认知 - 注意因素可能会调节与精神病态相关的情感缺陷（纽曼和洛伦兹，2003）。本研究考察了这些因素在调节作为无畏支配和冲动反社会性（与精神病态相关的人格维度）的函数的恐惧增强惊跳反应（FPS）中的作用。大学生完成一项任务，该任务要求他们在（a）低工作记忆负荷下关注威胁维度，（b）低负荷下关注与威胁无关的维度，或（c）高负荷下关注与威胁无关的维度。注意焦点，而非工作记忆负荷，调节了无畏支配和FPS之间的关系。只有当注意力从威胁上转移开时，无畏支配才与FPS呈负相关。对于冲动反社会性没有显著发现。结果提供了证据，表明与精神病态相关的恐惧反应降低可能是由一种注意机制导致的。
Cognitive-attentional factors may moderate emotion deficits associated with psychopathy (Newman & Lorenz, 2003). This study examined the role of these factors in moderating fear-potentiated startle (FPS) as a function of Fearless Dominance and Impulsive Antisociality-personality dimensions with links to psychopathy. University students performed a task that required them to focus on a (a) threat dimension under low working memory load, (b) threat-irrelevant dimension under low load, or (c) threat-irrelevant dimension under high load. Attentional focus, but not working memory load, moderated the relationship between Fearless Dominance and FPS. Fearless Dominance was negatively correlated with FPS only when attention was directed away from the threat. There were no significant findings for Impulsive Antisociality. Results provide evidence that reduced fear response associated with psychopathy may result from an attentional mechanism.
