In face-to-face conversations, when asking questions, the onset of eyebrow movements usually comes earlier than the speech. What is the role of the precedence of the eyebrow movements? 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 in 16th annual meeting of Society for the Neurobiology of Language in title of “The impact of conversational eyebrow movements on intention recognition: An fMRI Study” by Mr. Yuyong Liu, the student of Graduate School of Medicine.
This study is conducted in collaboration with the Interdisciplinary ICT Research Center for Cyber and Real Spaces, Tohoku University. (Sugiura)
