People react with Rapid Facial Reactions (RFRs) when presented with human facial emotional expressions. Recent studies show that RFRs are not always congruent with emotional cues. The processes underlying RFRs are still being debated. In our study described herein, we manipulate the context of perception and its influence on RFRs. We use a subliminal affective priming task with emotional labels. Facial electromyography (EMG) (frontalis, corrugator, zygomaticus, and depressor) was recorded while participants observed static facial expressions (joy, fear, anger, sadness, and neutral expression) preceded/not preceded by a subliminal word (JOY, FEAR, ANGER, SADNESS, or NEUTRAL). For the negative facial expressions, when the priming word was congruent with the facial expression, participants displayed congruent RFRs (mimicry). When the priming word was incongruent, we observed a suppression of mimicry. Happiness was not affected by the priming word. RFRs thus appear to be modulated by the context and type of emotion that is presented via facial expressions.

在不一致语境中抑制负面表情的面部模仿

当人们表现出人的面部表情时，他们会做出快速的面部反应（RFR）。最近的研究表明，RFR并不总是与情感暗示相吻合。RFR的基础流程仍在争论中。在本文描述的研究中，我们操纵感知的上下文及其对RFR的影响。我们使用带有情感标签的潜意识情感启动任务。记录面部肌电图（EMG）（额叶，波纹板，骨和压抑物），而参与者观察到静态面部表情（欢乐，恐惧，愤怒，悲伤和中性表情）的前/下没有潜意识单词（欢乐，恐惧，愤怒） ，饱和度或中性）。对于否定的面部表情，当启动词与面部表情一致时，参与者显示一致的RFR（模仿）。当启动词不一致时，我们观察到模仿的抑制。幸福不受启动词的影响。因此，RFR似乎受到通过面部表情呈现的情绪的上下文和类型的调节。
