研究了被试在执行快速序列视觉呈现（RSVP）任务时面部表情加工的电生理相关性。事件相关电位（ERP）成分P1、顶点正电位（VPP）和N170的峰值潜伏期分别为165、240和240 ms。早期前N100和后P1振幅引起的恐惧的面孔比引起的快乐或中性的面孔，这一发现是一致的存在的“负性偏见”。当受试者处理恐惧和快乐的面孔时，前VPP的幅度大于处理中性面孔时的幅度;对恐惧和快乐面孔的反应相似。晚期N300和P300不仅区分了情绪面孔和中性面孔，而且区分了lag 2中的恐惧和快乐表情。注意资源对N100、VPP、N170、N300和P300成分的振幅和P1成分的潜伏期有调制作用。注意资源不足导致ERP各成分波幅降低、潜伏期延长。根据这些结果，我们提出了一个假设的模型，涉及三个阶段的面部表情处理。
Electrophysiological correlates of the processing facial expressions were investigated in subjects performing the rapid serial visual presentation (RSVP) task. The peak latencies of the event-related potential (ERP) components P1, vertex positive potential (VPP), and N170 were 165, 240 and 240 ms, respectively. The early anterior N100 and posterior P1 amplitudes elicited by fearful faces were larger than those elicited by happy or neutral faces, a finding which is consistent with the presence of a ‘negativity bias’. The amplitude of the anterior VPP was larger when subjects were processing fearful and happy faces than when they were processing neutral faces; it was similar in response to fearful and happy faces. The late N300 and P300 not only distinguished emotional faces from neutral faces but also differentiated between fearful and happy expressions in lag2. The amplitudes of the N100, VPP, N170, N300, and P300 components and the latency of the P1 component were modulated by attentional resources. Deficient attentional resources resulted in decreased amplitude and increased latency of ERP components. In light of these results, we present a hypothetical model involving three stages of facial expression processing.
