There is evidence that women and men show differences in the perception of affective facial expressions. However, none of the previous studies directly investigated sex differences in emotional processing of own-race and other-race faces. The current study addressed this issue using high time resolution event-related potential techniques. In total, data from 25 participants (13 women and 12 men) were analyzed. It was found that women showed increased N170 amplitudes to negative White faces compared with negative Chinese faces over the right hemisphere electrodes. This result suggests that women show enhanced sensitivity to other-race faces showing negative emotions (fear or disgust), which may contribute toward evolution. However, the current data showed that men had increased N170 amplitudes to happy Chinese versus happy White faces over the left hemisphere electrodes, indicating that men show enhanced sensitivity to own-race faces showing positive emotions (happiness). In this respect, men might use past pleasant emotional experiences to boost recognition of own-race faces.
有证据表明，男性和女性在对情感面部表情的感知上存在差异。然而，之前的研究均未直接调查在处理本族和其他种族面孔的情绪时的性别差异。本研究使用高时间分辨率的事件相关电位技术解决了这一问题。总共分析了25名参与者（13名女性和12名男性）的数据。研究发现，与右侧半球电极上的负面中国人面孔相比，女性对负面白人面孔的N170波幅增加。这一结果表明，女性对表现出负面情绪（恐惧或厌恶）的其他种族面孔更为敏感，这可能有助于进化。然而，当前数据显示，男性在左侧半球电极上对快乐的中国人面孔比对快乐的白人面孔的N170波幅增加，这表明男性对表现出积极情绪（快乐）的本族面孔更为敏感。在这方面，男性可能利用过去愉快的情感经历来提高对本族面孔的识别。
