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