| Outline of Final Research Achievements |
In this research, we tried to find and developed an experimental paradigm which realize nearly natural interaction (i.e. real-time communication) between two people in the MR scanner. In parallel, we also extend narrowly defined joint attention to verbally-cued, object-based one, which investigated what is core neural mechanism of shared attention/intention during real social interaction. To compare the synchronization of the brain activity between real pairs and pseudo-pairs (non-pairs), we analyzed the residual time-courses data (i.e. subtracted task-related brain activity) during the interaction task. The results showed that brain activities in the right tempolo-parietal junction (rTPJ), right superior temporal sulcus (rSTS), and dorso-medial prefrontal cortex (dmPFC), were more synchronized between the real pairs than between the non-pairs. It indicates that these synchronized regions might form a common psychological ground to progress a cooperative interaction task smoothly.
