我们最近的事件相关脑电位（ERP）研究将疼痛共情的神经机制分解为早期的自动情感分享成分和后期的受控认知评估过程。本研究通过比较男性和女性成人共情反应相关的erp，进一步探讨了疼痛共情神经机制的性别差异。研究人员向受试者展示了处于疼痛或无疼痛状态的手的照片，并要求他们完成一项需要注意刺激中的疼痛线索的疼痛判断任务，或完成一项将注意力从疼痛线索上移开的计数任务。我们发现，在刺激开始后140毫秒，男性和女性在额叶上表现出区分疼痛和中性刺激的短潜伏期共情反应，在中央顶叶区域380毫秒后表现出长潜伏期共情反应。然而，女性与男性的不同之处在于，长潜伏期共情反应受任务需求的调节更强，且140-180 ms的ERP振幅与主观报告他人感知痛苦程度和自我不愉快程度相关。我们的ERP结果为两性共情过程的早期和晚期成分的差异提供了神经科学证据。(C) 2008 Elsevier B.V.版权所有
Our recent event-related brain potential (ERP) study disentangled the neural mechanisms of empathy for pain into an early automatic emotional sharing component and a late controlled cognitive evaluation process. The current study further investigated gender difference in the neural mechanisms underlying empathy for pain by comparing ERPs associated with empathic responses between male and female adults. Subjects were presented with pictures of hands that were in painful or neutral situations and were asked to perform a pain judgment task that required attention to the pain cues in the stimuli or to perform a counting task that withdrew their attention from the pain cues. We found that both males and females showed a short-latency empathic response that differentiated painful and neutral stimuli over the frontal lobe at 140 ms after stimulus onset and a long-latency empathic response after 380 ms over the central-parietal regions. However, females were different from males in that the long-latency empathic response showed stronger modulation by task demands and that the ERP amplitudes at 140-180 ms were correlated with subjective reports of the degree of perceived pain of others and of unpleasantness of the self. Our ERP results provide neuroscience evidence for differences in both the early and late components of empathic process between the two sexes. (C) 2008 Elsevier B.V. All rights reserved.
