Поэтапное сокращение сотрудничества между людьми.

Сотрудничество между людьми носит динамичный характер и зачастую сокращается даже при наличии благоприятных условий conditions1-4. Многие из существующих теорий объясняют уменьшение масштабов сотрудничества с точки зрения стратегического поведения или обучения, сформулированного как свидетельство рационального поведения или продвижения в направлении rationality5-9. Здесь мы показываем, что одним из ключевых источников долгосрочного спада являются отклонения от рационального поведения, которые систематически меняются с течением времени. Мы анализируем естественную социальную дилемму на местах,

Evaluating a Community-partnered Approach to Address Locally Relevant Determinants of Cancer Screening in New York City.

BACKGROUND: New York City (NYC) Cancer Outreach Network in Neighborhoods for Equity and Community Translation (CONNECT) aims to address determinants of cancer screening and access disparities in low-income NYC neighborhoods with high cancer burden. OBJECTIVES: NYC CONNECT community partners formed neighborhood action councils (NACs) and engaged in mixed-method formative research and an iterative consensus-building process to co-identify structural and social determinants of cancer screening. The NACs co-developed with health and academic partners community-level strategies to address structur

Structural stigma and intersectional inequality in schizophrenia: A systematic review and qualitative meta-synthesis.

Schizophrenia is unequally distributed across social hierarchies and is associated with stratified pathways of care, coercion, and recovery. Although stigma has been widely studied, existing scholarship has predominantly emphasized interpersonal attitudes and individual behavior, leaving structural stigma embedded in policy regimes, institutional practices, and epistemic hierarchies insufficiently synthesized. Guided by PRISMA 2020, this systematic review and qualitative meta-synthesis examined 29 sources, comprising 17 core empirical studies and 12 contextual or theoretical sources, addressin

The impact of social support, emotion regulation, depression, and psychache on suicide risk among individuals with alcohol use disorder.

BACKGROUND: Individuals with Alcohol Use Disorder (AUD) exhibit a significantly heightened risk of suicide, yet the contributing explanatory mechanisms remain insufficiently understood. This study aimed to examine a structural model linking perceived social support, emotion regulation, depressive symptoms, psychache, and suicide risk, and to assess whether clinical status (AUD vs. healthy controls, HC) moderated these links. METHODS: A cross-sectional sample of 257 participants (AUD: n = 133; HC: n = 124) completed validated self-report measures. Structural Equation Modelling (SEM) was applie

Predictive models for perceived convenience of accessing outdoor activities among elderly with physical disabilities in rural China.

BACKGROUND: The elderly, especially those with physical disabilities, often encounter barriers that prevent them from accessing outdoor activities. Their perceptions of the convenience of accessing outdoor activities may be influenced by various factors including their health, the social context, and/or planned behavior. This study aimed to develop predictive models that identify the principal determinants of perceived convenience among this demographic, and it also examined the disparities observed between genders. METHODS: This was a cross-sectional survey of 1216 community-dwelling older p

The extended neural architecture of human attachment: An fMRI coordinate-based meta-analysis of affiliative studies.

Functional imaging studies and clinical evidence indicate that cortical areas relevant to social cognition are closely integrated with evolutionarily conserved basal forebrain structures and neighboring regions, enabling human attachment and affiliative emotions. The neural circuitry of human affiliation is continually being unraveled as functional magnetic resonance imaging (fMRI) becomes increasingly prevalent, with studies examining human brain responses to various attachment figures. However, previous fMRI meta-analyses on affiliative stimuli have encountered challenges, such as low statis

[The Fear of Negative Evaluation scale (FNE): psychometric properties of the French version].

BACKGROUND: The Fear of Negative Evaluation scale (FNE: Watson and Friend, 1969) is the measure most commonly used to determine the degree to which people experience apprehension at the prospect of being negatively evaluated. Although the development of the FNE preceded the inclusion of social anxiety disorder (or social phobia) in the diagnostic classification system, it is widely used as a measure of cognitive symptoms because the feature tapped by this measure is at the core of recent cognitive models of social-anxiety. According to these models, socially anxious individuals divide their at

Perceived inclusive growth as lived experience: Development and initial validation of an individual-level measure.

Inclusive growth is typically assessed through macro- and meso-level indicators, offering limited evidence on how individuals evaluate the accessibility and fairness of development-related opportunities, services, protections, and institutions. This study develops and initially validates an individual-level measure of perceived inclusive-growth progress in Pakistan. An exploratory sequential mixed-methods design integrated literature-derived content with qualitative evidence from eight focus groups involving 64 participants and four individual interviews. Following expert assessment and pilot

Thalamocortical orchestration of human theory of mind.

Reasoning about others' thoughts or beliefs is central to human social behavior. This ability, known as theory of mind (ToM), has been primarily attributed to cortical regions of the default network (DN). However, whether and how subcortical structures, particularly the thalamus, contribute to this high-level computation remains unknown. Here, we investigated human thalamocortical dynamics during a naturalistic ToM movie watching condition, taking a rare dual-modality approach by combining high-field 7T fMRI and intracranial stereoelectroencephalography (sEEG). Across both modalities, ToM even

The suspension of dis/belief (Sd/B) chronicity scale: Psychometric development and validation.

Suspension of dis/belief (Sd/B) refers to temporarily withholding truth evaluation to engage with fictional, hypothetical, or counter-attitudinal information. Although Sd/B is widely invoked across media, education, and social cognition, research has relied on context-bound measures tied to specific media or settings, such as film, gaming, virtual reality, or simulation-based learning. We developed and validated a brief self-report instrument assessing how frequently individuals report engaging in behaviors that require Sd/B (the Sd/B Chronicity Scale). Across three studies in Portugal and the

Validation of the Farsi version of the cyberloafing scale in Iranian university students.

BACKGROUND: Despite its relevance in academic settings, the psychometric properties of the Farsi Cyberloafing Scale (CLS) remain underexplored. This study evaluated its factorial structure, measurement invariance, and convergent validity. METHODS: A cross-sectional design was employed. The statistical population consisted of all students aged 18 to 32 who were active in various universities in Tabriz. From this population, 389 individuals were selected as the research sample through convenience sampling. Data were collected using Cyberloafing Scale, Social Media Addiction Scale, and Ruminatio

Social network isolation and cohesion and their association with HIV clustering among Black and Latino sexual minority men: implications for public health strategy.

Evidence shows social networks shape HIV transmission by influencing partner access, behaviors, and health. Molecular cluster analysis offers insight into recent transmission, yet little is known about how network isolation or cohesion relate to clustering. This study examined social networks to identify factors associated with molecular HIV clustering. Data are from a cross-sectional study among Black and Latinx sexual minority men collected 2022-24 in Raleigh-Durham, NC. Participants nominated up to 20 friends and 20 sex partners. Other survey measures included age, gender, and socioeconomic

People Who Identify with All of Humanity Make Less of a Moral Distinction Between Close and Distant People.

In the era of promoting the concept of a "Community with a Shared Future for Mankind," understanding the psychological mechanisms underlying relational morality in Chinese culture holds important theoretical and practical value, particularly given its hierarchical structure of moral obligations. Across four studies, this research innovatively proposes a calculation method for moral differential mode to deeply explore how identification with all humanity (IWAH) influences Chinese people's moral differential mode. Study 1 used questionnaires to preliminarily explore the differential characterist

Brain structure in triple X syndrome: regional gray matter volume and cortical thickness in adult women with 47,XXX karyotype.

BACKGROUND: Changes in the brain structure of women with Triple X syndrome (karyotype 47,XXX) have been described in a few studies to date, including reduced total brain volume and regional reductions in gray substance in cortical and subcortical areas. However, the empirical evidence from adults is very limited and group comparison on a voxel-wise basis for gray matter volume and cortical thickness is still missing. METHODS: Using voxel-based morphometry (VBM) and surface-based morphometry (SBM), we investigated regional gray matter changes in a sample of n = 20 adult women (aged 18-49 years

Students' Perspectives on Fostering a Sense of School Belonging in Greece: Moving Beyond COVID-19.

BACKGROUND: Students' sense of school belonging is important for mental health, physical health, and academic performance. However, some students do not feel as though they belong in their schools. This study investigated Greek secondary school students' perspectives on practices that enhanced their sense of belonging during the COVID-19 pandemic. METHOD: An online survey used open-ended questions to explore the views of 226 Greek secondary school students. RESULTS: Thematic analysis identified four teacher-level practice themes: communication and understanding, respect and inclusion, suppor

Critical Success Factors for Intersectoral Collaboration: Homelessness and COVID-19 - Case Studies and Learnings from an Australian City.

INTRODUCTION: The COVID-19 pandemic disproportionally impacted people experiencing homelessness, including people sleeping rough, people in temporary accommodation and those living in boarding houses. This paper reports on intersectoral responses across six health and social care agencies in Inner Sydney, New South Wales, Australia. Prior to the pandemic the six agencies had established an Intersectoral Homelessness Health Strategy (IHHS), in recognition of the need for intersectoral collaboration to address the complex health needs of people experiencing homelessness.
