title: Poorer Wisconsin card-sorting test performance in healthy adults with higher positive and negative schizotypal traits.
abstract: Non-clinical schizotypy was found to be related to poorer Wisconsin Card-Sorting Test (WCST) performance, but the results were inconsistent. Two subgroups, the higher negative-higher positive and the lower negative-lower positive (15 vs 16), were selected from the top and the bottom quartiles of negative and positive scale scores of the Schizotypal Personality Questionnaire (SPQ) completed by 177 healthy volunteers, respectively. The higher negative-higher positive SPQ score subgroup had significantly poorer performance regarding the completed categories of WCST than the lower negative-lower positive SPQ score subgroup. Subjects with higher non-clinical schizotypy trait showed relatively mild cognitive dysfunction.
