Wisconsin card sorting test and Stroop test performance in schizophrenia: a shared construct.
The Wisconsin card sorting test (WCST) and Stroop test were administered to 25 schizophrenic patients in order to better identify and understand more specific processing mechanisms involved in executive dysfunctions and to investigate their hypothetical involvement in symptom formation. Data show that for as much as the two tests employed measured executive functions in terms of mental control and cognitive flexibility, our findings seemed to indicate shared or interconnected mechanisms. No correlations were seen between the psychopathological evaluation and any of the neuropsychological indexes. The use of the Stroop task could provide a more readily cognitive analysis in terms of specific processing mechanisms, at the basis of WCST impairment in schizophrenia.
