In face-to-face conversations, the onset of conversational facial signals usually comes earlier than the speech. What is the role of the precedence of facial signals? The present study created videos where the timing of facial signals and speech is manipulated and let participants watch the videos in the MRI. The results reveal that he precedence of facial signals helps to efficiently predict speakers’ intentions based on facial motion perception, and that people who are more responsive to others show more sensitivity to the timing of facial signals. It was presented by Mr. Yuyong, the student of Graduate School of Medicine in 53rd SfN annual meeting in title of “The Role of the Precedence of Conversational Facial Signals in Understanding Intentions: an fMRI study ”.
This study is conducted in collaboration with the Interdisciplinary ICT Research Center for Cyber and Real Spaces, Tohoku University.(Sugiura)
