The cultural logic of 'honour' is frequently studied in relation to conflict, but its role in competition and cooperation remains underexplored. The current study investigates how perceived normative and personally endorsed honour values predict competition and cooperation behaviours. In an online experiment testing preregistered hypotheses, 3,371 participants from 13 societies made incentivized competition decisions in a contest game and cooperation decisions for coordination in a step-level public goods game. Perceived normative honour values were associated with greater competition and greater cooperation at both societal and individual levels. Personally endorsing values tied to defence of family reputation was associated with greater coordinative efforts, whereas endorsing self-promotion and retaliation was associated with weaker engagement in coordination. These findings highlight the role of honour as a cultural logic (in its different forms) in shaping competition and cooperation across societies.","PeriodicalId":19074,"journal":{"name":"Nature Human Behaviour","volume":"42 1","pages":""},"PeriodicalIF":29.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, in this nationwide register-based study in Sweden (2,196,276 pregnancies), we defined the year before conception, pregnancy and the year after birth and estimated week-specific incidence rate ratios (IRRs). We identified 7,469 (1.39 per 1,000 person-years) suicide attempts among mothers and 8,338 (1.62 per 1,000 person-years) among fathers. Compared with the corresponding week in the preconception period, mothers had a lower risk of suicide attempt during and after pregnancy (with the lowest IRR of 0.14 (0.11-0.17) at first week postpartum); fathers' risk of suicide attempt remained largely stable before childbirth, but a lower risk was observed during the first 10 postpartum weeks (IRRs ranging from 0.69 (0.58-0.81) to 0.91 (0.84-0.99)), followed by a higher risk in the later postpartum period (IRRs ranging from 1.10 (1.01-1.21) to 1.72 (1.33-2.24)). Compared with fathers, mothers had a lower risk of suicide attempt during and after pregnancy (for example, IRR of 0.22 (0.18-0.28) at first week postpartum). Compared with the general population, the sex difference of suicide attempt is reversed during and after pregnancy, suggesting pregnancy or childbirth may have a more pronounced association with suicide attempt among mothers than fathers.","PeriodicalId":19074,"journal":{"name":"Nature Human Behaviour","volume":"3 1","pages":""},"PeriodicalIF":29.9,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Economic games, incorporated with network science, are frequently used to examine social behaviour. Traditionally, such game models and experiments artificially limit players' abilities to take varied actions towards distinct social neighbours, thereby constraining their social networking agency. Here we designed an experimental paradigm that alters this agency and applied it to the prisoner's dilemma (N = 735), trust game (N = 735) and ultimatum game (N = 735) to investigate cooperation, trust and fairness. Granting participants greater network agency led to more prosocial behaviour across all three economic games, resulting in higher wealth and lower inequality compared with control groups. These findings suggest that incorporating social networking agency into experimental designs better captures the prosocial potential of human behaviour.","PeriodicalId":19074,"journal":{"name":"Nature Human Behaviour","volume":"1 1","pages":""},"PeriodicalIF":29.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145133919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

We conducted a pre-registered systematic review and meta-analysis of randomized controlled trials using social norms messaging in developed countries targeted at changing health behaviours among 16+-year-olds to evaluate their effectiveness. Relevant studies were identified through searches in PsycINFO, Medline, Embase, Web of Science, TRIP, Cochrane and grey literature sources. Risk of bias was assessed independently by two reviewers using the Cochrane RoB 2 tool. A random-effects meta-analysis standardized effect sizes to Cohen's d, assessed heterogeneity with I² and applied robust Bayesian meta-analysis to adjust for publication bias. Searches resulted in 89 studies (n = 85,759), which exhibited a small effect of social norms messaging on health behaviours (Cohen's d = 0.1, 95% confidence interval (CI) [0.09, 0.19], P < 0.001). However, this effect disappeared after controlling for publication bias. We conducted moderator analyses, finding no significant differences from the overall effect for different types of social norms message, delivery modalities, health domains or target populations. The review is limited by the lack of studies assessing whether normative information changed participant perceptions, inconsistent use of manipulation checks, and high heterogeneity across studies in terms of target behaviour, population and intervention delivery, affecting the robustness of conclusions. Our analysis suggests that when appropriately controlling for publication bias, social norms messages are not effective at improving health behaviours. Thus, future attempts at improving public health should focus on alternative approaches.","PeriodicalId":19074,"journal":{"name":"Nature Human Behaviour","volume":"11 1","pages":""},"PeriodicalIF":29.9,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145117042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
