Psychopathic individuals are notorious for their callous disregard for others' emotions. Prior research has linked psychopathy to deficits in affective mechanisms underlying empathy (e.g., affective sharing), yet research relating psychopathy to cognitive mechanisms underlying empathy (e.g., affective perspective-taking and Theory of Mind) requires further clarification. To elucidate the neurobiology of cognitive mechanisms of empathy in psychopathy, we administered an fMRI task and tested for global as well as emotion-specific deficits in affective perspective-taking. Adult male incarcerated offenders (N = 94) viewed images of two people interacting, with one individual's face obscured by a shape. Participants were cued to either identify the emotion of the obscured individual or identify the shape from one of two emotion or shape choices presented on each trial. Target emotions included anger, fear, happiness, sadness, and neutral. Contrary to predictions, psychopathy was unrelated to neural activity in the Affective Perspective-taking > Shape contrast. In line with predictions, psychopathy was negatively related to task accuracy during affective perspective-taking for fear, happiness, and sadness. Psychopathy was related to reduced hemodynamic activity exclusively during fear perspective-taking in several areas: left anterior insula extending into posterior orbitofrontal cortex, right precuneus, left superior parietal lobule, and left superior occipital cortex. Although much prior research has emphasized psychopathy-related abnormalities in affective mechanisms mediating empathy, current results add to growing evidence of psychopathy-related abnormalities in a cognitive mechanism related to empathy. These findings highlight brain regions that are hypoactive in psychopathy when explicitly processing another's fear.
反社会人格者以对他人情感的冷漠无视而臭名昭著。先前的研究将反社会人格与同理心的情感机制缺陷联系起来(例如,情感共鸣),但将反社会人格与同理心的认知机制联系起来的研究(例如,情感换位思考和心理理论)需要进一步澄清。为了阐明同理心认知机制的神经生物学,我们进行了 fMRI 任务,并测试了情感换位思考的整体和特定于情绪的缺陷。成年男性囚犯(N=94)观察了两个人互动的图像,其中一个人的脸被形状遮挡。参与者被提示识别被遮挡者的情绪,或从每个试验呈现的两个情绪或形状选择之一中识别形状。目标情绪包括愤怒、恐惧、快乐、悲伤和中性。与预测相反,反社会人格与情感换位思考>形状对比中的神经活动无关。与预测一致,反社会人格与恐惧、快乐和悲伤的情感换位思考任务准确性呈负相关。反社会人格与恐惧视角特定任务中的几个区域的血液动力学活动减少有关:左侧前岛叶延伸到后眶额皮质、右侧顶内小叶、左侧上顶叶和左侧上枕叶。尽管先前的许多研究强调了同理心情感机制中介的反社会人格相关异常,但目前的结果增加了与同理心相关认知机制异常的证据。这些发现突出了在明确处理他人恐惧时反社会人格中活动不足的脑区。
