Using data from 15 countries, this article investigates whether descriptive and prescriptive gender norms concerning housework and child care (domestic work) changed after the onset of the COVID-19 pandemic. Results of a total of 8,343 participants (M = 19.95, SD = 1.68) from two comparable student samples suggest that descriptive norms about unpaid domestic work have been affected by the pandemic, with individuals seeing mothers' relative to fathers' share of housework and child care as even larger. Moderation analyses revealed that the effect of the pandemic on descriptive norms about child care decreased with countries' increasing levels of gender equality; countries with stronger gender inequality showed a larger difference between pre- and post-pandemic. This study documents a shift in descriptive norms and discusses implications for gender equality-emphasizing the importance of addressing the additional challenges that mothers face during health-related crises.

OBJECTIVES: Previous studies have indicated that good human relationships contribute significantly to subjective well-being. We recently focused on two important ways of developing good interpersonal relationships: positive empathy, which focuses on the happiness of other people, and trait forgivingness, a tendency to forgive others. We novelly conducted an exploratory genome-wide association study (GWAS) to identify candidate gene polymorphisms associated with positive empathy and trait forgivingness among the Japanese. MATERIAL AND METHODS: We for the first time identified several genetic polymorphisms associated with positive empathy and trait forgivingness through the GWAS based on a small sample population and relatively low threshold. We subsequently validated three genetic polymorphisms from these candidate genes using a real-time polymerase chain reaction system. RESULTS: The results demonstrated that polymorphism in the vomeronasal type-1 receptor 1 (VN1R1) (rs61744949), a putative human pheromone receptor, is associated with positive empathy. In addition, genetic polymorphisms in the 5-hydroxytryptamine (serotonin) receptor 7 (HTR7: rs77843021) and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, epsilon (YWHAE: rs9908013), which are associated with dopamine and serotonin biosynthesis, are associated with trait forgivingness. CONCLUSION: This study novelly illustrated the influence of the genetic polymorphism in VN1R1 on positive empathy and that of genetic polymorphisms in HTR7 and YWHAE on trait forgivingness. It identified a relationship between previously unreported genetic polymorphisms and the necessary abilities for developing good human relationships. This will significantly impact future research on positive psychology and social psychology.

Evidence suggests that Latin Americans display elevated levels of emotional expressivity and positivity. Here, we tested whether Latin Americans possess a unique form of interdependence called expressive interdependence, characterized by the open expression of positive emotions related to social engagement (e.g., feelings of closeness to others). In Study 1, we compared Latin Americans from Chile and Mexico with European Americans in the United States, a group known to be highly independent. Latin Americans expressed positive socially engaging emotions, particularly in response to negative events affecting others, whereas European Americans favored positive socially disengaging emotions, such as pride, especially in response to personally favorable circumstances. Study 2 replicated these findings with another group of Latin Americans from Colombia and European Americans in the United States. Study 2 also included Japanese in Japan, who expressed positive emotions less than Latin and European Americans. However, Japanese displayed a higher tendency to express negative socially engaging emotions, such as guilt and shame, compared to both groups. Our data demonstrate that emotional expression patterns align with overarching ethos of interdependence in Latin America and Japan and independence among European Americans. However, Latin Americans and Japanese exhibited different styles of interdependence. Latin Americans were expressive of positive socially engaging emotions, whereas Japanese were less expressive overall. Moreover, when Japanese expressed emotions, they emphasized negative socially engaging emotions. Implications for theories of culture and emotion are discussed.

This research explores how culture influences the motivations underlying explicit (emotional and instrumental) and implicit (companionship and attentiveness) support provision. Two studies (N = 1,106) compared the responses of European Americans and Japanese individuals to a close other’s stressful event. The results showed that European Americans were more likely than Japanese to provide explicit support and more motivated to increase the close other’s self-esteem and feeling of closeness. Conversely, Japanese individuals were more likely to provide attentiveness support, motivated by concern for an entire group and a friend. These findings support the motivation as a mediator hypothesis. On the other hand, the culture as a moderator hypothesis applied to the association between concern for an entire group motivation and implicit support provision. Specifically, concern for an entire group motivation predicted companionship support provision only in Japanese, while it predicted attentiveness support provision mainly in European Americans.

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.

Introduction

Social support-seeking is considered to be an effective way for international students to cope with their acculturative stress and contribute to cross-cultural adaptation. In addition to support from people in the host country (close support), the ease of online communication now allows international students to receive additional support from people back in their home country (distant support). However, little research has investigated whether distant support works as effectively as close support. In two studies, we examined the differential effect of distant and close support-seeking on the psychological adaptation of Chinese international students in the host country and how acculturation orientations relate to the use of these two types of support.

Methods

Chinese international students in Japan (Study 1; N = 172) and the United States (Study 2; N = 118) completed an online survey that assessed participants’ host/home culture orientation, distant emotional/instrumental support-seeking, close emotional/instrumental support-seeking, and psychological adaptation.

Results

Results showed that distant emotional support-seeking negatively predicted psychological adaptation in the host country. Nevertheless, distant emotional support-seeking alleviated feelings of loneliness in Chinese international students as close emotional support-seeking did (Study 2). Also, the results showed that international students with higher home-culture orientation sought more distant support, whereas those with higher host-culture orientation sought more close support. Further, Chinese-culture orientation increased distant emotional support-seeking, decreasing psychological adaptation as well as loneliness.

Discussion

These findings highlight the importance of considering the source and types of support when discussing the implications of social support for the cross-cultural adaptation of international students.

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.

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 supportthe effects, we assigned 47 Japanese participants randomly to either anacting 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 ofmind and the other facets of empathy. Implications for future work in applied settings 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.

<p>A fundamental question is how cultural phenomena are created (i.e., how cultures are formed and maintained, and why different cultures have emerged). One approach to this question is to focus on the possibility that genes and sociocultural environments have coevolved and interacted. This review highlights empirical findings on the coevolution of genes and culture and the genetic basis of sociocultural differences including Western and Eastern cultural differences. Moreover, this review refers to the problem of false-positive associations between gene polymorphism and behavioral traits in the studies on gene and culture coevolution and interaction. Future directions and research strategies in studies on gene and culture coevolution and interaction are discussed.</p>

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 (<italic>DRD2</italic>: rs1800497). Results showed gene–gene interactions between haplogroups D-M55 and <italic>DRD2</italic> in BMI. Based on these findings, it is demonstrated that Y-DNA haplogroup D is associated with human personality.

<p>The dopamine D4 receptor gene (DRD4) is associated with novelty-seeking and risk-taking behaviors that have had an adaptive value in the history of human migration. It also plays a role in moderating the extent to which people adhere to cultural norms and practices. The aim of this study was to replicate previous findings about how DRD4 polymorphism interacts with cultural differences in social orientation, which revealed Westerners’ emphasis on independence and East Asians’ emphasis on interdependence. Testing Japanese and European Canadian undergraduates (n = 784), we succeeded in replicating these previous findings: the Canadian students were more independent, whereas the Japanese students were more interdependent. However, none of the interaction effects between culture and DRD4 were significant. Implications for candidate gene research investigating gene–environment and gene–culture interactions are discussed.</p>

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. 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.

<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.
