The relationships between facial mimicry and subsequent psychological processes remain unclear. We hypothesized that the congruent facial muscle activity would elicit emotional experiences and that the experienced emotion would induce emotion recognition.
METHODOLOGY/PRINCIPAL FINDINGS: To test this hypothesis, we re-analyzed data collected in two previous studies. We recorded facial electromyography (EMG) from the corrugator supercilii and zygomatic major and obtained ratings on scales of valence and arousal for experienced emotions (Study 1) and for experienced and recognized emotions (Study 2) while participants viewed dynamic and static facial expressions of negative and positive emotions. Path analyses showed that the facial EMG activity consistently predicted the valence ratings for the emotions experienced in response to dynamic facial expressions. The experienced valence ratings in turn predicted the recognized valence ratings in Study 2.
These results suggest that facial mimicry influences the sharing and recognition of emotional valence in response to others' dynamic facial expressions.
面部模仿与后续心理过程之间的关系尚不清楚。我们假设，一致的面部肌肉活动将引起情绪体验，而体验到的情绪将引起情绪识别。
方法/主要发现：为了检验这一假设，我们重新分析了之前两项研究的数据。我们记录了皱眉肌和颧大肌的面部肌电图（EMG），并在参与者观看动态和静态的负性和正性面部表情时，对体验到的情绪（研究 1）和体验到的和识别到的情绪（研究 2）的效价和唤醒程度进行了评分。路径分析表明，面部 EMG 活动一致地预测了对动态面部表情做出反应时所体验到的情绪的效价评分。体验到的效价评分反过来又预测了研究 2 中识别到的效价评分。
这些结果表明，面部模仿影响了对他人动态面部表情的情绪效价的分享和识别。
