目的：本研究旨在探讨性别差异的时间动态体验共情通过使用electrophysiological measurements.Methods：25名女性和27名男性观看了414张图片的国际情感图片系统不同的情绪效价（积极的，消极的和中性的）和存在的人（人和场景）。EEG事件相关电位（ERPs）的获得和相关性进行了计算与自我报告的empathy.Results：相比男性，女性表现出增加前N2和顶叶LPP振幅人类对比的场景（独立的情绪效价）和负面对比中性情绪（独立的人类存在）。独立于性别的N1和前N2的积极的人类情绪和顶叶LPP的负面人类情绪特别增加。跨性别，N2和LPP的人类情感的影响和LPP的人类影响与自我报告的情感共情，但不与cognitive empathy.Conclusions：这项研究提供了电生理证据表明，妇女优先处理社会相关的和负面的情感信息，但妇女没有表现出增强的大脑潜力，以积极或消极的情绪在人类的图片。(C)2012爱思唯尔有限公司保留所有权利。
Objective: This study aimed to investigate sex differences in the temporal dynamics of experiencing empathy by using electrophysiological measurements.Methods: Twenty-five females and 27 males viewed 414 pictures of the International affective picture system varying in emotional valence (positive, negative and neutral) and presence of humans (human and scenes). EEG event related potentials (ERPs) were obtained and correlations were computed with self-reported empathy.Results: Compared to males, females showed increased anterior N2 and parietal LPP amplitudes to humans contrasted with scenes (independent of emotional valence) and to negative contrasted with neutral emotions (independent of human presence). Independent of sex the N1 and anterior N2 were specifically increased for positive human emotions and the parietal LPP for negative human emotions. Across sexes, the N2 and LPP human emotion effects and LPP human effects were associated with self-reported affective empathy, but not with cognitive empathy.Conclusions: This study provides electrophysiological evidence that women prioritize the processing of socially relevant and negative emotional information, but that women did not show enhanced brain potentials to pictures with positive or negative emotions in humans.
