The impact of culture on emotion suppression: Insights from an electrophysiological study of emotion regulation in Japan.

Prior theory and evidence suggest that native East Asians tend to down-regulate their emotional arousal to negatively valenced experiences through expressive suppression, an emotion regulation technique focused on suppressing one's emotional experience. One proposed explanation for this choice of regulation strategy and its efficacy is rooted in their commitment to the cultural value of interdependence with others. However, prior work has not yet thoroughly supported this hypothesis using in vivo neural correlates of emotion regulation. Here, we utilized an established electroencephalogram (EEG) correlate of emotional arousal, the late positive potential (LPP), to examine whether down-regulation of the LPP in native East Asians might be particularly pronounced for those relatively high in interdependent self-construal. In this study, native Japanese participants attempted to suppress their emotional reaction to unpleasant images during EEG recording. In support of the hypothesis that emotion suppression among native East Asians is influenced by the cultural value of interdependence, there was a significant effect of interdependent self-construal on the LPP. Specifically, those relatively high in interdependent (versus independent) self-construal exhibited a smaller LPP in response to unpleasant pictures when instructed to suppress their emotions versus a passive viewing condition. However, this effect was negligible for those relatively low in interdependent self-construal, suggesting that cultural values impact the in vivo efficacy of different emotion regulation techniques. These results demonstrate the importance of identifying correspondence between self-report measures and in vivo correlates of emotion regulation in cross-cultural research.

Interdependent culture and older adults' well-being: Health and psychological happiness in Japanese communities.

This review article examined perspectives on the well-being and health of older adults in Japan, a nation renowned for its longevity. We emphasized the impact of social capital and social relationships in local communities, considering both individual and societal factors. The prevailing values in Japanese culture tend to foster a sustained and stable form of interdependent happiness among older adults, suggesting that communal support systems play an important role. This article highlights the value of multi-level datasets, such as the Japan Gerontological Evaluation Study (JAGES) dataset, for understanding the influence of social participation on the health and well-being of older adults. A growing body of evidence underscores the central role of social relationships in the health and well-being of older adults.

Emotion regulation strategies and psychological health across cultures.

Emotion regulation is important for psychological health and can be achieved by implementing various strategies. How one regulates emotions is critical for maximizing psychological health. Few studies, however, tested the psychological correlates of different emotion regulation strategies across multiple cultures. In a preregistered cross-cultural study (N = 3,960, 19 countries), conducted during the COVID-19 pandemic, we assessed associations between the use of seven emotion regulation strategies (situation selection, distraction, rumination, cognitive reappraisal, acceptance, expressive suppression, and emotional support seeking) and four indices of psychological health (life satisfaction, depressive symptoms, perceived stress, and loneliness). Model comparisons based on Bayesian information criteria provided support for cultural differences in 36% of associations, with very strong support for differences in 18% of associations. Strategies that were linked to worse psychological health in individualist countries (e.g., rumination, expressive suppression) were unrelated or linked to better psychological health in collectivist countries. Cultural differences in associations with psychological health were most prominent for expressive suppression and rumination and also found for distraction and acceptance. In addition, we found evidence for cultural similarities in 46% of associations between strategies and psychological health, but none of this evidence was very strong. Cultural similarities were most prominent in associations of psychological health with emotional support seeking. These findings highlight the importance of considering the cultural context to understand how individuals from diverse backgrounds manage unpleasant emotions.

Gender differences in perceived legitimacy and status perception in leadership role.

The present study examined the difference between women and men in perceiving leadership roles. Two experiments, one conducted online and the other in a lab, investigated the subjective experiences of Japanese men and women when they are assigned with different roles (e.g., leader vs. subordinate). Both studies revealed that women perceived their role as less legitimate when they were assigned leader role (vs. subordinate role). In contrast, men did not differ in their perceived legitimacy according to the assigned roles. This discrepancy in legitimacy perception in response to different roles between men and women accounted for a significant variance in women's lower sense of status when they were a leader (vs. subordinate), but not among men. Our study results illustrate the psychological barrier operating for women in organizations that are embedded in a cultural context in which women leaders are highly underrepresented.

Neither Eastern nor Western: Patterns of independence and interdependence in Mediterranean societies.

Social science research has highlighted "honor" as a central value driving social behavior in Mediterranean societies, which requires individuals to develop and protect a sense of their personal self-worth and their social reputation, through assertiveness, competitiveness, and retaliation in the face of threats. We predicted that members of Mediterranean societies may exhibit a distinctive combination of independent and interdependent social orientation, self-construal, and cognitive style, compared to more commonly studied East Asian and Anglo-Western cultural groups. We compared participants from eight Mediterranean societies (Spain, Italy, Greece, Turkey, Cyprus [Turkish Cypriot and Greek Cypriot communities], Lebanon, Egypt) to participants from East Asian (Korea, Japan) and Anglo-Western (the United Kingdom, the United States) societies, using six implicit social orientation indicators, an eight-dimensional self-construal scale, and four cognitive style indicators. Compared with both East Asian and Anglo-Western samples, samples from Mediterranean societies distinctively emphasized several forms of independence (relative intensity of disengaging [vs. engaging] emotions, happiness based on disengaging [vs. engaging] emotions, dispositional [vs. situational] attribution style, self-construal as different from others, self-directed, self-reliant, self-expressive, and consistent) and interdependence (closeness to in-group [vs. out-group] members, self-construal as connected and committed to close others). Our findings extend previous insights into patterns of cultural orientation beyond commonly examined East-West comparisons to an understudied world region.

Proximal and distal honor fit and subjective well-being in the Mediterranean region.

OBJECTIVE: People's psychological tendencies are attuned to their sociocultural context and culture-specific ways of being, feeling, and thinking are believed to assist individuals in successfully navigating their environment. Supporting this idea, a stronger "fit" with one's cultural environment has often been linked to positive psychological outcomes. The current research expands the cultural, conceptual, and methodological space of cultural fit research by exploring the link between well-being and honor, a central driver of social behavior in the Mediterranean region. METHOD: Drawing on a multi-national sample from eight countries circum-Mediterranean (N = 2257), we examined the relationship between cultural fit in honor and well-being at the distal level (fit with one's perceived society) using response surface analysis (RSA) and at the proximal level (fit with one's university gender group) using profile analysis. RESULTS: We found positive links between fit and well-being in both distal (for some, but not all, honor facets) and proximal fit analyses (across all honor facets). Furthermore, most fit effects in the RSA were complemented with positive level effects of the predictors, with higher average honor levels predicting higher well-being. CONCLUSIONS: Our findings highlight the interplay between individual and environmental factors in honor as well as the important role honor plays in well-being in the Mediterranean region.

Self-construal and behavioral motivation systems among patients with depression in Indonesia: A hospital-based study.

Objective: To validate Indonesian versions of two social/cultural psychological scales: the Self-Construal Scale (SCS) that measures independent and interdependent cultural values, and the Behavioral Inhibition (Avoidance) System and Behavioral Approach System (BIS/BAS) that measures motivation focus. We also explored the cultural background for the rising prevalence of depression in Indonesia. Design: Case (hospital)-control (population) study. Setting: Hasanuddin University Hospital (cases) and Makassar city region (controls), Indonesia. Participants: Participants (N = 369) were 165 patients with depression recruited from a university hospital, and 204 healthy controls without a history of mental disorders recruited from locations within a 30-minute walk from the hospital. Outcome measures: Depression was diagnosed by psychiatrists with reference to Indonesian mental disorder guidelines (Pedoman Penggolongan dan Diagnosa Gangguan Jiwa edisi 3). Participants' independent and interdependent cultural values, and neural motivational systems were measured with the SCS and BIS/BAS. Results: Exploratory and confirmatory factor analyses showed that our revised 12-item SCS and the 13-item, three-factor BIS/BAS had a good model fit for the Indonesian population. MANCOVA showed that the SCS Independent subscale and the BAS subscales were significantly associated with depression after adjustment for age, sex, religion, education, and occupation. Conclusion: These findings may guide provision of appropriate treatment for patients based on their social and cultural environment. In addition, this study contributes to understanding underlying reasons for the increasing prevalence of depression in Indonesia, where society is changing from traditional collectivism to global individualism.

Extracting multiple layers of social networks through a 7-month survey using a wearable device: a case study from a farming community in Japan.

As individuals are susceptible to social influences from those to whom they are connected, structures of social networks have been an important research subject in social sciences. However, quantifying these structures in real life has been comparatively more difficult. One reason is data collection methods-how to assess elusive social contacts (e.g., unintended brief contacts in a coffee room); however, recent studies have overcome this difficulty using wearable devices. Another reason relates to the multi-layered nature of social relations-individuals are often embedded in multiple networks that are overlapping and complicatedly interwoven. A novel method to disentangle such complexity is needed. Here, we propose a new method to detect multiple latent subnetworks behind interpersonal contacts. We collected data of proximities among residents in a Japanese farming community for 7 months using wearable devices which detect other devices nearby via Bluetooth communication. We performed non-negative matrix factorization (NMF) on the proximity log sequences and extracted five latent subnetworks. One of the subnetworks represented social relations regarding farming activities, and another subnetwork captured the patterns of social contacts taking place in a community hall, which played the role of a "hub" of diverse residents within the community. We also found that the eigenvector centrality score in the farming-related network was positively associated with self-reported pro-community attitude, while the centrality score regarding the community hall was associated with increased self-reported health.

Outside the "Cultural Binary": Understanding Why Latin American Collectivist Societies Foster Independent Selves.

Cultural psychologists often treat binary contrasts of West versus East, individualism versus collectivism, and independent versus interdependent self-construal as interchangeable, thus assuming that collectivist societies promote interdependent rather than independent models of selfhood. At odds with this assumption, existing data indicate that Latin American societies emphasize collectivist values at least as strongly as Confucian East Asian societies, but they emphasize most forms of independent self-construal at least as strongly as Western societies. We argue that these seemingly "anomalous" findings can be explained by societal differences in modes of subsistence (herding vs. rice farming), colonial histories (frontier settlement), cultural heterogeneity, religious heritage, and societal organization (relational mobility, loose norms, honor logic) and that they cohere with other indices of contemporary psychological culture. We conclude that the common view linking collectivist values with interdependent self-construal needs revision. Global cultures are diverse, and researchers should pay more attention to societies beyond "the West" and East Asia. Our contribution concurrently illustrates the value of learning from unexpected results and the crucial importance of exploratory research in psychological science.

Horror, fear, and moral disgust are differentially elicited by different types of harm.

Witnessing or experiencing extreme and incomprehensible harm elicits an intense emotional response that is often called "horror." Although traditional emotion taxonomies have categorized horror as a subtype of fear and/or disgust, recent empirical work has indicated that horror is a distinct emotion category (Cowen & Keltner, 2017). However, exactly how horror is different from fear and disgust has remained unclear. The current studies represent the first empirical attempt to clarify how horror is distinct from fear and moral disgust. Results indicated that these emotions are elicited by different aspects of harm: horror is a response to the severity or abnormality of harm, fear to the self-relevance of harm, and moral disgust to the harm's causal agent. In a survey of personal experiences of emotions (Study 1), participants reported having felt horror in response to the actual occurrence of extreme or abnormal harm, but felt fear and moral disgust in response to events involving no harm or only mild harm. Participants also reported greater cognitive disruption (e.g., disbelief, schema-incongruence) during horror than during fear or moral disgust. Experiments testing the effects of different aspects of harm on emotion ratings indicated that horror was differentially increased by harm that was abnormal (vs. common) and had already occurred (vs. potential threat), whereas fear was differentially increased by harm that had high (vs. low) self-relevance (Study 2). Further, extreme (vs. mild) harm differentially increased horror, but the presence (vs. absence) of a blameworthy agent differentially increased moral disgust (Study 3).

Different bumps in the road: The emotional dynamics of couple disagreements in Belgium and Japan.

In the present study, we propose that the emotional "bumps" that couples experience during relationship disagreements differ systematically among cultures. We predicted that self-assertive emotions such as anger or strength play a central role in Belgium, where they are instrumental for relational independence. In comparison, other-focused emotions such as shame or empathy for the partner should play a central role in Japan, where they support relational interdependence. Romantic couples from Belgium (n = 58) and Japan (n = 80) discussed relationship disagreements in the lab, which were video-recorded. After the interaction, participants separately rated their emotional experience during video-mediated recall. We identified the emotions that played a central role during the interactions in terms of attractors; these are the emotions around which couples stabilize and that likely play a central role in realizing different relationship ideals. In line with our predictions, attractors reflected states of the interpersonal emotional system that support independence in Belgium (e.g., angry or strong feelings) and interdependence (e.g., empathy) in Japan. Moreover, we found that-at least in Belgium-having more culturally typical interactions was associated with a stronger endorsement of culturally valued relationship ideals and, in turn, better relational functioning.

Who Can Buffer Marginalization Risk? Affect Experience, Affect Valuation, and Social Marginalization in Japan and Brazil.

Previous research has associated social marginalization with the rejection of mainstream cultural values. Since cultural values reflect affect valuation, the present research investigates the relationships between social marginalization and ideal/actual affect in two different non-WEIRD cultures, Brazil and Japan. As a social marginalization index, we used the NEET-Hikikomori Risk Scale (NHR). We predicted that cultural differences would emerge in the valuation of affective states. Affect valuation theory suggests that in East Asia, individuals are encouraged to pursue and value low arousal positive emotions (LAP: e.g., calmness, serenity) over high arousal positive emotions (HAP: e.g., excitement, elation, etc.) as they can harm social relationships in these societies. In contrast, Latin American cultures value HAP over LAP, because social relationships are promoted through vibrant positive emotional expression in these cultures. Hence, we hypothesized that individuals' ideal affect, actual affect, and the discrepancy between ideal and actual affect would be associated with higher risk of social marginalization. Participants from Japan (N = 54) and Brazil (N = 54) reported their ideal affect and actual affect and completed the NEET-Hikikomori Risk Scale (NHR). Regression analyses showed that actual HAP and the discrepancy between ideal and actual HAP were negatively associated with NHR in Brazil, but no association was found in the Japanese data. The other variables, including ideal affect, were only minorly or not significantly associated with NHR. Though the study has limitations regarding its small sample size, we can explore future perspectives and discuss the relationships between emotion and cultural marginalization. Socioecological factors that promote actual HAP in Brazilians may encourage other mainstream cultural ideals, which buffers against cultural marginalization.

Cultural differences in music features across Taiwanese, Japanese and American markets.

BACKGROUND: Preferences for music can be represented through music features. The widespread prevalence of music streaming has allowed for music feature information to be consolidated by service providers like Spotify. In this paper, we demonstrate that machine learning classification on cultural market membership (Taiwanese, Japanese, American) by music features reveals variations in popular music across these markets. METHODS: We present an exploratory analysis of 1.08 million songs centred on Taiwanese, Japanese and American markets. We use both multiclass classification models (Gradient Boosted Decision Trees (GBDT) and Multilayer Perceptron (MLP)), and binary classification models, and interpret their results using variable importance measures and Partial Dependence Plots. To ensure the reliability of our interpretations, we conducted a follow-up study comparing Top-50 playlists from Taiwan, Japan, and the US on identified variables of importance. RESULTS: The multiclass models achieved moderate classification accuracy (GBDT = 0.69, MLP = 0.66). Accuracy scores for binary classification models ranged between 0.71 to 0.81. Model interpretation revealed music features of greatest importance: Overall, popular music in Taiwan was characterised by high acousticness, American music was characterised by high speechiness, and Japanese music was characterised by high energy features. A follow-up study using Top-50 charts found similarly significant differences between cultures for these three features. CONCLUSION: We demonstrate that machine learning can reveal both the magnitude of differences in music preference across Taiwanese, Japanese, and American markets, and where these preferences are different. While this paper is limited to Spotify data, it underscores the potential contribution of machine learning in exploratory approaches to research on cultural differences.

Do you feel happy when other members look happy? Moderating effect of community-level social capital on interconnection of happiness.

One's happiness is expected to be affected by the happiness of surrounding others. This socio-psychological nature of happiness, however, has not been fully examined in the literature of social psychology. The current study examined if this "psychological interconnection of happiness" occurs when (i) individuals have strong personal social capital and/or (ii) individuals belong to a community where other members have strong social capital. We analysed a large social survey dataset sampled from 408 communities in Japan (N = 7295). The psychological interconnection of happiness was measured by calculating the correlation between individual happiness and perceived community happiness. The multilevel analyses revealed that the psychological interconnection of happiness was moderated by community-level social capital above and beyond individual-level social capital, while individual-level social capital did not have a significant moderation effect.

Cultural Differences in Emotion Suppression in Belgian and Japanese Couples: A Social Functional Model.

Emotion suppression has been found to have negative psychological and social consequences in Western cultural contexts. Yet, in some other cultural contexts, emotion suppression is less likely to have negative consequences; relatedly, emotion suppression is also more common in those East-Asian cultural contexts. In a dyadic conflict study, we aim to (a) conceptually replicate cultural differences found in previous research with respect to the prevalence and consequences of emotion suppression, and (b) extend previous research by testing whether cultural differences are larger for some than for other types of negative emotions. We postulate that cultural differences in suppression are less pronounced for socially engaging emotions (e.g., guilt) than socially disengaging emotions (e.g., anger), because the former foster the relationship, whereas the latter emphasize individual goals. Belgian (N = 58) and Japanese (N = 80) couples engaged in a 10-min conflict interaction followed by video-mediated recall, during which participants rated their emotions and emotion suppression every 30 s. As predicted, Japanese participants reported more suppression than their Belgian counterparts, but the cultural difference was more pronounced when participants experienced more socially disengaging emotions than when they experienced more socially engaging emotions. These results suggest that the type of emotion should be considered when describing cultural differences in emotion suppression. Finally, and consistent with previous research, emotion suppression was negatively associated with interaction outcomes (i.e., conflict resolution) in Belgian couples, but not in Japanese couples.

A Multifaceted Evaluation on the Penetration Resistance of Protective Clothing Fabrics against Viral Liquid Drops without Pressure.

Healthcare workers should wear appropriate personal protective clothing (PPC) on assuming the risk of exposure to various pathogens. Therefore, it is important to understand PPC performance against pathogen penetration. Currently, standard methods to evaluate and classify the penetration resistance of PPC fabrics with pressure using synthetic blood or phi-X174 phage have been established by the International Organization for Standardization (ISO). However, the penetration of viral liquid drops (VLDrop) on the PPC without pressure is also a major exposure route and more realistic, necessitating further studies. Here, we evaluated the penetration resistance against VLDrop without pressure using phi-X174 phage on woven and nonwoven fabrics of commercially available PPC classified by the ISO, and analyzed in detail the penetration behaviors of VLDrop by quantifying the phage amounts in leak-through and migration into test fabrics. Our results showed that some nonwoven test fabrics had nearly the same penetration resistance against VLDrop, even if the ISO resistance class differed. Furthermore, the results revealed that the amount of leakage through the fabrics was correlated with the migration amount into the fabric, which was related to fluid-repellency of fabrics, suggesting the effectiveness for penetration resistance. Our study may facilitate more appropriate selection for PPC against pathogen penetration.

How do socio-ecological factors shape culture? Understanding the process of micro-macro interactions.

Socio-ecological environments produce certain psychological functions. that are adaptive for survival in each environment. Past evidence suggests that interdependence-related psychological features are prevalent in East Asian cultures partly due to the history of 'rice-crop farming' (versus herding) in those areas. However, it is unclear how and why certain functional behaviors required by the socio-ecological environment are sublimated to become cultural values, which are then transmitted and shared among people. In this paper, we conceptually review the works examining various macro sharing processes for cultural values, and focus on the use of multilevel analysis in elucidating the effect of both macro and individual level factors. Uchida et al.'s study (2019) suggests that collective activities at the macro level (community-level), which is required by a certain socio-ecological environment, promote interdependence not only among farmers but also non-farmers. The multilevel processes of how psychological characteristics are construed by macro factors will be discussed.

Increased adhesion of methicillin-resistant Staphylococcus aureus to the surface of personal protective clothing damaged by friction during nursing action.

BACKGROUND: Health care workers wear protective clothing when caring for patients with infectious diseases. However, during the action of patient care, the generated contact pressure may damage the surface of the protective clothing. METHODS: Fabrics of protective clothing were damaged by a machine using a force similar to the contact pressure that occurs during nursing care. A total of 50 µL of blood containing methicillin-resistant Staphylococcus aureus (MRSA) (5 × 106 colony-forming units/mL) was dropped onto the pressed or rubbed fabrics. After removing the blood, the residual bacterial count on the surface of the clothing was measured. RESULTS: In the undamaged fabrics, the number of adherent MRSA was significantly higher on class 6 protective clothing than on the other tested clothing. The number of adherent MRSA significantly increased on the rubbed surgical gown and rubbed class 3 protective clothing than on the undamaged clothing. CONCLUSIONS: Because the damaged fabrics of protective clothing may cause bacterial carryover, health care workers should pay attention to preventing self-contamination when doffing the protective clothing.

The Self-Construal Scale: A Potential Tool for Predicting Subjective Well-Being of Individuals With Autism Spectrum Disorder.

Despite accumulating evidence that culture shapes the symptoms of autism spectrum disorder (ASD), no studies have yet applied the Self-Construal Scale to individuals with ASD. We compared the self-construals (measured using the Self-Construal Scale) of 31 high-functioning Japanese individuals with ASD with those of 60 typically developing (TD) individuals. We also examined how the self-construals of individuals with ASD related to their intelligence quotient, adverse childhood experiences, attention deficit hyperactivity disorder, ASD symptoms during adulthood and preschool years, and subjective well-being. Individuals with ASD were more likely to display independent self-construals than were TD individuals; unexpectedly, however, a substantial proportion of individuals with ASD (43.8%) displayed relatively interdependent self-construals. Among individuals with ASD, self-construals were significantly associated with ASD symptoms during preschool years, and with satisfaction of the need for autonomy and frustration of the need for relatedness. Evaluating self-construals can help predict the subjective well-being of high-functioning individuals with ASD. Moreover, the Self-Construal Scale may be useful for understanding the heterogeneous phenotypes of ASD, based on its association with autistic symptoms during preschool years, suggesting that the scale is a potential tool to develop efficient interventions for high-functioning individuals with ASD. Autism Res 2020, 13: 947-958. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Autism Spectrum Disorders (ASD) are a group of disorders presenting a variety of symptoms and biological origins that can complicate choosing an intervention best suited for improving well-being. Results indicate that a self-construal scale could help understand individuals with high-functioning ASD by independent and interdependent self-construals that are associated with ASD symptoms during preschool years and adult subjective well-being. Our findings suggest that this scale can help understand ASD and select appropriate interventions.

Potential Risk of Virus Carryover by Fabrics of Personal Protective Gowns.

Personal protective gowns and coveralls are classified based on barrier efficiency that validates protection from fluid penetration under certain pressures. Materials standardized in this system have been found suitable for emergency medical practices confronting highly contagious diseases. Nevertheless, adhesion of blood, and body fluids from virus-infected patients to the surface of protective clothing still imposes a risk of pathogen transmission in the process of doffing, or undressing. We performed a small-scale experiment to test the possibility of infectious virus carryover on the surface of different fabrics used in commercially available protective gowns. Application of a lentivirus vector that expresses green fluorescent protein allowed easy monitoring of infectious viral loads on fabrics. Results indicate that fabrics of level-3 surgical gowns serve better to reduce virus transmission compared to fabrics of chemical protective clothing with the same or higher barrier efficiency. Analysis of sliding angles provided indexes of fluid repellency, which were inversely related to virus carryover potentials. Droplets of infectious body fluids may easily roll off fabrics with water-repellent finishing. Thus, virus carryover is a measurable risk factor to be considered for better choice of personal protective clothing.
