The purpose of this study is to explore whether subjects exposed to stimuli of facial expressions respond with facial electromyographic (EMG) reactions consistent with the hypothesis that facial expressions are contagious. This study further examines whether males and females differ in facial EMG intensity. Two experiments demonstrated that subjects responded with facial EMG activity over the corrugator supercilii, the zygomatic major, the lateral frontalis, the depressor supercilii, and the levator labii muscle regions to stimuli of sad, angry, fearful, surprised, disgusted and happy faces, that, to large extent, were consistent with the hypothesis that facial expressions are contagious. Aspects of gender differences reported in earlier studies were found, indicating a tendency for females to respond with more pronounced facial EMG intensity.
本研究的目的是探讨暴露于面部表情刺激的受试者是否会产生与面部表情具有传染性这一假设相一致的面部肌电图（EMG）反应。本研究进一步考察男性和女性在面部EMG强度上是否存在差异。两项实验表明，受试者在皱眉肌、颧大肌、额外侧肌、降眉肌和提上唇肌等肌肉区域对面部悲伤、愤怒、恐惧、惊讶、厌恶和高兴表情的刺激产生面部EMG活动，这在很大程度上与面部表情具有传染性这一假设相一致。研究发现了早期研究中报道的性别差异方面的情况，表明女性有以更明显的面部EMG强度做出反应的倾向。
