摘要：

面部表情加工的ERP成分主要包括P1 (80~120 ms)、N170 (120~200 ms), 早期后部负电位(Early Posterior Negativity, EPN, 200~300 ms)和晚期正成分(Late Positive Potential, LPP, 300 ms以后)。这些成分代表了表情加工的不同阶段, 具有不同的心理含义。P1成分只对威胁类表情(恐惧, 厌恶和愤怒)敏感, 反映了对威胁面孔的快速探测, 具有自动加工的性质。N170成分与表情结构信息的编码有关, 同样具有自动加工的性质。EPN反映了对情绪信息的选择性注意, 具有情绪普遍性, 情绪场景图片和表情刺激都会对它产生影响, 在特定的条件下具有自动加工的性质。LPP则反映了对情绪信息的高级认知加工, 较易受注意控制的影响。在对上述成分的特性了解的基础上, 将来的研究应该探索以下问题：(1) P1是否受表情威胁程度的影响？(2) N170受到哪些自上而下因素的影响？(3)那些不能影响N170成分, 却能影响EPN成分的表情刺激是否被当成了普通的情绪刺激来看待？(4)表情加工引发的LPP是否能具有自动加工的性质？(5)不同的基本表情类型(如恐惧和厌恶)是否具有特异性的ERP成分？

Abstract:

The ERP components related to facial expression processing include P1 (80~120 ms), N170 (120~200 ms), EPN (Early Posterior Negativity, 200~300 ms) and LPP (Late Positive Potential, after 300 ms). These components represent different stage of facial expression process and thus have different mental meaning. P1 is sensitive to threaten-related face, such as fear, disgust and anger, reflects a quick and automatic detection to threatened stimuli. N170 implicates the automatic process to code the structure of expression. EPN reflects the selective attention to emotion information. This competent is also automatic in some conditions and can be modulated by emotional expression of different kinds and emotional scene. LPP that is affected by attention control represents the higher cognitive process. Future research should extend the understanding of these ERP components by exploring: (1) Whether P1 is affected by the extent of threat. (2) The impact of top-down factors on N170. (3) Whether the facial expression stimulus that can elicit EPN, but not N170 be treated as general emotional stimulus. (4) Whether the LPP also reflects certain level of automaticity. (5) Whether processing different type of expression (e.g. fear and disgust) is dissociative in ERPs?
