Social groups and identities significantly influence mental health outcomes, yet their impact in resource-poor communities remains understudied. We explored the role of social group memberships and identities in shaping mental health experiences in two urban poor communities in Ghana. Data from 77 participants were analyzed thematically, revealing widespread engagement in social groups that provide access to both material and symbolic resources. However, these groups also serve as sources of tension and contribute to the stigmatization and marginalization of vulnerable members. Those affected include individuals with severe mental disorders, men experiencing depression, young men involved in substance abuse, family caregivers, migrant and tenant households, and otherwise healthy individuals with recurring psychosocial challenges. The groups exacerbate mental health challenges and restrict access to care among marginalized populations. The findings underscore the need for targeted interventions aimed at enhancing mental health support and reducing stigma in resource-poor settings.

Children\'s testimonial learning often occurs in epistemic collaborations with others. In this paper, we will discuss ways in which cultural learning emerges in social and interpersonal contexts, and is intrinsically supported and guided by children\'s collaborative capacities. Much work in cultural learning has focused on children\'s examination of speaker and model characteristics, but more recent research has investigated the interactive aspects of testimonial exchanges. We will review evidence that children (1) participate in the interpersonal commitments that are shared in testimonial transactions by way of direct address and epistemic buck passing, (2) participate in social groups that affect their selective learning in nuanced ways, and (3) may detect epistemic harms by listeners who refuse to believe sincere and accurate speakers. Implications for conceptualizing children\'s testimonial learning as an interactive mechanism of collaboration will be discussed.

We examine whether people conceptualize organized groups as having at least two parts: In addition to members (e.g., Alice), they also have social structures (i.e., roles and relations). If groups have members and social structures, then numerically distinct groups can have the same members if they differ in their structures. In Studies 1-4, participants numerically distinguished groups that had the same members when they had different structures. Participants numerically distinguished even when groups had the same function-the same people playing chess together Monday and Tuesday can be numerically distinct groups. In Study 4, we compare clubs to tables, and find that participants numerically distinguish tables by their structures too (i.e., the configuration of their parts) even when they have the same parts (which can be disassembled and then reassembled with ease). In Study 5, we find that participants rate groups as existing in space and time like concrete objects, suggesting that participants represent groups as at least partially concrete, such that groups have at least two parts (their structures and their members). Finally, in Study 6, we show that people will judge the same person as exemplary with respect to one group but condemnable with respect to another-even when those groups have the same members.

Previous research has indicated that children perceive social category members as having intrinsic obligations toward each other, which shape their expectations for social interactions. However, it is unclear whether teenagers (aged 13 to 15) and young adults (aged 19 to 21) continue to hold such beliefs, given their increased experience with group dynamics and external social rules. To explore this question, three experiments were conducted with a total of 360 participants (N = 180 for each age group). Experiment 1 examined negative social interactions using different methods in two sub-experiments, while Experiment 2 focused on positive social interactions to examine whether participants viewed social category members as intrinsically obligated to avoid harming each other and to offer assistance. Results revealed that teenagers evaluated within-group harm and non-help as unacceptable, regardless of external rules, whereas they viewed between-group harm and non-help as both acceptable and unacceptable, depending on the presence of external rules. Conversely, young adults considered both within-group and between-group harm/non-help as more acceptable if an external rule permitted such behavior. These findings suggest that teenagers believe that members of a social category are intrinsically obligated to help and not harm each other, whereas young adults believe that individual social interactions are constrained mainly by external rules. That is, teenagers hold stronger beliefs than young adults about intrinsic interpersonal obligations to group members. Thus, in-group moral obligations and external rules contribute differently to the evaluation and interpretation of social interactions at different developmental stages.

Although the ability to consider others\' visual perspectives to interpret ambiguous communication emerges during childhood, people sometimes fail to attend to their partner\'s perspective. Two studies investigated whether 4- to 6-year-olds show a \"closeness-communication bias\" in their consideration of a partner\'s perspective in a communication task. Participants played a game that required them to take their partner\'s visual perspective in order to interpret an ambiguous instruction. If children, like adults, perform worse when they overestimate the extent to which their perspective is aligned with that of a partner, then they should make more perspective-taking errors when interacting with a socially close partner compared with a more socially distant partner. In Study 1, social closeness was based on belonging to the same social group. In Study 2, social closeness was based on caregiving, a long-standing social relationship with a close kinship bond. Although social group membership did not affect children\'s consideration of their partner\'s perspective, children did make more perspective-taking errors when interacting with a close caregiver compared with a novel experimenter. These findings suggest that close personal relationships may be more likely to lead children to overestimate perspective alignment and hinder children\'s perspective-taking than shared social group membership, and they highlight important questions about the mechanisms underlying the effects of partner characteristics in perspective-taking tasks.

Residential location has been shown to significantly impact mental health, with individuals in rural communities experiencing poorer mental health compared to those in urban areas. However, the influence of an individual\'s social group on the relationship between residential location and mental health outcomes remains unclear. This study disaggregates the rural-urban binary and investigates how geography and social groupings interact to shape mental health outcomes. Merging data from PLACES and Claritas PRIZM, we conducted a hotspot analysis, generated bivariate choropleth maps, and applied multiscale geographically weighted regressions to examine the spatial distribution of mental health and social groupings. Our findings reveal that mental health is influenced by complex interactions, with social groups playing a critical role. Our study highlights that not all rural and urban areas are alike, and the extent to which social groups influence mental health outcomes varies within and across these areas. These results underscore the need for policies that are tailored to meet the unique mental health needs of individuals from different social groups in specific geographic locations to inform policy interventions that more effectively address mental health disparities across diverse communities.

Despite continued interest in mixed-species groups, we still lack a unified understanding of how ecological and social processes work across scales to influence group formation. Recent work has revealed ecological correlates of mixed-species group formation, but the mechanisms by which concomitant social dynamics produce these patterns, if at all, is unknown. Here, we use camera trap data for six mammalian grazer species in Serengeti National Park. Building on previous work, we found that ecological variables, and especially forage quality, influenced the chances of species overlap over small spatio-temporal scales (i.e. on the scales of several metres and hours). Migratory species (gazelle, wildebeest and zebra) were more likely to have heterospecific partners available in sites with higher forage quality, but the opposite was true for resident species (buffalo, hartebeest and topi). These findings illuminate the circumstances under which mixed-species group formation is even possible. Next, we found that greater heterospecific availability was associated with an increased probability of mixed-species group formation in gazelle, hartebeest, wildebeest and zebra, but ecological variables did not further shape these patterns. Overall, our results are consistent with a model whereby ecological and social drivers of group formation are species-specific and operate on different spatio-temporal scales. This article is part of the theme issue \'Mixed-species groups and aggregations: shaping ecological and behavioural patterns and processes\'.

Group membership is not always voluntary and can be imposed within a social context; moreover, those with power disproportionately shape group membership. We asked if children and adults view group membership as imposed by the powerful. We undertook four studies (465 children ages 4-9, 150 adults): Studies 1-2 used novel minimal groups; Study 3 used \'cool\' and \'uncool\'; Study 4 used novel ethnic groups. In the first three studies, children saw groups varying in power asserting that a non-categorized individual ought to belong to one of the operating groups in the context. Adults indicated that the declarations of the high-power group (and only the high-power group) made the individual a member of the declared group. Young children rejected that group membership could be imposed. In Study 4, children of all ages reasoned that the high-power group could decide membership for a consenting individual and impose clothing restrictions on a non-consenting individual; unlike adults, children of all ages did not reason the high-power group could impose group membership more frequently than chance. Taken together, adult participants consistently reasoned that group membership was imposed and disproportionately by those with power but children, more often than adults, reasoned that group membership was voluntary.

The French and the German national parliaments are dominated by highly educated, older, and mostly male politicians. There are growing calls for a more balanced political representation of different social groups. This paper seeks to inform this debate by conceptualizing and measuring representation gaps for women, people of immigrant origin, the working class, and younger age groups in France and Germany and by assessing the potential of deliberative participatory fora to ameliorate underrepresentation. Based on theories of deliberative and participatory democracy, it suggests three criteria these fora must fulfill to potentially balance underrepresentation (descriptive representation in composition, deliberative quality, and coupling to politics) and explores them empirically in four recent cases of deliberative participatory fora: the Grand Débat National and the Convention Citoyenne pour le Climat in France and the Bürgerrat Deutschlands Rolle in der Welt and the Bürgerrat Klima in Germany. We show that significant representation gaps exist for all groups studied. They have been narrowing for women and people of immigrant origin and remain most pronounced for class. Regarding institutional features, our cases fare relatively well in terms of balanced composition and deliberative quality, but the potential to balance representation gaps is seriously limited by a lack of coupling to the political system.
In der französischen Assemblée Nationale wie im deutschen Bundestag sind mehrheitlich höher gebildete, ältere und männliche Politiker*innen vertreten. Seit einiger Zeit wird eine ausgewogenere politische Repräsentation verschiedener sozialer Gruppen gefordert. Der Beitrag dieses Artikels zielt auf die Konzeptualisierung und Messung von Repräsentationslücken für Frauen, Menschen mit Migrationshintergrund, Arbeiter:innen und jüngere Menschen in Deutschland und Frankreich und versucht, das Potenzial deliberativ-partizipativer Verfahren zur Verringerung der Repräsentationslücken zu erfassen. Basierend auf Theorien deliberativer und partizipativer Demokratie werden drei institutionelle Kriterien vorgestellt, die diese Verfahren erfüllen müssen, um existierende Repräsentationslücken auszugleichen (deskriptive Repräsentation in der Zusammensetzung, deliberative Qualität und Verbindung zur Politik). Vier aktuelle deliberativ-partizipative Verfahren werden anschließend anhand der Kriterien untersucht: die Grand Débat National und die Convention Citoyenne pour le Climat in Frankreich sowie der Bürgerrat Deutschlands Rolle in der Welt und der Bürgerrat Klima in Deutschland. Wir zeigen, dass für alle analysierten Gruppen relevante Repräsentationslücken bestehen, die für Frauen und Menschen mit Migrationshintergrund im Untersuchungszeitraum kleiner werden, während sie für Arbeiter:innen am größten sind. Die institutionelle Gestaltung der untersuchten deliberativ-partizipativen Verfahren kann die repräsentative Zusammensetzung und Qualität der Deliberation fördern, das Potenzial zum Ausgleich von Repräsentationslücken wird aber durch die schlechte Verbindung zum politischen Entscheidungsprozess stark begrenzt.

Existing evidence suggests that the indigenous older population who live with their families and friends might experience lesser depressive symptoms due to better emotional support and well-being. The present study aimed to investigate the differentials in the prevalence of the major depressive disorder among tribal and non-tribal older populations in India and to explore the contribution of socio-demographic, health-related, and household factors in such disparities.
A cross-sectional study was conducted using data from the Longitudinal Aging Study in India (2017-18). The analytical sample included 30,637 older adults, among whom 5,025 and 25,612 belonged to the Scheduled Tribe (ST) and non-Scheduled Tribe (non-ST) social groups, respectively. Major depressive disorder assessed by the Composite International Diagnostic Interview short-form (CIDI-SF) scale was the outcome variable. Descriptive statistics, bivariate and multivariable regression and, decomposition analyses were conducted.
About 4.8% and 8.9% of older adults from the ST and non-ST social groups had major depression. For both tribal and non-tribal groups, older adults who were unmarried, dissatisfied with living arrangements, and those who faced lifetime discrimination were at increased risk of major depression. Findings from differences due to characteristics (E) revealed that if the regional differences were minimized, it would decrease the ST-non-ST gap in major depression by about 19.6%. Similarly, equal self-rated health status and chronic conditions among ST and non-ST groups would decrease the gap in major depression by almost 9.6% and 7.9%, respectively. Additionally, an equal status of Instrumental Activities of Daily Living (IADL) and Activities of Daily Living (ADL) among older adults would decrease the gap in major depression by about 3.8% and 3% respectively. Also, findings from differences due to coefficients (C) revealed that if older adults from the ST group had the same status of ADL as of older adults from the non-ST group, it would decrease the gap in major depression by about 11.8%.
The findings revealed a greater prevalence of major depression in older adults belonging to the non-ST group than the ST group. For both tribal and non-tribal groups, older adults who were unmarried, dissatisfied with living arrangements, and those who faced lifetime discrimination were at increased risk of major depression and these factors along with health-related variables contributed to significant ST-non-ST gap in depression, advantageous to tribal population; suggesting further research on the coping mechanisms of mental illnesses among indigenous population in India.
