The current study investigated how mechanisms of attention that have been well-characterized in the cognitive psychology literature (Lavie, Hirst, De Fockert, & Viding, 2004; Maylor & Lavie, 1998) may be differentially associated with psychopathic traits in nonincarcerated men. Previous research on cognition and psychopathy indicated that primary psychopathic traits were associated with overfocused attention and/or reduced processing of information peripheral to the focus of attention. Conversely, deficits in executive functioning, such as working memory and cognitive control, were implicated in secondary psychopathic traits. Results revealed a significant relationship between traits typically associated with primary psychopathy (e.g., low anxiety, social dominance, fearlessness, callousness) and reduced processing of task-irrelevant distractors, suggesting diminished basic attentional capacity among individuals high on these traits. In contrast, some characteristics linked to secondary psychopathy (e.g., social alienation, cynicism) showed a positive relationship with impaired working memory functioning, indicative of deficits in cognitive control, whereas other traits (i.e., self-centeredness, antagonism) did not. These results suggest that psychopathic traits are differentially related to selective impairments in attentional functioning, which may help explain the observed heterogeneity in psychopathic manifestations.
当前的研究调查了认知心理学文献中已得到充分描述的注意力机制(拉维、赫斯特、德福克特和维丁,2004年;梅勒和拉维,1998年)如何与未被监禁男性的精神病态特质存在差异关联。先前关于认知与精神病态的研究表明,原发性精神病态特质与过度聚焦的注意力和/或对注意力焦点之外信息的处理减少有关。相反,执行功能缺陷,如工作记忆和认知控制,与继发性精神病态特质有关。结果显示,通常与原发性精神病态相关的特质(如低焦虑、社会支配性、无畏、冷酷无情)与对任务无关干扰物的处理减少之间存在显著关系,这表明具有这些特质的个体基本注意力能力减弱。相比之下,与继发性精神病态相关的一些特征(如社会疏离、愤世嫉俗)与工作记忆功能受损呈正相关,表明存在认知控制缺陷,而其他特质(即以自我为中心、敌对)则不然。这些结果表明,精神病态特质与注意力功能的选择性损伤存在差异关联,这可能有助于解释在精神病态表现中观察到的异质性。
