The method of event-related potentials (ERP) was used to study the gender difference in face recognition. The stimuli in the experiment were 10 upright and 10 inverted face photos. The subjects, half female and half male, were asked to judge whether the face was upright or inverted. The results showed that the N170 wave forms were observed in the occipito-temporal regions and they were found exhibiting brain's right hemispheric dominance. The stimuli of different gender photos were noticed to have no significant impact on the N170 wave forms, but there were significant differentce in the amplitude and latency period of N170 between different gender participants. Moreover, there was marked difference in the latency period of the male participants watching the same gender face and different gender face. Similar results were not found in the ERP's latency period of female participants.
采用事件相关电位（ERP）方法研究人脸识别中的性别差异。实验刺激为10张正立和10张倒立的面部照片。受试者男女各半，被要求判断面部是正立还是倒立。结果显示，在枕颞区观察到N170波形，且发现其表现出大脑右半球优势。不同性别照片的刺激对N170波形没有显著影响，但不同性别参与者之间N170的波幅和潜伏期存在显著差异。此外，男性参与者观看同性和异性面部时潜伏期存在显著差异。女性参与者的ERP潜伏期未发现类似结果。
