Differences in national responses to COVID-19 have been associated with the cultural value of collectivism. The present research builds on these findings by examining the relationship between collectivism at the individual level and adherence to public health recommendations to combat COVID-19 during the pre-vaccination stage of the pandemic, and examines different characteristics of collectivism (i.e., concern for community, trust in institutions, perceived social norms) as potential psychological mechanisms that could explain greater compliance. A study with a cross-section of American participants (N = 530) examined the relationship between collectivism and opting-in to digital contact tracing (DCT) and wearing face coverings in the general population. More collectivistic individuals were more likely to comply with public health interventions than less collectivistic individuals. While collectivism was positively associated with the three potential psychological mechanisms, only perceived social norms about the proportion of people performing the public health interventions explained the relationship between collectivism and compliance with both public health interventions. This research identifies specific pathways by which collectivism can lead to compliance with community-benefiting public health behaviors to combat contagious diseases and highlights the role of cultural orientation in shaping individuals’ decisions that involve a tension between individual cost and community benefit.

Objective: Caring, sensitive parenting is known to be associated with higher levels of engagement in support-seeking behaviors among children and young adolescents. However, no study has yet explored the role of perceived parental attention in social support seeking in early adulthood. Growing evidence suggests that the µ-opioid receptor gene polymorphism (OPRM1 A118G) moderates one’s responsiveness to social environments. Prompted by the differential susceptibility theory of gene–environment interaction, the present study examined whether the OPRM1 polymorphism would moderate the association between perceived parental attention and social support seeking in early adulthood. Methods: Six hundred and twenty Japanese undergraduate students self-reported the amount of attention they subjectively perceived their parents to have given them during childhood and completed scales that assess support-seeking behaviors. Clippings of their fingernails were collected for genotyping. Results: The results showed that the interactive effect of perceived parental attention and OPRM1 genotypes on social support seeking was significant. Specifically, perceived parental attention only significantly and positively predicted OPRM1 GG carriers’ social support seeking in response to stress. Conclusions: The findings support the view that OPRM1 polymorphism moderates the association between early experiences and developmental outcomes.

Acting is closely related to theory of mind and empathy, which are fundamental abilities to maintain interpersonal relationships and facilitate cooperation among people. Acting experience intervention is known as one instrument to foster theory of mind and empathy; however, empirical evidence on the effects of brief acting experience in a laboratory setting remains scarce. To obtain further evidence to support the effects, we assigned 47 Japanese participants randomly to either an acting condition where they experienced a play in a group of three people in a 60-minute session or a control condition and measured their levels of theory of mind and empathy three times (one day before the intervention, soon after the intervention, and a week after the intervention). As expected, brief acting experience improved the level of empathic concern. However, no effect of acting was found in theory of mind and the other facets of empathy. Implications for future work in applied settings are discussed.

A single nucleotide polymorphism in the serotonin 2A receptor gene (HTR2A rs6311 guanine [G] vs. adenine [A]) appears associated with positive emotional contagion (social sharing of happiness) in Japanese people. However, it remains unknown whether the HTR2A polymorphism also impacts the social sharing of happiness in Western cultures. The present study thus compared 207 Japanese university students and 200 American adults (including non-students). Social sharing of happiness was examined using a vignette-based questionnaire. Participants were asked to imagine that they were experiencing an emotionally neutral event. At the same time, they were asked to imagine that a friend was experiencing a positive valence event (presence condition), whereas in the other condition such information was not presented (absence condition). Results showed that the G allele carriers felt happier in the presence than in the absence of the friend compared with participants with the AA genotype. Although we did not specifically consider comparability between the two samples, the findings suggest that the effect of HTR2A polymorphisms on social sharing of happiness observed in Japanese populations may be applicable to American populations.

This study investigated whether aspects of early life environment (quality of parental relationship, frequency of parental violence including disciplinary violence, amount of parental attention, and family income during childhood) would affect one's subjective well-being and loneliness later in life (i.e., during young adulthood). This study also investigated whether the negative influence of early life stress is greater among individuals with the SS genotype of the serotonin transporter-linked polymorphic region (5-HTTLPR) in the serotonin transporter gene. Participants were 568 university students whose genotypes were identified using nail samples. They reported their current levels of subjective well-being and loneliness as well as their recollections of their early family environments. The results showed that less stressful early life environments, such as high levels of parents' relationship quality and parental attention, were positively (negatively) associated with subjective well-being (loneliness), while frequent parental violence was negatively (positively) associated with subjective well-being (loneliness). Nevertheless, the gene × environment interaction effects were consistently non-significant—the SS genotype did not accentuate the effects of early life stress.

The current research examines cross-cultural differences in people’s daily stress experiences and the role of social orientations in explaining their experiences. Using a situation sampling method, Study 1 collected European Canadian and Japanese undergraduates’ examples of stressful interpersonal and non-interpersonal situations they experienced, measuring participants’ perception of the intensity and frequency of each type of situation. Studies 2 and 3 examined the effects of culture on participants’ reports of stress symptoms under the situations. Study 3 assessed the mediating effects of independence and interdependence between culture and perceived stress. These studies indicated that the situational context moderates the effect of culture on perceptions of stress, showing a different amount of stress from interpersonal situations between Japanese and European Canadian undergraduates. Mediational analyses revealed that independent orientation partially explains the relationship between culture and stress from interpersonal situations. The implications of these results for culture and daily stress are discussed.

This research investigated cross-cultural differences in strategic risky decisions in baseball—among professional baseball teams in North America and Japan (Study 1) and among baseball fans in the United States and Japan (Study 2—preregistered). Study 1 analyzed archival data from professional baseball leagues and demonstrated that outcomes reflecting high risk-high payoff strategies were more prevalent in North America, whereas outcomes reflecting low risk-low payoff strategies were more prevalent in Japan. Study 2 investigated fans’ strategic decision making with a wider range of baseball strategies as well as an underlying reason for the difference: approach/avoidance motivational orientation. European American participants preferred high risk-high payoff strategies, Japanese participants preferred low risk-low payoff strategies, and this cultural variation was explained by cultural differences in motivational orientation. Baseball, which exemplifies a domain where strategic decision making has observable consequences, can demonstrate the power of culture through the actions and preferences of players and fans alike.

Prior research has found that East Asians are less willing than Westerners to seek social support in times of need. What factors account for this cultural difference? Whereas previous research has examined the mediating effect of relational concern, we predicted that empathic concern, which refers to feeling sympathy and concern for people in need and varies by individuals from different cultures, would promote support seeking. We tested the prediction in two studies. In Study 1, European Canadians reported higher empathic concern and a higher frequency of support seeking, compared to the Japanese participants. As predicted, cultural differences in social support seeking were influenced by empathic concern. In Study 2, both empathic concern and relational concern mediated cultural differences in support seeking. Japanese with lower empathic concern but higher relational concern were more reluctant than European Americans to seek social support during stressful times. Finally, loneliness, which was more prevalent among the Japanese than among the European Americans, was partially explained by social support seeking.

Previous studies in population genetics have proposed that the Y-chromosomal (Y-DNA) haplogroup D ancestor likely originated from Africa. The haplogroup D branch next started Out-of-Africa migration, rapidly expanded across Eurasia, and later diversified in East Asia. Y-DNA haplogroup D-M55, one of the branches of haplogroup D, is only found in modern Japanese males, suggesting that individuals with Y-DNA haplogroup D migrated from the Eurasian continent. Based on previous observations, Y-DNA haplogroup D is expected to be associated with some male characteristics including personality. Therefore, this study investigated whether the Y-DNA haplogroup D-M55 is associated with several physiological and psychological characteristics, including exploratory motivation and human relationship-related perception. We recruited Japanese young adult males and females and investigated the association between Y-DNA haplogroup D-M55, physiological [body mass index (BMI)], and several psychological parameters [perceived number of close friends, behavioral inhibition system/behavioral activation system (BIS/BAS), perceived happiness, and perceived loneliness]. The results indicated that males with haplogroup D-M55 had a higher BMI and more close friends, compared with non-carrier males. Additional multiple regression analyses, which tested the hypothesis that haplogroup D-M55 predicts BMI and perceived number of close friends, confirmed our hypothesis, even after controlling for the potentially confounding variables of age and sex. We also analyzed the gene–gene interaction between haplogroup D-M55 and an autosomal gene polymorphism associated with BMI and human relationships, such as the dopamine D2 receptor gene (DRD2: rs1800497). Results showed gene–gene interactions between haplogroups D-M55 and DRD2 in BMI. Based on these findings, it is demonstrated that Y-DNA haplogroup D is associated with human personality.

Auditory images for speech are preserved and can be accessed during reading. This research, conducted in Japan, examined whether and to what extent previous findings on the influence of speaker-specific auditory images in reading can be generalized to non-English speakers in a different cultural context. In two studies, Japanese participants were asked to read a text aloud after being informed that the text had been written by either a fast speaker or a slow speaker whose speech they were to listen to. The participants read the episode more slowly when it was attributed to a slow speaker than when it was attributed to a fast speaker. Individual differences in one’s mimicry of the speaker moderated the influence of speaker-specific auditory images in reading. The influence was confirmed only for those who consciously mimicked the speaker. In contrast, situational cues manipulated to generate affiliation with and closeness to the speakers did not influence the participants’ reading times.

Early-life environments have been associated with various social behaviors, including trust, in late adolescence and adulthood. Given that the oxytocin receptor gene polymorphism (OXTR rs53576) moderates the impact of childhood experience on social behaviors, in the present study, we examined the main effect of childhood adversity through a self-report measure and its interactions with OXTR rs53576 on general trust among 203 Japanese and 200 European Canadian undergraduate students. After controlling for the effect of culture, the results indicated that childhood adversity had a negative association with general trust, and that OXTR rs53576 moderated the impact of childhood adversity on general trust. Specifically, the negative association between childhood adversity and general trust is only significant among homozygote A-allele carriers. These findings demonstrated that OXTR rs53576 moderated the relations between childhood experiences and social functioning in early adulthood.

We conducted two studies to examine the hypothesis that residential mobility would evoke anxiety and foster sensitivity to signs of disapproval, such as the disappearance of happiness. American and Japanese participants were asked to watch happy-to-neutral movies and sad-to-neutral movies and judge the point at which they thought that their initial expressions had disappeared. We found that, regardless of cultures, participants who had experienced frequent moving (Study 1) and those asked to imagine and describe a mobile lifestyle of frequent moving (Study 2) judged the disappearance of happy faces faster than those who did not experience or imagine frequent moving. Our results were also in line with the previous finding in which Japanese were more vigilant than Americans in regards to the disappearance of happy faces. Moreover, we found that imagining a mobile lifestyle made participants feel more concerned than when imagining a stable lifestyle. The implications for the social skills needed for people in the globalising world are discussed.

Previous research has demonstrated that the presence of a mirror does not influence Japanese people’s self-evaluation and cheating behaviors, which reflects their tendency to habitually think of themselves based on their imagined perspectives of others. The present work extends the evidence by manipulating the presence of the participants’ own voices as well as that of a mirror (Study 1); it explores the effects of another participant’s voice (Study 2). Consistent with previous findings, the presence of a mirror does not influence Japanese participants’ self-esteem, moral values, and cheating behaviors. In contrast, an impact of their own voice was partially found. The exposure to their own voice decreased the participants’ moral value of fairness and discouraged the participants from cheating by drawing additional coins. Furthermore, no effect of other voices was found. Overall, we observed a limited effect of self-focusing stimuli in Japanese participants, although it should be noted that their own voices were relatively effective for capturing self-focused attention.

<p>Previous research has demonstrated that when people have to choose a product for which they do not have a preference and can observe their partners' choices in advance, they are more likely to imitate their partners' choices when choosing privately, whereas they are likely to choose differently when they are with their partners. The present study extends this evidence by testing Japanese participants and examining individual differences in the need for uniqueness. Despite the Japanese cultural norm of interdependence, which is positively associated with conformity, less than half of the participants imitated their partners' choices, whether they chose privately or publicly. Moreover, people with a high need for uniqueness tended to choose a different option when choosing in front of their partners. Implications for the consequences of social influence are discussed.</p>

© 2018, The Author(s) 2018. People have to make different decisions every day, in which culture affects their strategies. This research examined the role of analytic versus holistic thinking style on resource allocation across cultures. We expected that, analytic thinking style, which refers to a linear view about the world where objects’ properties remain stable and separate, would make people concentrate their resource allocation corresponding to the current demand, whereas holistic thinking style, which refers to a nonlinear view that people perceive change to be a constant phenomenon and the universe to be full of interconnected elements, would encourage people to spread out their resource allocation. In Study 1, Hong Kong Chinese, a representative group of holistic cultures, and European Canadians, a representative group of analytic cultures, completed a resource allocation task (i.e., fort game). The results showed that the allocation pattern of European Canadians was more concentrated than that of Hong Kong Chinese and holistic thoughts predicted a less concentrated allocation pattern. To test causality, thinking styles were manipulated in Study 2, in which mainland Chinese were primed with either holistic thinking style or analytic thinking style. The results showed that the allocation pattern was more concentrated in the analytic condition than that in the holistic condition, which was explained by greater perceived predictability in the analytic condition. Implications of these findings on cross-cultural decision-making research and applied research were discussed.

© 2017 Elsevier Ltd. The present study investigated the association between a polymorphism of the serotonin 2A receptor (5-HT 2A R) gene and the form of impulsive choice known as delay discounting. Using a hypothetical situation, we asked Japanese participants to choose between receiving (or paying) a different amount of money immediately or with a specified delay (one week, two weeks, one month, six months, one year, five years, or 25years), and estimated the parameters of intertemporal choice models (exponential, hyperbolic, hyperbolic with exponent, and quasi-hyperbolic). Regardless of the genotypes, the hyperbolic with exponent model, which always indicated minimum AICc (Akaike Information Criterion with small sample correction), fitted better the observed data than the other models. Future gains were discounted more steeply than future losses. Moreover, as expected, individuals with the AA genotype of the 5-HT 2A R A-1438G polymorphism discounted the future more steeply than did individuals with the GG genotype, although this effect was limited to only gains. The findings implied individual differences based on the A-1438G polymorphism in the modulation of serotonin in the reward valuation underlying delay discounting.
