I study how human behavior emerges from the interplay between evolutionary pressures, historical contexts, and cultural meaning systems. Taking a complex systems approach, my research uses network psychometrics and computational methods to understand how values, personality, and contemplative practices function across diverse populations. This work has spanned collaborations in over 40 countries, revealing how psychological phenomena that appear universal often mask meaningful cultural variation, and how traditional measurement approaches can obscure this complexity.

Contemplative Practices Across Cultures

How do practices aimed at cultivating awareness and equanimity translate across cultural boundaries? My work spans the full spectrum of contemplative traditions, from Buddhist-derived mindfulness to ancient Stoic philosophy, examining how these practices function differently across cultural contexts and what they share in common as approaches to human flourishing.

Mindfulness Stoicism Cross-cultural measurement Contemplative science

Historical Psychology

Can we trace psychological concepts through history? Using computational text analysis and NLP, I extract personality and value structures from historical narratives, from the Epic of Gilgamesh to autobiographical texts, to understand how psychological constructs have evolved across millennia.

Human Values

Values sit at the intersection of evolutionary heritage and cultural learning, shaping how individuals navigate their social worlds. My research examines how values relate to well-being, political behavior, and life choices, using network approaches to reveal the dynamic interplay between what people care about and how they act. This includes directing a European Joint Research Council initiative on values in political rhetoric.

Cross-Cultural Methods

How do we know our measures mean the same thing across cultures? I develop network psychometric approaches and measurement invariance frameworks that reveal when traditional methods obscure meaningful cultural variation, and offer better alternatives.

Ritual and Social Behavior

Why do humans perform rituals? I study the psychological and social functions of ritual practices, from Diwali celebrations in India to everyday routines, examining how repetitive behaviors reduce anxiety, build social bonds, and create meaning.

Well-Being and Mental Health

What predicts flourishing across different contexts? I use network approaches to understand mental health in understudied populations, from veteran families to first responders, identifying distinct symptom patterns and intervention targets.

The Development and Validation of the Stoic Attitudes and Behaviours Scale

LeBon, T., Brown, G., DiGiuseppe, R., ... & Lopez, G. Cognitive Therapy and Research

Abstract

The Stoic Attitudes and Behaviours Scale (SABS) was developed to measure Stoicism as a life philosophy. In contrast, previous scales purporting to assess Stoicism have typically relied on a colloquial understanding of ‘stoic’—a concept distinct from philosophical Stoicism and often linked to poorer health outcomes.

The association between dual sensory impairment and dementia: a meta-analysis and systematic review of the literature

Zumbrunn, N. M., Beckett, K., Karl, J. A., ... & McGovern, D. P. Age and Ageing

Abstract

Recent evidence suggests an association between dual sensory impairment (DSI)—that is, both visual and hearing impairments—and dementia. The aim of this systematic review was to synthesise the literature evaluating the dementia risk of adults \>18 years with DSI compared to those without sensory impairment and/or those with a single sensory impairment (SSI).PubMed, Web of Science and PsycINFO were systematically searched in February 2024 and August 2024 for studies that considered the association between DSI and dementia, and compared individuals with DSI to those with either no sensory impairment or a SSI. A meta-analysis was conducted on studies reporting hazard ratios. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and was registered on the Prospective Register of Systematic Reviews (PROSPERO).A total of 22 papers were included in the narrative review, and 13 were included in the meta-analysis. Overall, findings from the narrative synthesis highlighted a consistent link between dementia prevalence and incidence with DSI. The meta-analysis revealed that individuals with DSI are at an

Abstract

Values have become central to the study of social and psychological processes across cultures and across time. To date, there has been no conclusive analysis of the cross-cultural and cross-temporal comparability of values in Europe. We conduct invariance tests of the Portrait Values Questionnaire collected as part of the European Social Survey (ESS, k = 261 samples, N = 374,565) from 2002 to 2024. Using confirmatory factor analysis, we found that the theoretical value model fits the overall data. Ignoring temporal information, covariances and mean value patterns can be compared across countries. Testing separate country samples collected in specific rounds, we found evidence that sample-specific results may not be comparable. Considering cross-temporal invariance, only 17 out of 35 countries with multiple participation in the ESS showed metric invariance. We observed patterns of deteriorating model fit and changes in the basic value structure over time.

Investigating the analytical robustness of the social and behavioural sciences

Aczel, B., Szaszi, B., Clelland, H. T., ... & Nosek, B. A.

Abstract

The same dataset can be analysed in different justifiable ways to answer the same research question, potentially challenging the robustness of empirical science1–3. In this crowd initiative, we investigated the degree to which research findings in the social and behavioural sciences are contingent on analysts’ choices. We examined a stratified random sample of 100 studies published between 2009 and 2018, where for one claim per study, at least five re-analysts independently re-analysed the original data. The statistical appropriateness of the re-analyses was assessed in peer evaluations, and the robustness indicators were inspected along a range of research characteristics and study designs. We found that 34\% of the independent re-analyses yielded the same result (within a tolerance region of +/- 0.05 Cohen’s d) as the original report; with a four times broader tolerance region, this indicator rose to 57\%. Regarding the conclusions drawn, 74\% of analyses were reported to arrive at the same conclusion as in the original investigation; 24\% to no effects/inconclusive result, and 2\% to the opposite effect as in the original investigation. This exploratory study suggests that the common single-path analyses in social and behavioural research should not simply be assumed to be robust to alternative analyses4. Therefore, we recommend the development and use of practices to explore and communicate this neglected source of uncertainty.

Measuring the semantic priming effect across many languages

Buchanan, E. M., Cuccolo, K., Heyman, T., ... & Lewis, S. C. Nature Human Behaviour

Abstract

Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. Although previous studies provide insight into the cognitive underpinnings of semantic representations, they have suffered from small sample sizes and a lack of linguistic and cultural diversity. In this Registered Report, we measured the size and the variability of the semantic priming effect across 19 languages (n = 25,163 participants analysed) by creating the largest available database of semantic priming values using an adaptive sampling procedure. We found evidence for semantic priming in terms of differences in response latencies between related word-pair conditions and unrelated word-pair conditions. Model comparisons showed that the inclusion of a random intercept for language improved model fit, providing support for variability in semantic priming across languages. This study highlights the robustness and variability of semantic priming across languages and provides a rich, linguistically diverse dataset for further analysis. The Stage 1 protocol for this Registered Report was accepted in principle on 15 July 2022. The protocol, as accepted by the journal, can be found at https://osf.io/u5bp6(registration) or https://osf.io/q4fjy(preprint version 6, 31 May 2022).

Veteran and first responder family members show distinct mental health networks centered on negative emotions

Karl, J. A., Ponder, W. N., Carbajal, J., & Medvedev, O. N. Communications Psychology

Abstract

The interplay of mental health symptoms among family members of veterans and first responders remains poorly understood despite their vital support role. Network analysis and community detection were performed on mental health assessment data from 317 treatment-seeking family members of trauma-exposed veterans and first responders, who completed clinical distress measures including posttraumatic stress disorder, depression, and anxiety. Network analysis revealed six distinct symptom communities: depression, generalized anxiety disorder, intrusion and avoidance, anxious arousal, externalizing behaviors, and negative alterations. Strong negative feelings (fear, horror, anger) and uncontrollable worry emerged as the most influential nodes in the network. Remarkably, 55.5\% of participants screened positive for probable posttraumatic stress disorder, while 38.5\% reported moderately severe to severe depression, and 36.6\% experienced severe generalized anxiety disorder. The network demonstrated high stability across bootstrap analyses, with a correlation stability coefficient exceeding 0.59. Overall, this study revealed network of co-occurring mental health symptoms in family members of veterans and first responders. The identification of six distinct symptom communities suggests that traditional diagnostic boundaries may not fully capture the complexity of psychological distress in this population. These findings highlight the need for targeted interventions addressing both fear-based trauma symptoms and mood dysregulation in this understudied group.

Abstract

The continued prevalence of sexism and gender inequalities across the world is a priority for research. We meta-analyzed all research since the inception of ambivalent sexism theory (1996–2023) that measured hostile sexism (i.e., derogatory attitudes) or benevolent sexism (i.e., patronizing attitudes) toward women. Using 1,097 samples from 81 countries, we considered evidence for principles of ambivalent sexism theory, including the extent to which endorsements of hostile sexism and benevolent sexism (a) differed across years, (b) were associated with one another, and (c) were associated with countries’ gender inequalities. Multilevel meta-analytic models indicated that endorsement of sexism generally followed trajectories of small declines over years, provided robust evidence that sexism is “ambivalent” because hostile sexism was consistently associated with greater benevolent sexism, and suggested that people’s greater endorsement of hostile sexism in a country predicted greater gender inequality in that country, although this association was attenuated in later samples. Implications of these tests informed theoretical gaps in need of research: investigating why the declining trajectories of sexism were stronger in some countries relative to others, identifying the most appropriate markers of gender inequality, and specifying the time lags between experienced inequalities and endorsement of sexism. Our multilevel meta-analysis provided initial information about the cross-country patterns of ambivalent sexism and established a need for longitudinal cultural research to identify the origins of ambivalent sexism and its consequences for gender inequalities across the world.

Commonly observed sex differences in direct aggression are absent or reversed in sibling contexts

Varnum, M. E. W., Kirsch, A. P., Beal, D. J., ... & Kenrick, D. T. PNAS Nexus

Abstract

Decades of research support the generalization that human males tend to be more aggressive than females. However, most of that research has examined aggression between unrelated individuals. Data drawn from 24 societies around the globe (n = 4,013) indicate that this generalization does not hold in the context of sibling relationships. In retrospective self-reports, females report being at least as aggressive as males toward their siblings, often more so. This holds for direct as well as indirect aggression, and for aggression between adult siblings as well as aggression that occurred during childhood. Consistent with prior research on sex differences, males reported engaging in more direct aggression toward nonkin than did females in the majority of societies. The results suggest that the dynamics of aggression within the family are different from those outside of it, and ultimately that understanding the role of sex in aggressive tendencies depends on context and target.

Cross-cultural validation and standardization of the Impostor-Profile 30

Ibrahim, F., Druică, E., Musso, F., ... & Karl, J. A. Current Psychology

Abstract

The impostor phenomenon describes a maladaptive personality style marked by persistent self-doubt and fear of being exposed as a fraud despite evident success. Despite its global relevance, the construct’s cross-cultural measurement invariance has not yet been empirically established. This study assessed the measurement invariance of the Impostor-Profile 30 across six European countries (N = 2472; 60.0\% female; Mage = 31.34, SD = 13.36), and standardized the instrument by deriving normative values. Multi-group confirmatory factor analyses supported partial scalar invariance across five countries (excluding Italy; CFI = 0.897, RMSEA = 0.060, SRMR = 0.090), strict invariance across genders (CFI = 0.932, RMSEA = 0.051, SRMR = 0.057), and metric invariance across age groups (CFI = 0.915, RMSEA = 0.055, SRMR = 0.070). Age-specific percentile ranks were derived to enable norm-based interpretation. These results confirm the cross-cultural equivalence of the IPP across five European countries, supporting its standardized use in psychological research and practice.

We report a series of meta-meta-analyses examining cultural variability in the Theory of Planned Behavior involving data from 956 studies across 54 countries (N = 151,177 to 245,694). Using multi-level analyses, we identified substantive variability within-country for all effects (variability at level 2 in 5 out of 6 analyses

Abstract

In this review, we bring together different strands of research focusing on rituals, social media and nature connectedness and interpret the intersection through a broad evolutionary niche construction lens. We argue that (a) humans have used rituals for a number of different purposes, with a particular emphasis on connecting human communities and managing emotional processes, (b) that these rituals were often centered around nature and seasonal cycles, and (c) that the runaway sociocultural niche construction driven by technological changes has disconnected humans from both the environment and traditional rituals, which has many unintended side effects and consequences. However, we also acknowledge the intrinsic importance of rituals for humans and the great potential of emerging rituals in the digital space to connect individuals with each other, to disseminate information on nature at scale and to link individuals and communities back to nature. We provide some speculation on how social media and digital technology could be used creatively by individuals and communities to connect them with nature again and therefore help to protect nature and identify areas for future transdisciplinary research and theory development.

Why We Need to Rethink Measurement Invariance: The Role of Measurement Invariance for Cross-Cultural Research

Fischer, R., Karl, J. A., Luczak-Roesch, M., & Hartle, L. Cross-Cultural Research

Abstract

Claims about human behavior have been hampered by limited availability of comparable data across cultures. Invariance testing has been proposed to address questions about the comparability of data, yet statistical methods have been challenged on various grounds across psychology and related fields. We highlight how current debates confuse distinct issues and fail to consider the role of data within science. We aim to overcome the impasse by a) summarizing various criticisms, b) distinguishing five mapping processes that occur during a typical research project and c) exploring how thinking about invariance as mapping can move current discussions forward. Specifically, we differentiate 1) mapping ideas to theoretical constructs and concepts, 2) mapping constructs to stimuli, 3) mapping participants’ responses to stimuli onto numerical representations, 4) testing internal relations of stimuli responses (the typical focus of statistical invariance testing) and 5) mapping empirical observations back to theoretical statements. We treat invariance testing as a theory-guided process that offers important insights about instruments, construct validity and psychological theories throughout the research process that are currently missed by focusing on only the statistical details. Psychological claims that are valid for all humans depend on questions of invariance in the broad sense that we outline here.

Wellbeing Dynamics Across Cultures During the Pandemic: A Five-Country Exploration

Hartle, L., Bortolini, T., Karl, J., Sokolov, B., & Fischer, R. International Journal of Psychology

Abstract

Wellbeing levels have been a global concern during the COVID-19 pandemic, but there is a lack of attention to invariance questions that allow a robust examination of wellbeing dynamics across cultures. Questions of temporal stability that are crucial for examining the impact of the pandemic on wellbeing have received even less attention. Some studies suggested that measures may not be stable after the onset of the pandemic. We examine invariance parameters, the factorial structure and variability of wellbeing variables (life satisfaction, pandemic worries, anxiety and depression screenings) across five different cultural contexts from 2020 to 2022 (N = 4387, total observations = 13,161). A three-factor model separating life satisfaction, worry and distress performed best in terms of model fit and parsimony. We observed scalar invariance across times and identified little variability of wellbeing measures during the pandemic, suggesting that wellbeing levels remained stable during the pandemic in each of the countries sampled. In contrast, we only identified metric invariance across countries at each time point, and found a weakening of correlations between life satisfaction and a depressive/anxious symptoms scale in lower income countries. We discuss implications of our findings for discussions of wellbeing dynamics.

Intercultural contact in the digital age: A review of emerging research on digitally mediated acculturation

Stuart, J., Ward, C., Karl, J. A., & Musizvingoza, R. advances.in/psychology

Abstract

Traditionally, intercultural contact has been constrained by physical proximity, but increased access to and use of digital technologies has broken down barriers and resulted in intercultural relations being increasingly digitally mediated. Technology has changed the acculturation experiences and outcomes of migrants, refugees, and international students who can access huge amounts of information throughout their migration journeys, maintain near-synchronous contact with their country of origin regardless of their location, and connect to individuals and groups both within and outside of the settlement culture. There is growing literature on the effects of social media on cultural adaptation and the interactions of diaspora communities online, yet there is a dearth of research that seeks to integrate this evidence into the broader acculturation literature. This narrative review addresses this gap, exploring three cases of digitally mediated acculturation among distinct migrant groups and types of digital technology: (1) mobile phones in refugee and asylum seekers’ migration journeys, (2) social media and the acculturative adjustment of international students, and (3) digital diasporas and the experiences of migrant groups. The findings not only highlight the impact of digital technologies on migrants’ acculturation experiences and adaptive outcomes but also suggest critical questions and possibilities for future acculturation research.

Abstract

Forming novel friendships is an important aspect of emerging adulthood, yet little is known about how emerging adults identify potential friends in contexts where behavioral information is limited. We propose that emerging adults use value congruence to guide friendship formation when observable behavioral cues are constrained. Using an experimental approach across two studies, we investigated whether friendship interest in an unfamiliar individual was dependent on value congruence. In Study 1 (N = 322), participants evaluated value-expressive self-descriptions of peers, while Study 2 (N = 451) examined friendship interest in the context of meeting someone online for the first time. Across both studies, we found robust associations between values-similarity and friendship interest for openness and conservation values, with more limited effects for self-transcendence values and minimal effects for self-enhancement values. Additionally, we found that vignettes expressing openness and self-transcendence values generated higher friendship interest overall compared to those expressing self-enhancement values. Study 2 also revealed evidence for value incongruence effects, with participants reporting lower friendship interest when exposed to opposing values. These findings suggest that value (in)congruence plays a meaningful role in friendship formation among emerging adults, particularly when observable behavioral information is limited, with effects being most pronounced for values emphasizing the contrast between novelty-seeking and self-restraint.

Abstract

As conversational artificial intelligence becomes increasingly embedded in everyday life, users routinely apply human social norms to text-based systems. Yet research on anthropomorphism in human–AI interaction has relied primarily on belief-based measures that do not capture how users behave toward AI during interaction. Across a large and diverse english sample (N = 933), we introduce and validate the Behavioral AI Anthropomorphism Scale (BAAS), the first behavioral self-report instrument assessing enacted reciprocity and socioemotional alignment with AI chatbots. Using a random-split sample approach, exploratory and confirmatory factor analyses supported a robust two-factor structure and a hierarchical higher-order model (CFI = .966, TLI = .949, RMSEA = .079, SRMR = .044), yielding strong reliability (α = .83 - .91; ω = .85 - .92) and discriminant validity (HTMT = .85) relative to psychological anthropomorphism. Behavioral anthropomorphism emerged as a central mechanism shaping trust: it explained incremental variance beyond belief-based anthropomorphism (ΔR² = .06–.07) and mediated associations between AI use frequency, gender attribution, and trust. Gender similarity effects further revealed that men anthropomorphized AI more when perceiving it as male, whereas women did so when perceiving it as female, with parallel patterns for trust. These findings demonstrate that trust in AI is grounded less in cognitive attributions and more in enacted social behavior. By identifying behavioral anthropomorphism as a key relational process in text-based AI interaction, this work provides a validated tool and a theoretical foundation for designing socially calibrated and user-sensitive conversational AI systems.

The impact of less severe intimate partner aggression on child conduct problems

Eisenbarth, H., Clavijo Saldias, K., Jose, P. E., Karl, J. A., & Waldie, K. E. JCPP Advances

Abstract

Background Significant intimate partner aggression (IPA) has been found to negatively impact outcomes of children, such as increased conduct problems (CP). However, it is unclear if forms of IPA that are less severe (e.g., shoving, pushing or yelling) have no, little, or substantial impact on child CP, which would indicate that the intensity (i.e., dosage) of IPA matters. In addition, it is unknown if the impact of IPA on child CP depends on the reporter (mother vs. partner) and on variables such as maternal depression and parenting. Methods We investigated the impact of IPA (both mother- and partner-reported), assessed during pregnancy and 9 months postpartum, on child CP at ages 2, 4.5, and 8 years. We also tested both the potential mediating role of maternal depression and moderating role of maternal warmth, reflecting risk and protective factors, respectively. Using longitudinal data from the Growing Up in New Zealand study, we tested path models with 5298 children. Results IPA predicted greater child CP for both mother- and partner-reported IPA, but at different age. Maternal depression partly mediated this effect, which was not moderated by maternal warmth. Conclusion These findings underscore the importance of exposure to IPA on child development and provides evidence for that impact on behaviour independent of the effects of maternal depression. Positive parenting like maternal warmth seems not to buffer those negative effects.

Abstract

At a time of growing global concern about climate change, mindfulness has been put forward as a potential tool to alleviate climate anxiety and engage people with environmental issues. However, climate anxiety is not a pathology to treat. Instead, climate anxiety is increasingly understood as reflecting a deep engagement with environmental concerns that motivates pro-environmental action. We question whether some aspects of mindfulness may be related to lower climate anxiety that flows into lower pro-environmental behavior.

Abstract

ObjectivesThe aim of the present study was to provide cross-cultural insight into the relationship between mindfulness, alexithymia, and stoic ideology.MethodUsing samples from New Zealand (n = 330) and Norway (n = 326), we estimated the facet-level network relationship of our target constructs, as well as the invariance of the estimated networks across cultural contexts.ResultsAcross cultural contexts, we found a consistent pattern of relationships in which both stoic ideology and alexithymia were negatively related to mindfulness. Negative relationships were especially pronounced between alexithymia and the mindfulness facets of Describing, Non-Judgement, and Acting with Awareness. This indicates that individual differences in these mindfulness facets might be more firmly rooted in difficulties identifying and describing emotions, compared to beliefs related to emotional suppression, as captured by stoic ideology. While the mindfulness facets showed overall expected patterns of relationships with both alexithymia and stoic ideology, Non-Reacting showed a divergent pattern. Non-Reacting was positively related to a tendency of Externally Oriented Thinking, as well as with Death-Acceptance, in both countries. Thus, this facet not only might capture Non-reactivity within the context of mindfulness, but also could potentially capture aspects of emotional avoidance.ConclusionsOverall, the study highlights that mindfulness could be influenced by both individual differences in emotion processing and cognitive beliefs about emotion processing. This accentuates the importance of examining both individual differences in, and cognitive beliefs about emotion regulation in research regarding mindfulness.

Tracing the evolution of personality cognition in early human civilisations: A computational analysis of the Gilgamesh epic

Du, A. H., Karl, J. A., Fetvadjiev, V., ... & Fischer, R. European Journal of Personality

Abstract

Assessing evolution of cognitive structures across historical periods has remained challenging in the absence of direct access to humans from the past. Overcoming some of these challenges, we examined shifts in the implicit cognitive structures in the Epic of Gilgamesh, which is one of the earliest surviving pieces of literature, circulating in various versions over a period of approx. 2000 years in ancient Mesopotamia. Using a canonical English translation, we applied natural language processing (NLP) and human coding to extract low-dimensional representations of the implicit personality structure in three different historical epochs. We found systematic shifts over time with increasing complexity and increasing resemblance of contemporary personality models in later periods. We discuss how lexical analyses of ancient texts using trait co-occurrence analyses can provide novel insights on the evolution of human behaviour of relevance for contemporary social and behavioural science and the study of ancient societies.

Abstract

We examined data from 59,508 participants across 63 countries to construct a measure of climate policy support and document associations with political orientation across the resulting scale. Preregistered analyses identified a three-factor model capturing support for tax-based, nature protection, and green transition policies. The scale demonstrated configural and metric invariance across all 63 countries, scalar invariance across 49 countries, and each subscale showed good reliability. There was substantial variability in the associations between political orientation and support for each policy domain: in many countries, conservatism predicted less support, but in a substantial minority, it predicted greater support. Policies were less supported in nations with higher emissions per capita, and there was some evidence that the negative associations between conservatism and policy support were stronger within higher emission nations. Rather than universally suppressing climate policy support, conservatism might be a more important barrier to climate policy support within high emission societies.

Emotion dysregulation in nonsuicidal self-injury: Dissociations between global self-reports and real-time responses to emotional challenge

Robinson, K., Cornes, J. P., Karl, J. A., Wilson, M. S., & Grimshaw, G. M. Journal of Affective Disorders

Abstract

Introduction Prominent theories of nonsuicidal self-injury (NSSI) propose that the behaviour is characterised by amplified emotional responses. However, little is known about how people who self-injure respond during emotional challenge. Methods We measured subjective and physiological responding (heart rate, heart rate variability, and electrodermal responding) among young adults with past-year NSSI (n = 51) and those with no lifetime NSSI (n = 50) during a resting baseline, a stress induction, and a post-stress resting phase. Participants reported the extent to which they spontaneously used cognitive reappraisal and expressive suppression during the post-stress phase. Two weeks later, a subset of the sample (n = 42) reported how they remembered feeling during the laboratory session. Results Although the NSSI group reported considerably greater emotion dysregulation than Controls, both groups showed similar subjective and psychological reactivity to, and recovery from, emotional challenge. Both groups used reappraisal and suppression regulation strategies following acute stress to a similar extent, and later came to remember the emotional challenge in a similar manner. Limitations Within the NSSI group, past-year self-injury tended to be infrequent and sporadic. Only 43.6\% of the sample participated in the follow-up survey assessing memory of emotional challenge. Conclusions Findings demonstrate that the role of emotion in NSSI is more complex than prominent theories can account for, raising substantial questions regarding the nature of emotion in NSSI. A more comprehensive understanding of the role of emotion in NSSI is needed to inform intervention strategies to better support people who self-injure.

Abstract

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.

Abstract

Many cancer treatments can lead to a disrupted body image and identity. One intervention to address these outcomes is therapeutic tattooing. However, despite the wide dissemination of this practice for cancer survivors (CSs), current research on it is lacking. This study aimed to identify tattoo artists’ (TAs’) perspectives on the types, impacts, barriers, and facilitators of therapeutic tattooing for CSs and the impact of doing this work on themselves.

Abstract

The relationship between values, well-being, and fit is incompletely understood. This study explored the structure of values as motivational goals for happiness and compared this structure with Schwartz’s general value structure. Furthermore, we examined whether or not congruence between endorsement of values in general and endorsement of values as goals for happiness increases individual hedonic/eudaimonic well-being. Undergraduate students (N=343) completed the Schwartz Values Survey, the Portrait Values Questionnaire, and measures of eudaimonic (Meaning in Life Questionnaire; Flourishing Scale) and hedonic well-being (Satisfaction with Life Scale; Subjective Happiness Scale). Multidimensional scaling was implemented to map value structures, which were subsequently compared using Procrustes rotation. Our congruence hypothesis was tested using response surface analysis. The results show that the structure of general values and the structure of values as goals for happiness were highly similar (ΦVTG = 0.93, ΦVGH = 0.95), implying that Schwartz’s Value Theory applies to values as goals for happiness and supporting our conceptualisation of values as motivational goals for happiness. Congruence hypothesis models contradicted our congruence hypothesis, indicating that factors other than reduced motivational conflict have bearing on the relationship between values and well-being. Implications of these findings and future directions are discussed.

Abstract

Imposter phenomenon is the experience of intellectual or occupational fraudulence despite evidence of success and represents an avoidant approach to goal setting. By contrast, purpose represents the motivation to pursue highly-valued life goals and is strongly associated with increased well-being. We hypothesised that impostor phenomenon would be negatively related to well-being; and that purpose at work would partially mediate this relationship. Participants (N=129; 62\% female) completed a survey which included measures of purpose at work, impostor phenomenon, and well-being. As hypothesised, increased impostor phenomenon was negatively associated with well-being. Purpose at work partially mediated this relationship resulting in decreased impostor phenomenon and increased eudemonic but not hedonic well-being. We provide support for previous studies which link impostor phenomenon to an avoidant approach to goal setting by inhibiting the use of active coping strategies. We encourage future interventions which aim to reduce imposter phenomenon and foster more purpose among working professionals.

Abstract

The Comprehensive Inventory of Mindfulness Experiences (CHIME) comprises 37 items over eight domains and was validated in German and English languages using Rasch methodology. However, the length of the scale might limit its application due to the response burden it places on participants, especially in studies that examine additional constructs. This study aimed to develop a short but comprehensive CHIME version using cutting-edge methodology.

Mapping the minds of spectators during an extreme ritual: a network perspective

Fischer, R., Sinwongsuwat, K., Tepsing, P., & Karl, J. Religion, Brain \& Behavior

Abstract

We study the mental maps of spectators using psychological network models during a large naturally occurring extreme ritual. Our aim was to identify the psychometric network structure of psychological reactions to an extreme ritual, and to investigate the core features of ritual cognition among its spectators. Participants who observed the Nine Emperor God (or Vegetarian) Festival (N = 1041 Taoist-Buddhists) completed measures of social, affective, behavioral and uncertainty cognitions. Applying undirected psychometric network models, we found that: 1) cognitions clustered in a small set of communities, and were 2) organized along two major dimensions (positive . negative valence, uncertainty beliefs ‘vs.’ uncertainty management). We argue that our study is an important step in theory building efforts, and that our findings offer insights for integrating theories of ritual. Thus, our study points towards new directions for theories of ritual by mapping the interdependence of psychological reactions and identifying the core cognition of a ritual.

Abstract

Physical appearance perfectionism and upward physical appearance comparisons have a potential role in explaining how the use of popular social networking sites can negatively impact a person's body image. Although there is considerable research on the relationship between body image and problematic Instagram usage, there is little reported on TikTok use. Therefore, the aim of this study was to explore the mediating relationship of physical appearance perfectionism and upward physical appearance comparison between problematic TikTok use and body appreciation. The sample included 185 TikTok users. Serial mediation analysis revealed a significant indirect negative relationship between problematic TikTok use and body appreciation through physical appearance perfectionism, but not upward physical appearance comparison, or physical appearance perfectionism and upward physical appearance comparison in serial. Thus, with the rapid growth of TikTok, this study highlights the importance of identifying the individuals who may be more vulnerable to the effects of the app. We suggest possible practice implications such as the implementation of screening strategies to identify those high in physical appearance perfectionism, and the development of workshops aimed at promoting positive body image in the face of SNS use.

The Coronavirus Anxiety Scale: Cross-national measurement invariance and convergent validity evidence

Jovanović, V., Rudnev, M., Abdelrahman, M., ... & Et Al, n. Psychological Assessment

Abstract

Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries (Ntotal = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries. Partial scalar invariance was supported in a subset of 56 countries. To ensure the robustness of results, given the unbalanced samples, we employed resampling techniques both with and without replacement and found the results were more stable in larger samples. The alignment procedure demonstrated a high degree of measurement invariance with 9\% of the parameters exhibiting noninvariance. We also conducted simulations of alignment using the parameters estimated in the current model. Findings demonstrated reliability of the means but indicated challenges in estimating the latent variances. Strong positive correlations between CAS and FCV-19S estimated with all three different approaches were found in most countries. Correlations of CAS and SWLS-3 were weak and negative but significantly differed from zero in several countries. Overall, the study provided support for the measurement invariance of the CAS and offered evidence of its convergent validity while also highlighting issues with variance estimation.

Trust in government moderates the association between fear of COVID-19 as well as empathic concern and preventive behaviour

Karakulak, A., Tepe, B., Dimitrova, R., ... & Rudnev, M. Communications Psychology

Abstract

With the COVID-19 pandemic, behavioural scientists aimed to illuminate reasons why people comply with (or not) large-scale cooperative activities. Here we investigated the motives that underlie support for COVID-19 preventive behaviours in a sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease with support towards preventive COVID-19 behaviours would be moderated by trust in the government. Results suggest that the association between fear of disease and support for COVID-19 preventive behaviours was strongest when trust in the government was weak (both at individual- and country-level). Conversely, the association with empathic prosocial concern was strongest when trust in the government was high, but this moderation was only found at individual-level scores of governmental trust. We discuss how motivations may be shaped by socio-cultural context, and outline how findings may contribute to a better understanding of collective action during global crises.

Abstract

The research examined perceived national norms for multiculturalism, Multicultural Contact (MC), Multicultural Ideology (MI) and Multicultural Policies and Practices (MPP), as associated with well-being in a community sample. One hundred and twenty-five British Indians and 250 British Whites completed an online survey with measures of Normative Multiculturalism, belonging, and psychological well-being (positive affect, flourishing, and life satisfaction). A multi-group mediational model was tested with direct and indirect (via belonging) paths to well-being. Results demonstrated significant direct and indirect associations of MC on well-being for Indians and indirect associations for Whites. MPP produced the same indirect pathways, but only for Indians. MI was not significantly related either to belonging or well-being. The findings are discussed in relation to broader theorizing on multiculturalism and their practical implications in the British socio-political context.

Evidence of Validity Does not Rule out Systematic Bias: A Commentary on Nomological Noise and Cross-Cultural Invariance

Fischer, R., Karl, J. A., Fontaine, J. R. J., & Poortinga, Y. H. Sociological Methods \& Research

Abstract

We comment on the argument by Welzel, Brunkert, Kruse and Inglehart (2021) that theoretically expected associations in nomological networks should take priority over invariance tests in cross-national research. We agree that narrow application of individual tools, such as multi-group confirmatory factor analysis with data that violates the assumptions of these techniques, can be misleading. However, findings that fit expectations of nomological networks may not be free of bias. We present supporting evidence of systematic bias affecting nomological network relationships from a) previous research on intelligence and response styles, b) two simulation studies, and c) data on the choice index from the World Value Survey (WVS). Our main point is that nomological network analysis by itself is insufficient to rule out systematic bias in data. We point out how a thoughtful exploration of sources of biases in cross-national data can contribute to stronger theory development.

A many-analysts approach to the relation between religiosity and well-being

Hoogeveen, S., Sarafoglou, A., Aczel, B., ... & Wagenmakers, E. Religion, Brain \& Behavior

Abstract

The relation between religiosity and well-being is one of the most researched topics in the psychology of religion, yet the directionality and robustness of the effect remains debated. Here, we adopted a many-analysts approach to assess the robustness of this relation based on a new cross-cultural dataset (N=10,535 participants from 24 countries). We recruited 120 analysis teams to investigate (1) whether religious people self-report higher well-being, and (2) whether the relation between religiosity and self-reported well-being depends on perceived cultural norms of religion (i.e., whether it is considered normal and desirable to be religious in a given country). In a two-stage procedure, the teams first created an analysis plan and then executed their planned analysis on the data. For the first research question, all but 3 teams reported positive effect sizes with credible/confidence intervals excluding zero (median reported β=0.120). For the second research question, this was the case for 65\% of the teams (median reported β=0.039). While most teams applied (multilevel) linear regression models, there was considerable variability in the choice of items used to construct the independent variables, the dependent variable, and the included covariates.

Abstract

There have been long-standing debates on the relationships between values as important motivational goals and well-being. We used a longitudinal network perspective to examine how value states and well-being are related over time, separating within-person lagged, within-person contemporaneous, and between-person perspectives. A total of 227 young adults (1,007 observation points) participated in the study and rated their values states and well-being over a 6-day period. Value-well-being linkages varied across levels of analysis for participants who reported at least three times (N = 187). Momentary self-transcendence values predicted both simultaneous and subsequent well-being. The motivationally opposing self-enhancement values negatively related to well-being contemporaneously within person. This supports clinical research emphasizing that pursuing other-focused values increases well-being and highlights the importance of values for well-being. At the same time, individual differences in self-transcendence values were negatively related to well-being, supporting previous value models. In line with self-determination theory, openness to change values were related to well-being at both the within- and between-person level. These patterns unify diverging theoretical positions, and suggest that different dynamics operate across levels (within-person lagged or contemporaneous vs. between-person). We also provide new insights into value dynamics by describing how distributions of value states may give rise to more stable value differences between individuals. Overall, within- and between-person associations differed suggesting greater attention to person-level processes is needed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract

This study aimed to explore the potential buffering effect of trait mindful acceptance and the exacerbating effect of trait mindful attention monitoring on the relationship between organizational injustice and burnout. A cross-sectional survey was conducted with 139 employees who completed measures of burnout, organizational injustice, and trait mindfulness. A moderated regression analysis was used to examine the relationships between burnout (DV), organizational injustice (IV), trait mindful acceptance and trait mindful attention monitoring (moderators). The results revealed a significant positive association between organizational injustice and burnout (β = .51, standardized 95\% CI [.35, .67], p \< 0.001) with an R2 = .26. However, trait mindful acceptance did not significantly buffer the relationship between organizational injustice and burnout (β = -.05, standardized 95\% CI [-.21, .1], p = .49), while mindful attention monitoring did not significantly exacerbate impact organizational injustice on burnout (β = -.03, standardized 95\% CI [-.17, .11], p = .65) with the adjusted R2 = .57. The results, while not significant, suggest that trait mindful acceptance may not buffer against the impact of organizational injustice on burnout, though trait mindful attention monitoring may indeed exacerbate this relationship. Alongside contributing to psychological theory such as Monitoring and Acceptance theory, the current study provides a unique framework for combating the negative impact of organizational injustice on burnout in the workplace.

Abstract

There has been concern about ideological basis and possible discrimination in text generated by Large Language Models (LLMs). We test possible value biases in ChatGPT using a psychological value theory. We designed a simple experiment in which we used a number of different probes derived from the Schwartz basic value theory (items from the revised Portrait Value Questionnaire, the value type definitions, value names). We prompted ChatGPT via the OpenAI API repeatedly to generate text and then analyzed the generated corpus for value content with a theory-driven value dictionary using a bag of words approach. Overall, we found little evidence of explicit value bias. The results showed sufficient construct and discriminant validity for the generated text in line with the theoretical predictions of the psychological model, which suggests that the value content was carried through into the outputs with high fidelity. We saw some merging of socially oriented values, which may suggest that these values are less clearly differentiated at a linguistic level or alternatively, this mixing may reflect underlying universal human motivations. We outline some possible applications of our findings for both applications of ChatGPT for corporate usage and policy making as well as future research avenues. We also highlight possible implications of this relatively high-fidelity replication of motivational content using a linguistic model for the theorizing about human values.

Taking a fresh look at the CQ-personality mediation hypothesis: a network perspective

Fischer, R. & Karl, J. A. Handbook of Cultural Intelligence Research

PDF
Abstract

We present new perspectives on the mediation hypothesis between personality, CQ and work behavior. We conducted a psychometric network analysis with data from 760 individuals in New Zealand. Our network identified two major dimensions, differentiating constructs along activity (behavior vs emotional constructs) and valence (contrasting negatively valenced constructs such as deviance from CQ and personality). Focusing on the mediation hypothesis, the results suggest that CQ and openness personality traits formed a single community cluster and that openness personality traits were more strongly related to other work attitudes and work behaviors. Overall, we found little evidence for possible mediation. Instead, CQ may form part of a larger individual difference construct cluster that captures desirable capabilities for organizations. We encourage further analyses using psychometric network models to provide deeper insights into how CQ may function in work organizations.

On the relationship between valence and arousal in samples across the globe

Yik, M., Mues, C., Sze, I. N. L., ... & Russell, J. A. Emotion (Washington, D.C.)

Abstract

Affect is involved in many psychological phenomena, but a descriptive structure, long sought, has been elusive. Valence and arousal are fundamental, and a key question-the focus of the present study-is the relationship between them. Valence is sometimes thought to be independent of arousal, but, in some studies (representing too few societies in the world) arousal was found to vary with valence. One common finding is that arousal is lowest at neutral valence and increases with both positive and negative valence: a symmetric V-shaped relationship. In the study reported here of self-reported affect during a remembered moment (N = 8,590), we tested the valence-arousal relationship in 33 societies with 25 different languages. The two most common hypotheses in the literature-independence and a symmetric V-shaped relationship-were not supported. With data of all samples pooled, arousal increased with positive but not negative valence. Valence accounted for between 5\% (Finland) and 43\% (China Beijing) of the variance in arousal. Although there is evidence for a structural relationship between the two, there is also a large amount of variability in this relation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Abstract

Abstract The current study investigated the motives that underlie support for COVID-19 preventive behaviorsin a large, cross-cultural sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease, with support towards preventive COVID-19 behaviors would be moderated by the individual-level and country-level trust in the government. Results suggest that the association between fear of disease and support for COVID-19 preventive behaviors was strongest when trust in the government was weak (both at individual and country-level). Conversely, the association with empathic prosocial concern was strongest when trust was high, but this moderation was only found at individual-level scores of governmental trust. We discuss how both fear and empathy motivations to support preventive COVID-19 behaviors may be shaped by socio-cultural context, and outline how the present findings may contribute to a better understanding of collective action during global crises.

Abstract

Substantial efforts have been made to develop comprehensive dictionaries of personality traits in many languages. Nevertheless, given that what is important and salient in individuals’ lived experience might be changing over time, this raises the question about the long-term usefulness of ‘off-the-shelf’ dictionaries developed decades ago. In the current study we used a bottom-up approach to create a large population-specific lexicon of personality terms. We subsequently examined the overlap and sensitivity to extract implicit personality of this dictionary compared to an established trait dictionary in the same language. Overall, we found that the two dictionaries only showed limited overlap with a pronounced divergence in emotionality (Neuroticism) and social aspects (Agreeableness) of personality. In addition to this, we found that while the implicit personality extracted from self-descriptions using the established dictionary showed alignment with participants self-rated personality, especially in Extraversion, Agreeableness, and Neuroticism, the population-specific dictionary showed a significantly greater alignment between implicit and self-rated personality. In summary, our current study highlights the need to extend our thinking about the psycholexical hypothesis, moving away from assumptions of time invariant language encoding to more explicitly recognizing the temporal dynamics underpinning the expression and use of personality trait terms.

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

Hornsey, M. J., Pearson, S., Kang, J., ... & Bastian, B. European Journal of Social Psychology

Abstract

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.

Abstract

We report systematic variability in the psychometric properties of a brief personality inventory during the early stages of the COVID-19 pandemic. Drawing upon recent discussions about the universality vs cultural relativism of personality measures, we review and comparatively test theories predicting systematic variability in personality measurement across cultures using an established brief personality measure applied to population samples in 16 nations during the first wave of the COVID-19 pandemic (N = 35,052). We found systematic variation in factor replicability and effective dimensionality. In line with previous theorizing, factors replicated better in contexts with greater niche diversity. Examining possible drivers underlying this association, the investigation of the individual components in the niche construction index suggested that life expectancy and to a lesser degree economic complexity are associated with greater personality structure differentiation. Population-level indicators of acute threat due to COVID-19 did not show credible effects. These patterns suggest that a) investigation of personality structure in population samples can provide useful insights into personality dynamics, b) socioecological factors have a systematic impact on survey responses, but c) we also need better theorizing and research about both personality and culture to understand how niche construction dynamics operate.

In search of mindfulness: a review and reconsideration of cultural dynamics from a cognitive perspective

Karl, J. A., Johnson, F. N., Bucci, L., & Fischer, R. Journal of the Royal Society of New Zealand

Abstract

We provide a critical review of mindfulness research, focusing on three core areas and questions. First, a meta-review and bibliometric analysis on mindfulness research trends identified a large number of meta-analyses published in the last 20 years, which tend to show positive effects on average, despite continuing questions on research quality, unclear pathways and uncertainty about the efficacy of individual practice components. Second, we briefly review current conceptualizations of mindfulness as both a practice and a trait (individual difference variable) and how these interpretations may align with the diverse Buddhist philosophical roots. We examine the multidimensionality of mindfulness within and across cultural contexts, which points to conflicts between bottom-up (functionalist) and top-down (culturally relativist meaning-system) interpretations. In order to reconcile these interpretations, we introduce a predictive coding approach which allows integrating bottom-up biological and individual difference dynamics with top-down normative and cultural influences. Finally, we apply these ideas to two examples of how mindfulness components might be present in different cultural practices: (a) stoic philosophy and (b) established concepts from Te Ao Māori. We argue that recontextualizing mindfulness in culturally relevant terms provides opportunities to enrich both mindfulness theory and practice, allowing for an integration of cognitive-functional and cultural relativist positions.

Misunderstood Stoicism: The negative Association Between Stoic Ideology and well-Being

Karl, J. A., Verhaeghen, P., Aikman, S. N., ... & Fischer, R. Journal of Happiness Studies

Abstract

Ancient philosophy proposed a wide range of possible approaches to life which may enhance well-being. Stoic philosophy has influenced various therapeutic traditions. Individuals today may adopt an approach to life representing a naive Stoic Ideology, which nevertheless reflects a misinterpretation of stoic philosophy. How do these interpretations affect well-being and meaning in life? We examine the differential effects of Stoic Ideology on eudaimonic versus hedonic well-being across three cultural contexts. In this pre-registered study, across samples in New Zealand (N = 636), Norway (N = 290), and the US (N = 381) we found that a) Stoic Ideology can be measured across all three contexts and b) Converging evidence that Stoic Ideology was negatively related to both hedonic well-being and eudaimonic well-being. Focusing on specific relationships, we found especially pronounced effects for Taciturnity (the desire to not express emotions) and Serenity (the desire to feel less emotions). Despite being a misinterpretation of stoic philosophy, these findings highlight the important role of individuals’ orientations to emotional processing for well-being.

Abstract

We use a cultural psychology approach to examine the relevance of the Health Belief Model (HBM) for predicting a variety of behaviors that had been recommended by health officials during the initial stages of the Covid-19 lockdown for containing the spread of the virus and not overburdening the health system in Europe. Our study is grounded in the assumption that health behavior is activated based on locally relevant perceptions of threats, susceptibility and benefits in engaging in protective behavior, which requires careful attention to how these perceptions might be structured and activated. We assess the validity of the HBM in two European countries that have been relatively understudied, using simultaneous measurements during acute periods of infection in Romania and Italy. An online questionnaire provided a total of (N = 1863) valid answers from both countries. First, to understand individual difference patterns within and across populations, we fit a General Linear Model in which endorsement was predicted by behavior, country, their interaction, and a random effect for participants. Second, we assess the effect of demographics and health beliefs on prevention behaviors by fitting a multi-group path model across countries, in which each behavior was predicted by the observed health belief variables and demographics. Health beliefs showed stronger relationships with the recommended behaviors than demographics. Confirming previously reported relationships, self-efficacy, perceived severity, and perceived benefits were consistently related to the greater adoption of individual behaviors, whereas greater perceived barriers were related to lower adoption of health behaviors. However, we also point to important location specific effects that suggest that local norms shape protective behavior in highly contextualized ways.

Abstract

Are affective states influencing state mindfulness and can this explain the link between personality and mindfulness? Mindfulness is commonly thought to decrease negative affect, but a number of studies have reported reductions in mindfulness in negative affect situations. This highlights a potential mechanism explaining previously observed negative relationships between individual differences such as Neuroticism and mindfulness, via their shared relationship with negative affect.

Family still matters: Human social motivation across 42 countries during a global pandemic

Pick, C. M., Ko, A., Wormley, A. S., ... & Varnum, M. E. W. Evolution and Human Behavior

Abstract

The COVID-19 pandemic caused drastic social changes for many people, including separation from friends and coworkers, enforced close contact with family, and reductions in mobility. Here we assess the extent to which people's evolutionarily-relevant basic motivations and goals—fundamental social motives such as Affiliation and Kin Care—might have been affected. To address this question, we gathered data on fundamental social motives in 42 countries (N = 15,915) across two waves, including 19 countries (N = 10,907) for which data were gathered both before and during the pandemic (pre-pandemic wave: 32 countries, N = 8998; 3302 male, 5585 female; Mage = 24.43, SD = 7.91; mid-pandemic wave: 29 countries, N = 6917; 2249 male, 4218 female; Mage = 28.59, SD = 11.31). Samples include data collected online (e.g., Prolific, MTurk), at universities, and via community sampling. We found that Disease Avoidance motivation was substantially higher during the pandemic, and that most of the other fundamental social motives showed small, yet significant, differences across waves. Most sensibly, concern with caring for one's children was higher during the pandemic, and concerns with Mate Seeking and Status were lower. Earlier findings showing the prioritization of family motives over mating motives (and even over Disease Avoidance motives) were replicated during the pandemic. Finally, well-being remained positively associated with family-related motives and negatively associated with mating motives during the pandemic, as in the pre-pandemic samples. Our results provide further evidence for the robust primacy of family-related motivations even during this unique disruption of social life.

Fundamental social motives measured across forty-two cultures in two waves

Pick, C. M., Ko, A., Kenrick, D. T., ... & Varnum, M. E. W. Scientific Data

Abstract

How does psychology vary across human societies? The fundamental social motives framework adopts an evolutionary approach to capture the broad range of human social goals within a taxonomy of ancestrally recurring threats and opportunities. These motives—self-protection, disease avoidance, affiliation, status, mate acquisition, mate retention, and kin care—are high in fitness relevance and everyday salience, yet understudied cross-culturally. Here, we gathered data on these motives in 42 countries (N = 15,915) in two cross-sectional waves, including 19 countries (N = 10,907) for which data were gathered in both waves. Wave 1 was collected from mid-2016 through late 2019 (32 countries, N = 8,998; 3,302 male, 5,585 female; Mage = 24.43, SD = 7.91). Wave 2 was collected from April through November 2020, during the COVID-19 pandemic (29 countries, N = 6,917; 2,249 male, 4,218 female; Mage = 28.59, SD = 11.31). These data can be used to assess differences and similarities in people’s fundamental social motives both across and within cultures, at different time points, and in relation to other commonly studied cultural indicators and outcomes.

Opportunities and Challenges of Extracting Values in Autobiographical Narratives

Fischer, R., Karl, J., Fetvadjiev, V., Grener, A., & Luczak-Roesch, M. Frontiers in Psychology

Abstract

We report three studies in which we applied a value dictionary to narratives. Our objective was to test a theory-driven value dictionary for extracting value information from autobiographical and narrative texts. In Study 1 (N=106) and 2 (N=152), participants wrote short autobiographical narratives and in Study 3 (N=150), participants wrote narratives based on ambiguous stimuli. Participants in all three studies also completed the Portrait Value Questionnaire as a self-report measure of values. Overall, our results demonstrate that it is possible to extract value-relevant information from these narratives. Extracted values from autobiographical narratives showed average correlations of .07 (study 1) and .12 (study 2) with self-reports compared to an average correlation of .01 for the extracted values from implicit motive tasks (study 3). The correlations with self-reports were in line with previous validation studies. The most salient values in narratives diverged somewhat, with a stronger emphasis on Achievement values compared to self-reports, probably due to the nature of salient episodes within one’s life that require demonstrating success according to social standards. Benevolence values were consistently most important in both self-ratings and text-based scoring. The value structure emerging from narratives diverged from the theoretically predicted structure, yet broad personally vs socially focused value dimensions were qualitatively discernible. We highlight opportunities and challenges for future value research using autobiographical stories.

Human values and basic philosophical beliefs

Karl, J. A. & Fischer, R. New Ideas in Psychology

Abstract

Objectives We present the first investigation into the relationship between basic human values and two core lay-belief systems: Free-Will and Mind-Body beliefs. Methods We gathered data from two samples (Total N = 509) responding to measures on basic human values, mind-body beliefs, and free-will beliefs. Results We found that basic values were substantially related to lay-perceptions about mind-body distinctions and beliefs about free-will. Specifically, we found that Self-Enhancement and Conservatism values were positively related to Monist and Deterministic Beliefs. Interestingly, we found that participants that endorsed Self-Enhancement and Conservatism values were more likely to integrate opposing beliefs and also endorsed Dualistic and Free-Will beliefs, albeit to a lesser extent. Finally, we found that Openness was positively related to both beliefs about mind-body Emergentism and Free-Will. Conclusions Overall, our study provides new insights for linking philosophy and psychology, specifically by linking lay philosophical attitudes high-level abstract beliefs and how they may be linked to motivational goals.

Kiwi Diwali: a longitudinal investigation of perceived social connection following a civic religious ritual

Piven, S. D., Fischer, R., Shaver, J. H., ... & Bulbulia, J. Religion, Brain \& Behavior

Abstract

Religious rituals are ubiquitous. Recent research indicates they can powerfully affect social connection, increasing collective sentiments and behaviors. However, the extent to which these effects depend on religious commitment remains unclear. Here, we use longitudinal data to investigate this question in a natural ritual setting by comparing the responses of religiously committed Hindus and non-Hindus immediately after a public Diwali celebration in New Zealand, and for two weeks following. Effects of time and level of religious commitment are assessed on five targets that measure reported social connection of participants to themselves and to specific groups: “Myself,” “My family and friends,” “Work colleagues/university peers,” “People who celebrate Diwali,” and “Humanity in general.” We find that participation in the civic religious ritual affects social connection of all participants, with stronger effects among religiously committed Hindus. Private religious behavior appears integral to the mechanisms underpinning the amplification of solidarity at public rituals, as we find separation in the level of reported social connection to Diwali celebrants between practicing and non-practicing Hindus. Though religious commitment leads to greater perceived social connection, this study additionally demonstrates that in a religiously diverse democracy, a civic religious ritual may foster greater democratic unions across religious differences.

Perceiving societal pressure to be happy is linked to poor well-being, especially in happy nations

Dejonckheere, E., Rhee, J. J., Baguma, P. K., ... & Bastian, B. Scientific Reports

Abstract

Happiness is a valuable experience, and societies want their citizens to be happy. Although this societal commitment seems laudable, overly emphasizing positivity (versus negativity) may create an unattainable emotion norm that ironically compromises individual well-being. In this multi-national study (40 countries; 7443 participants), we investigate how societal pressure to be happy and not sad predicts emotional, cognitive and clinical indicators of well-being around the world, and examine how these relations differ as a function of countries’ national happiness levels (collected from the World Happiness Report). Although detrimental well-being associations manifest for an average country, the strength of these relations varies across countries. People’s felt societal pressure to be happy and not sad is particularly linked to poor well-being in countries with a higher World Happiness Index. Although the cross-sectional nature of our work prohibits causal conclusions, our findings highlight the correlational link between social emotion valuation and individual well-being, and suggest that high national happiness levels may have downsides for some.

Multilevel issues in organizations and culture: a review of theoretical and methodological innovations for the study of national and organizational culture

Fischer, R., Karl, J., Rensburg, G. J. v., & Ferreira, M. C. Handbook of Research Methods for Organisational Culture

PDF
Abstract

Organizational cultures are embedded within larger cultural systems, including national culture. Here, we provide a short review and discussion of the intersection between national and organizational culture. One central focus of our review is on the multilevel structure of culture, which spans from very small units such as teams to global entities such as geographical regions. At the national level, Hofstede's (1980) seminal work continues to be a central influence on theorizing and research on national culture, therefore, we provide a brief review of his work and how it continues to shape work, such as the GLOBE project and Schwartz' value theory. At the same time, the notion of bounded cultural units tied to nations has been challenged and we discuss some of those challenges. We also briefly outline some of the measures and approaches to organizational culture measurement. We then discuss theoretical and methodological issues of culture at both organizational and national level and how they are interlinked. In the final section, we will reiterate a few core theoretical methodological advances and challenges for future research on the intersection between organizations and culture, especially focusing on complex systems and evolutionary theory approaches.

The Next Challenges for Measuring Organizational Behavior Constructs

Fischer, R. & Karl, J. A. Assessing Organizational Behaviors: A Critical Analysis of Measuring Instruments

Abstract

We will critically review and discuss some broader trends in the literature regarding measurement in organizational behavior research. Our comments will center around three core interrelated points. First, the increasing use of wearable technology and big data is opening up new avenues for measuring organizational behavior constructs. Second, we will discuss network models as one of the conceptual and statistical innovations that arose out of the big data revolution and highlight their potential impact on organizational theory and measurement. Third, greater attention to cross-cultural issues is needed in a more global working environment. All these points are linked, and bringing these various points back together, we will engage with more conceptual questions about the nature and future of organizational behavior measures.

Revisiting the five-facet structure of mindfulness

Karl, J. A. & Fischer, R. Measurement Instruments for the Social Sciences

Abstract

The current study aimed to replicate the development of the Five-Facet Mindfulness Questionnaire (FFMQ) in a sample of 399 undergraduate students. We factor analyzed the Mindful Attention and Awareness Questionnaire (MAAS), the Freiburg Mindfulness Scale, the Southampton Mindfulness Questionnaire (SMQ), the Cognitive Affective Mindfulness Scale Revised (CAMS-R), and the Kentucky Inventory of Mindfulness Skills (KIMS), but also extended the analysis by including a conceptually related measure, the Philadelphia Mindfulness Scale (PHLMS), and a conceptually unrelated measure, the Langer Mindfulness Scale (LMS). Overall, we found a partial replication of the five-factor structure, with the exception of non-reacting and non-judging which formed a single factor. The PHLMS items loaded as expected with theoretically related factors, whereas the LMS items emerged as separate factor. Finally, we found a new factor that was mostly defined by negatively worded items indicating possible item wording artifacts within the FFMQ. Our conceptual validation study indicates that some facets of the FFMQ can be recovered, but item wording factors may threaten the stability of these facets. Additionally, measures such as the LMS appear to measure not only theoretically, but also empirically different constructs.

Tracing Personality Structure in Narratives: A Computational Bottom–Up Approach to Unpack Writers, Characters, and Personality in Historical Context

Fischer, R., Karl, J. A., Luczak–Roesch, M., Fetvadjiev, V. H., & Grener, A. European Journal of Personality

Abstract

We present a new method for personality assessment at a distance to uncover personality structure in historical texts. We focus on how two 19th century authors understood and described human personality; we apply a new bottom–up computational approach to extract personality dimensions used by Jane Austen and Charles Dickens to describe fictional characters in 21 novels. We matched personality descriptions using three person–description dictionaries marker scales as reference points for interpretation. Factor structures did not show strong convergence with the contemporary Big Five model. Jane Austen described characters in terms of social and emotional richness with greater nuances but using a less extensive vocabulary. Charles Dickens, in contrast, used a rich and diverse personality vocabulary, but those descriptions centred around more restricted dimensions of power and dominance. Although we could identify conceptually similar factors across the two authors, analyses of the overlapping vocabulary between the two authors suggested only moderate convergence. We discuss the utility and potential of automated text analysis and the lexical hypothesis to (i) provide insights into implicit personality models in historical texts and (ii) bridge the divide between idiographic and nomothetic perspectives. © 2020 European Association of Personality Psychology

Abstract

We conducted a rapid review and quantitative summary of meta-analyses that have examined interventions which can be used by individuals during quarantine and social distancing to manage anxiety, depression, stress and subjective well-being. A literature search yielded 34 meta-analyses (total number of studies k = 1,390, n = 145,744) that were summarized. Overall, self-guided interventions showed small to medium effects in comparison to control groups. In particular, self-guided therapeutic approaches (including cognitive-behavioral, mindfulness, and acceptance-based interventions), selected positive psychology interventions, and multi-component and activity-based interventions (music, physical exercise) showed promising evidence for effectiveness. Overall, self-guided interventions on average did not show the same degree of effectiveness as traditional guided individual or group therapies. There was no consistent evidence of dose effects, baseline differences and differential effectiveness of eHealth interventions. More research on the effectiveness of interventions in diverse cultural settings is needed.

Time investments in rituals are associated with social bonding, affect and subjective health: a longitudinal study of Diwali in two Indian communities

Singh, P., Tewari, S., Kesberg, R., ... & Fischer, R. Philosophical Transactions of the Royal Society B: Biological Sciences

Abstract

Rituals are performed within specific socio-ecological niches, yet the different effects of the same ritual form across different niches (community contexts) remains unclear. Here, using longitudinal measures over a two-week period during Diwali (the Indian festival of light), we investigate the relationship between ritual time allocation and social cohesion in two Indian communities. First, the positive effects of ritual on social bonding, perceived health and affect were highest on the focal day of the festival. Second, we observed anticipatory effects of ritualistic commitment on affect prior to the main day of the festival. Third, social bonding patterns were similar in the two Indian settings, indicating that Diwali fosters social cohesion across diverse social ecologies (cultural niches). However, individually focused emotional benefits appear to dampened in more cosmopolitan environments. Finally, time investments reveal diminishing marginal utilities for ritual activities on social cognition. Ritual time investments were linked to greater affect and family cohesion up to a certain limit. We argue that attention to the diminishing returns of ritual time investments on social cohesion across diverse human ecologies is an important horizon for future cross-cultural investigations.This article is part of the theme issue ‘Ritual renaissance: new insights into the most human of behaviours’.

The network architecture of individual differences: Personality, reward-sensitivity, and values✰

Fischer, R. & Alfons Karl, J. Personality and Individual Differences

Abstract

Individual differences in behavioral dispositions, values and motivation systems have been investigated in relative isolation from each other. We investigated the network structure of indicators derived from Reinforcement Sensitivity Theory, Five-Factor Model and Basic individual values in a large sample of young adults (N = 749). The network showed evidence of a small world structure indicating a small number of densely connected networks is sufficient to describe human personality. We identified a number of nodes (indicators) that were central within the network. An Exploratory Graph Analysis suggested ten distinct network clusters, which varied in terms of behavioral approach versus inhibition; exploration vs constraint and self/ego vs social orientation, demonstrating the complexity of individual differences from a motivational-situational perspective. A more complex dimensional exploration of personality networks allows for a more nuanced understanding of how personality systems can be motivated within specific environments and towards different internal or external targets.

How normative multiculturalism relates to immigrant well-being

Ward, C., Kim, I., Karl, J. A., Epstein, S., & Park, H. Cultural Diversity \& Ethnic Minority Psychology

Abstract

OBJECTIVES: In this study we examine the relationship between contextual factors, that is, perceived multicultural norms, and immigrant well-being. Specifically, we test a model whereby each of the three dimensions of normative multiculturalism, perceived Multicultural Ideology, Multicultural Policies and Practices, and Multicultural Contact, positively predicts immigrant well-being both directly and indirectly via belongingness. METHOD: Korean immigrants in New Zealand (N = 306, 56\% female) participated in the research. Their average age was 31.17 (SD = 10.46), and the average length of residence was 10.04 years (SD = 7.21). Participants completed a survey that included the Normative Multiculturalism Scale along with measures of belonging and well-being (flourishing, life satisfaction, and positive affect). RESULTS: Structural equation modeling showed that perceived normative Multicultural Policies and Practices exerted a direct positive effect on well-being and an indirect positive effect via belongingness; Multicultural Ideology exerted only an indirect effect; and Multicultural Contact did not significantly relate to belongingness or subjective well-being. IMPLICATIONS: The results are discussed in terms of everyday experiences of intercultural encounters, social norms and the contextual influences of diversity climates, as well as the importance of distinguishing the defining features of multiculturalism in diversity science research. We also propose that multicultural norm setting and norms marketing may lead to positive social and psychological outcomes for immigrants.

Abstract

We tested whether various established priming methods affected personal values and behavioral choices in two experiments. We also aimed to test whether an activation of values through priming might shed some light on value-behavior linkages. Using a large online sample (pre-registration: https://osf.io/nz8ak/?view\_only=b9110537370444d98d2b22dcf5f0774e) and a general population sample (pre-registration: https://osf.io/4juxx/?view\_only=a4f0b53183824c56a90310497195d2d7), we did not find strong and consistent priming effects on either values or behavior/behavioral intentions. Nevertheless, in line with previous research, we found that values correlated with behavioral choices. Therefore, our study casts further doubt on the effectiveness of priming for activating social psychological constructs (e.g., values). Our correlational results show that values and behavior are correlated, but in the absence of experimental evidence, the causal direction of any value-behavior correlations need to be interpreted cautiously because causality (values predicting behavior) cannot be assumed.

Abstract

Norms have emerged as a central concept across various fields of psychology. In social psychology, norms have been important to predict intentions and behavior, but cultural variability has not been examined. In cultural psychology, norms have also played a central role in explained cultural differences. In contrast, to date, variability in norm-intention and norm-behavior relationships has not been systematically investigated. Any systematic variability may be challenging to both social and cultural psychology. We re-analyzed effect sizes taken from five previously published meta-analyses using a fixed-effects model and demonstrate that the relative strength of norm-intention and norm-behavior correlations in this sample of previously published studies are systematically higher in less economically developed societies. We also found significant, but weaker, effects for individualism, tightness–looseness and monumentalism vs flexibility. Meanwhile, behavior domain effects also emerged, which suggests that norms are behavior specific. Norms effects systematically vary across previously published studies, implying that more attention is needed to investigate culturally conditioned domain and behavior effects.

The retracted previous version featured incorrect results.

Individual Differences and Mindfulness

Karl, J. A. & Fischer, R.

Abstract

What makes some people more mindful than others? Previous research has indicated that dispositional mindfulness is related to both the five factor model (FFM) and the reinforcement sensitivity theory (RST). However, previous research has examined those associations in isolation. We examined the unique effects of RST and the FFM on mindfulness in a sample 399 participants. Overall, we found the individual facets of mindfulness were differentially correlated with RST and FFM dimensions. Specifically, RST (BIS) and FFM (Neuroticism) dimensions that draw attention to external stimuli negatively correlated with mindfulness except for Observing. In contrast, FFM dimensions Openness and Conscientiousness correlated positively with mindfulness, suggesting a pattern where individuals routinely allocate attention to internal stimuli (being mindful) in order to explore (Openness) or to regulate these experiences (Conscientiousness). Our findings provide new insights into the underlying individual difference structure of being mindfulness and implies that mindfulness may not be a unitary construct. We suggest that future research should investigate mindfulness correlates at the facet level instead of the higher level of overall mindfulness.

Abstract

Psychology has become less WEIRD in recent years, marking progress towards becoming a truly global psychology. However, this increase in cultural diversity is not matched by greater attention to cultural biases in research. A significant challenge in culture-comparative research in psychology is that any comparisons are open to possible item bias and non-invariance. Unfortunately, many psychologists are not aware of problems and their implications, and do not know how to best test for invariance in their data. We provide a general introduction to invariance testing and a tutorial of three major classes of techniques that can be easily implemented in the free software and statistical language R. Specifically, we describe 1) confirmatory and multi-group confirmatory factor analysis, with extension to exploratory structural equation modelling, and multi-group alignment; 2) iterative hybrid logistic regression as well as 3) exploratory factor analysis and principal component analysis with Procrustes rotation. We pay specific attention to effect size measures of item biases and differential item function. Code in R is provided in the main text and online (see https://osf.io/agr5e/), and more extended code and a general introduction to R are available in the supplementary materials.

Abstract

Research on self-determination theory and clinical models such as acceptance and commitment therapy has shown that behaving in line with our values is key to maintaining healthy well-being. Combining work on values and experimental studies on moral hypocrisy and well-being, we experimentally tested how behaving incongruently with values affects well-being. We hypothesized that discrepancies between how one thinks one should have behaved and how one reported one did behave would be more detrimental to well-being when the behaviors were value-expressive and motivationally coherent compared to a control condition; greater perceived gaps between how participants feel they should have acted and how they report they did act would be associated with more negative well-being outcomes; the relationship between value manipulation and well-being would be mediated by perceived behavioral gap; and that personal values would interact with value manipulation to produce differential effects on well-being. One-hundred and fifty-eight first-year psychology students participated in an experiment designed to highlight discrepancies between how participants have behaved in accordance with a certain value and how they think they should have behaved, before reporting their well-being. As hypothesized, greater discrepancies between reported past behavior and how participants thought they should have behaved was associated with negative affect and decreased reports of positive well-being. We found no evidence for differential effects of manipulated value-expressive behaviors on well-being, or for our hypotheses that personal values and manipulated value-expressive behaviors interact. Nevertheless, value content mattered in terms of inducing perceived behavioral gaps. Our study suggests that perceived discrepancies between any value and reported past behavior can have a negative impact on some aspects of well-being. We discuss how the application of our methodology can be used in further studies to disentangle the value-behavior nexus.

Rituals, Repetitiveness and Cognitive Load

Karl, J. A. & Fischer, R. Human Nature

Abstract

A central hypothesis to account for the ubiquity of rituals across cultures is their supposed anxiolytic effects: rituals being maintained because they reduce existential anxiety and uncertainty. We aimed to test the anxiolytic effects of rituals by investigating two possible underlying mechanisms for it: cognitive load and repetitive movement. In our pre-registered experiment (osf.io/rsu9x), 180 undergraduates took part in either a stress or a control condition and were subsequently assigned to either control, cognitive load, undirected movement, a combination of undirected movement and cognitive load, or a ritualistic intervention. Using both repeated self-report measures and continuous physiological indicators of anxiety, we failed to find direct support for a cognitive suppression effect of anxiety through ritualistic behavior. Nevertheless, we found that induced stress increased participants’ subsequent repetitive behavior, which in turn reduced physiological arousal. This study provides novel evidence for plausible underlying effects of the proposed anxiolytic effect of rituals: repetitive behavior but not cognitive load may decrease physiological stress responses during ritual.
