We examined sustained attention in 32 schizotypic and 43 normal control subjects from a large, randomly ascertained nonclinical university population. Schizotypy status was determined with the Perceptual Aberration Scale. Sustained attention was measured with the Continuous Performance Test-Identical Pairs. Schizotypic subjects displayed significantly poorer sustained-attention performance than did control subjects, as measured by d and overall hit rate. Although schizotypic subjects evidenced greater levels of anxiety and depression, sustained-attention performance was not significantly associated with these mental state factors. Our results provide evidence for a subtle sustained-attention deficit among schizotypes and are interpreted in light of previous attention research with actual schizophrenic patients as well as children at risk for schizophrenia. Utility of the psychometric high-risk strategy in psychopathology research is discussed.
我们从一个大型随机抽取的非临床大学人群中选取了32名分裂型人格特质者和43名正常对照者，对他们的持续性注意力进行了检测。采用感知偏差量表确定分裂型人格特质状态。使用连续性能测试-相同配对任务来测量持续性注意力。通过d值和总体命中率测量发现，分裂型人格特质者的持续性注意力表现显著差于对照者。尽管分裂型人格特质者表现出更高水平的焦虑和抑郁，但持续性注意力表现与这些心理状态因素并无显著关联。我们的研究结果为分裂型人格特质者存在细微的持续性注意力缺陷提供了证据，并根据之前对实际精神分裂症患者以及有精神分裂症风险儿童的注意力研究进行了解释。同时讨论了心理测量高危策略在精神病理学研究中的效用。
