Wisconsin Card Sorting Test-64
Also written as: WCST-64 — Wisconsin Card Sorting Test-64
A shortened version of the classic WCST that assesses cognitive flexibility and set-shifting abilities using 64 cards.
Full Definition
The Wisconsin Card Sorting Test-64 (WCST-64) is an abbreviated version of the original 128-card Wisconsin Card Sorting Test, designed to assess executive functioning, particularly cognitive flexibility, set-shifting, and abstract reasoning. The test requires participants to sort cards according to changing rules (color, form, or number) without explicit instruction, forcing them to deduce the correct sorting principle through feedback. The 64-card version reduces administration time while maintaining psychometric properties, making it more practical for clinical use. Key outcome measures include perseverative errors, conceptual level responses, and categories completed. The WCST-64 is particularly sensitive to frontal lobe dysfunction and is widely used in neuropsychological assessment batteries.
Usage
Usage note: Specify the 64-card version to distinguish from the original 128-card test.
