title: Construct validity of neuropsychological tests of conceptual and attentional abilities.
abstract: In a mixed sample of community-living adults, this study examined the construct validity of five neuropsychological tests: Category Test (CAT), Wisconsin Card Sorting Test (WCST), Paced Auditory Serial Addition Task (PASAT), Visual Search and Attention Test (VSAT) and Trail Making Test: Part B (TMT-B). Principal components analyses showed that PASAT, VSAT, and TMT-B defined an attention factor and that CAT and WCST defined a conceptual factor. The results were discussed in terms of common interpretations of these procedures as well as in terms of Mirsky's (1989) components of attention.
