Abstract

Lookism encompasses discrimination based on a person's physical appearance. In a society where lookism is prevalent, the question arises concerning the impact of the fear of lookism on one's well‐being. To address this issue, we assessed the fear of anticipated appearance discrimination by constructing a new Fear of Lookism Scale (FLS). By testing 400 Japanese participants, we developed a three‐factor seven‐item scale and confirmed its convergent validity by establishing significantly positive correlations among its subscales (exclusion/devaluation, romantic rejection and insult) and related measures (physical appearance perfectionism and social appearance anxiety) in Study 1. In Study 2a, we gathered data from 312 Japanese participants to assess the scale's test–retest reliability. In Study 2b, combining data from 401 American participants with data from Study 2a, we verified FLS measurement invariance in the United States and Japan. Japanese participants scored higher on the FLS than Americans, particularly for exclusion/devaluation and insult. Across cultures, romantic rejection and insult were positively associated with physical appearance perfectionism, which, in turn, decreased subjective happiness through impacting self‐esteem (or increased loneliness) and increased subjective happiness through impacting self‐esteem (or decreased loneliness) respectively.

Although individuals of Latin American heritage ( Latin Americans in short) are considered interdependent, they also value traits like uniqueness and positivity, like individuals of European American cultural heritage, who are considered independent. It remains unclear whether this inclination toward positivity extends to a bias in self-perception known as self-enhancement. Moreover, if Latin Americans are indeed self-enhancing, it is uncertain how these tendencies align with their interdependent cultural orientation. In this article, we report three studies ( N = 1,246) with three operationalizations of self-enhancement. We found that Mexicans, Colombians, and Ecuadorians show self-enhancement that is mostly similar in magnitude to European Americans. Notably, Study 3 found that self-enhancement is related to interdependence in Latin America: Unlike European Americans, Latin Americans in Ecuador exhibited stronger self-enhancement when interdependence is primed rather than independence. Our findings suggest that among Latin American individuals, self-enhancement not only exists but also reinforces interdependence.

Abstract

We examined the relationship between socioeconomic status (SES) and endorsement of honour. We studied the SES‐honour link in 5 studies (N = 13,635) with participants recruited in different world regions (the Mediterranean and MENA, East Asian, South‐East Asian, and Anglo‐Western regions) using measures that tap into various different facets of honour. Findings from these studies revealed that individuals who subjectively perceived themselves as belonging to a higher (vs. lower) SES endorsed various facets of honour more strongly (i.e. defence of family honour values and concerns, self‐promotion and retaliation values, masculine honour beliefs, emphasis on personal and family social image, the so‐called street code). We discuss implications of these findings for the cultural dynamics linked to SES.

Mediterranean societies are often labeled as “honor cultures,” in contrast with presumed “dignity” and “face” cultures of Anglo-Western and East Asian societies. We measured these cultural logics in two large-scale surveys (Studies 1 & 3: N = 2,942 students from 11 societies; Study 2: N = 5,471 adults from 14 societies). Middle Eastern and North African groups perceived honor values as the most normative in their societies, followed by Southeast European, and then Latin-European groups (who were comparable to Anglo-Western and East-Asian groups). East-Asian and Anglo-Western groups, respectively, perceived face and dignity values as most normative. Culture-level variation in perceived normative honor values, but not personal values, accounted for previously reported differences between Mediterranean and non-Mediterranean samples in several (but not all) measures of social cognitive tendencies. We conclude that a cultural logic of honor plays a role in Mediterranean societies, but labeling these societies as “honor cultures” is oversimplistic.

Abstract

Working in a field that underrepresents populations outside Western societies, social psychologists in the Asia‐Pacific region encounter challenges in conducting research and imparting knowledge about social behaviour that resonates with local contexts. This paper argues that teaching can be a pathway for social psychology to rectify this representation problem. In this study, we report the results of our survey designed to contribute to an initial understanding of how and what social psychology is currently taught. Collectively, our survey respondents teach social psychology to over 12,000 students each year across 11 societies in the region. Results indicate that social psychology is seen as a crucial part of psychology education. About 80% of the respondents agreed that students should be taught that what is known in the international literature may not apply to a local context. At the same time, about 70% of the content taught was estimated to come from Western countries. Our findings highlight an opportunity for social psychology to evolve through teaching that embraces a more inclusive approach to meet societal demands for sound psychological knowledge.

Childhood adversity and health: The mediating roles of emotional expression and general trust Reviewed Open Access

Hiroki Hirano, Keiko Ishii

Frontiers in Psychology Vol. 15 page： 1493421 2024.11

Authorship：Last author Language：English Publishing type：Research paper (scientific journal) Publisher：Frontiers Media SA

Introduction

This study examined whether adverse childhood experiences, positive emotional expressivity in personal (i.e., expressing positive emotions when good things happened to oneself) and social settings (i.e., expressing positive emotions when good things happened to others such as friends or family), and general trust predict levels of happiness and loneliness among American and Japanese participants. We also explored whether these two types of emotional expression and general trust mediate the relationship between adverse childhood experiences and happiness/loneliness.

Methods

American and Japanese participants who agreed to participate in the current study first completed the Subjective Happiness Scale. Next, they answered the Emotion Expression Questionnaire, the 5-item General Trust Scale, and the revised UCLA Loneliness Scale. They then responded to the Risky Family Questionnaire. Finally, they answered demographic questions (e.g., age, gender). We hypothesized that regardless of culture, adverse childhood experiences would be negatively (positively) associated with happiness (loneliness), while positive emotional expression in personal and social settings and general trust would be positively (negatively) related to happiness (loneliness). We also predicted that positive emotional expression in both personal and social settings, as well as general trust, would mediate the relationships between adverse childhood experiences and happiness/loneliness.

Results

As expected, adverse childhood experiences were negatively (positively) associated with happiness (loneliness), while positive emotional expression in personal and social settings and general trust were positively (negatively) related to happiness (loneliness). Besides, positive emotional expression in a personal situation mediated the relationships between adverse childhood experiences and happiness/loneliness, such that greater early life adversity was negatively linked to positive emotional expressivity in a personal setting, which, in turn, predicted lower happiness and higher loneliness.

Discussion

The present study advances the understanding of psychological mechanisms linking adverse childhood experiences to happiness and loneliness by highlighting the significant role of positive emotional expression in a personal situation. This result underscores the importance of developing therapeutic practices and public health strategies that foster authentic emotional expression in response to personal achievement or fortune, regardless of cultural background.

Abstract

In the present work, we addressed the relationship between parental leave policies and social norms. Using a pre‐registered, cross‐national approach, we examined the relationship between parental leave policies and the perception of social norms for the gender division of childcare. In this study, 19,259 students (11,924 women) from 48 countries indicated the degree to which they believe childcare is (descriptive norm) and should be (prescriptive norm) equally divided among mothers and fathers. Policies were primarily operationalized as the existence of parental leave options in the respective country. The descriptive and prescriptive norms of equal division of childcare were stronger when parental leave was available in a country – also when controlling for potential confounding variables. Moreover, analyses of time since policy change suggested that policy change may initially affect prescriptive norms and then descriptive norms at a later point. However, due to the cross‐sectional nature of the data, drawing causal inferences is difficult.

ABSTRACT

Objective

We investigated the relationship between personal relative deprivation (PRD)—resentment from the belief that one is worse off than people who are similar to oneself—and locus of control.

Background

Research has yet to comprehensively investigate whether PRD is associated with a tendency to favor external (vs. internal) explanations for self‐ and other‐relevant outcomes.

Method

Eight studies (Ntotal = 6729) employed cross‐sectional, experimental, and (micro)longitudinal designs and used established trait and state measures of PRD and loci of control.

Results

Participants higher in PRD adopted more external (vs. internal) explanations for others' outcomes while controlling for socio‐demographics (e.g., socioeconomic status; Studies 1–4). This relationship was mediated by a lowered sense of personal control (Study 1) and evident in a cross‐national sample of participants in Asia (Study 2). PRD is more robustly associated with external than internal explanations for self and other‐relevant outcomes (Studies 5–8), and within‐person changes in PRD are positively associated with within‐person changes in external explanations (month‐to‐month and day‐to‐day; Studies 7–8).

Conclusions

PRD is positively associated with external locus of control independent of socioeconomic status, within and between people, and across cultures. This research highlights the implications of PRD for people's construal of the causal forces that govern their lives.

Abstract

Previous studies have documented cultural gaps in levels of well‐being, particularly within the contexts of individualistic and collectivistic nations. However, the underlying mechanisms responsible for the disparities remain incompletely understood. Therefore, the primary objective of this study was to explore how cross‐cultural differences in the use of emotion regulation (cognitive reappraisal and expressive suppression) and coping (problem‐focused and avoidant coping) predict health outcomes, specifically happiness and loneliness. As expected, the results of structural equation modelling demonstrated that American participants were more likely to use reappraisal and problem‐focused coping, both of which were positively associated with happiness but negatively linked to loneliness. In contrast, Japanese participants tended to lean toward suppression and avoidant coping, resulting in lower happiness and greater loneliness. Overall, the present findings affirm the substantial influence of cultural norms and values on regulatory strategies individuals employ in response to daily stressors, which are inextricably tied to human functioning.

Scholars have explained political orientation and morality as a consequence of epistemic needs and empathic motivation. In this study, we replicate previous research on the influence of psychological states on moral foundations, system justification, and political orientation among Japanese participants. Consistent with previous findings, empathy is positively associated with care and fairness (called individualizing foundations) whereas epistemic needs to manage certainty (e.g., need for closure) are positively associated with ingroup loyalty, respect for authority, and purity (called binding foundations). Empathy and the need for closure indirectly affect political orientation and system justification through their influence on moral foundations. Contrary to previous findings, we find empathy to be positively associated with binding foundations whereas the need for closure is positively associated with individualizing foundations. We discuss the implications of these findings to show that moral foundations are a result of motivated social cognition.

In six studies, we examined the accuracy and underpinnings of the damaging stereotype that feminists harbor negative attitudes toward men. In Study 1 ( n = 1,664), feminist and nonfeminist women displayed similarly positive attitudes toward men. Study 2 ( n = 3,892) replicated these results in non-WEIRD countries and among male participants. Study 3 ( n = 198) extended them to implicit attitudes. Investigating the mechanisms underlying feminists’ actual and perceived attitudes, Studies 4 ( n = 2,092) and 5 (nationally representative UK sample, n = 1,953) showed that feminists (vs. nonfeminists) perceived men as more threatening, but also more similar, to women. Participants also underestimated feminists’ warmth toward men, an error associated with hostile sexism and a misperception that feminists see men and women as dissimilar. Random-effects meta-analyses of all data (Study 6, n = 9,799) showed that feminists’ attitudes toward men were positive in absolute terms and did not differ significantly from nonfeminists'. An important comparative benchmark was established in Study 6, which showed that feminist women's attitudes toward men were no more negative than men's attitudes toward men. We term the focal stereotype the misandry myth in light of the evidence that it is false and widespread, and discuss its implications for the movement.

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.

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.

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.

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.

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 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.

© 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.
