视觉定向任务揭示了精神分裂症患者注意力分散受损。我们使用提示目标检测（间隙与无间隙）和选择反应时间任务，探索了 20 名精神分裂症患者 (SZ)、20 名全兄弟姐妹 (FS) 和 20 名对照者 (C) 的视觉定向。 SZ 的反应时间较长，但 FS 的反应时间与警告的反应相当。与 C 相比，SZ 和 FS 没有表现出显着的间隙效应。精神分裂症患者及其兄弟姐妹的脱离缺陷为改变早期注意力机制（精神分裂症患者及其非精神病亲属）提供了论据。
Visual orienting tasks reveal an impaired disengagement of attention in schizophrenia. We explored visual orientation in 20 schizophrenia patients (SZ), 20 full siblings (FS), and 20 controls (C) using a cued target detection (gap vs. no gap) and a choice reaction time task. SZ but not FS had longer reaction time with comparable reactions to warning. In contrast to C, SZ and FS did not display a significant gap effect. The disengagement deficit in schizophrenia patients and their siblings provides arguments for altered early attention mechanisms (in schizophrenic patients and their nonpsychotic relatives).
