Abstract(in Japanese) (See Japanese page)
Abstract(in English) Rapid Facial Reactions (RFR) are a phenomenon that matches facial expressions when seeing others’ expressions. Motion mimicry hypothesis assumes that RFR is an effect of automatically imitating the facial movements of others, while appraisal theory assumes RFR as a preliminary step of recognizing other’s expressions. As the relationship between the two models has been unknown, we aimed to examine the RFR for stimuli that show different emotions in the upper and lower parts of the face. The activity of the corrugator supercilii muscle corresponding to the eyebrow furrowing movement during anger emotion expression supported the appraisal theory, while the activity of the zygomaticus major muscle, which corresponds to the movement of raising the corners of the mouth, supported the motor imitation hypothesis. The results indicated that different models could explain the mechanism of RFR in different parts of facial muscles.
