My research interest is to reveal possible changes of cognition/behaviour at current circumstances using concepts such as self-organization and critical phenomena. Those are investigated at various levels of abstracted experiences from psychology (subjective) to physics (objective). We conduct cognitive/behavioural experiments of human and animals as well as mathematical modeling to make the mechanisms clear. Outcomes from our researches are expected in system developments to merge organisms and information technology.  Natural-born Intelligence (天然知能), a theory of  living system attracting outside of perceivable world [proposed by Yukio-Pegio Gunji], is the keyword.
