Abstract：
This study examined the empathic processing of individuals with psychopathic traits and healthy controls in response to pain, applying affective perspective-taking (Self vs. Other). Twenty subjects with high psychopathic traits and twenty control subjects performed pain judgment tasks in the study. During the tasks, late positive potentials (LPPs) of the participants were measured to assess emotional processing in reaction to visual stimuli depicting painful or non-painful situations. In early LPP time stage (500-700 ms), the control group and the psychopathic trait group exhibited comparable levels of empathic processing regarding pain. However, in late LPP time window (700-1100 ms), the control group showed a greater LPP amplitude to Pain stimuli than No-pain stimuli, whereas the psychopathic trait group exhibited non-significant amplitude differences between Pain and No-pain stimuli. These findings imply that individuals with high psychopathic traits may swiftly terminate the processing and encounter difficulties in reappraising distress cues, especially in the late stage, providing psychophysiological support for distinctive empathic processing with temporal aspects.
摘要：
这项研究检查了具有精神病特征和健康对照者对疼痛的反应的移情过程，应用情感视角(自我与其他）。研究中，有20名具有高精神病特征的受试者和20名对照受试者执行了疼痛判断任务。在任务期间,测量参与者的晚期正电位(LPP),以评估对描述疼痛或非疼痛情况的视觉刺激的反应中的情绪处理.在早期LPP时间阶段（500-700ms），对照组和精神病特质组在疼痛方面表现出相当的移情处理水平.然而,在LPP后期时间窗口（700-1,100ms），对照组对疼痛刺激的LPP振幅大于无痛刺激，而精神病特质组的疼痛和无痛刺激之间的振幅差异不显著。这些发现暗示，具有高精神病特征的个体可能会迅速终止处理，并在重新评估痛苦线索时遇到困难，尤其是在后期，为时间方面的独特移情处理提供心理生理支持。
