Outline of Final Research Achievements

The purpose of this study is to understand the dynamics of biological/cultural evolution of cooperation, and its application. First, we showed that direct and indirect reciprocity operate cooperatively preventing defective individuals form invading. Second, using a web-based experimental framework for dynamic and cooperative social relationships with real-time decision-making and rewarding environment, we showed that psychological characters of players might reflect their behavioral characteristics in the game. Third, our statistical analysis of players behavior in a social networking game showed that communication with a rather significant cost tends to lead to cooperation. Fourth, we presented a conceptual platform of gamified system with a dual layer structure, which was shown to promote reciprocity-based cooperation in targeted social contexts.
