Research Interests:

My research has focused on understanding the adaptive value of culture-specific behaviors. The research projects I have undertaken are detailed below.

- Culture-specific Behavior as Adaptive Strategy: It is reasonable to hypothesize that culture-specific behaviors have adaptive value for those living in societies. In collectivist societies, (e.g., Japan) in which groups are typically closed to outsiders, those who are excluded from their groups have difficulty finding alternative groups that will accept them. The cost of being excluded, therefore, is much higher in collectivistic societies than in individualistic societies (e.g., the USA) in which individuals can more easily replace lost relationships. Indeed, we have already demonstrated that some culture-specific behaviors, often called ginterdependenth behaviors in cultural psychology, are highly ecological fit in terms of minimizing the risk of accruing a bad reputation (Hashimoto, et al., 2011; Yamagishi, et al., 2008; 2012).

- Two Distinct Aspects of gInterdependenceh: Harmony seeking and rejection avoidance: From the adaptationist perspective, social order in collectivistic societies is thought to be maintained through mutual monitoring and threats of exclusion from social relations. In such societies, the avoidance of being disliked and excluded by close relatives is critical for survival and success. In contrast, in individualistic societies in which social order depends less on mutual monitoring and more on a democratic legal system, the need to avoid being disliked by close relatives is weaker. In light of these differences in the mechanism of maintaining social order, cultural differences in the levels of rejection avoidance, but not in the levels of harmony seeking, between collectivistic and individualistic societies can be predicted. We are now examining this assumption, and this assumption has been supported by a study comparing people from Japan and the USA (Hashimoto & Yamagishi, 2013).

- Dual Roles of Culturally Shared Beliefs: Culturally shared beliefs play dual roles in affecting peoplefs behavior; i.e., shared beliefs create culturally installed goals and affect the expected responses of others. The former has been a focus of the standard approaches to culture in psychology. For example, cultural psychologists have successfully delineated how culturally shared beliefs that promote independence or interdependence affect peoplefs perceptions or behavior. The success of these studies, however, seems to have had the unintended effect of restricting the use of other approaches to analyze how culturally shared beliefs shape the way that people construct reality. I am now undertaking research that focuses on the latter, that is, the expected responses of others. Specifically, I have shown that Japanese people revealed their preference for independence over interdependence, while they expected that others would prefer interdependence to independence (Hashimoto, 2011; 2012). We have also shown that American and Japanese participants rated the independent target as more desirable than the interdependent target. However, Japanese participants expected that others would regard the interdependent target more positively than the independent target. Our results suggest that the culturally shared Japanese beliefs that interdependent persons receive more positive evaluations than independent persons creates incentives for Japanese people to behave interdependently regardless of their personal preferences (Hashimoto & Yamagishi, submitted)
