Previous studies, mainly with Caucasian samples, have shown that facial expressions of emotion are contagious, a phenomenon known as facial mimicry. This study examined facial mimicry using a Japanese sample. Participants were shown a series of Japanese faces (from Matsumoto and Ekman, 1988) on a computer screen expressing "happiness", "sadness", "anger", or "disgust". While viewing the facial expressions, electoromyograms (EMG) of the participants' faces were recorded to see whether their own facial muscles corresponding to the stimulus faces were activated. Consistent with the previous studies using Caucasian samples, all four facial expressions were mimicked. The peak time of mimicry of angry or happy faces was later, while that of disgusted faces was relatively sooner. The potential relation of facial mimicry to "emotional contagion", a social phenomenon whereby subjective feelings transfer between people, is discussed.
以往的研究主要以白人为样本，结果表明情绪的面部表情具有传染性，这一现象被称为面部模仿。本研究使用日本样本检验面部模仿。在电脑屏幕上向参与者展示一系列来自松本和埃克曼（1988年）的日本面孔，这些面孔分别表达“快乐”“悲伤”“愤怒”或“厌恶”。在观看面部表情时，记录参与者面部的肌电图（EMG），以观察他们与刺激面孔相对应的面部肌肉是否被激活。与以往使用白人为样本的研究一致，所有四种面部表情都被模仿了。愤怒或快乐面孔的模仿峰值时间较晚，而厌恶面孔的模仿峰值时间相对较早。本文还讨论了面部模仿与“情绪感染”（一种主观感受在人与人之间传递的社会现象）之间的潜在关系。
