Study on the Wisconsin Card Sorting Test among Early and Late Onset Schizophrenia: A Comparative Clinical Study

Background – WCST is the commonly and globally most widely used psychological test, which measures the executive function. Research related to WCST performance reveals that schizophrenia clients have consistently been shown to perform worse than normal controls on the WCST in all dimensional aspects. Hence, in this study, we have tried to investigate this relationship between the WCST performance and an early onset schizophrenic and late onset schizophrenia with a specific emphasis on the executive function dichotomy on this test.
