◆Research Interests
Constructive study on knowledge from evolutionary viewpoint: The origin and the evolution of language and the formation and change of institutions
I am interested in complex systems, especially, the dynamics of language and society. My recent research focuses on the origin and the evolution of language. Currently, I’m studying the cognitive modelling of grammaticalisation, which is language change from contents words, such as nouns and verbs, to functional words, such as pronouns and auxiliaries. Grammaticalisation is said to be a key phenomena concerning the evolution of language. The cognitive modelling of the phenomena may shed a new light on the origin of language as well as its evolution. 備考
Dynamics of Symbolic Communication
Symbolic communication consists of interchanging of symbols among individuals and sense-making of the symbols in each individual. During communication novel meanings and symbols may occur, as well as sharing of information and meanings. Namely, communication is a process of sharing and creation. In order to understand such underling structure of such dynamic communication, we are engaging in constructive study using computer simulation, cognitive experiments, and analysis of mathematical models. 備考
