Abstract
According to a study of Situated Cognition, learning for individuals is not valid until they join into practice and acquire their own roles under the social environment. We call such a capability “sociality”, a capability of finding its own role or niche in the social environment through interactions with their restricted neighbors. Our main purpose in this paper is to clarify an emergent mechanism of such “sociality” from the viewpoint of a multiagent study. In this paper, we emphasize that the emergence of “sociality” seems to depend on the dual capabilities of an individual's referencing; self-referential and social-referential abilities. In addition, we present a learning model of an agent having such dual capabilities as a Bi-Referential Model, in which each referencing capability is implemented by an evolutionary computation method of classifier system. Finally we present simulation results obtained by the proposed Bi-Referential Model and discuss the relation between the emergent process of “sociality” and the changes of resources that are commonly available to the agents.
