【摘要】：目的:本研究采用事件相关电位(ERPs)技术考察个体对不同情绪变化的本族和异族面孔识别。方法:本研究采用S1-S2范式,让20名大学生被试观看三种情绪变化的视频并判断前后两段视频中的人是否是同一个人,通过ERP技术来采集他们的脑电活动。结果:(1)行为结果显示,被试可以更准确地识别负性情绪变化的面孔,这说明知觉者表现出对负性情绪变化的识别偏向。(2)ERP研究结果显示,与异族面孔相比,本族面孔诱发了较长的P100和P200潜伏期。重要的是,在大脑的右半球,负性情绪变化条件下的异族面孔所诱发的N170波幅显著高于本族面孔所诱发的波幅。结论:个体对负性情绪的异族面孔比本族面孔更敏感,这说明个体会认为负性情绪的异族面孔比本族面孔更具有威胁性。
[Abstract]:Aim: to investigate the face recognition of individuals with different emotional changes by event-related potentials (ERPs). Methods: using S1-S2 paradigm, 20 college students were asked to watch the video of three mood changes and determine whether the person in the video was the same or not, and to collect their EEG activity by ERP technology. Results: the behavioral results showed that the subjects could more accurately identify the faces with negative emotional changes, which indicated that the perceptors showed a bias of recognizing negative emotional changes. The results of ERP showed that compared with the faces of different ethnic groups, the subjects showed a tendency to recognize the changes of negative emotions. The long latency of P 100 and P 200 was induced by the faces of this nationality. Importantly, in the right hemisphere of the brain, the N170 amplitude induced by the negative emotional changes is significantly higher than that induced by the native faces. Conclusion: individuals are more sensitive to the faces of negative emotions than the faces of their own, which indicates that the faces with negative emotions are more threatening than the faces of their own.
