精神病患者在处理情绪信息时表现出异常，但关于注意力在这些过程中所起的作用，人们还不太确定。我们目前的数据从两个情感图片观看任务比较事件相关电位（ERP）调制效应时，情绪信息是存在的，但不任务相关的（任务1），其次是一个条件，将注意力集中到情感内容的分类（任务2）。控制显示出强大的，持久的ERP阳性（200900？ms）与情感目标照片相关联，而中性目标在两个任务中。精神病患者只有在明确关注照片的情感内容时才表现出这种差异（任务2），这些影响仍然小于对照组所表现出的幅度差异。虽然注意力的异常分配可能起着关键作用，但这不能完全解释与精神病相关的情绪处理缺陷。
Psychopaths exhibit abnormalities processing emotional information, but there is less certainty regarding the role attention plays in these processes. We present data from two affective picture-viewing tasks comparing event-related potential (ERP) modulation effects when emotional information is present but not task relevant (Task 1) followed by a condition directing attention to the categorization of emotional content (Task 2). Controls show a robust, persistent ERP positivity (200900?ms) associated with emotional target photos compared to neutral targets in both tasks. Individuals with psychopathy only showed this differentiation when explicitly attending to the emotional content of the photos (Task 2), and these effects remained smaller than the amplitude differences demonstrated by controls. Although abnormal allocation of attention may play a critical role, this cannot completely account for emotional processing deficits associated with psychopathy.
