Disaster myths after the Great East Japan Disaster and the effects of information sources on belief in such myths. 
東日本大震災後の災害神話：神話への「信仰」に情報源が及ぼす効果
Disasters, 38(s2), s190-s205.
doi: 10.1111/disa.12073/

This study examines how well disaster myths were rooted in Japanese people after the Great East Japan Disaster, as well as the effects of information sources on these misconceptions. Five common disaster myths are covered (panic, psychological shock, looting, increases in the crime rate, and material convergence), and information sources were divided into two types: public and private. Three hundred participants were asked how much credit they would give the five myths and which information sources they would rely on in post-disaster situations. The results found that, as in Western societies, these disaster myths do exist among Japanese people. Also, only public sources of disaster information, such as television and Internet news websites, had some effect on the degree of belief in disaster myths, while private sources, such as one’s family, friends, and social networking sites, did not. Factors affecting the degree to which people believe in disaster myths are also discussed.

The Effects of Social Ties and Local Environment on Appropriate Waste Station Maintenance of Household Waste: A Case Study in Sapporo.
家庭ゴミ捨て場の適切な維持に対する社会的紐帯と地域環境の影響：札幌市の事例研究
Journal of Environmental Information Science, 44(5), 87-98.

“Waste stations”, where residents dispose of household waste, are usually maintained by the residents themselves; however, not all stations are well maintained. It was hypothesized that the level of waste station maintenance would correlate with the degree of social ties in the community, and would be influenced by local environment in the area around the waste station. A combination of observational and survey research methods were employed to test these hypotheses. Self-reported inappropriate disposal behavior and social ties were measured using a questionnaire survey, while the level of maintenance of waste stations and local surrounding environment were recorded using observational methods. Data from 508 residents, assigned to 102 waste stations in 23 local areas of Sapporo, Japan, were analyzed. Sequential regression analysis indicated that social ties in the community was the stronger predictor of the management level of waste station than the self-report disposal behavior. Furthermore, multi-level model tests revealed that the level of management of waste stations was predicted by the local surrounding environment, which provided spatial reminders of community interactions. This indicates that managing the local surrounding environment is an important intervention to encourage appropriate waste station management

Effects of voice and similarity on procedural fairness and trust: A dual process model of public acceptance based on representatives’ participation.
手続き的公正と信頼に対する声と類似性の効果
Asian Journal of Social Psychology, 18(3), 216-224.
doi: 10.1111/ajsp.12097

In citizen participation, a few representatives of the total citizen population participate in discussions with authorities regarding public decisions and policies. The present study examines a dual process model in which the representatives’ voice and similarity of values facilitate public acceptance through procedural fairness and trust in representatives, respectively. The results of an experiment employing a scenario method, which included participants from Japan (n = 211) and the Netherlands (n = 200), indicate that the representatives’ voice increased procedural fairness and public acceptance when the similarity of representatives was high. The effects of representatives’ voice on public acceptance via procedural fairness was supported in both nations, while other effects of representatives’ similarity on acceptance via trust were indicated only in Japan. These results suggest that the indirect voice of citizens, as conveyed by representatives, plays an important role in increasing perceptions of procedural fairness and public acceptance among citizens.

Effects of labeling and group category of evaluators on evaluations of aggression. 
攻撃の評価に対するラベリングと評価者の集団カテゴリの効果
PLoS ONE, 10(12): e0144384.
doi: 10.1371/journal.pone.0144384

This study investigated whether the effect of labeling on people’s evaluation of aggression varies according to the group category of the evaluators (i.e., whether they are ingroup members or third parties). Two labeling strategies—the negative labeling of victims (NL strategy) and the positive labeling of aggressors (PL strategy)–were adopted. We conducted an experiment using the hot sauce paradigm, as a way to assess aggressive intent that includes behavioral measures of evaluations. The results suggested that the NL strategy causes ingroup members to evaluate aggression in a more positive light, while the PL strategy has the same effect but on third parties instead. Thus, labeling strategies may increase the severity of aggressors’ reaction and could also be a factor that can escalate a war or conflict.

Educational attainment, time preference, and health-related behaviors: A mediation analysis from the J-SHINE survey.

Evidence consistently shows that low education is associated with unhealthy behaviors. A recent study in behavioral economics argued that high time preferences – the tendency to prefer immediate gain to later reward – explain the limited self-control of individuals in making preventive health-related choices. The aim of this study was to examine the mediating effect of time preference on the associations between education and smoking, binge drinking and overweight in young and middle-aged adults living in a Japanese metropolitan area, using a quantitatively measured time discount rate. A population-based probabilistic sample of residents of 25–50 years of age living in four municipalities within Japanese metropolitan areas where economic disparity is relatively large was obtained from the Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE). Respondents answered the questionnaire items using a computer-aided personal instrument (CAPI). Data from 3,457 respondents were used in this study. Time preferences measured as categorical responses were converted into a continuous number of time discount rates by using the maximum likelihood method. Smoking habit, binge drinking, and body mass index were regressed on educational attainment with demographics and other confounders. The mediating effects of the time discount rate were examined with the bootstrapping method. Results showed that the time discount rate did not mediate the association between education and binge drinking and BMI. Even for smoking, the mediating effect of time discount rate was quite limited, indicating that the proportion of total effect of education mediated was only 4.3% for men and 3.0% for women. The results suggest that modifying time preferences through educational intervention has only limited efficacy in closing disparities in health-related behaviors, and that other mediators fostered by schooling, such as knowledge/skills, group norms and supportive peers/networks, may be more important as modifiable mediators in the link between education and smoking.

The rural–urban difference in interpersonal regret.
対人的後悔における田舎の都会の違い
Personality and Social Psychology Bulletin, 42(4), 513-525.
doi: 10.1177/0146167216636623

The present research examined rural–urban differences in interpersonal regret. In Study 1, participants who grew up in rural areas reported stronger interpersonal regret than those who grew up in large cities. In Study 2, we conducted an experiment and found that participants who were assigned to imagine a rural life reported greater interpersonal regret than those who were assigned to imagine an urban life. Moreover, this rural–urban difference was mediated by the degree to which participants wrote about informal social control such as gossip and reputation concerns. Finally, in Study 3, we used the pictorial eye manipulation, which evokes a concern for informal social control, and found that participants from large cities who were exposed to the eyes reported more intense interpersonal regret than those who were not exposed to the eyes. Together, these studies demonstrate that informal social control is a key to understanding rural–urban differences in interpersonal regret.
