Title : Dynamics and Logic for Understanding Cognition and Behavior of Human 1997.12.15 (Mon) --- 1997.12.17 (Wed) Organizer : Takashi Ikegami, Yasuo Kuniyoshi, Ikuro Konishi, Masato Taichi, Gentaro Taga, Jun Tani, Takashi Hashimoto Contents : In attacking the hard problems of human cognition and behavior, it is quite important to consider by which way we might be able to gain our understanding of these problems. Although observations of human phenomena in physiological or psychological levels could show a rich collections of facts to the observers, it is sometime difficult to extract the essential mechanisms from them. On the other hand, we sometime feel that we could understand the basic mechanisms just by proposing a rigorous theoretical model. We, however, recognize later the existence of a large gap between the theory and the reality in many cases. It is natural to say that the hard problems of cognition and behavior cannot be attacked by using any single methodology. Through a decade of complex systems researches, we have learned that complex phenomena in natural as well as social systems could be better understood in the cross sections of multi-disciplinary views. We assume that multi-disciplinary is a key also to access our problems. Our workshop invites the discussions from the diverse approaches including observations of brain and motor behavior in physiological and psychological levels, mathematical modeling using dynamical systems and logic, constructivist approach such as building robots. We attempt to seek a novel approach for the problems through such discussion.
