Attentional Characteristics of Schizophrenia Patients Differing in Learning Proficiency on the Wisconsin Card Sorting Test

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...

Does the Wisconsin Card Sorting Test Measure

Attentional set shifting modulates the target P3b response in the Wisconsin card sorting test.

For years the Wisconsin card sorting test (WCST) has been used as a test of frontal lobe function. Recent event-related potential (ERP) research has shown large differences in the amplitude of P3b responses evoked by early and late trials within each WCST series ([8]: Barceló F., Sanz M., Molina V., Rubia FJ. The Wisconsin Card Sorting Test and the assessment of frontal function: A validation s...

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...
