Cultural variation: considerations and implications

Cultural challenges for adapting behavioral intervention frameworks: A critical examination from a cultural psychology perspective

We introduce the bias and equivalence framework to highlight how concepts, methods, and tools from cultural psychology can contribute to successful cultural adaptation and implementation of behavioral interventions. To situate our contribution, we provide a review of recent cultural adaptation research and existing frameworks. We identified 68 different frameworks that have been cited when reporting cultural adaptations and highlight three major adaptation dimensions that can be used to differentiate adaptations. Regarding effectiveness, we found an average effect size of zr = 0.24 (95%CI 0.20, 0.29) in 24 meta-analyses published since 2014, but also substantive differences across domains and unclear effects of the extent of cultural adaptations. To advance cultural adaptation efforts, we outline a framework that integrates key steps from previous cultural adaptation frameworks and highlight how cultural bias and equivalence considerations in conjunction with community engagement help a) in the diagnosis of behavioral or psychological problems, b) identification of possible interventions, c) the selection of specific mechanisms of behavior change, d) the specification and documentation of dose effects and thresholds for diagnosis, e) entry and exit points within intervention programs, and f) cost-benefit-sustainability discussions. We provide guiding questions that may help researchers when adapting interventions to novel cultural contexts.

Cognitive-Cultural Looping Mechanism of Urban Space Conceptualization

A crucial point for urban design is the acknowledgement that urban material structures are not only constituting a set of cognitive-cultural affordances that shapes people's behavior and experiential world, but likewise that the design process itself is an expression of cultural conceptualizations possibly evoked by ongoing cultural practices and perceptions, thus forming a dynamic loop. In this paper, we outline a framework for the study of material, cultural and social mechanisms interacting with human cognition, behavior and emotions. We attempt a conceptual model that integrates dynamic interactions between cognitive-cultural affordances and our conceptualization of the environment and provides a few illustrative case examples. The model proposes a set of dynamic relations between cognitive and cultural processes at shorter time scales modifying conceptualizations and environmental affordances on longer timescales, while these - in turn - come to guide and constrain processes at the shorter timescales. The model has important implications for our understanding of the role of environmental design, especially urban design, as bridging between aspects of human situated experience, behavior, social and cultural norms and material culture.

Rural-urban migration as a factor associated with physical and sexual intimate partner violence Peru 2015-2017: a secondary analysis of a national study

Background

Internal migration, a consequence of the demographic transition towards urbanization driven by globalization, represents a particular public health challenge. Change in residence from one sociocultural geographic context to another, with not only economic implications, but also changes in women’s long-established relationships of family interdependence, influences gender relations and can influence Intimate Partner Violence (IPV) against women. Different migratory trajectories may be related to IPV. The aim of this study was to identify the association between internal migration and physical and/or sexual violence against women in the last 12 months.

Methods

A secondary analytical cross-sectional analysis of the publicly accessible 2015–2017 Demographic and Family Health Survey (DHS) was performed. The outcome variable was reported physical and/or sexual violence inflicted by the partner (IPV) during the last 12 months. Exposure variable was internal migration, operationalized from three questions: current place of residence, principal place of residence before 12 years of age and number of years of residence in the current place. Migrants were classified as those who reported having lived for 5 years or more in the current location and were categorized as rural-rural migrants, urban-urban migrants, urban–rural migrants and rural–urban migrants, recent migrants and nonmigrants those who resided in the same place all their lives. To identify the association between internal migration and physical violence, a generalized linear model (GLM) of the family and the log Poisson link log option was used, and the results are presented as prevalence ratios (PRs). A crude model and a model adjusted for confounding variables were performed.

Results

Rural–urban migrant women had a 15.0% higher probability of experiencing IPV than nonmigrant women (PRa 1.15, 95% CI 1.03–1.29, p = 0.015), while the probability of experiencing IPV in the last 12 months for urban–rural, rural-rural,urban-urban migrantand recent migrant women was not significantly different from that of nonmigrant women.

Conclusion

Rural–urban migration among women of childbearing age is a factor associated with a higher probability of IPV in the last 12 months. The identification of women with this rural–urban migration pattern could help prioritize those that may experience a greater probability of physical and/or sexual violence in Peru, it must be studied if this pattern is the same in other countries.

Cultural Syndromes in a Changing World: A Longitudinal Investigation of Brazilian Jeitinho Social Problem-Solving Strategies

We report a longitudinal study of Jeitinho brasileiro (salient cultural characteristic of Brazil) during a period of significant political instability. Previous historical and anthropological sources have pointed to the importance of political instability for cultural changes in behaviors such as jeitinho. We are the first to examine possible individual-level dynamics over time, reporting a 3-year longitudinal study (N = 205) of two dimensions that differentiate keeping a socially pleasant social climate (simpatia) from trickery and breaking social norms. Using longitudinal network analysis, we found (a) reinforcing links between behavioral nodes within each of these two jeitinho clusters over time, (b) few between-cluster links, (c) within-person and between-person components were distinct, and (d) only the between-person structure resembled the overall factor structure. Overall, our data show that cultural behaviors are systematically changing during a political crisis, offering first insights how cultural systems may change via shifts in individual behavior.

Viewing Development Through the Lens of Culture: Integrating Developmental and Cultural Psychology to Better Understand Cognition and Behavior

Although many definitions of culture exist, studies in psychology typically conceptualize different cultures as different countries. In this article, we argue that cultural psychology also provides a useful lens through which to view developmental milestones. Like other forms of culture, different developmental milestones are demarcated by shared values and language as well as transmission of particular social norms. Viewing development through the lens of cultural psychology sheds light on questions of particular interest to cultural psychologists, such as those concerning the emergence of new cultures and the role of culture in shaping psychological processes. This novel framework also clarifies topics of particular interest to developmental psychology, such as conflict between individuals at different milestones (e.g., arguments between older and younger siblings) and age-related changes in cognition and behavior.

Why do Westerners self‐enhance more than East Asians?

Much research finds that Westerners self‐enhance more than East Asians, with the exception of studies using the implicit associations test for self‐esteem (IATSE). We contrasted Japanese and Canadians on a new measure of self‐enhancement under low‐ and high‐attentional load to assess whether cultural differences vary across controlled and automatic processes. Participants also completed measures of relational mobility and the IATSE. Results indicated that Japanese and Asian‐Canadians were more self‐critical than Euro‐Canadians, both under high‐ and low‐attentional load. This cultural difference was partially mediated by relational mobility. The IATSE showed no cultural differences, but this measure did not positively correlate with any of the other measures in the study, suggesting that it is not a valid measure of ‘true’ self‐feelings.

When is search for meaning in life beneficial for well-being? A cross-national study

Previous research has found cross-national variations in the association between search for meaning in life (SMIL) and well-being (i.e. SMIL-WB link). This study extended and tested a "self-improvement hypothesis" that accounts for such cross-national variations based on an international database-the sixth wave of World Values Survey. SMIL represents a self-improvement effort which is more demanded in contexts with stronger external constraints. Thus, we expected a stronger positive SMIL-WB link in such contexts. A series of multilevel analyses was used to verify this hypothesis. The results showed that the SMIL-WB link varied across different societies, with well-being indexed by happiness, life satisfaction and subjective health. Moreover, external constraints from cultural, social-institutional, economic and ecological contexts (collectivism, peace threats, economic scarcity and environmental threats) moderated the SMIL-WB links. We thus call for advancing SMIL theory by considering person-context interaction.

The Dilemmas of Scientific Research Cooperation and Their Resolution From the Perspective of Evolutionary Psychology

Scientific research cooperation has become a mainstream trend of social development. It can promote resource sharing, help group members complement each other’s advantages, and improve scientific research efficiency. With the deepening of scientific research cooperation, there have also been problems such as the uneven strength of partners, gender discrimination, and group exclusionary behavior. People often explore the causes of these problems in terms of the process of scientific research cooperation, but doing so fails to solve the substantive problems effectively. We thus seek to trace the psychology of people participating in scientific research cooperation from the perspective of evolutionary psychology so as to analyze the root causes of scientific research cooperation problems. This paper first discusses the importance of scientific research cooperation, then enumerates common problems in scientific research cooperation, analyzes them from the perspective of evolutionary psychology, and proposes solutions to these problems from the perspective of regulating people’s psychology. This article illustrates how the many perspectives and theories of evolutionary psychology can solve problems in other disciplines and fields, and indeed that all human social activities can be explained by evolutionary psychology, which opens up a broader field of research for evolutionary psychology.

Population Diversity and Ancestral Diversity As Distinct Contributors to Outgroup Prejudice

Previous research has shown conflicting findings on how population diversity influences outgroup prejudice. In some cases, prejudice is greater when minority groups make up a larger portion of the population, whereas in other cases, prejudice is lower as diversity increases. This article examined how the diversity of a culture's ancestry-or its historical heterogeneity-would be related to outgroup attitudes. Historically heterogeneous populations descend from ancestors who have migrated from many parts of the world over the past 500 years and, as a result, have a longer legacy of contact with diverse groups of people. The results of two cross-cultural studies found that greater heterogeneity predicted lower levels of outgroup prejudice, and some evidence that diversity in the current population was related to increased prejudice. The findings suggest that intergroup attitudes have deeply entrenched roots that cannot be fully understood by looking at current indicators.

Emerging evidence of cultural differences linked to rice versus wheat agriculture

Roughly four billion people live in cultures with a legacy of rice farm. Recent studies find that rice cultures are more interdependent than herding cultures and wheat-farming cultures. In China, people from rice-farming areas think more holistically and show less implicit individualism than people from wheat-farming areas. These differences are mirrored in micro-level comparisons of neighboring counties differ in rice versus wheat. Research has also found evidence of cultural differences based on rice farming within Japan and around the world. However, we know little about the mechanism of how rice culture is transmitted in the modern world. More research is needed on the mechanisms, as well as other subsistence styles, such as corn farming and cash crops like sugar.

The Evolution of Prosocial and Antisocial Competitive Behavior and the Emergence of Prosocial and Antisocial Leadership Styles

Evolutionary analysis focuses on how genes build organisms with different strategies for engaging and solving life's challenges of survival and reproduction. One of those challenges is competing with conspecifics for limited resources including reproductive opportunities. This article suggests that there is now good evidence for considering two dimensions of social competition. The first, has been labeled as antisocial strategies, to the extent that they tend to be self-focused, threat sensitive and aggressive, and use tactics of bulling, threatening, and intimidating subordinates, or even injuring/killing competitors. Such strategies can inhibit care and affiliative social interactions and motivation. The social signals emitted stimulate threat processing in recipients and can create stressed and highly stratified groups with a range of detrimental psychological and physiological effects. Second, in contrast, prosocial strategies seek to create relaxed and secure social interactions that enable sharing, cooperative, mutually supportive and beneficial relationships. The friendly and low/no threat social signals emitted in friendly cooperative and affiliative relationships stimulate physiological systems (e.g., oxytocin, the vagus nerve of the parasympathetic system) that downregulates threat processing, enhances the immune system, and facilitates frontal cortical processes and general wellbeing. This article reviews the literature pertaining to the evidence for these two dimensions of social engagement.

Heterogeneity of long-history migration predicts smiling, laughter and positive emotion across the globe and within the United States

Recent findings demonstrate that heterogeneity of long-history migration predicts present-day emotion behaviors and norms. Residents of countries characterized by high ancestral diversity display emotion expressions that are easier to decode by observers, endorse norms of higher emotion expressivity, and smile more in response to certain stimuli than residents of countries that lack ancestral diversity. We build on the extant findings and investigate historical heterogeneity as a predictor of daily smiling, laughter, and positive emotion across the world’s countries and the states of the United States. Study 1 finds that historical heterogeneity is positively associated with self-reports of smiling, laughter, and positive emotions in the Gallup World Poll when controlling for GDP and present-day population diversity. Study 2 extends the findings to effects of long-history migration within the United States. We estimated the average percentage of foreign-born citizens in each state between 1850 and 2010 based on US Census information as an indicator of historical heterogeneity. Consistent with the world findings of Study 1, historical heterogeneity predicted smiling, laughter, and positive, but not negative, emotion. The relationships remained significant when controlling for per capita income and present-day population diversity of each state. Together, the findings further demonstrate the important role of long-history migration in shaping emotion cultures of countries and states, which persist beyond the original socio-ecological conditions, and open promising avenues for cross-cultural research.

The Cultural Boundaries of Perspective-Taking: When and Why Perspective-Taking Reduces Stereotyping

Research conducted in Western cultures indicates that perspective-taking is an effective social strategy for reducing stereotyping. The current article explores whether and why the effects of perspective-taking on stereotyping differ across cultures. Studies 1 and 2 established that perspective-taking reduces stereotyping in Western but not in East Asian cultures. Using a socioecological framework, Studies 2 and 3 found that relational mobility, that is, the extent to which individuals' social environments provide them opportunities to choose new relationships and terminate old ones, explained our effect: Perspective-taking was negatively associated with stereotyping in relationally mobile (Western) but not in relationally stable (East Asian) environments. Finally, Study 4 examined the proximal psychological mechanism underlying the socioecological effect: Individuals in relationally mobile environments are more motivated to develop new relationships than those in relationally stable environments. Subsequently, when this motivation is high, perspective-taking increases self-target group overlap, which then decreases stereotyping.

How Does Culture Matter in the Face of Globalization?

Globalization has made exposure to multiple cultures not only possible, but often necessary and unavoidable. This article focuses on how people react and adapt to increasing globalization and multiculturalism. We posit that reactions to multiculturalism and intercultural contact are not universal and are themselves shaped by cultural experiences. That is, culture provides a frame of reference for reconciling and negotiating the inflow of foreign cultures and peoples. Although exposure to foreign cultures can widen one’s worldview, thereby enhancing creativity and reducing prejudice, intercultural contact can also bring about negative exclusionary responses such as aversion, disgust, and defensiveness. We explore how culture and individual differences, such as a belief in racial essentialism, critically shape reactions to intercultural contact. Our discussion sheds light on recent geopolitical and societal shifts that reflect an increased backlash against rising globalization and cultural diversity.

I Want to but I Won't: Pluralistic Ignorance Inhibits Intentions to Take Paternity Leave in Japan

The number of male employees who take paternity leave in Japan has been low in past decades. However, the majority of male employees actually wish to take paternity leave if they were to have a child. Previous studies have demonstrated that the organizational climate in workplaces is the major determinant of male employees' use of family-friendly policies, because males are often stigmatized and fear receiving negative evaluation from others. While such normative pressure might be derived from prevailing social practices relevant to people's expectation of social roles (e.g., “Men make houses, women make homes”), these social practices are often perpetuated even after the majority of group members have ceased to support them. The perpetuation of this unpopular norm could be caused by the social psychological phenomenon of pluralistic ignorance. While researches have explored people's beliefs about gender roles from various perspectives, profound understanding of these beliefs regarding gender role norms, and the accuracy of others' beliefs remains to be attained. The current research examined the association between pluralistic ignorance and the perpetually low rates of taking paternity leave in Japan. Specifically, Study 1 (n = 299) examined Japanese male employees' (ages ranging from the 20 s to the 40 s) attitudes toward paternity leave and to estimate attitudes of other men of the same age, as well as behavioral intentions (i.e., desire and willingness) to take paternity leave if they had a child in the future. The results demonstrated that male employees overestimated other men's negative attitudes toward paternity leave. Moreover, those who had positive attitudes toward taking leave and attributed negative attitudes to others were less willing to take paternity leave than were those who had positive attitudes and believed others shared those attitudes, although there was no significant difference between their desires to take paternity leave. Study 2 (n = 425) replicated these results and further indicated that they could not be explained by the participants' needs to be socially desirable. Together, our findings suggest that pluralistic ignorance occurs in the context of taking paternity leave in Japanese men, and this leads to the low use of available paternity leave.

Feelings and contexts: socioecological influences on the nonverbal expression of emotion

Despite their relative universality, nonverbal displays of emotion are often sources of cross-cultural misunderstandings. The present article considers the relevance of historical and present socio-ecological contexts, such as heterogeneity of long-history migration, pathogen prevalence, and residential mobility for cross-cultural variation in emotional expression. We review recent evidence linking these constructs to psychological processes and discuss how the findings are relevant to the nonverbal communication of emotion. We hold that socioecological variables, because of their specificity and tractability, provide a promising framework for explaining why different cultures developed varying modes of emotional expression.

Honor as Cultural Mindset: Activated Honor Mindset Affects Subsequent Judgment and Attention in Mindset-Congruent Ways

Honor values articulate gender roles, the importance of reputation in maintaining one’s place in society, and maintaining respect for the groups one belongs to. In that sense honor provides a template for organizing social interactions and hence may be functional even among people and societies that do not report valuing and endorsing honor. We test the prediction that honor influences judgment and attention when activated in two experiments (N = 538). Using a culture-as-situated cognition perspective, we predicted that activating one aspect of honor would activate other aspects, even among individuals who do not much endorse honor values. We tested these predictions among European Americans, a group that is not typically associated with honor values. In each study, participants were randomly assigned to experimental or control groups, which differed in one way: the experimental group read statements about honor values as a first step and the control group did not. Participants then judged stick-figure pairs (judging which is male; Study 1, n = 130) or made lexical decisions (judging whether a letter-string formed a correctly spelled word; Study 2, n = 408). In Study 1, experimental group participants were more likely to choose the visually agentic figure as male. In Study 2, experimental group participants were more accurate at noticing that the letter-string formed a word if the word was an honor-relevant word (e.g., noble), but they did not differ from the control group if the word was irrelevant to honor (e.g., happy). Participants in both studies were just above the neutral point in their endorsement of honor values. Individual differences in honor values endorsement did not moderate the effects of activating an honor mindset. Though honor is often described as if it is located in space, we did not find clear effects of where our letter strings were located on the computer screen. Our findings suggest a new way to consider how honor functions, even in societies in which honor is not a highly endorsed value.

Culture and Aggression—From Context to Coercion

This article is an attempt to study the neglected linkages between culture and aggression. It does so by conceptualizing culture as a set of affordances and constraints that channel the expression of coercive means of social control by self and others. All cultural systems represent solutions to the problems associated with distributing desired material and social resources among its group members while maintaining social order and harmony. Norms are developed surrounding the exercise of mutual influence in the process of resource allocation, favoring some and marginalizing others. Violations of these norms by resource competitors are conceptualized as “aggressive” behaviors and stimulate a process of justified counterattack, escalating the violence. The current data from both societal-level and individual-level studies are examined and integrated in light of this organizing framework, and future studies are proposed to explore the interface between culture and aggression more productively.

Culture Three Ways: Culture and Subcultures Within Countries

Culture can be thought of as a set of everyday practices and a core theme-individualism, collectivism, or honor-as well as the capacity to understand each of these themes. In one's own culture, it is easy to fail to see that a cultural lens exists and instead to think that there is no lens at all, only reality. Hence, studying culture requires stepping out of it. There are two main methods to do so: The first involves using between-group comparisons to highlight differences and the second involves using experimental methods to test the consequences of disruption to implicit cultural frames. These methods highlight three ways that culture organizes experience: (a) It shields reflexive processing by making everyday life feel predictable, (b) it scaffolds which cognitive procedure (connect, separate, or order) will be the default in ambiguous situations, and (c) it facilitates situation-specific accessibility of alternate cognitive procedures. Modern societal social-demographic trends reduce predictability and increase collectivism and honor-based go-to cognitive procedures.

Individualism, Collectivism, and Authoritarianism in Seven Societies

Building on Hofstede's finding that individualism and social hierarchy are incompatible at the societal level, the authors examined the relationship between individualism-collectivism and orientations toward authority at the individual level. In Study 1, authoritarianism was related to three measures of collectivism but unrelated to three measures of individualism in a U.S. sample ( N = 382). Study 2 used Triandis's horizontal-vertical individualism-collectivism framework in samples from Bulgaria, Japan, New Zealand, Germany, Poland, Canada, and the United States (total N = 1,018). Both at the individual level and the societal level of analysis, authoritarianism was correlated with vertical individualism and vertical collectivism but unrelated to horizontal collectivism. Horizontal individualism was unrelated to authoritarianism except in post-Communist societies whose recent history presumably made salient the incompatibility between state authority and self-determination.

Representation and Incorporation of Close Others’ Responses

We propose a new model of social influence, which can occur spontaneously and in the absence of typically assumed motives. We assume that perceivers routinely construct representations of other people’s experiences and responses (beliefs, attitudes, emotions, and behaviors), when observing others’ responses or simulating the responses of unobserved others. Like representations made accessible by priming, these representations may then influence the process that generates perceivers’ own responses, without intention or awareness, especially when there is a strong social connection to the other. We describe evidence for the basic properties and important moderators of this process, which distinguish it from other mechanisms such as informational, normative, or social identity influence. The model offers new perspectives on the role of others’ values in producing cultural differences, the persistence and power of stereotypes, the adaptive reasons for being influenced by others’ responses, and the impact of others’ views about the self.

Friendships of Indonesian and United States youth

Issues in the study of friendship across cultures were explored by reviewing a set of studies focusing on the friendships of Indonesian and United States youth. Four topics are considered: similarity of friendships across cultures, dimensions of friendships that vary across cultures, the utility of the individualism/collectivism dimension for explaining cultural differences in friendship, and methodological issues in the study of culture and friendship. Two studies are presented that address some of these issues. Although friendships of US and Indonesian youth are similar across many dimensions, the friendships of Indonesian youth appear somewhat less close, more centred on instrumental aid, less focused on enhancement of worth, and more extensive and less exclusive than those of US youth. These patterns are opposite to those that have emerged in the comparison of those in the US and other collectivist cultures, suggesting the need to modify models of collectivism and friendship. Finally, the authors advocate the use of multimethod and multiagent assessments, addressing issues of social class in cross-cultural comparison, and using a combination of quantitative and qualitative approaches to study culture and friendship.

Implications of an Emerging Integration of Universal and Culturally Specific Psychologies

Psychological researchers increasingly recognize that human behavior reflects a complex interplay of universal human capacities, cultural responses to unique histories and circumstances, and individual differences. Many psychological processes appear to reflect culturally specific instantiations of universal capacities. Current integrative research focuses on further clarifying definitions of universality and on refining methods for identifying universal and cultural components of psychological processes. In this article, we consider implications of this emerging integration. To illustrate possible implications for psychology, we apply it to the study of psychopathology. We report on formal models that explain why some cultures embrace dysfunction among members. We then use the integrative framework to describe methods for determining whether putative disorders bring universal or contextual life dysfunction and to clarify etiological models of three disorders. Models of psychopathology can be more informed and precise if they include careful consideration of both universal and cultural influences on behavior.

[VOLTAGE-GATED CALCIUM CHANNELS: CLASSIFICATION AND PHARMACOLOGICAL PROPERTIES (PART I).]

Calcium influx though voltage-gated calcium channels mediate a huge amount of physiological events and cellular responses. Numerous scientific reports indicate that calcium channels are involved in synaptic transmission, neurotransmitter release, regulation of gene expression, cellular membrane voltage oscillations, pacemaker activity, secretion of specific substances from nerve and secretory cells, morphological differentiation, activation of calcium-dependent enzymes, etc. This review represents the modern classification, molecular structure, physiological and pharmacological properties of voltage-gated calcium channels expressed in mammalian cells.

From one mind to many: the emerging science of cultural norms

Cultural norms permeate human existence. They shape our view of reality and the evolution of culture. In this review, we discuss the benefits of a cultural science that studies norms as well as values, and review research on (a) whether cultural norms are distinctly human, (b) when people will follow cultural norms, and (c) what factors shape the content and strength of cultural norms. We argue that studying cultural norms represents a critical cross-disciplinary, multi-level approach that is ideal for both understanding culture and tapping its potential for positive change.

Culture and Psychology in the 21st Century

At the end of the 20th century, a survey of the metatheoretical landscape of culture and psychology noted an emerging consensus—physicalist ontology, gene–culture co-evolutionary phylogeny, gene–culture interactionist ontogeny, and a mutual constitutionist view of culture and mind. Revisiting the terrain now, the then emerging consensus seems well established, but new challenges appear on the horizon, prompting us to expand our metatheoretical scope. Extending beyond phylogeny, we need to consider a geological timescale, and further naturalizing the culture concept, we need to consider culture and human activity within the planetary system. According to some, we have left the Holocene, and entered into the Anthropocene, a geological epoch in which human activities have such a disproportionate impact that it deserves to be prefaced by humanity. Psychology with interests in culture can play a critical role in human efforts to investigate the psychological processes involved in the cultural change and to reconceptualize humans’ place in nature.

Toward a Psychological Science for a Cultural Species

Humans are a cultural species, and the study of human psychology benefits from attention to cultural influences. Cultural psychology's contributions to psychological science can largely be divided according to the two different stages of scientific inquiry. Stage 1 research seeks cultural differences and establishes the boundaries of psychological phenomena. Stage 2 research seeks underlying mechanisms of those cultural differences. The literatures regarding these two distinct stages are reviewed, and various methods for conducting Stage 2 research are discussed. The implications of culture-blind and multicultural psychologies for society and intergroup relations are also discussed.

Heterogeneity of long-history migration explains cultural differences in reports of emotional expressivity and the functions of smiles

A small number of facial expressions may be universal in that they are produced by the same basic affective states and recognized as such throughout the world. However, other aspects of emotionally expressive behavior vary widely across culture. Just why do they vary? We propose that some cultural differences in expressive behavior are determined by historical heterogeneity, or the extent to which a country's present-day population descended from migration from numerous vs. few source countries over a period of 500 y. Our reanalysis of data on cultural rules for displaying emotion from 32 countries [n = 5,340; Matsumoto D, Yoo S, Fontaine J (2008) J Cross Cult Psychol 39(1):55-74] reveals that historical heterogeneity explains substantial, unique variance in the degree to which individuals believe that emotions should be openly expressed. We also report an original study of the underlying states that people believe are signified by a smile. Cluster analysis applied to data from nine countries (n = 726), including Canada, France, Germany, India, Indonesia, Israel, Japan, New Zealand, and the United States, reveals that countries group into "cultures of smiling" determined by historical heterogeneity. Factor analysis shows that smiles sort into three social-functional subtypes: pleasure, affiliative, and dominance. The relative importance of these smile subtypes varies as a function of historical heterogeneity. These findings thus highlight the power of social-historical factors to explain cross-cultural variation in emotional expression and smile behavior.

What Is Implicit Self-Esteem, and Does it Vary Across Cultures?

Implicit self-esteem (ISE), which is often defined as automatic self-evaluations, fuses research on unconscious processes with that on self-esteem. As ISE is viewed as immune to explicit control, it affords the testing of theoretical questions such as whether cultures vary in self-enhancement motivations. We provide a critical review and integration of the work on (a) the operationalization of ISE and (b) possible cultural variation in self-enhancement motivations. Although ISE measures do not often vary across cultures, recent meta-analyses and empirical studies question the validity of the most common way of defining ISE. We revive an alternative conceptualization that defines ISE in terms of how positively people evaluate objects that reflect upon themselves. This conceptualization suggests that ISE research should target alternative phenomena (e.g., minimal group effect, similarity-attraction effect, endowment effect) and it allows for a host of previous cross-cultural findings to bear on the question of cultural variability in ISE.

The Acculturation of Relational Mobility

In this article, we extended the socioecological approach in cross-cultural psychology to the acculturation context. We focused on relational mobility among Asian Canadians and how it is related to their acculturation experience. Previous research shows that relational mobility, which is a feature of one’s social environment, is generally higher in North America than East Asia. In Study 1, we found that migration does not completely bridge the cross-national gap in relational mobility. Compared with European Canadians, Asian Canadians continued to perceive lower relational mobility around them. Study 2 explored the relations between relational mobility and Asian Canadians’ acculturation experiences. Relational mobility was correlated specifically with sociocultural adaptation, but not contact, acculturation orientations, psychological adaptation, or experience of discrimination. It was also uniquely associated with normative belief about relational mobility. Finally, we largely replicated the effects of relational mobility on self-esteem (Study 1) and close friendships (Study 2) in the acculturation context, with the latter effects further mediated by normative belief about relational mobility. Implications of our findings for relational mobility and acculturation research are discussed.

Group-level traits emerge

Most commentators supported the thesis of the target article, though there were also those who were less fully persuaded. I will begin with a response to the most critical commentaries. First, I will justify an evolutionary perspective that includes group organization and nongenetic inheritance. Next, I will discuss the concept of emergence. Following that, I will transition to an exploration of ideas and concerns brought up by some of the more supportive commentators. This will include a discussion of different types of groups; the psychology of group-level traits; the uses and limitations of an institutional perspective; the link between transmission, adaptation, and selection; current and future methodologies; and the variety of fields that may benefit from a group-level traits perspective.

The Implicit Legacy of American Protestantism

The heritage of a nation founded by devout Puritan Protestants has had wide-ranging effects on U.S. culture and, as experimental evidence suggests, continues to exert an implicit influence on the feelings, judgments, and behaviors of contemporary Americans. The United States is distinguished by a faith in individual merit and traditional values uncommon among economically developed democracies, both of which have been traced, in part, to the moral ideals of the founding Protestant communities. Calvinist Protestantism has further profoundly shaped American workways, including the moralization of work and the manifestation of professional norms that prescribe impersonal and unemotional workplace interactions. The implicit influence of traditional Protestant beliefs extends not only to devout American Protestants, but even to non-Protestant and less-religious Americans.

Collectivism–Individualism, Family Ties, and Philopatry

As predicted by the parasite-stress theory of values, variation in parasite stress correlated with collectivism–individualism across nations, USA states, and indigenous societies. In regions with high adversity of infectious diseases, human cultures are characterized by high collectivism, whereas in regions of low parasite stress cultures are highly individualistic. The prediction from the parasite-stress theory of values that infectious disease transmissible among humans (nonzoonotics) will be more important in predicting collectivism–individualism than those that humans can contract only from nonhuman animals (zoonotics) was supported. Evidence in human movement patterns for nations, states of the USA, and indigenous societies supports the hypothesis that the absence of dispersal (high philopatry) is a defense against contact with novel parasites in out-groups and their habitats. We show that human cultures with high degrees of collectivism have high degrees of cooperative breeding, and propose that the parasite-stress theory of sociality offers a general theory of family structure across humans as well as nonhuman animal taxa. We propose that a major context for the evolution of human reciprocity was in gaining benefits from out-group interactions during periods of relatively low disease threat. The parasite-stress theory of values offers a novel perspective to explain the evolution of reciprocity and human unique cognitive abilities. The parasite-stress theory suggests useful new research directions for the study of the demographic transition, patriotism, xenophobia, ethnocentrism, and moral foundations theory. We include discussion of ecological correlations and the ecological fallacy. The fact that all scientific findings are correlational is explained.

Gene-Environment Interactions Are Associated With Endorsement of Social Hierarchy Values and Beliefs Across Cultures

The study tests gene-environment interactions for explaining cross-national differences in social hierarchy values and beliefs. Greater threats are predicted to be associated with stronger endorsement and support of social hierarchies in the presence of population genetic deficiencies in processing threat-related information. Predictions are tested with data from 28 societies, focusing on hierarchical dominance values in teachers and student samples (28 societies) and support for central authority in representative samples (21 societies). The interaction between greater population frequency of short alleles of the 5-HTT serotonin transporter gene and presence of threats was significant in six out of the eight regressions. I discuss the findings in the larger context of interdependencies between biological and cultural processes and the importance of broadening our tool kit for studying cultural differences.

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 of evidence suggesting its limitations. To examine these issues, cross-temporal analyses of individualism–collectivism in the United States and Japan were conducted. Diverging patterns of cultural changes were found across indices: In both countries, some of the obtained indices showed rising individualism over the past several decades, supporting the modernization theory. However, other indices showed patterns that are best understood within the frameworks of a shifting focus of social relationships and a persisting cultural heritage. A comprehensive theory of cultural change requires considerations of these factors in addition to the modernization effect.
