Traditional Buddhist Mindfulness Versus Secular Mindfulness-Based Cognitive Therapy for Residual Depressive Symptoms in Patients Treated for Depressive Disorder
The effect of previous team environment on the current motivation in Japanese varsity soccer players
Introduction Sport psychologists have investigated the effect of team environments on athletes' performance and mental health, revealing that team environments played salient roles in forming athletes' psychological processes. Currently, the scholars' interests are towards the effect of the current team environments the athletes are immersed in, and the effect of their past has not gained as much attention. Given that research on social psycholog…
Machine Learning Culture
Research in cultural differences generally follow top-down, theoretical approaches. This has overrepresented theories (such as individualism-collectivism) derived mainly from Western-centric observations of cultural phenomenon. We present an alternative, exploratory approach: machine learning for classifying participants’ cultural membership on international surveys. Using Wave 6 of the World Values Survey, we show that these models, paired with …
Unlocking mathematical potential through school-based language learning
This study explores the association between school-based foreign language (FL) instruction and mathematical achievement among 15-year-old students, using data from the 2018 Programme for International Student Assessment (PISA). Two complementary analyses were conducted: a large-scale model ( n = 300,656) examining the relationship between time spent in FL learning and maths performance across 73 countries and a machine learning (ML) approach (ran…
Music consumption and uses in Japan
This research investigates the relationship between music consumption and cultural dimensions within a Japanese context. Since Japan is the second largest music market globally, it is surprising that there is little focus on those factors often examined in cross-cultural research that might mean Western findings do not extrapolate well. A questionnaire using established measures of tightness–looseness, relational mobility, and ideal affect was us…
Vertical Transmission of Prosociality
Prosocial behavior is essential for human species such that it is expected in every culture. One way to sustain this positive behavior is through successful transfer where the later generation maintains prosociality as cultural information relevant to prosocial behavior. Informed by the cultural dynamics perspective, the current study focused on the microlevel phenomena and examined the mechanism of vertical transmission of prosociality from pare…
Can learning a new language make you better at maths? A meta-analysis of foreign language learning and numeracy skills during early adolescence
This systematic review and meta-analysis explore the correlation between foreign language instruction and mathematical skills in young adolescents, highlighting the significance of high school mathematical education and the adaptability of the adolescent brain. Focused on students starting second language programs between ages 8 and 13, following PRISMA guidelines, this review included 25 studies (1978–2020) with 785,552 participants. Using a ran…
Geopolitics in Language
This paper investigates how the historical and geopolitical relationship between China and Japan has shaped collective psychology. Using language‐based methods across three domains—public sentiment, political discourse, and academic literature—we conducted three complementary analyses. First, word embedding techniques applied to two large‐scale Chinese text corpora show that sentiment toward Japan improved from the 1950s to 1980s before declining…
How culture shapes community resilience
This paper proposes and explores a cultural model of community resilience to climate‐related disasters in two coastal villages in Indonesia. Through a case‐based research approach, we conducted interviews and focus groups with a total of 30 community members and leaders to uncover the underlying processes through which culture plays a critical role in community resilience. Our analyses identified local indigenous belief systems and practices that…
Internationalising imperatives and decolonising aspirations
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 initi…
Sea-level rise and mental health among coastal communities
This is the first large-scale empirical study examining the impact of sea-level rise induced by climate change on mental health outcomes among coastal communities. The study focuses on Bangladesh, a country severely affected by salinity ingress, flood risks, and agricultural damage due to sea-level changes. Participants ( n = 1,200) randomly selected from three coastal regions each having high, moderate, or low vulnerability to sea-level rise wer…
The Effects of Large-Scale Social Movements on Language Attitudes
Speakers with standard accents are typically judged more favorably than non-standard speakers, but this may shift in response to perceived intergroup conflict with ethnolinguistic outgroups. Three studies were conducted to examine how large-scale social movements may impact language attitudes in Hong Kong. Attitudes toward standard-accented and non-standard-accented Cantonese and Mandarin were collected across four instances in 2013 and 2015 (pre…

Individualism with Chinese characteristics? Discerning cultural shifts in China using 50 years of printed texts
This project examined cultural changes in terms of individualism-collectivism in China between 1950 and 1999 focusing on cultural associations that are discernible through analysis of language use. Drawing on algorithms in natural language processing (NLP) that numerically represent word meanings in a high-dimensional space, we examined patterns of word similarity for words indicating individualism and collectivism in Chinese. This methodology en…
Acculturation Coping Leads to Heightened Sensitivity to Socially Hurtful Events
This research examined the hypothesis that challenging experiences in acculturation may lead to heightened reactivity to socially hurtful events. Study 1 found that compared to a prime of acculturating to a similar foreign culture, priming acculturation to a distant culture (indicating more challenges) led to greater reported pain toward hurtful interpersonal events. Study 2 examined whether foreign students in the U.K. and immigrants in the U.S.…
Is positive emotion an amplifier or a buffer? It depends
Positive emotions have been shown to shape individuals' reactions to intergroup conflicts, but the exact mechanism remains unknown. The current research hypothesizes that the impact of positive emotions would be moderated by dialectical thinking: beliefs about accepting contradiction and change. Experiencing positive emotions in an intergroup conflict may be perceived as unacceptable and evokes discomfort among nondialectical individuals, amplify…
Anxious? Just Google it
Records of Internet search are increasingly used in social science research. Three studies reported here tested (a) whether population-level anxiety is reflected in Internet search data and (b) the socioecological and cultural factors of anxiety. Using data from Japan, we found that the Google search rates of anxiety are associated with self-reported anxiety (Study 1), and that the anxiety search rates increased following a major disaster (Study …
Monitoring Moral Virtue
Literature indicates that people tend to judge the moral transgressions committed by out-group members more severely than those of in-group members. However, these transgressions often conflate a moral transgression with some form of intergroup harm. There is little research examining in-group versus out-group transgressions of harmless offenses, which violate moral standards that bind people together (binding foundations). As these moral standar…
Culture and Decision Making
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, where…
Culture and Self-Esteem Over Time
Self-esteem is increasing in the United States according to temporal meta-analyses of the Rosenberg Self-Esteem Scale. However, it remains unclear whether this trend reflects broad social ecological shifts toward urban, affluent, and technologically advanced or a unique cultural history. A temporal meta-analysis of self-esteem was conducted in Australia. Australia shares social ecological and cultural similarities with the United States. On the o…
Is Trusting Others Related to Better Health? An Investigation of Older Adults Across Six Non-Western Countries
Generalized trust reflects whether individuals extend their trust to others in general and is important to health and well-being. This study examined the predictive effect of generalized trust on health, happiness, life satisfaction, health behaviors, and illnesses among older adults residing in six non-Western countries. We utilized a recent multinational dataset collected by the World Health Organization that included measures of generalized tr…
Social Identity and Attitudes Toward Cultural Diversity
Prior research indicates that there may be a disharmonious relationship between positive attitudes toward ethnic and cultural diversity and social identity within a socially dominant group. Recent work in cultural psychology, however, has implied that this disharmonious relationship may be confined to a specific representation of social identity. This research examined this possibility. Study 1 ( N = 51,238) found that the negative association be…
The Association Between Generalized Trust and Physical and Psychological Health Across Societies
Relational Mobility Increases Social (but Not Other) Risk Propensity
In recent years, we have witnessed a resurgent focus on ecological features, especially various forms of mobility that afford social psychological processes. Extending this work, the current research examined whether relational mobility affects risk propensity. We conducted three studies using both correlational (Studies 1 and 3) and experimental (Study 2) methods. Results provide support for the hypothesis that perceptions of relational mobility…
Social Class Predicts Generalized Trust But Only in Wealthy Societies
This research examined the relationship between social class and generalized trust, or a belief that others have a benign intention in social interactions, in a diverse set of societies represented in the World Values Survey. The strength of the relationship varied significantly across societies: Although social class was a positive predictor of generalized trust in wealthy countries, as reported in past research, among less wealthy countries soc…

Changes in Chinese Culture as Examined Through Changes in Personal Pronoun Usage
For the last several decades, Chinese society has experienced transformative changes in its social ecology. Is Chinese culture more individualistic today as a result? The current research examined this question by cross-temporally examining the usage of Chinese personal pronouns associated with individualism-collectivism. A Chinese corpus encompassing the period from 1950 to 2008 was analyzed using the Google Ngram Viewer. Cross-temporal changes …

In Search of East Asian Self-Enhancement
A meta-analysis of published cross-cultural studies of self-enhancement reveals pervasive and pronounced differences between East Asians and Westerners. Across 91 comparisons, the average cross-cultural effect was d = .84. The effect emerged in all 30 methods, except for comparisons of implicit self-esteem. Within cultures, Westerners showed a clear self-serving bias (d = .87), whereas East Asians did not (d = -.01), with Asian Americans falling …

Are Cultures Becoming Individualistic? A Cross-Temporal Comparison of Individualism–Collectivism in the United States and Japan
Individualism–collectivism is one of the best researched dimensions of culture in psychology. One frequently asked but underexamined question regards its cross-temporal changes: Are cultures becoming individualistic? One influential theory of cultural change, modernization theory, predicts the rise of individualism as a consequence of economic growth. Findings from past research are generally consistent with this theory, but there is also a body …
Power Distance Predicts Gender Differences in Math Performance Across Societies
In societies that oppose social inequality (low power distance societies), intergroup social comparison is relatively more prevalent. However, with an intergroup comparison focus, differences between groups are more salient and self-stereotyping more likely. Consequently, gender stereotypes regarding math may be relatively more consequential in low relative to high power distance societies. To examine this hypothesis, results from a standardized …
