Culture and cooperation: Examination of US-Japan differences in the framework of uncertainty avoidance
The objective of this thesis was to examine whether uncertainty avoidance dimension of culture produces Unites State-Japan differences in cooperative behavior. I examined how uncertainty operated to produce cooperative behaviors differently between American and Japanese subjects. The subjects' cooperative behaviors were observed during the ultimatum game. Individual differences in individualism-collectivism, intolerance of uncertainty, and neuroticism were also measured as potential mediators or covariates of the effect of uncertainty and country on the cooperative behavior. Data showed that although there was no cultural difference on cooperative behaviors between Americans and the Japanese, uncertainty generally increased cooperative behaviors across cultures. The individual-level analysis also demonstrated that the Japanese had higher intolerance of uncertainty than did Americans. This thesis suggests that the uncertainty avoidance dimension is a useful cultural framework to explore cultural differences between Americans and Japanese in various domains of behaviors.
