Voluntary frontier settlement and independent agency within China

Voluntary frontier settlement has led to independent agency in Western and a few non-Western societies. This study suggests that Northeast China was constructed as a new region with voluntary frontier settlers during 1860-1920, and examined whether voluntary frontier settlement predicted individualistic differences by comparing inhabitants from Northeast China (N = 479) to those in contrast region where their ancestors originated (N = 520) with multiple cultural tasks. Results showed that inhabitants of Northeast China were higher in self-reported individualism and happiness related to more socially disengaging emotions, and fewer in-group favoritism and less holistic thought compared to the inhabitants of North China. Overall, this suggests that voluntary frontier settlement played an important role in the individualistic differences between Northeast China and North China.

Life is viewed as better for minorities in places with more variable habitats

Places differ in how livable they are perceived to be for minority groups. But why? We pursue an explanation through the lens of natural habitat variability (varying day length, temperature, and daily precipitation over the course of the year). Uncertainty reduction theory, flexible systems theory, and climato-economic theory offer different explanations for how habitat variability influences mindsets about racial and ethnic minorities, gays and lesbians, foreign immigrants, and people with intellectual disabilities. To test our hypotheses, we analyzed the perceived livability of the place of residence for these minority groups by 1,332,558 native inhabitants from 163 countries. Our results support the theoretical notion that variable habitats foster flexible psychosocial systems. Minorities are viewed to have better livability in places with more variable habitats. Economic affluence reinforces this trend, and the interaction effect is mediated by the quality of governance. These country-level findings (R2 ≈ 0.52) demonstrate construct, concurrent, convergent, divergent, substantive, and forecast validity. They significantly overshadow effects of individual-level characteristics and mindsets (R2 ≈ 0.03). Habitat equations predicting perceived local livability for minorities during one period (2010-2015) forecast up to 75 percent of the extent to which minorities in each of the four hemispheres of the Earth are perceived to be living in a good place at a subsequent period (2016-2020).

Warmth and Control: Examining the Associations between Chinese Parenting Behaviors and Children's Academic Performance in Different Parent-Child Dyads

Few studies have comprehensively examined the reciprocal relation between specific parenting practices and children's academic performance across parent and child gender. The present study investigated the bidirectional associations between parental warmth/control and children's academic performance using a three-wave longitudinal multi-informant design. A total of 814 families (Mchild age = 10.36 years; SD = 1.22, 57% girls) participated in the study. Results of the random-intercept cross-lagged models indicated that paternal warmth promoted children's academic performance at the between-family level, whereas maternal warmth promoted children's academic performance at the within-family level. Interestingly, paternal control predicted better academic performance in boys over time (i.e., the within-family level) but contributed to girls' worse academic performance than others (i.e., the between-family level). These results highlighted the gender-universal effects of parental warmth and the gender-specific effects of parental control on child academic performance in the Chinese context. These findings underscored the necessity of considering parent-child dynamics across different parent-child gender dyads.

Second Thoughts About Culture and Cause: Why and How Do the Chinese and Americans Differ in Causal Attributions?

Academic AbstractCurrent theories on dispositional-situational attributions suggest that East Asians' attributions are more external compared to Westerners. However, empirical studies yield mixed findings. I reflect on historical, philosophical, and sociological resources in China and the United States to address this inconsistency. This paper (a) proposes a new attributional dimension borrowed from Chinese philosophy-human- versus heaven-determined (-); (b) postulates that the Chinese are more likely to make internal human-determined attributions than Americans, whereas Americans are more inclined to make internal and external heaven-determined attributions than the Chinese; (c) reviews the existing literature to examine the extent to which this theory is evidenced and determine aspects remaining untested; and (d) discusses the generalizability to other cultures and directions for further research. Notably, "heaven-determined" is interpreted metaphorically (not religiously). Beyond dispositional-situational theory, this paper spotlights another meaningful pathway for constructing cross-cultural theory: The Chinese emphasize human determinism more than Americans.Public AbstractWhy do I succeed or fail? Why do people help or harm others? Members of different cultures may provide different answers to such questions-known in psychology as "causal attributions." A popular belief in psychology is that East Asians are more likely than Westerners to consider external factors-in other words, environmental/outside factors-as causes of behaviors and outcomes. In this paper, I challenge this prevailing theory and propose an alternative, drawing on cultural resources and social realities of China and the United States. When explaining why something happens, the Chinese may focus more on average than Americans do on internal causes determined by humans (e.g., effort, motivation, attitude, skill, and strategy), whereas Americans may focus more on average than the Chinese do on causes that are not determined by humans (e.g., aptitude, genes, gender, race/ethnicity, physiological characteristics, luck, and supernatural force). More research is needed to test this postulation.

Grain Self-Sufficiency in Guangdong, China: Current Trends and Future Perspectives

The rising number of disturbances caused by natural hazards, epidemics, and international conflicts seriously threatens global agriculture and food systems. In order to combat the increasing uncertainty, the Chinese government proposed a "dual circulation" strategy, which puts forward a new requirement of promoting self-sufficiency. Among various food categories, grain serves as a cornerstone for sustaining human life during public crises. Guangdong Province is one of the most economically developed and highly densely populated regions in China; therefore, it faces significant pressure to enhance food security. This study investigates the spatial and temporal patterns of the rate of grain self-sufficiency (RSSG) at the county levels in Guangdong Province from 2014 to 2023. The findings reveal the following: (1) rice remains the predominant grain crop, with its sown area and production consistently accounting for over 75%; (2) the RSSG is 28.14% on average, which is lower than the governmental goal of 30%; (3) the RSSG has significant regional disparities and distinct agglomeration patterns; and (4) scenario simulations indicate that grain yield improvement and grain loss reduction have the potential to promote the RSSG to 34.14%. Based on the research findings, this paper proposes the following policy recommendations: (1) prioritize farmland preservation and implement the "storing grain in the land" strategy to ensure food supply; (2) adopt advanced agricultural technologies under the "storing grain in the technology" strategy to improve grain yield; (3) reduce grain loss by strengthening disaster prevention, improving storage management, and enhancing storage efficiency; and (4) strengthen interdepartmental coordination. The integrated application of these strategies will help Guangdong Province enhance its grain self-sufficiency, ensure food security, and contribute to the achievement of national food security goals.

Mapping the landscape of land inequality: A multi-level, data-driven exploration of land inequality in South Korea's urban and regional spheres

Land inequality has emerged as a defining challenge in contemporary societies, shaping patterns of wealth concentration and socioeconomic stratification. This study critically examines the persistence and intensification of land disparities in South Korea between 2018 and 2022, applying a data-driven methodological framework to uncover structural inequalities embedded within the spatial distribution of land wealth. The analysis reveals a stark divergence in property values and ownership patterns, reinforcing existing socioeconomic divisions and highlighting the spatial entrenchment of privilege. The implications of these disparities extend beyond economic inequities, raising concerns about long-term social stability and policy effectiveness in mitigating wealth concentration. This study underscores the necessity of policy interventions to address the compounding effects of land inequality. By advancing an empirical approach to the study of land concentration, this research contributes to broader discussions on spatial inequality, economic polarization, and sustainable urban development.

Cultural Differences in Vicarious Optimism

Prosocial behavior is affected by the beliefs people have about others. The maintenance of these beliefs is biased: people are vicariously optimistic when updating beliefs about the future of others they care about. This vicarious optimism influences prosocial behavior and might be shaped by the culture people live in. We investigated this question by measuring learning from good and bad news for oneself, friends, and strangers in a pre-registered study of Chinese and American participants (N = 963). American participants showed a stronger bias for better-than-expected "good news" over worse-than-expected "bad news" when learning about themselves (optimism bias) and others (vicarious optimism) compared to Chinese participants. Chinese participants showed vicarious optimism only when learning about a friend, while American participants showed the most vicarious optimism when learning about an identifiable stranger. Our results provide evidence that culture might shape social behavior by biasing learning about the future of others.

How Age and Culture Influence Cognition: A Lifespan Developmental Perspective

It has long been assumed that cognitive aging is a universal phenomenon. However, increasing evidence substantiates the importance of individual differences in cognitive aging. How do experiential factors related to culture shape developmental trajectories of cognition? We propose a new model examining how age and culture influence cognitive processes, building on past models and expanding upon them to incorporate a lifespan developmental perspective. The current model posits that how age and culture interact to influence cognition depends on (a) the extent to which the cognitive task relies on top-down or bottom-up processes, and (b) for more top-down processes, the level of cognitive resources required to perform the task. To assess the validity of the model, we review literature not only from adulthood but also childhood, making this the first model to adopt a lifespan perspective in the study of culture and cognition. The current work advances understanding of cognitive aging by delineating the combined effects of biological aging processes, assumed to apply across cultures, and culture-dependent experiential aging processes, which reflect unique cultural experiences throughout one's lifespan. This approach enables understanding of comprehensive potential mechanisms that underlie the influence of culture on cognitive development across life stages.

Resolving differences in digestion features of cooked rice and wheat noodles: A view from starch multiscale structure

The staple foods play an important role in providing energy in the human daily diet. Wheat is the main staple food in northern China, rice in southern China, and the different staple food patterns between the north and south result in health disparities. Therefore, analyzing the differences in the digestion of staple foods are particularly important for understanding the digestive energy supply of staple foods. The firmer gel network structure, thicker crystalline lamellae, more V-type crystallites, higher degree of helical structure, and short-range order in cooked rice impeded the diffusion of amylase on the starch surface and inhibited the amylase-starch binding, leading to a lower rate of enzymatic hydrolysis of starch molecular chains and significantly higher content of RS than wheat noodles (P < 0.05). The different processing methods of cooked rice and wheat noodles influenced the multiscale structure of starch and thus the rate of digestion.

Developing the Chinese version of the Index of Sojourner Social Support: the roles of socio-emotional and instrumental support in internal migrant university students

Introduction

This study aims to validate the Index of Sojourner Social Support (ISSS)-a widely-used scale for measuring social support in cross-cultural (including cross-national and internal) migrations-in Chinese contexts among internal migrant university students and explore how such support can facilitate their psychological adjustment.

Methods

One thousand six hundred ninety-two university students who migrated from all around China to the city of Shanghai participated in this study. The ISSS was translated according to strict procedures. Item analysis, confirmatory factor analysis (CFA), reliability analysis, measurement equivalence test, criterion validity test, and incremental validity test of the Chinese version of the ISSS (ISSS-C) were carried out.

Results

The ISSS-C generated by this study had two dimensions (socio-emotional support and instrumental support) of 18 items. The model fit was excellent (χ2/df = 5.64, CFI = 0.96, TLI = 0.95, SRMR = 0.03, and RMSEA = 0.06). The McDonald's omegas for its two subscales were both 0.96. The measurement equivalence of the ISSS-C and criterion validity were also excellent. Instrumental support significantly influenced students' psychological adjustment to the host culture, partially establishing incremental validity for the scale.

Discussion

The ISSS-C exhibits good psychometric properties and is appropriate for measuring social support perceived by migrant university students in Chinese cultural contexts. Further, instrumental support can assist them in psychologically adjusting well to local environments.

Unpacking interplays between competitiveness, cooperativeness, and social comparison orientation: A network psychometric approach and replication

Emerging evidence highlights the role of social comparison in competition and cooperation, yet the dynamics among competitiveness, cooperativeness, and social comparison orientation (SCO) remain underexplored. In the present study, we sought to unravel these complex interplays employing graphical Gaussian models (GGMs) and characterize the network structures utilizing cross-sectional data derived from 1073 Chinese participants. A pre-registered independent sample (n = 1348) served to examine the replicability and robustness of our initial findings. Moreover, we explored the Bayesian networks (i.e., directed acyclic graphs) to delve into their probabilistic directed dependencies. Our analysis identified an interpersonal co-opetition network where SCO bridges competitiveness and cooperativeness, emphasizing the key influence of the desire to surpass others. We also found a significant gender effect on the levels of these orientations but not on the network patterns. Additionally, the replication sample offered validation for the resultant network structure and its key nodes. In sum, these findings provide a new insight into the symbiotic relationship between competitiveness and cooperativeness within the framework of social comparison, offering significant theoretical and practical implications.

A novel MADM model integrating hybrid information for evaluating the development prospects of urban new energy vehicles

As an effective approach to mitigating urban environmental issues, New Energy Vehicles (NEVs) have become a focal point of research regarding their current development status and future prospects in China. Addressing the significant disparities in the development of the NEVs industry across different cities, this study focuses on ten typical Chinese cities and develops a novel multi-attribute decision-making (MADM) framework to evaluate the prospects of NEVs promotion in these cities. The study first establishes a comprehensive indicator system that covers key dimensions such as economy, policy support, infrastructure, technological innovation, and environment, encompassing five different types of evaluation information. This system incorporates five different types of evaluation information: exact numbers, interval numbers, triangular fuzzy numbers, hesitant fuzzy numbers, and probabilistic linguistic term sets (PLTS), enhancing the framework's ability to handle diverse data types. Subsequently, the improved entropy (IEntropy) weight method is employed to determine the objective weights of the evaluation indicators. These objective weights are then integrated with the Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method, facilitating a structured group decision-making approach that synthesizes hybrid evaluation information. Based on modular thinking, hybrid evaluation information is synthesized to evaluate and rank the NEVs development prospects of each city. Sensitivity analysis and comparative analysis further demonstrate the robustness and reliability of the proposed MADM framework. The ranking results indicate that Shanghai and Guangzhou lead in NEVs promotion, while cities like Harbin and Zhengzhou lag behind. Based on these findings, the study proposes targeted policy recommendations to promote the sustainable development of the NEVs industry in major Chinese cities.

Cultural and personal values interact to predict divorce

We investigate the role of values in motivating the dissolution of marriage. Drawing on comprehensive value frameworks, we study how cultural values explain cross-national variation in divorce, how personal values explain further variation within nations, and how the two value systems interact together. In three archival studies, including more than 100,000 participants from over 55 countries, we study attitudes toward divorce as well as actual divorce. We found that divorce was more justifiable and likely in nations emphasizing autonomy values, and among individuals ascribing importance to self-direction, stimulation, and hedonism values. Divorce was less justifiable and likely in nations emphasizing embeddedness values, and among individuals ascribing importance to tradition and conformity values. Overall, the impact of personal values was stronger the more the culture emphasizes autonomy (vs. embeddedness) values. Understanding the role of values in divorce may inform individuals as to the values they desire in their future spouses.

Exploring the ecological relationship between temperature and prosocial behaviour: A geographical and temporal analysis

Previous research on the link between temperature and prosociality has produced mixed findings. A recent meta-analysis focusing on laboratory-based research concluded that the effect was null, a conclusion that was subject to low ecological validity. This paper complements the discussion by investigating the link between ambient temperature and three indicators of real-life prosociality in 164 regions over 14 years. The between-regional comparison probes the relationship over a wide range of thermal conditions, whereas the within-regional temporal comparison draws this literature to the real-life problem of global warming. Bayesian analysis indicates that temperature is linked to helping strangers, but not volunteerism or charity donation. Hotter regions have more helping respondents than colder regions, and as a region warms, it also records more helping respondents. The positive link between temperature and helping is in line with social thermoregulation theory, but it is also subject to alternative explanations from a cultural perspective and sociological perspective. We conclude that it is unrealistic to expect temperature to have the same effect on all prosocial acts without considering contextual factors and the underlying mechanisms. Our findings call for a nuanced view concerning the effect of temperature on prosociality, which awaits verification by rigorous research designs.

How Culture Shapes the Early Development of Essentialist Beliefs

People represent many categories and their features as determined by intrinsic essences. These essentialist beliefs reflect biased views of the world that can hinder scientific reasoning and contribute to social prejudice. To consider the extent to which such essentialist views originate from culturally-situated processes, the present study tested the developmental trajectories of essentialist beliefs among children growing up in the United States and China (N = 531; ages 3-6). Essentialist beliefs emerged across early childhood in both communities, but their instantiation and trajectories varied across cultures. In the sample from the United States (but not from China), essentialist beliefs that categories and their features are fixed-at-birth and inflexible increased across age. On the other hand, in the sample from China, children held stronger beliefs that categories are objective and explanatory and viewed them as more homogenous with age. Children sampled from these two contexts also showed variation in basic explanatory, linguistic, and inferential processes, suggesting that cultural variation in the development of essentialism across childhood might reflect variation in the basic conceptual biases that children rely on to build intuitive theories of the world.

Analysis on the spatiotemporal pattern and driving force of the spatial deviation index of grain and economy in counties in China

Studying the spatial relationship and driving forces between grain production and economic development in China can assist in the coordinated development of economic growth and grain production in both China and other developing countries. Based on panel data from 2000 to 2019 covering 2018 county-level units in China, this study comprehensively investigated the spatial distribution, spatial differences, dynamic evolution of distribution, and driving factors of China's county-level spatial deviation index of grain and economy (SDIGE) using methods such as the standard deviation ellipse method, the three-stage nested decomposition of Theil index, kernel density estimation, and geographically weighted regression (GWR) model. The results show that (1) from 2000 to 2019, China's SDIGE showed a development trend of "up-down-up," and the highest SDIGE was in the northeast region, the lowest in the east region, and the spatial pattern of "high in the northeast-low in the east coast" was increasingly prominent. (2) In terms of spatial difference, the overall difference of SDIGE in China from 2000 to 2019 showed a rising trend of development; The average contribution rate of the regional difference to the overall difference was the lowest, maintained at about 17.82%; The average contribution rate of intra city and inter-county differences to the overall difference is the highest, which is about 34.20%. (3) In terms of the driving force, the level of economic development hurts SDIGE, while population density, industrial structure, fiscal decentralisation, and terrain fluctuation have a positive and negative impact on SDIGE. To alleviate the imbalance between China's economic development and grain production, it is necessary to implement differentiated policy measures tailored to the specific characteristics of different regions to assist agricultural producers and enhance the stability of grain production.

Rethinking peer influence and risk taking: A strengths-based approach to adolescence in a new era

The ways that psychopathology manifests in adolescence have shifted dramatically over the past twenty-five years, with rates of many externalizing behaviors declining substantially while rates of anxiety and depressive disorders have skyrocketed. This paper argues that understanding these changes requires rethinking the field's historically somewhat negative views of intense peer connections, peer influences, and adolescent risk-taking behavior. It is argued that intense peer connections are critical to development, and that peer influence and risk taking have important, often overlooked, adaptive components. The shift in observed manifestations of adolescent psychopathology over this period can be viewed at least partly in terms of a shift away from strong peer connections and toward greater risk aversion. Implications for research and intervention based on a focus on the adaptive aspects of peer influences and risk taking are discussed.

Interdependency or submission to authority? The impacts of horizontal and vertical collectivist orientation on vaccine attitudes in mainland China

Culture has a profound impact on preventive measures during the COVID-19 pandemic. Previous research has revealed that collectivism is associated with more effective responses to COVID-19 on the national or regional level. However, the impact of different components of collectivist orientation on vaccine attitudes remains insufficiently explored on the individual level. Two survey studies conducted in August 2021 in mainland China consistently found that individual-level horizontal collectivist orientation, rather than vertical collectivist orientation, was linked with more favourable vaccine attitudes. Specifically, Study 1 (N = 731) indicated that horizontal collectivist orientation was positive associated with vaccination intention indirectly via risk perception, and horizontal collectivist orientation was also positively associated with vaccination persuasion both directly and indirectly via risk perception. Study 2 (N = 1481), employing multilevel modelling, demonstrated that the link between horizontal collectivist orientation and confidence in vaccines remained robust regardless of provincial-level variations in socioeconomic development and cultural tightness. These findings convergently suggest that the positive vaccine attitudes among mainland Chinese are primarily driven by an amplified risk perception due to concern for others, rather than submission to authority.

Culturomics: Taking the cross-scale, interdisciplinary science of culture into the next decade

Culture is a complex topic involving a comprehensive representation of human institutions, social customs, norms, and lifestyles. Over the past half-century, the methods of cultural studies have improved dramatically in the depth of the research questions posed. However, most contemporary research on cultural issues is conducted from a single perspective, which fails to account for the holistic and extensive nature of culture. The development of culture is influenced by various factors, encompassing not only the humanistic environment but also factors related to the natural environment and socio-economic conditions. Hence, culture involves multiple concepts with associated levels and dimensions, such as genes, molecules, brains, individuals, groups, institutions, societies, and political environments. Therefore, we propose the concept of Culturomics, a cross-level, interdisciplinary science that studies human behavior and cultural representation in high-order space. Under this concept, it is necessary to find new methods to compare multidimensional data from different levels directly. In this paper, we first review past cultural studies, then introduce the concept, research content, and methodology of Culturomics, and discuss future directions for this field.

Where Is Capitalism? Unmasking Its Hidden Role in Psychology

PUBLIC ABSTRACT

Our thoughts, behaviors, and well-being are deeply influenced by the economic system we live in-capitalism. While psychologists have explored capitalist ideologies like neoliberalism, they often overlook capitalism's core foundations driving inequality. This work argues that capitalism, rooted in Western colonial history, generates powerful cultural narratives prioritizing profit, competition, and private ownership. These capitalist principles manifest as pervasive societal mindsets obsessed with personal gain, viewing life as a zero-sum rivalry, and deriving self-worth from possessions. Collectively, they breed an individualistic syndrome of selfish striving at the expense of community. By understanding how these capitalist cultural forces psychologically shape us, maintaining oppressive societal hierarchies, we can reimagine economic systems that truly uplift the human spirit across all peoples and the planet we share. Unveiling capitalism's influence is crucial to recover from its alienating effects and envision liberating alternatives.

Strong-ties and weak-ties rationalities: toward a mental model of the consequences of kinship intensity

There is growing evidence of the connection between variations in kinship intensity and cross-cultural differences in psychological traits. Contributing to this literature on kinship intensity, we put forward a mental model to explain the enduring connection between ancestral niche and psychological traits. Our model posits that two primary orientations or dispositions-strong-ties and weak-ties rationalities-have co-evolved with our ancestral niches to perpetuate-by internalizing and reproducing-the social structure (such as preferences for certain attitudes, values, and beliefs) of the ancestral niche. The findings from 1,291 participants across four societies-China, India, Taiwan, and the United States-support our hypothesis that strong-ties (weak-ties) rationalities, when activated, will endorse strong-tie (weak-ties) values and beliefs. This proposed model contributes to the toolbox of cultural and cross-cultural psychology in a twofold sense: First, in addition to the index of kinship intensity, it offers a measure of kin-based rationality as another predictor of psychological traits; second, it renders intelligible the niche and rationality disconnect prevalent in the globalizing era.

We Need Tough Brothers and Sisters in a Tight World: Cultural Tightness Leads to a Preference for Dominant and Muscular Leaders

Cultural tightness is characterized by strong norms and harsh punishments for deviant behaviors. We hypothesized that followers in tight (vs. loose) cultures would more strongly prefer muscular leaders. This hypothesis was confirmed across seven studies (N = 1,615) employing samples from the United States, the United Kingdom, and China. Using actual political leaders, we demonstrated that the tighter the state's culture was, the more muscular the elected governor was (Study 1). Temporarily situating participants in a tight (vs. loose) culture made them select a leader higher on muscularity but not on body fat, and the effects obtained occurred for both male and female leaders (Studies 2-3B). In addition, we demonstrated the mediating role of authoritarianism and a preference for a dominant leadership in this process (Studies 4-5B). These results demonstrate the importance of considering the interface between culture and the physical appearance of leaders.

Methodological concerns underlying a lack of evidence for cultural heterogeneity in the replication of psychological effects

The multi-site replication study, Many Labs 2, concluded that sample location and setting did not substantially affect the replicability of findings. Here, we examine theoretical and methodological considerations for a subset of the analyses, namely exploratory tests of heterogeneity in the replicability of studies between "WEIRD and less-WEIRD cultures". We conducted a review of literature citing the study, a re-examination of the existing cultural variability, a power stimulation for detecting cultural heterogeneity, and re-analyses of the original exploratory tests. Findings indicate little cultural variability and low power to detect cultural heterogeneity effects in the Many Labs 2 data, yet the literature review indicates the study is cited regarding the moderating role of culture. Our reanalysis of the data found that using different operationalizations of culture slightly increased effect sizes but did not substantially alter the conclusions of Many Labs 2. Future studies of cultural heterogeneity can be improved with theoretical consideration of which effects and which cultures are likely to show variation as well as a priori methodological planning for appropriate operationalizations of culture and sufficient power to detect effects.

When Interdependence Backfires: The Coronavirus Infected Three Times More People in Rice-Farming Areas During Chinese New Year

Interdependent cultures around the world have generally controlled COVID-19 better. We tested this pattern in China based on the rice theory, which argues that historically rice-farming regions of China are more interdependent than wheat-farming areas. Unlike earlier findings, rice-farming areas suffered more COVID-19 cases in the early days of the outbreak. We suspected this happened because the outbreak fell on Chinese New Year, and people in rice areas felt more pressure to visit family and friends. We found historical evidence that people in rice areas visit more family and friends for Chinese New Year than people in wheat areas. In 2020, rice areas also saw more New Year travel. Regional differences in social visits were correlated with COVID-19 spread. These results reveal an exception to the general idea that interdependent culture helps cultures contain COVID-19. When relational duties conflict with public health, interdependence can lead to more spread of disease.

Why wearing a yellow hat is impossible: Chinese and U.S. children's possibility judgments

When thinking about possibility, one can consider both epistemic and deontic principles (i.e., physical possibility and permissibility). Cultural influences may lead individuals to weigh epistemic and deontic obligations differently; developing possibility conceptions are therefore positioned to be affected by cultural surroundings. Across two studies, 251 U.S. and Chinese 4-, 6-, and 8-year-olds sampled from major metropolitan areas in Texas and the Hubei, Sichuan, Gansu, and Guangdong Provinces judged the possibility of impossible, improbable, and ordinary events. Across cultures and ages, children judged ordinary events as possible and impossible events as impossible; cultural differences emerged in developing conceptions of improbable events. Whereas U.S. children became more likely to judge these events possible with age, Chinese children's judgments remained consistent with age: Chinese 4- to 8-year-olds judged these events to be possible ∼25% of the time. In Study 2, to test whether this difference was attributable to differential prioritization of epistemic versus deontic constraints, children also judged whether each event was an epistemic violation (i.e., required magic to happen) and a deontic violation (i.e., would result in someone getting in trouble). With age, epistemic judgments were increasingly predictive of possibility judgments for improbable events for U.S. children, and decreasingly so for Chinese children. Contrary to our predictions, deontic judgments were not predictive. We propose that cultural valuation of norms might shape children's developing intuitions about possibility. We discuss our findings in light of three accounts of possibility conceptions, suggesting ways to integrate cultural context into each.

Morality and political economy from the vantage point of economics

Political disagreement is increasingly moral, rather than economic, in nature, raising the question how the fields of political economy and moral psychology relate to each other. While these disciplines were initially deeply intertwined, cross-disciplinary exchange became rare throughout the 20th century. More recently, the tide has shifted again-social scientists of different backgrounds recognized that morality and politico-economic outcomes influence each other in rich bidirectional ways. Because psychologists and economists possess distinct and complementary skill sets, part of this movement consists of productive "economic imperialism"-economists leveraging their empirical toolkit to test and substantiate theories from moral psychology at scale or in the wild. To illustrate this, I present two case studies of recent economics research on prominent ideas in moral psychology. First is the theory that morality is ultimately functional-that it evolved as a form of "psychological and biological police" to enforce cooperation, such as in economic production and exchange. Second is that the structure of morality shapes political views and polarization, including on economic issues such as taxation and redistribution. I conclude from these case studies that economists have much to gain from integrating more ideas from moral psychology, and that moral psychologists will be able to make an even more compelling case if they engage with research in economics.

Influence of Confucianism and Taoism on self-construal and thinking style: an intervention study

Using original texts of Confucian and Taoist primary classics as materials, we conducted an eight-week educational intervention experiment combining classroom teaching and post-class reflection as cultural manipulation. Ninety-four sixth-grade students from three parallel mainstream classes were randomly assigned to three intervention groups, comprising two experimental groups (Confucian and Taoist values interventions) and a control group (natural science intervention). The results suggest that the Confucian intervention had a positive effect on interdependent self and holistic thinking, the Taoist intervention had a positive effect on independent self and holistic thinking, and the natural science intervention promoted analytical thinking.

Expanding the Scope of Diverse Contexts in Affective Science

The Future of Affective Science special issue covered a broad range of topics, ranging from the valuation and experience of emotions to their expression and regulation. Despite the breadth of these topics, consideration of diverse contexts was limited in that most studies relied on Western, Educated, Industrialized, Rich, and Democratic (WEIRD) samples and/or failed to explore the rich diversity present in those countries with vast population heterogeneity. We argue that a more systematic approach is essential to advance theory and research on how diverse contexts impact and interact with different components of emotion processes. Specifically, future research should compare a wider range of cultures; examine the interplay between culture, individual, and situation; and transcend the traditional Eastern/Western or WEIRD/non-WEIRD dichotomy and other group comparisons by embracing a dimensional approach to diverse contexts. We provide concrete examples of how leveraging these three approaches to expand the scope of diverse contexts can benefit the future development of affective science, a field heavily impacted by sociocultural context.

Cultural values, parenting, and child adjustment in China

To examine whether parents' cultural values are related to parenting practices and children's behavioural adjustment, mothers, fathers and children (N = 218) from two cities in China (Jinan and Shanghai) were interviewed when children were, on average, 10 years old. Mothers and fathers reported their endorsement of cultural values (individualism, collectivism, conformity), which were used to separately predict warmth and family obligation expectations reported by each parent, as well as children's report of parental psychological control, rule setting, knowledge solicitation and perceived family obligation expectations. Cross-informant (parents and child) composites of internalising and externalising behaviours were also obtained. The results showed that maternal individualism positively predicted parents' knowledge solicitation. Parental collectivism positively predicted their own warmth and family obligation expectations. Mothers' conformity positively predicted mothers' family obligation expectations, paternal warmth and children's perception of family obligation, whereas fathers' conformity only positively predicted fathers' family obligation expectations. These effects were largely consistent across regional subsamples, although mothers in Jinan were more collectivistic than mothers in Shanghai, and parents in Shanghai adopted less psychological control and more knowledge solicitation in parenting.

Reinforcement learning of altruistic punishment differs between cultures and across the lifespan

Altruistic punishment is key to establishing cooperation and maintaining social order, yet its developmental trends across cultures remain unclear. Using computational reinforcement learning models, we provided the first evidence of how social feedback dynamically influences group-biased altruistic punishment across cultures and the lifespan. Study 1 (n = 371) found that Chinese participants exhibited higher learning rates than Americans when socially incentivized to punish unfair allocations. Additionally, Chinese adults showed slower learning and less exploration when punishing ingroups than outgroups, a pattern absent in American counterparts, potentially reflecting a tendency towards ingroup favoritism that may contribute to reinforcing collectivist values. Study 2 (n = 430, aged 12-52) further showed that such ingroup favoritism develops with age. Chinese participants' learning rates for ingroup punishment decreased from adolescence into adulthood, while outgroup rates stayed constant, implying a process of cultural learning. Our findings highlight cultural and age-related variations in altruistic punishment learning, with implications for social reinforcement learning and culturally sensitive educational practices promoting fairness and altruism.

Holistic food system innovation strategies can close up to 80% of China's domestic protein gaps while reducing global environmental impacts

China's imports of livestock feed, particularly protein-rich feeds, pose challenges to global environmental sustainability. Achieving protein self-sufficiency for food and feed in China without exceeding environmental boundaries requires integrated measures and optimization of China's food system. Here we propose holistic food system innovation strategies consisting of three components-technological innovation, integrated spatial planning and demand-side options-to reduce protein import dependency and promote global environmental sustainability. We find that food system innovations can close almost 80% of China's future protein gaps while reducing 57-85% of agricultural import-embodied environmental impacts. Deploying these innovations would also reduce greenhouse gas emissions (22-27%) and people's harmful exposure to ammonia (73-81%) compared with the baseline scenario in 2050. Technological innovations play a key role in closing protein gaps, while integrated crop-livestock spatial planning is imperative for achieving environmental and health targets.

Biogeographical ‍distributions of trickster animals

Human language encompasses almost endless potential for meaning, and folklore can theoretically incorporate themes beyond time and space. However, actual distributions of the themes are not always universal and their constraints remain unclear. Here, we specifically focused on zoological folklore and aimed to reveal what restricts the distribution of trickster animals in folklore. We applied the biogeographical methodology to 16 taxonomic categories of trickster (455 data) and real (93 090 848 data) animals obtained from large databases. Our analysis revealed that the distribution of trickster animals was restricted by their presence in the vicinity and, more importantly, the presence of their corresponding real animals. Given that the distributions of real animals are restricted by the annual mean temperature and annual precipitation, these climatic conditions indirectly affect the distribution of trickster animals. Our study, applying biogeographical methods to culture, paves the way to a deeper understanding of the interactions between ecology and culture.

Lost Food and Associated Phosphorus Footprint: Evidence from China

The environmental impacts of excessive phosphorus emissions (PE) have been widely discussed in recent years. This study aims to calculate and evaluate the phosphorus footprint (PF) of food thrown away in Chinese universities. Based on a nationwide survey involving 9192 university students from 29 provinces and 29 universities in China, the result reveals that the PF generated by food waste in Chinese university canteens was 3.209 Kt in 2018. Furthermore, it is found that meal satisfaction, gender, regional economic level, dietary culture, and years of education all have significant impacts on lost food PF. Our findings emphasize the importance of reducing food waste in university canteens, which plays a crucial role in ensuring food security and environmental protection.

Worldwide divergence of values

Social scientists have long debated the nature of cultural change in a modernizing and globalizing world. Some scholars predicted that national cultures would converge by adopting social values typical of Western democracies. Others predicted that cultural differences in values would persist or even increase over time. We test these competing predictions by analyzing survey data from 1981 to 2022 (n = 406,185) from 76 national cultures. We find evidence of global value divergence. Values emphasizing tolerance and self-expression have diverged most sharply, especially between high-income Western countries and the rest of the world. We also find that countries with similar per-capita GDP levels have held similar values over the last 40 years. Over time, however, geographic proximity has emerged as an increasingly strong correlate of value similarity, indicating that values have diverged globally but converged regionally.

Culture and self-construal in the age of globalization: an empirical inquiry based on multiple approaches

Introduction

There are three main types of culture in human society, namely, individual-oriented, relationship-oriented and social-oriented cultures. In history, there are two main positions on the relationship between culture and self-construal: the cultural determinist position and the interaction position. After analyzing literature critically, we propose that the interaction position is more persuasive than the cultural determinist position. A self-construal model was constructed from an interactionist and polycultural perspective, pointing out the relationship between three cultures and self-construal. We argue that individuals interacting with cultures in the context of globalization can develop a more integrated self-construal. The present study proposes the existence of polycultural self-construal, and aimed to explore how self-construal factors relate to cultures.

Methods

Three approaches-psychological tests, priming with cultural icons and content analysis-were used to explore mechanisms between cultures (individual-oriented, relationship-oriented, and social-oriented cultures) and self-construal. In Study 1, we recruited 460 undergraduate students as participants through campus advertising to complete three psychological tests, namely, the Cultural Identity Scale (CIS), the Marlowe-Crowne Social Approval Scale (MC-SDS), and the Polycultural Self-construal Scale (PSCS). In Study 2, we created icon materials that could prime the three cultures. The experimental process was divided into two stages: priming and measurement. First, 165 participants were presented with icon materials on the computer screen to activate the corresponding culture, and then they were asked to complete the PSCS. In Study 3, the experimental procedures were followed as for Study 2. Then the Ten Statements Test (TST) was used. Each of the 178 participants gave 10 different responses to the question of "Who am I?." Each participant's "I am …" narratives were qualitatively processed using content analysis.

Results

The individual-oriented culture mainly affects the individuality and equality factor of self-construal. The relationship-oriented culture mainly impacts the relationality factor of self-construal, while the social-oriented culture mainly affects the collectivity and equality factors of self-construal. There were no significant differences in the effects of the three cultures on the autonomy factor of self-construal. The multi-components of the polycultural self-construal are difficult to interpret based on one culture type. All three cultures have specific and shared effects on human self-construal.

The slave trade and the origins of matrilineal kinship

Matrilineal kinship systems-where descent is traced through mothers only-are present all over the world but are most concentrated in sub-Saharan Africa. We explore the relationship between exposure to Africa's external slave trades, during which millions of people were shipped from the continent during a 400-year period, and the evolution of matrilineal kinship. Scholars have hypothesized that matrilineal kinship, which is well-suited to incorporating new members, maintaining lineage continuity and insulating children from the removal of parents (particularly fathers), was an adaptive response to the slave trades. Motivated by this, we test for a connection between the slave trades and matrilineal kinship by combining historical data on an ethnic group's exposure to the slave trades and the presence of matrilineal kinship following the end of the trades. We find that the slave trades are positively associated with the subsequent presence of matrilineal kinship. The result is robust to a variety of measures of exposure to the slave trades, the inclusion of additional covariates, sensitivity analyses that remove outliers, and an instrumental variables estimator that uses a group's historical distance from the coast as an instrument. We also find evidence of a complementarity between polygyny and matrilineal kinship, which were both social responses to the disruption of the trades.

Cross-societal variation in norm enforcement systems

Across human societies, people are sometimes willing to punish norm violators. Such punishment can take the form of revenge from victims, seemingly altruistic intervention from third parties, or legitimized sanctioning from institutional representatives. Although prior work has documented cross-cultural regularities in norm enforcement, substantial variation exists in the prevalence and forms of punishment across societies. Such cross-societal variation may arise from universal psychological mechanisms responding to different socio-ecological conditions, or from cultural evolutionary processes, resulting in different norm enforcement systems. To date, empirical evidence from comparative studies across diverse societies has remained disconnected, owing to a lack of interdisciplinary integration and a prevalent tendency of empirical studies to focus on different underpinnings of variation in norm enforcement. To provide a more complete view of the shared and unique aspects of punishment across societies, we review prior research in anthropology, economics and psychology, and take a first step towards integrating the plethora of socio-ecological and cultural factors proposed to explain cross-societal variation in norm enforcement. We conclude by discussing how future cross-societal research can use diverse methodologies to illuminate key questions on the domain-specificity of punishment, the diversity of tactics supporting social norms, and their role in processes of norm change. This article is part of the theme issue 'Social norm change: drivers and consequences'.

People quasi-randomly assigned to farm rice are more collectivistic than people assigned to farm wheat

The rice theory of culture argues that the high labor demands and interdependent irrigation networks of paddy rice farming makes cultures more collectivistic than wheat-farming cultures. Despite prior evidence, proving causality is difficult because people are not randomly assigned to farm rice. In this study, we take advantage of a unique time when the Chinese government quasi-randomly assigned people to farm rice or wheat in two state farms that are otherwise nearly identical. The rice farmers show less individualism, more loyalty/nepotism toward a friend over a stranger, and more relational thought style. These results rule out confounds in tests of the rice theory, such as temperature, latitude, and historical events. The differences suggest rice-wheat cultural differences can form in a single generation.

Self- and Other-Orientation in High Rank: A Cultural Psychological Approach to Social Hierarchy

PUBLIC ABSTRACT

Social hierarchy is one fundamental aspect of human life, structuring interactions in families, teams, and entire societies. In this review, we put forward a new theory about how social hierarchy is shaped by the wider societal contexts (i.e., cultures). Comparing East Asian and Western cultural contexts, we show how culture comprises societal beliefs about who can raise to high rank (e.g., become a leader), shapes interactions between high- and low-ranking individuals (e.g., in a team), and influences human thought and behavior in social hierarchies. Overall, we find cultural similarities, in that high-ranking individuals are agentic and self-oriented in both cultural contexts. But we also find important cross-cultural differences. In East Asian cultural contexts, high-ranking individuals are also other oriented; they are also concerned about the people around them and their relationships. We close with a call to action, suggesting studying social hierarchies in more diverse cultural contexts.

The lay of the land: Associations between environmental features and personality

OBJECTIVE

Personality traits cluster across countries, regions, cities, and neighborhoods. What drives the formation of these clusters? Ecological theory suggests that physical locations shape humans' patterns of behaviors and psychological characteristics. Based on this theory, we examined whether and how differential land-cover relates to individual personality.

METHOD

We followed a preregistered three-pronged analysis approach to investigate the associations between personality (N = 2,690,878) and land-cover across the United States. We used eleven land-cover categories to classify landscapes and tested their association with personality against broad physical and socioeconomic factors.

RESULTS

Urban areas were positively associated with openness to experience and negatively associated with conscientiousness. Coastal areas were positively associated with openness to experience and neuroticism but negatively associated with agreeableness and conscientiousness. Cultivated areas were negatively associated with openness. Landscapes at the periphery of human activity, such as shrubs, bare lands, or permanent snows, were not reliably associated with personality traits.

CONCLUSIONS

Bivariate correlations, multilevel, and random forest models uncovered robust associations between landscapes and personality traits. These findings align with ecological theory suggesting that an individual's environment contributes to their behaviors, thoughts, and feelings.

Ingroup favoritism on perceived risk of infectious diseases

Humans live in social groups; thus, infectious diseases may threaten human health and safety. Do individuals exhibit ingroup favoritism or ingroup devaluation when faced with varying risks of infectious diseases? We generated relatively realistic disease scenarios to examine this question. We reported the results from three experiments in which we tested individuals' perceived disease risk from ingroup and outgroup members under high- and low-risk conditions. Experiment 1 used a realistic influenza scenario, and Experiments 2 and 3 used a realistic scenario of exposure to coronavirus disease 2019 (COVID-19). All three experiments showed that perceived disease risk was significantly lower from ingroup members than from outgroup members and significantly lower in low-risk conditions than in high-risk conditions. Furthermore, the perceived disease risk was significantly lower from ingroup members than from outgroup members in high-risk conditions but did not significantly differ in low-risk conditions, as in Experiment 1's influenza scenario and Experiment 2's COVID-19 vaccination scenario. This suggests that ingroup favoritism is flexible. The results support ingroup favoritism and the functional flexibility principle in response to disease threats according to perceived disease risk.

Cultural Psychology: Beyond East and West

Research in cultural psychology over the last three decades has revealed the profound influence of culture on cognitive, emotional, and motivational processes shaping individuals into active agents. This article aims to show cultural psychology's promise in three key steps. First, we review four notable cultural dimensions believed to underlie cultural variations: independent versus interdependent self, individualism versus collectivism, tightness versus looseness of social norms, and relational mobility. Second, we examine how ecology and geography shape human activities and give rise to organized systems of cultural practices and meanings, called eco-cultural complexes. In turn, the eco-cultural complex of each zone is instrumental in shaping a wide range of psychological processes, revealing a psychological diversity that extends beyond the scope of the current East-West literature. Finally, we examine some of the non-Western cultural zones present today, including Arab, East Asian, Latin American, and South Asian zones, and discuss how they may have contributed, to varying degrees, to the formation of the contemporary Western cultural zone.

Influence of acculturation and cultural values on the self-reference effect

Cultural milieu can influence the way information is processed and what strategies are employed to deal with ever-changing environments. This study assessed whether acculturation and cultural values of East Asians can affect memory, with a specific focus on the self-reference effect in Chinese international students. Participants encoded and retrieved adjectives, with some trials relating the words to the self (i.e., the self-referencing task), another person, or a control condition; participants also completed questionnaires assessing cultural adaptation and self-construal. Results did not show a relationship between acculturation orientation and self-construal and the magnitude of the self-reference effect in memory, defined as better memory for adjectives encoded related to the self compared to those related to close others, in this sample of Chinese international students. Future research should explore effects of acculturation over time, incorporating more heterogeneous samples and sensitive neural measures.

Collectivist culture, environmental regulation and pollution emissions: evidence from China

Collectivist culture serves as a significant cultural foundation in China. It could, to some extent, shape public attitudes toward the environment and thus influence the implementation of related policies. To examine this hypothesis, this study constructs the collectivist culture intensity index for 25 Chinese provinces spanning from 2010 to 2020. Through a fixed-effect model, we explore how the collectivist culture intensity affects pollution emissions in China. The empirical results indicate the significance of collectivism in enhancing emission reduction through environmental regulations. This conclusion remains robust even when excluding the impact of endogeneity concerns by adopting the instrumental variable approach. Heterogeneity analysis shows that collectivism is more effective in enhancing market-based environmental regulations rather than those driven by policies. Further mechanism analysis confirms that green innovation is a crucial pathway through which collectivism influences pollution emissions. These findings here will offer guidance to policymakers when formulating environmental policies for contexts with different regional cultures.

Identifying culture as cause: Challenges and opportunities

Causal inference lies at the core of many scientific endeavours. Yet answering causal questions is challenging, especially when studying culture as a causal force. Against this backdrop, this paper reviews research designs and statistical tools that can be used - together with strong theory and knowledge about the context of study - to identify the causal impact of culture on outcomes of interest. We especially discuss how overlooked strategies in cultural evolutionary studies can allow one to approximate an ideal experiment wherein culture is randomly assigned to individuals or entire groups (instrumental variables, regression discontinuity design, and epidemiological approach). In doing so, we also review the potential outcome framework as a tool to engage in causal reasoning in the cultural evolutionary field.

Differences in eye movements for face recognition between Canadian and Chinese participants are not modulated by social orientation

Face recognition strategies do not generalize across individuals. Many studies have reported robust cultural differences between West Europeans/North Americans and East Asians in eye movement strategies during face recognition. The social orientation hypothesis posits that individualistic vs. collectivistic (IND/COL) value systems, respectively defining West European/North American and East Asian societies, would be at the root of many cultural differences in visual perception. Whether social orientation is also responsible for such cultural contrast in face recognition remains to be clarified. To this aim, we conducted two experiments with West European/North American and Chinese observers. In Experiment 1, we probed the existence of a link between IND/COL social values and eye movements during face recognition, by using an IND/COL priming paradigm. In Experiment 2, we dissected the latter relationship in greater depth, by using two IND/COL questionnaires, including subdimensions to those concepts. In both studies, cultural differences in fixation patterns were revealed between West European/North American and East Asian observers. Priming IND/COL values did not modulate eye movement visual sampling strategies, and only specific subdimensions of the IND/COL questionnaires were associated with distinct eye-movement patterns. Altogether, we show that the typical contrast between IND/COL cannot fully account for cultural differences in eye movement strategies for face recognition. Cultural differences in eye movements for faces might originate from mechanisms distinct from social orientation.

Development and validation of a scale assessing parental varied responses to Chinese adolescents' negative emotions

OBJECTIVES

Parental responses to children's negative emotions (PRCNE) constitute a critical construct in the study of emotion socialization in children and adolescents. The objective of this research was to develop and validate a concise scale for assessing how adolescents perceive PRCNE in a Chinese context, resulting in the creation of the parental varied responses to Chinese adolescents' negative emotions (PVRCANE) scale. The PVRCANE aims to evaluate seven forms of PRCNE, including the six types encompassed by the commonly used Coping with Children's Negative Emotions Scale-Adolescent Version (CCNES-AV), as well as an additional, culturally specific category frequently seen in Chinese families: didactic talk and teaching.

METHODS

In Study 1, a group of participants (N = 901, Mage  = 13.39 years, SD = 0.92) completed the initial PVRCANE and the CCNES-Adolescent Version. In Study 2: A separate group of participants (N = 320, Mage  = 13.54 years, SD = 0.57) filled in PVRCANE and scales evaluating parental socialization goals and adolescents' depressive symptoms.

RESULTS

In Study 1, factor analyses showed that a four-factor structure best fit the data, leading to the final version of the PVRCANE, which includes 35 items. PVRCANE scores exhibited good internal consistency (Omega > 0.79) and convergent validity, demonstrated by their close correlation with traditional CCNES scores. Study 2 confirmed the PVRCANE's measurement invariance for both male and female parents and demonstrated criterion validity by showing significant relationships between PVRCANE scores, parental socialization goals, and adolescents' symptoms of depression.

CONCLUSION

The PVRCANE is a brief, valid, and reliable scale for assessing PRCNE in Chinese adolescents. The study concludes with a discussion on future directions and how this research enhances the existing literature on emotion socialization, with a particular emphasis on the scale's potential application in other cultural settings.

Aging, crops and pesticide input: empirical evidence from rural China

BACKGROUND

Although scholars have elaborated on the effects of aging, there is no consensus on the relationship between the aging and farmers' pesticide input. Regional differences in agricultural crops in China, namely 'Southern Rice and Northern Wheat', have not been considered in any of the existing studies.

RESULTS

Based on the data of 443 wheat farmers and 324 rice farmers in China, this study found that aging significantly increased pesticide input. After sorting out the types of pesticides, it was found that the aging significantly increased the input of biological pesticides, but did not affect the input of chemical pesticides. After considering the planting pattern of 'Southern Rice and Northern Wheat', aging did not have a significant impact on the pesticide input of wheat farmers, but had a significant positive impact on the pesticide input of rice farmers. For wheat farmers in the north, social services have a significant inhibitory effect on the relationship between aging and pesticide input. For rice farmers, path dependence has a significant role in promoting the relationship between aging and pesticide input.

CONCLUSION

The planting pattern of 'Southern Rice and Northern Wheat' will indeed affect the relationship between aging and pesticide input, and social services and path dependence are the main reasons for this heterogeneity effect. Therefore, improving agricultural socialization services and reducing farmers' dependence on traditional production experience will be an important way to effectively reduce the impact of aging. © 2023 Society of Chemical Industry.

People in Tight Cultures and Tight Situations Wear Masks More: Evidence From Three Large-Scale Studies in China

Studies have found large differences in masks use during the pandemic. We found evidence that cultural tightness explains mask use differences and this association was more robust in tight situations like subways. In Study 1, we observed 23,551 people's actual mask use in public places around China. People wore masks more in tight situations; however, differences did not extend to outdoor streets and public parks, where norms are looser. We replicated this finding using a data from 15,985 people across China. Finally, in a preregistered study we observed mask use with the removal of COVID-19 restrictions, people still wore masks more in tight situations like subways than in loose situations of parks. These findings suggest that norm tightness has a lasting association with people's health-protective behaviors, especially in tight situations. It provides insight into how different cultures might respond with future pandemics and in what situations people adopt health-protective behaviors.

CEO cultural background and overinvestment decisions: The north-south divide in China

This study addresses an under-researched area in corporate behavior by examining the impact of a CEO's cultural background on corporate overinvestment decisions. We focus on the unique cultural dichotomy between northern and southern China as our context of study. Additionally, we scrutinize the interactions between a CEO's age and the type of company ownership in influencing overinvestment tendencies. Our aim is to enrich theoretical understanding of factors influencing corporate overinvestment, offering practical implications for businesses within and beyond China. By filling this gap in the literature, our study sheds light on the nuanced determinants of overinvestment decisions, aiding businesses in refining their investment strategies and governance mechanisms.
