摘要: 自动探测面孔情绪的变化对个体生存是十分重要的。许多采用事件相关电位(ERP)技术的研究表明情绪失匹配负波(EMMN)可以作为检测面孔情绪自动加工的指标。前人的研究表明偏差-标准刺激对(不同/相同)和情绪类型(消极/积极)影响了EMMN效应,但是结论存在争议。本研究对36项以EMMN为指标的研究(共733名被试)进行元分析,结果表明:(1)在早期(0 - 200ms)和晚期(200 - 400ms)都发现了显著的EMMN效应,偶然呈现的情绪性面孔在两个时间窗内诱发更负的ERP,表明EMMN反映了面孔情绪相关的早期和晚期ERP成分的概率效应;(2)偏差-标准刺激对类型调节了早期而不是晚期EMMN效应:在早期区间内,不同的偏差-标准刺激对诱发了更大的EMMN;(3)在相同偏差-标准刺激对的研究中,等概率和非等概率的EMMN效应在两个时间窗内都没有显著差异;(4)早期和晚期EMMN都具有消极偏向,即,消极情绪诱发的EMMN显著大于积极情绪诱发的EMMN。这些结果表明,EMMN效应受到偏差-标准刺激对和情绪类型等实验变量的影响。

Abstract: The automatic detection of facial emotion changes is crucial for survival. Numerous studies using event-related potential (ERP) technique have found that the amplitude of emotion-related visual mismatch negativity (EMMN) could be used to test the automatic processing of facial emotion. Previous studies suggested that deviant – standard stimulus (D-S) pair (different/ same) and emotion type (negative/ non-negative) might modulate the EMMN effect, however, the evidence so far was mixed. Therefore, we conducted a meta-analysis to analyze the findings of 36 studies (involving 733 healthy participants) on EMMN. Results showed that: (1) EMMN effects emerged at both the early- (0 – 200ms) and late- (200 – 400ms) stages, demonstrating that infrequently presented deviant stimulus elicited more negative ERPs at both the early- and late-stages. This suggests that EMMN reflects the probability effect of early- and late-stages emotion-related ERP components; (2) the type of D-S pair moderated the EMMN effect at the early- but not the late-stages. Specifically, the EMMN effect of different D-S pairs was significantly larger than that of the same D-S pairs at the early-stage; (3) in the studies of same D-S pairs, the evidence between equiprobable and non-equiprobable paradigm showed no significant differences in EMMN at both stages; (4) a negative bias was found in both early and late EMMN, i.e., the EMMN elicited by the angry, fearful, angry faces was significantly larger than that of happy faces. These results indicate that the EMMN effect is affected by experimental manipulations such as D-S pair type and emotion type.
