In two experimental studies, we investigated mechanisms hypothesized to underpin two pervasive and interrelated phenomena: that certain forms of group movement and exercise lead to social bonding and that social bonding can lead to enhanced exercise performance. In Study 1, we manipulated synchrony and exercise intensity among rowers and found that, compared with low intensity exercise, moderate intensity exercise led to significantly higher levels of cooperation in an economic game; no effect of synchrony vs. non-synchrony was found. In Study 2, we investigated the effects of bonding on performance, using synchrony as a cue of existing supportive social bonds among participants. An elite, highly bonded team of rugby players participated in solo, synchronized, and non-synchronized warm-up sessions; participants' anaerobic performance significantly improved after the brief synchronous warm-up relative to the non-synchronous warm-up. The findings substantiate claims concerning the reciprocal links between group exercise and social bonding, and may help to explain the ubiquity of collective physical activity across cultural domains as varied as play, ritual, sport, and dance.

The World Health Organization urges countries to become more active in advocacy efforts to put mental health on governments' agendas. Health policy makers, planners and managers, advocacy groups, consumer and family organizations, through their different roles and actions, can move the mental health agenda forward. This paper outlines the importance of the advocacy movement, describes some of the roles and functions of the different groups and identifies some specific actions that can be adopted by Ministries of Health. The mental health advocacy movement has developed over the last 30 years as a means of combating stigma and prejudice against people with mental disorders and improving services. Consumer and family organizations and related NGOs have been able to influence governments on mental health policies and laws and educating the public on social integration of people with mental disorders. Governments can promote the development of a strong mental health advocacy sector without compromising this sector's independence. For instance, they can publish and distribute a directory of mental health advocacy groups, include them in their mental health activities and help fledgling groups become more established. There are also some advocacy functions that government officials can, and indeed, should perform themselves. Officials in the ministry of health can persuade officials in other branches of government to make mental health more of a priority, support advocacy activities with both general health workers and mental health workers and carry out public information campaigns about mental disorders and how to maintain good mental health. In conclusion, the World Health Organization believes mental health advocacy is one of the pillars to improve mental health care and the human rights of people with mental disorders. It is hoped that the recommendations in this article will help government officials and activists to strengthen national advocacy movements.

Social relationships and mental health are functionally integrated throughout the lifespan. Although recent laboratory‐based research has begun to reveal psychological pathways linking social interaction, interdependence, bonding and wellbeing, more evidence is needed to integrate and understand the potential significance of these accounts for real‐world events and interventions. In a questionnaire‐based, repeated measures design, we measured the wellbeing of 13‐ to 19‐year‐old participants (n = 226) in the Ten Tors Challenge (United Kingdom) 7–10 days before (T1) and after (T4) the event. Immediately before (T2) and after (T3) the event, we administered measures of team bonding, perceived and experienced interdependence, perceived and received support, physical pain and fatigue, and performance satisfaction. There was a significant increase in participants' wellbeing (pre‐to‐post event). Post‐event social bonding and performance satisfaction positively predicted the wellbeing increase. Bonding was, in turn, positively predicted by experienced interdependence, received support, pain and fatigue, and the sense of having done better as a team than expected. Results provide novel field‐based evidence on the associations between meaningful bonds of mutual reliance in a challenging team event and adolescent wellbeing. Team challenge events potentially offer effective contexts for forging social interactions, interdependencies, and bonds that can support mental and physical health.

Collective intelligence, an emergent phenomenon in which a composite system of multiple interacting agents performs at levels greater than the sum of its parts, has long compelled research efforts in social and behavioral sciences. To date, however, formal models of collective intelligence have lacked a plausible mathematical description of the relationship between local-scale interactions between autonomous sub-system components (individuals) and global-scale behavior of the composite system (the collective). In this paper we use the Active Inference Formulation (AIF), a framework for explaining the behavior of any non-equilibrium steady state system at any scale, to posit a minimal agent-based model that simulates the relationship between local individual-level interaction and collective intelligence. We explore the effects of providing baseline AIF agents (Model 1) with specific cognitive capabilities: Theory of Mind (Model 2), Goal Alignment (Model 3), and Theory of Mind with Goal Alignment (Model 4). These stepwise transitions in sophistication of cognitive ability are motivated by the types of advancements plausibly required for an AIF agent to persist and flourish in an environment populated by other highly autonomous AIF agents, and have also recently been shown to map naturally to canonical steps in human cognitive ability. Illustrative results show that stepwise cognitive transitions increase system performance by providing complementary mechanisms for alignment between agents’ local and global optima. Alignment emerges endogenously from the dynamics of interacting AIF agents themselves, rather than being imposed exogenously by incentives to agents’ behaviors (contra existing computational models of collective intelligence) or top-down priors for collective behavior (contra existing multiscale simulations of AIF). These results shed light on the types of generic information-theoretic patterns conducive to collective intelligence in human and other complex adaptive systems.
