| Research Abstract |
We explored psychological and neural underpinnings of human social interaction, by conducting behavioral (e.g. gaze cueing and recognition of dynamic facial expressions of emotion) and neuroimaging studies (fMRI). Neuroimaging studies were carried out to investigate brain activities while viewing dynamic facial expressions. The results revealed that the broad region of visual cortices, the amygdala, and the right inferior frontal gyrus were more activated in response to dynamic facial expressions than control stimuli, such as static facial expressions and dynamic mosaics. In corresponding with the characteristics of these brain activities, the results of psychological studies indicated that the dynamic presentation : (a) intensified the perceptual image of the facial expression (perceptual enhancement), (b) enhanced the emotional feeling ; and (c) elicited spontaneous and rapid facial mimicry. These results revealed that the dynamic property facilitates the perceptual, emotional, and motor processing of facial expressions of emotion. We also conducted cross-cultural studies using "Reading-mind-from-the-eyes" using both original Caucasian version and Asian version. We found the own-race-bias effect both in the United States and in Japan.
