BACKGROUND
Although one of the main characteristics of psychopaths is a deficit in emotion, it is unknown whether they show a fundamental impairment in appropriately recognizing their own body sensations during an emotion-inducing task.
METHOD
Skin conductance and heart rate were recorded in 138 males during a social stressor together with subjective reports of body sensations. Psychopathic traits were assessed using the Psychopathy Checklist-Revised (PCL-R) 2nd edition (Hare, 2003).
RESULTS
Nonpsychopathic controls who reported higher body sensations showed higher heart rate reactivity, but this verbal-autonomic consistency was not found in psychopathic individuals. This mind-body disconnection is particularly associated with the interpersonal-affective factor of psychopathy.
CONCLUSIONS
Findings are the first to document this body sensation-autonomic mismatch in psychopaths, and suggest that somatic aphasia - the inaccurate identification and recognition of one's own somatic states - may partly underlie the interpersonal-affective features of psychopathy.
背景
尽管精神病态者的主要特征之一是情绪缺失，但目前尚不清楚他们在进行情绪诱发任务时是否表现出对自身身体感觉的基本识别障碍。
方法
在社会压力源期间，记录了 138 名男性的皮肤电导和心率，并伴有身体感觉的主观报告。使用第二版《精神病态检查表修订版》（PCL-R）（Hare，2003 年）评估精神病态特征。
结果
报告身体感觉较高的非精神病态对照组显示出更高的心率反应性，但这种言语自主一致性在精神病态个体中未被发现。这种身心脱节与精神病态的人际情感因素特别相关。
结论
研究结果首次记录了精神病态者的这种身体感觉与自主反应不匹配现象，并表明躯体失语症 - 即对自身躯体状态的不准确识别和认知 - 可能部分构成了精神病态的人际情感特征的基础。
