πŸ“š Quick Study Guide

  • 🧠 The Wisconsin Card Sorting Test (WCST) assesses executive functions, including cognitive flexibility, set-shifting, and abstract reasoning.
  • πŸ§ͺ Participants are presented with cards and asked to match them based on a rule (color, shape, or number), which changes periodically without warning.
  • πŸ’‘ The test reveals how well individuals can adapt to changing rules and inhibit previously correct responses.
  • πŸ“Š Performance is measured by the number of categories achieved, errors made (perseverative and non-perseverative), and trials to complete the first category.
  • πŸ§‘β€βš•οΈ It is used to detect frontal lobe damage, schizophrenia, and other cognitive impairments.
  • ⏱️ The WCST typically takes 15-20 minutes to administer.
  • πŸ“ Perseveration is a key concept, referring to the continued use of a previously correct rule despite feedback indicating it is no longer correct.
