Outline of Final Research Achievements

In this study, we have attempted to depict "atmosphere of cooperative work" defined as the mutual influence of collaborators in the operation of a large-scale system through simultaneous biological measurements among multiple participants. The result revealed that interpersonal neural synchronization fluctuates with the presence of others even in the absence of explicit communication. In addition, in a collaborative task using simultaneous measurement of brain activity and pupil diameter, it was observed that interpersonal neural synchronization and pupil diameter fluctuated separately, reflecting the degree of engagement of the workers in the collaborative task and the existence of a direct cooperative relationship during the task. These results indicate that biological measurements of brain activity and pupil diameter can be used to visualize the "atmosphere of cooperative work".

Academic Significance and Societal Importance of the Research Achievements

非侵襲・低拘束な生体計測手法により「場の空気」を推定する本研究成果は、計測機器の小型化などハードウェア面での課題は残されているものの、作業現場での応用が期待できる。また社会神経科学の観点からも、本研究では明示的なコミュニケーション時の脳活動同調に加えて、暗黙の他者相互作用による脳活動の揺らぎを明らかにしており、他者意識の神経機序を解明する上での重要な知見を得ることができた。
