With a delayed-response task, spatial working memory function was assessed in normal students who were selected for schizotypy. The Wisconsin Card Sorting Test was also administered. Twenty-eight undergraduate students who scored high on the Perceptual Aberration Scale (PerAb) and 23 who scored low on this scale participated in this study. High PerAb students performed less accurately compared with the low PerAb controls on the delayed-response task, and they were more than twice as likely as low PerAb students to be impaired. The groups did not differ in the number of perseverative errors or number of categories achieved on the Wisconsin Card Sorting Test, but, as predicted, high PerAb students were less able to maintain set than were the low PerAb students. Neuropsychological implications of these data are discussed.
通过一项延迟反应任务，对被选作具有分裂型人格特质的正常学生的空间工作记忆功能进行了评估。同时还进行了威斯康星卡片分类测试。28名在感知异常量表（PerAb）上得分高的本科生和23名在该量表上得分低的本科生参与了本研究。与低PerAb对照组相比，高PerAb学生在延迟反应任务中的表现准确性较低，并且他们出现功能受损的可能性是低PerAb学生的两倍多。两组在威斯康星卡片分类测试中的持续性错误数量或达到的类别数量上没有差异，但正如预期的那样，高PerAb学生比低PerAb学生更难以维持定势。本文讨论了这些数据的神经心理学意义。
