Despite global commitments and efforts, a gender-based division of paid and unpaid work persists. To identify how psychological factors, national policies, and the broader sociocultural context contribute to this inequality, we assessed parental leave intentions in young adults (18-30 years old) planning to have children (N = 13,942; 8,880 identifi...
Chapter
Viewing humans as cultural agents, we argue that language provides a framework to perceive and experience emotions in a culturally prescribed manner, and thus is part and parcel of the cultural self. We first define our perspective on culture and the self and review comparative and contrastive cultural studies on emotional processes, specifically,...
Article
Full-text available
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 polymo...

Full-text available
To obtain further evidence to support spontaneous attention to vocal tones in Japanese, in this study, we developed a new set of stimuli, including positive and negative emotions, and investigated responses to facial and vocal displays of emotion by using behavioral and event-related potential (ERP) measurements. Japanese participants either judged...
Article
Full-text available
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 laborator...
Article
Full-text available
Previous work has reported a relation between pathogen-avoidance motivations and prejudice toward various social groups, including gay men and lesbian women. It is currently unknown whether this association is present across cultures, or specific to North America. Analyses of survey data from adult heterosexuals ( N = 11,200) from 31 countries show...
Article
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,...
Article
Full-text available
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...
Article
Full-text available
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 mod...
Article
Full-text available
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...
Article
Full-text available
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 i...
Article
Full-text available
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 polymorphis...
Article
Full-text available
Drawing on recent evidence suggesting that individuals having the G allele of the oxytocin receptor (OXTR) polymorphism are especially susceptible to socio-cultural environmental influences, including cultural norms, the present study investigated the interplay of culture and two OXTR polymorphisms (rs53576 and rs2254298) in the domain of emotional...
Article
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 reflect...
Chapter
Over the last decades, cultural psychologists have explored the relationship between culture and the mind and have reported that psychological processes, including daily emotional experiences, vary across cultures. In this chapter, we describe the theoretical framework of emotions from a cross-cultural perspective and review a selection of related...
Article
Full-text available
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 a...
Preprint
Theories in cultural psychology assume that emotions disrupt social harmony, and thus, emotion moderation is a hallmark of interdependence. However, this assumption is based exclusively on research on East Asians. Here, we tested the hypothesis that Latin Americans are as interdependent as East Asians and more so than European Americans. However, L...
Article
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-re...
Article
Full-text available
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 voic...
Article
Socioeconomic status (SES) is a multidimensional construct based on access to material resources and one's own rank relative to others in a social hierarchy. It fundamentally shapes individuals' psychological and behavioral tendencies. In many ways, socioeconomic variation parallels East-West cultural dynamics. Like East Asian cultures, lower SES f...
Article
Full-text available
What kind of life do people want? In psychology, a good life has typically been conceptualized in terms of either hedonic or eudaimonic well-being. We propose that psychological richness is another neglected aspect of what people consider a good life. In study 1 (9-nation cross-cultural study), we asked participants whether they ideally wanted a ha...
Article
Full-text available
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 e...
Article
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...
Article
Full-text available
Extending the literature on culture and the personal or interpersonal construction of choices, this research investigates consequences of an ingroup member's vicarious decision for the entire group and the mechanism behind cultural variation. In Study 1, Japanese people showed, compared to Germans, greater acceptance of vicarious choice and evaluat...
Article
Full-text available
Previous studies have shown that a cytosine (C) to thymine (T) single nucleotide polymorphism (SNP) of the human cannabinoid receptor 1 (CNR1) gene is associated with positive emotional processing. C allele carriers are more sensitive to positive emotional stimuli including happiness. The effects of several gene polymorphisms related to sensitivity...

Article
Full-text available
Previous research has indicated that, reflecting East Asians’ holistic attentional style, they are likely to emphasize more somatic symptoms and perceive their internal visceral states less accurately as compared with Westerners. Based on these findings, comparing representative samples of Americans and Japanese participants, this research examined...
Article
Full-text available
One’s generosity to others declines as a function of social distance, which is known as social discounting. We examined cultural similarities and differences in social discounting and the mediating roles of the two aspects of interdependence (self-expression and distinctiveness of the self) as well as the two aspects of independence (harmony-seekin...
Conference Paper
Full-text available
This research examined whether socioeconomic status (SES) predicts reactions to situations in which a group member decides for the entire group, thereby depriving other group members of personal choice. We found, as predicted, that Americans with higher subjective SES accepted choice deprivation less and demanded personal choice more than subjectiv...
Article
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...
Article
Full-text available
Happiness is regarded as one of the most fundamental human goals. Given recent reports that positive feelings are contagious (e.g., the presence of a happy person enhances others’ happiness) because of the human ability to empathize (i.e., sharing emotions), empathic ability may be a key factor in increasing one’s own subjective level of happiness....
Article
Previous research suggests that the benefits of different types of social support depend on cultural background. However, cultural variations in the underlying motivations for seeking social support and the emotional implications of receiving support have not yet been clearly explored. We hypothesized and found that European Americans emphasized th...
Article
Full-text available
East Asians tend towards holistic styles of thinking whereas Westerners generally think more analytically. Recent work has shown that Western participants perceive emotional expressions in a somewhat holistic manner, however. Specifically, Westerners interpret emotional facial expressions differently when presented with a body displaying a congruen...
Article
Full-text available
Previous studies showed that East Asians are more sensitive than North Americans to contextual information, and that the cultural differences in context sensitivity emerge in preschool children. Yet, little is known about whether this generalizes to children’s emotional judgments. The present study tested Canadian and Japanese preschool children an...
Article
Full-text available
Recent findings have re-examined the linguistic influence on cognition and perception, while identifying evidence that supports the Whorfian hypothesis. We examine how English and Japanese speakers perceive similarity of pairs of objects, by using two sets of stimuli: one in which two distinct linguistic categories apply to respective object images...
Article
Previous research indicates that people implicitly prefer self-chosen objects to other-chosen objects, even when both kinds of objects are in their possession. Extending this finding, we investigated how the number of choice options and independent vs. interdependent social orientations affect this choice effect in Japanese students. Using the impl...
Article
Full-text available
Although human saliva contains the monoamine serotonin, which plays a key role in the modulation of emotional states, the association between salivary serotonin and empathic ability remains unclear. In order to elucidate the associations between salivary serotonin levels, trait empathy, and the sharing effect of emotions (i.e., sharing emotional ex...
Article
Does a major natural disaster change human values and job preferences? The present studies examined whether the experience of a natural disaster experience shifts people's values and job preferences toward pro-social directions. In Study 1 (cross-temporal analysis), we analysed job application data in nine cities in Japan over 12 years and found th...
Article
The present study investigated the association between a polymorphism of the serotonin 2A receptor (5-HT2AR) 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 w...
Article
People generally tend to discount future outcomes in favor of smaller but immediate gains (i.e., delay discounting). This study examines the hypothesis that culture and social status moderate this tendency, as well as the alternative hypothesis that social status and culture influence delay discounting independently of each other. American and Japa...
Chapter
Full-text available
In this chapter, we describe the theoretical framework of emotions from a cross-cultural perspective and selectively review related findings arguing for the cultural dependence of emotions. Focusing on East Asians, we specifically present research concerning the strong belief that emotions do not merely represent internal states, but are constitute...
Article
Full-text available
Objectives: People generally tend to discount future outcomes in favor of smaller but immediate gains (i.e., delay discounting). The present research examined cultural similarities and differences in delay discounting of gain and loss between Chinese and Japanese, based on a q-exponential model of intertemporal choice. Method: Using a hypothetic...
Article
Full-text available
People who are more avoidant of pathogens are more politically conservative, as are nations with greater parasite stress. In the current research, we test two prominent hypotheses that have been proposed as explanations for these relationships. The first, which is an intragroup account, holds that these relationships between pathogens and politics...
Article
Research on sustainability behaviors has been based on the assumption that increasing personal concerns about the environment will increase proenvironmental action. We tested whether this assumption is more applicable to individualistic cultures than to collectivistic cultures. In Study 1, we compared 47 countries (N = 57,268) and found that they v...
Article
Full-text available
Utilizing three student (Study 1) and non-student samples (Study 2), we examined cultural differences in workplace choice for North Americans, Germans, and Japanese. We focused on the desire for control as a potential mediator (i.e., the underlying mechanism) to explain cultural differences in this important life decision. Given culturally divergen...
Article
Previous findings in culture and attention reported mixed results. While some studies demonstrated systematic cultural variations in patterns of eye movement, other studies reported that the magnitude of the effects is minor. To further scrutinize when cultural variations in attention are attenuated or enhanced, we conducted a new series of visual...
Article
Full-text available
Previous research has shown that culture and genes can interact to influence social behaviors. Variation of the oxytocin receptor gene (OXTR) rs53576 polymorphism has been linked to differential susceptibility to cultural influences with genetically susceptible individuals showing more culturally typical behaviors. The present research focuses on a...
Article
Full-text available
Under the influences of globalization and a long recession, there is an increasing population of marginalized Japanese youth referred to as NEET (Not in Employment, Education, or Training). Past studies have suggested that the social withdrawal of these individuals is a manifestation of a denial of the dominant cultural value of interdependence and...
Article
Full-text available
People generally discount future outcomes, and accordingly accept immediate but smaller gain. This research examined whether this tendency (i.e., delay discounting) is associated with socioeconomic status (SES) and smoking status, and hypothesized that the influence of SES on delay discounting would be moderated by smoking status. Using an Internet...
Article
We investigated psychological adaptation to the Great Hanshin-Awaji Earthquake of 1995, using surveys conducted in 2001, 2003, 2005, and 2011. Respondents whose houses were damaged reported lower life satisfaction, more negative affect, and more health problems than those who did not suffer any damage in all surveys, including in 2011, or 16 years...
Article
Full-text available
Hokkaido-a northern island of Japan that was settled by ethnic Japanese during the late nineteenth century and the early twentieth century-may remain to be a hybrid of interdependent culture of the mainland Japan and independent culture associated with frontier settlement. We thus anticipated that contemporary Hokkaido residents would exhibit eithe...
Article
Full-text available
Research on cultural products suggest that there are substantial cultural variations between East Asian and European landscape masterpieces and contemporary members’ landscape artwork (Masuda et al., 2008c ), and that these cultural differences in drawing styles emerge around the age of 8 (Senzaki et al., 2014b ). However, culture is not static. To...
Article
Voluntary settlement is linked to the ethos of independence. However, it is unclear whether initial cultural contexts in frontier areas influence this ethos. The present study focused on Hokkaido, a Japanese island with a history of voluntary settlement, and predicted that while the predominant mainland-Japanese ethos of interdependence is prevalen...
Article
Full-text available
The present research investigated an association between the serotonin transporter polymorphism (5-HTTLPR) and sensitivity to the disappearance of facial expressions cross-culturally and found, for the first time, that cultural norms and practices modulate the association. Participants watched both happy-to-neutral and sad-to-neutral movies and jud...
Article
Previous findings in cultural psychology indicated that East Asians are more likely than North Americans to be attentive to contextual information (e.g., Nisbett & Masuda, ). However, to what extent and in which conditions culture influences patterns of attention has not been fully examined. As a result, universal patterns of attention may be obscu...
Article
Full-text available
We examined how cultural values of harmony and uniqueness are represented and maintained through physical media (i.e., colorings of geometric patterns) and how individuals play an active role in selecting and maintaining such cultural values. We found that colorings produced by European American adults and children were judged as more unique, where...
