Academic Particulars:

Tatsuya Kameda has degrees from the University of Tokyo (1982, 1984) in social psychology, and the University of Illinois at Urbana-Champaign (1989) in psychology. He taught at the University of Tokyo, Toyo University, and at Hokkaido University where he is currently Professor of Behavioral Science. He is Dirctor of the Center for the Sociality of Mind (CSM) at Hokkaido Unversity, which has been selected as one of the Global COE (Centers of Excellence) by the Japan Society for the Promotion of Science since 2007. He was a Fulbright Research Fellow (1997-1998) at the University of Colorado at Boulder (Department of Psychology) and Northwestern University (Department of Organizational Behavior), a Deutscher Akademischer Austausch Dienst Research Fellow (2001) at Max Planck Institute for Human Development in Berlin (Center for Adaptive Behavior and Cognition), and a Residential Fellow (2008-2009) at the Center for Advanced Study in the Behavioral Sciences (CASBS) at Stanford University.

Research Interests:

His research interests revolve around analyzing social behavior/cognition from the evolutionary/adaptationist perspective, through combining evolutionary games and agent-based simulations with behavioral experiments. Specifically, he is interested in how people handle social as well as environmental uncertainties collectively. Examples include research on development of a "communal-sharing norm" in primordial hunter-gatherer environments (Kameda, Takezawa, & Hastie, 2003, 2005; Kameda, Takezawa, Tindale, & Smith, 2002) and its potential linkage to our "fundamentally egalitarian minds" (Kameda, Takezawa, Ohtsubo, & Hastie, 2010), functions of social/cultural learning in a non-stationary uncertain environment (Kameda & Nakanishi, 2002, 2003), adaptive "fast and frugal" group decision heuristics (Hastie & Kameda, 2005; Kameda, Tsukasaki, Hastie, & Berg, 2011), collective risk-monitoring (Kameda & Tamura, 2007), and so on. He has also published a textbook in this research line (co-authored by Koji Murata), "Social psychology from a complex-system perspective: Humans as adaptive agents" (Tokyo: Yuhikaku, 2000). He is also interested in mathematical modeling of consensus formation processes in small groups on the one hand and decision/policy-making processes in organizations on the other (e.g., Kameda, 1997; Kameda, Tindale, & Davis, 2003). He has strong side interests in anthropology, biology, economics, political science, and law.
