A comparison of remediation techniques on the Wisconsin Card Sorting Test in schizophrenia

Does the Wisconsin Card Sorting Test Measure

Attentional characteristics of schizophrenia patients differing in learning proficiency on the Wisconsin Card Sorting Test.

The Wisconsin Card Sorting Test (WCST), a test of concept formation, was given to 49 schizophrenia inpatients in three blocks of 64 cards each with the second block comprising special instructions and trial-by-trial feedback. With the help of a psychometric algorithm based on linear regression analysis, the patients were classified according to their response to these specific interventions. Re...

Performance of patients with schizophrenia on the Wisconsin Card Sorting Test (WCST).

OBJECTIVE To directly compare the performance of patients with schizophrenia and control subjects on the Wisconsin Card Sorting Test (WCST). Specifically, we sought to verify if there are significant differences on the "classical" WCST measurements (perseverative errors and number of categories), as well as on more rarely reported scores, and assess the extent to which patients with schizophren...

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...

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...
