Abstract
The Wisconsin Cart Sorting Test (WCST) is a well-established measure of executive function. Practical and financial constraints have increased the need for abbreviated neuropsychological procedures. A number of abbreviated versions of the WCST have been introduced and cogent arguments can be made for one over another in certain situations. However, the single deck, 64-card WCST (WCST-64) is the most logical and practical short form. Psychological Assessment Resources (PAR) has recently published a new manual with comprehensive norms for the WCST-64. This paper reviews the new product, discusses the comparability of the WCST-64 and the standard version, and suggests directions for future research.
