Research Abstract

This study, with a series of functional brain imaging experiments, clarified neural substrates of sustaining interest in a human-agent interaction (HAI), and developed techniques for online monitoring of brain functions and designing new framework for sustainable HAI. More specifically, (1) it clarified that cognitive engagement or "readiness" can be decoded from slow spontaneous neural dynamics, (2) it identified neural bases of cognitive and motivational dynamics that are important for sustainable HAI, and (3) it established that the engagement in natural human communication is reflected in inter-individual relationships between neural activities of communicating individuals.
