education adjusted norms for symptom diagnosis are necessary. Objective To present normative data for adults (19-75 year-olds; with five years of education or more) on the Modified Wisconsin Card Sorting Test (MWCST), Stroop color and word te...

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...

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...
