Wisconsin Card Sorting Test
Neuropsychological test measuring abstract reasoning, cognitive flexibility, and perseverative responding.
Full Definition
A computerized or manual test requiring participants to match cards according to changing rules (color, form, or number) without explicit instruction about the sorting principle. The test measures the ability to shift cognitive set, form abstract concepts, and learn from feedback. Key measures include categories completed, perseverative errors, and failure to maintain set. It is particularly sensitive to frontal lobe dysfunction.
