Show moreThree preregistered experiments examined to what extent information about an epidemic situation provided by experts and information about anti-infection policies promoted by governments/media influenced anti-infection behaviors. The above effects were examined among populations from different countries (in Experiments 2 and 3) and across self-construals (in Experiment 3). In three experiments, participants (N =706) were presented with a scenario where experts provided (or did not provide) information about an epidemic situation and governments/media promoted (or did not promote) information about anti-infection policies. After that, participants indicated their willingness to adopt anti-infection behaviors. Results across three experiments showed that both types of information independently increased participants’ anti-infection behaviors. In Experiments 2 and 3, we further found that the epidemic information had a larger impact on inducing anti-infection behaviors than the policy information, which was robust and consistent across countries and self-construals. Findings were discussed under the framework of social influence and in terms of practical implications for pandemic situations like the COVID-19. Show less

Show moreThis thesis examined the extent to which relationships between emotional experiences and aggressive behaviours in adolescents are affected by culture. While existing studies often compare individuals from different countries to study cultural influences, this thesis also took a between-country approach by comparing Dutch and Malaysian adolescents; groups that reflect individualistic and collectivistic cultures, respectively. Also, the effect of individualistic and collectivistic values at an individual level was examined. First, the outcomes show that many relationships were culturally universal. Regardless of country or cultural orientation, adolescents who had more problems with anger control tended to be more aggressive; and those who experienced intense anger, fear and shame were more often bullied. Also, guilt was related to less aggressive behaviours in both Malaysian and Dutch samples. Yet, this thesis also revealed country/cultural specific relationships. Whereas shame was related to more aggression in Dutch adolescents, the opposite was true for Malaysian adolescents.Remarkably, this thesis found that the traditional classification between individualistic Western countries and collectivistic Eastern countries was not fully supported when cultural values were assessed at individual levels. For example, while higher levels of shame were related to less aggressive behaviours in individualistic-oriented adolescents, the opposite was true for collectivistic-oriented adolescents. Show less

Show moreBiologists and social scientists have long tried to understand why some societies have more fluid and open interpersonal relationships and how those differences influence culture. This study measures relational mobility, a socioecological variable quantifying voluntary (high relational mobility) vs. fixed (low relational mobility) interpersonal relationships. We measure relational mobility in 39 societies and test whether it predicts social behavior. People in societies with higher relational mobility report more proactive interpersonal behaviors (e.g., self-disclosure and social support) and psychological tendencies that help them build and retain relationships (e.g., general trust, intimacy, self-esteem). Finally, we explore ecological factors that could explain relational mobility differences across societies. Relational mobility was lower in societies that practiced settled, interdependent subsistence styles, such as rice farming, and in societies that had stronger ecological and historical threats.

Show moreMuch of the previous work investigating the impact of honor on conflict management has focused on how people endorsing honor values respond to possibly offensive interactions. Despite the accumulation of this research, it is yet unclear why people endorsing the ideal of honor respond more fiercely after being offended. Moreover, hardly any systematic attempts have been undertaken to identify ways in which these negative ramifications of offensive encounters can be prevented or reduced. The discoveries made in the context of this dissertation paint a more balanced picture of the effect of honor concern on conflict management and inform us on possible avenues of effective conflict intervention.
