The development of the Religious Health Interventions in Behavioural Science (RHIBS) Taxonomy: a scientific classification of religious practices in health.

The development and delivery of religiously integrated health interventions is increasing, however lack of nomenclature to specify the religious components presents barriers to replication, implementation, and evidence synthesis. We describe the development of the "Religious Health Interventions in Behavioural Sciences (RHIBS)" Taxonomy, the first scientific classification of religious intervention components to be used globally by chaplains, healthcare providers, and researchers interested in the scientific study of religion, spirituality, and health. We developed a taxonomy of empirically used religious intervention components in health, sought international cross-disciplinary consensus for definitions and tested its usability.

Preverbal infants expect agents exhibiting counterintuitive capacities to gain access to contested resources.

Claims to supernatural power have been used as a basis for authority in a wide range of societies, but little is known about developmental origins of the link between supernatural power and worldly authority. Here, we show that 12- to 16-month-old infants expect agents exhibiting counterintuitive capacities to win out in a two-way standoff over a contested resource. Infants watched two agents gain a reward using either physically intuitive or physically counterintuitive methods, the latter involving simple forms of levitation or teleportation.

Death anxiety and religion.

This review summarises research on the relationship between death anxiety and religiosity. The fear of death is commonly hypothesized as a motivation for religious belief. From a Terror Management Theory perspective, religious beliefs are especially attractive because they offer both literal and symbolic immortality in the form of afterlife beliefs and belonging in venerable systems of value respectively.

Traumatic life experiences and religiosity in eight countries.

We present two datasets from a project about the relationship between traumatic life experiences and religiosity. These include data from 1,754 individuals in the United States (n = 322), Brazil (n = 205), China (n = 202), India (n = 205), Indonesia (n = 205), Russia (n = 205), Thailand (n = 205), and Turkey (n = 205). Surveys were consistent across samples: they include measures of traumatic life experiences, negative affective traits, existential security, life satisfaction, death anxiety, and various religious beliefs, attitudes, and behaviours.

Devoted fans release more cortisol when watching live soccer matches.

Why do some sports fans experience intense emotions when watching live matches? Identity fusion is a strong form of group alignment in which personal and group identities are activated synergistically to produce a visceral sense of 'oneness' with one's team. Here we examine the role of fusion (using a three-item state measure with high internal validity) in elevating salivary cortisol levels while watching football (n = 41). Our evidence was gathered at field laboratories during the 2014 sFIFA World Cup in Natal, Brazil, with live screenings of two Brazilian victories (Colombia, 2-1; Chile, 1-1 with penalties), and the historic semi-final loss to Germany (1-7).

Beyond Buddhism and animism: A psychometric test of the structure of Burmese Theravada Buddhism.

Anthropologists and religious scholars have long debated the relationship between doctrinal Theravada Buddhism, so-called 'animism', and other folk practices in southeast Asian societies. A variety of models of this relationship have been proposed on the basis of ethnographic evidence. We provide the first psychometric and quantitative evaluation of these competing models, using a new scale developed for this purpose, the Burmese Buddhist Religiosity Scale.

Positive experiences of high arousal martial arts rituals are linked to identity fusion and costly pro-group actions.

A cross-sectional study was conducted with 605 practitioners of Brazilian Jiu Jitsu (BJJ) to test the hypothesis that high arousal rituals promote social cohesion, primarily through identity fusion. BJJ promotion rituals are rare, highly emotional ritual events that often feature gruelling belt-whipping gauntlets. We used the variation in such experiences to examine whether more gruelling rituals were associated with identity fusion and pro-group behaviour.

Death anxiety, exposure to death, mortuary preferences, and religiosity in five countries.

We present three datasets from a project about the relationship between death anxiety and religiosity. These include data from 1,838 individuals in the United States (n = 813), Brazil (n = 800), Russia (n = 800), the Philippines (n = 200), South Korea (n = 200), and Japan (n = 219). Measures were largely consistent across samples: they include measures of death anxiety, experience of and exposure to death, religious belief, religious behaviour, religious experience, and demographic information.

Death salience moderates the effect of trauma on religiosity.

Objective: Previous research has shown contradictory evidence for the relationship between religiosity and trauma; exposure to traumatic life events has been associated with both increases and decreases in religiosity over time. On the basis of a long theoretical tradition of linking death and religious belief and recent empirical evidence that thoughts of death may increase religiosity, we tested whether one determinant of trauma's influence on religion is the degree to which it makes death salient.

Method: Using longitudinal data from the Dunedin Multidisciplinary Health and Development Study, a unique population-representative birth cohort, we tested whether the relationship between trauma and religiosity depends on whether the trauma involves death.

Groups and Emotional Arousal Mediate Neural Synchrony and Perceived Ritual Efficacy.

We present the first neurophysiological signatures showing distinctive effects of group social context and emotional arousal on cultural perceptions, such as the efficacy of religious rituals. Using a novel protocol, EEG data were simultaneously recorded from ethnic Chinese religious believers in group and individual settings as they rated the perceived efficacy of low, medium, and high arousal spirit-medium rituals presented as video clips. Neural oscillatory patterns were then analyzed for these perceptual judgements, categorized as low, medium, and high efficacy.

Relational mobility predicts social behaviors in 39 countries and is tied to historical farming and threat.

Biologists and social scientists have long tried to understand why some societies have more fluid and open interpersonal relationships and how those differences influence culture. This study measures relational mobility, a socioecological variable quantifying voluntary (high relational mobility) vs. fixed (low relational mobility) interpersonal relationships.

Synchrony and Physiological Arousal Increase Cohesion and Cooperation in Large Naturalistic Groups.

Separate research streams have identified synchrony and arousal as two factors that might contribute to the effects of human rituals on social cohesion and cooperation. But no research has manipulated these variables in the field to investigate their causal - and potentially interactive - effects on prosocial behaviour. Across four experimental sessions involving large samples of strangers, we manipulated the synchronous and physiologically arousing affordances of a group marching task within a sports stadium.

The evolution of the shaman's cultural toolkit.

A complete picture of shamanism's cultural evolution requires an understanding of how the professionalization of shamanism affects the distribution of knowledge within societies. We suggest that limiting knowledge to fewer people could impede the accumulation of functional knowledge within shamanism. On this basis, we make further predictions about how the domain of shamanism could change and collapse.

What Is the Molecular Signature of Mind-Body Interventions? A Systematic Review of Gene Expression Changes Induced by Meditation and Related Practices.

There is considerable evidence for the effectiveness of mind-body interventions (MBIs) in improving mental and physical health, but the molecular mechanisms of these benefits remain poorly understood. One hypothesis is that MBIs reverse expression of genes involved in inflammatory reactions that are induced by stress. This systematic review was conducted to examine changes in gene expression that occur after MBIs and to explore how these molecular changes are related to health.

The evolution of extreme cooperation via shared dysphoric experiences.

Willingness to lay down one's life for a group of non-kin, well documented historically and ethnographically, represents an evolutionary puzzle. Building on research in social psychology, we develop a mathematical model showing how conditioning cooperation on previous shared experience can allow individually costly pro-group behavior to evolve. The model generates a series of predictions that we then test empirically in a range of special sample populations (including military veterans, college fraternity/sorority members, football fans, martial arts practitioners, and twins).

Rituals Improve Children's Ability to Delay Gratification.

To be accepted into social groups, individuals must internalize and reproduce appropriate group conventions, such as rituals. The copying of such rigid and socially stipulated behavioral sequences places heavy demands on executive function. Given previous research showing that challenging executive functioning improves it, it was hypothesized that engagement in ritualistic behaviors improves children's executive functioning, in turn improving their ability to delay gratification.

Measuring Cross-Cultural Supernatural Beliefs with Self- and Peer-Reports.

Despite claims about the universality of religious belief, whether religiosity scales have the same meaning when administered inter-subjectively-or translated and applied cross-culturally-is currently unknown. Using the recent "Supernatural Belief Scale" (SBS), we present a primer on how to verify the strong assumptions of measurement invariance required in research on religion. A comparison of two independent samples, Croatians and New Zealanders, showed that, despite a sophisticated psychometric model, measurement invariance could be demonstrated for the SBS except for two noninvariant intercepts.

Collective synchrony increases prosociality towards non-performers and outgroup members.

Previous research has found that behavioural synchrony between people leads to greater prosocial tendencies towards co-performers. In this study, we investigated the scope of this prosocial effect: does it extend beyond the performance group to an extended ingroup (extended parochial prosociality) or even to other people in general (generalized prosociality)? Participants performed a simple rhythmic movement either in time (synchrony condition) or out of time (asynchrony condition) with each other. Before and during the rhythmic movement, participants were exposed to a prime that made salient an extended ingroup identity.

Incipient Social Groups: An Analysis via In-Vivo Behavioral Tracking.

Social psychology is fundamentally the study of individuals in groups, yet there remain basic unanswered questions about group formation, structure, and change. We argue that the problem is methodological. Until recently, there was no way to track who was interacting with whom with anything approximating valid resolution and scale.

Shared Negative Experiences Lead to Identity Fusion via Personal Reflection.

Across three studies, we examined the role of shared negative experiences in the formation of strong social bonds--identity fusion--previously associated with individuals' willingness to self-sacrifice for the sake of their groups. Studies 1 and 2 were correlational studies conducted on two different populations. In Study 1, we found that the extent to which Northern Irish Republicans and Unionists experienced shared negative experiences was associated with levels of identity fusion, and that this relationship was mediated by their reflection on these experiences.
