This article explores the implications of the social brain and the endorphin-based bonding mechanism that underpins it for the evolution of religion. I argue that religion evolved as one of the behavioural mechanisms designed to facilitate community bonding when humans first evolved the larger social groups of ~150 that now characterise our species. This is not a matter of facilitating cooperation, but of engineering social cohesion – a very different problem. Analysis of the size of C19th utopian communities suggests (...) that a religious basis both allowed larger groups to form and greatly enhanced their longevity. I suggest that religion evolved in two stages: an early immersive form with no formal structure based on trance-dancing (a form still evident in the rituals and practices of many hunter-gatherers) and a later form which had more formal structures and gave rise to our modern doctrinal religions. I argue that the modern doctrinal religions did not replace ancestral immersive religions but rather that the doctrinal component was overlaid on the ancient immersive form, thereby giving rise to the mystical stance that underlies all world religions. I suggest that it is this mystical stance that causes the constant upwelling of cults and sects within world religions. (shrink)

Depression experienced by older adults is proving an increasing global health burden, with rates generally 7% and as high as 27% in the USA. This is likely to significantly increase in coming years as the number and proportion of older adults in the population rises all around the world. Therefore, it is imperative that the effectiveness of approaches to the prevention and treatment of depression are understood. Creative arts interventions, including art, dance movement, drama and music modalities, are utilised internationally (...) to target depression and depressive symptoms in older adults. This includes interventions led by trained arts therapists as well as other health and arts professionals. However, to date there has not been a systematic review that reports effects and examines the processes (why) and mechanisms (how) of creative arts interventions are used to address depression in this older age group. This systematic review of studies on creative arts interventions for older adults experiencing depression examined: outcomes of four creative arts modalities (art, dance movement, drama, and music); with particular attention paid to processes documented as contributing to change in each modality; and mechanisms considered to result from these processes. Our analysis of 75 articles (17 art, 13 dance, 4 drama and 41 music) indicates mostly significant quantitative or positive qualitative findings, particularly for interventions led by creative arts therapists. Mechanisms of change gleaned from the studies that were common across modalities include physical (e.g. increased muscle strength; neurochemical effects, such as endorphin release), intra-personal (e.g. enhanced self-concept, strengthened agency and mastery; processing and communication of emotions), cultural (e.g. creative expression, aesthetic pleasure), cognitive (e.g. stimulation of memory) and social (e.g. increased social skills and connection), that were all considered to contribute to reduced depression and symptoms. Recommendations for future research include a stronger focus on testing of processes and mechanisms. (shrink)

Several models of the evolution of religion claim that ritual creates “religion” and gives it a positive evolutionary role. Robert Bellah suggests that the evolutionary roots of ritual lay in the play of animals. For Homo sapiens, Bellah argues, rituals generate a world of experience different from the world of everyday life, and that different world of experience is the foundation of later religious developments. Robin Dunbar points to trance dancing as the original religious behavior. Trance dancing both alters ordinary (...) consciousness and generates trance experiences that will give rise to religious concepts and also, through the production of endorphins, bonds people into tight-knit social groups whose social bonding gives them a survival advantage. The role of ritual in social bonding has been well established through the research on the production of endorphins by synchronized activity and the role of endorphins in social bonding. The role of ritual in generating religious experience has been much less developed. Drawing on the extensive research on the ways in which bodily activity can impact and transform our sensory and cognitive processes, and the ways in which sensory and cognitive processes are neurologically connected with somatic processes, this article will propose one neuropsychological model of how ritual activity might give rise to religion. Starting from bodily activity means that here religion will be understood more as a set of practices and less as a set of beliefs. Theological implications of this model will be discussed. (shrink)

Social grooming is an important element of social life in terrestrial primates, inducing the putative benefits of β-endorphin stimulation and group harmony and cohesion. Implicit in many analyses of grooming (e.g. biological markets) are the assumptions of costs and benefits to grooming behaviour. Here, in a review of literature, we investigate the proximate costs and benefits of grooming, as a potentially useful explanatory substrate to the well-documented ultimate (functional) explanations. We find that the hedonic benefits of grooming are well (...) documented. However, we did not find convincing evidence for costs. If proximate costs do exist, they might consist of energetic, cognitive, opportunity costs, or some combination of all of these. Nonetheless, there remains the possibility that grooming costs are negligible, or even that the provision of allogrooming is rewarding in itself. We suggest empirical research to resolve this issue.

We can share experiences with a person online, but the experiences seem thin when compared with face-to-face experiences. Online adventures (social networking, gaming) can certainly strengthen friendship bonds that were forged in more embodied interactions, but can they create those bonds? The kind of presence required for deep friendship does not seem cultivated in many online interactions. Presence in friendship requires “being with” and “doing for” (sacrifice). The forms of “being with” and “doing for” on social networking sites (or even (...) in interactive gaming) seem trivial because the stakes are very low. More important, the “shared space” of digital life is disembodied space. We cannot really touch one another, smell one another, detect facial expressions or moods, and so on. Real bonding is more biological than psychological and requires physical contact. The emotional entanglement of real friendship produces oxytocin and endorphins in the brains and bodies of friends — cementing them together in ways that are more profound than other relationships. -/- It is possible that virtual reality and augmented reality technology will soon be able to generate such friendship-forming experiences. Having embodied adventures with another person — even in a V.R. suit — is more likely to trigger the deeper oxytocin-based bonding. Current social networking, however, seems to privilege the shallow triggers of the brain’s reward system (dopamine squirts in the ventral tegumental area). (shrink)

A social network is a web that integrates multiple levels of interindividual social relationships and has direct associations with an individual’s health and well-being. Previous research has mainly focused on how brain and social network structures act on each other and on how the brain supports the spread of ideas and behaviors within social networks. The structure of the social network is correlated with activity in the amygdala, which links decoding and interpreting social signals and social values. The structure also (...) relies on the mentalizing network, which is central to an individual’s ability to infer the mental states of others. Network functional properties depend on multilayer brain-social networks, indicating that information transmission is supported by the default mode system, the valuation system, and the mentalizing system. From the perspective of neuroendocrinology, overwhelming evidence shows that variations in oxytocin, β-endorphin and dopamine receptor genes, including oxytocin receptor, mu opioid receptor 1 and dopamine receptor 2, predict an individual’s social network structure, whereas oxytocin also contributes to improved transmission of emotional and behavioral information from person to person. Overall, previous studies have comprehensively revealed the effects of the brain, endocrine system, and genes on social networks. Future studies are required to determine the effects of cognitive abilities, such as memory, on social networks, the characteristics and neural mechanism of social networks in mental illness and how social networks change over time through the use of longitudinal methods.

In lieu of an abstract, here is a brief excerpt of the content:Folk Psychology and the Psychological Background of Scientific ReasoningHarald Walach (bio)Keywordstheory of psychology, theory of science, psychology of science, mind-body problem, folk psychology, scientific world viewSome protagonists of science who are still married to a positivist model of how science functions see science as the pure pursuit of knowledge, free of any preconceptions, free of any personal interest, yielding clear and ideally everlasting truths beckoning humanity over from a (...) superstition ridden dark age of beliefs and would-be knowledge toward the dawn of rational insights that allow for the bettering of mankind’s problems. Scientists have followed such an implicit model since Francis Bacon’s Novum Organon, and the most recent reverberations we hear in popular science books like The God Delusion by Dawkins (2006) or in more scientific ones on how an eliminative materialist account of mental events such as Patricia Churchland’s might work (Churchland 1986). Here, it is explicitly stated that our folk-psychological accounts such as “I love Emma,” or “I have a nasty back ache” is nothing but sloppy speaking and will soon be replaced by a more scientific account, once we know the interior workings of our brains, such as “Neuron assembly xyz in my nucleus abc in brain areas efg is firing” or “Fast A1 fibers are transmitting stimuli from my lumbar region to the brain, where they override endorphin- and enkephalin-mediated inhibiting pathways, enabling the pain network to go crazy.” It has been more than twenty years now since the publication of that somewhat futuristic account, and a whole decade of the brain and countless papers have taught us that we are very far, in fact light years away, from such knowledge as eliminative and even less eliminative materialists would have us gained by now, or in another twenty years from now.Folk psychology is well and alive, and even more vital than ever, it seems. People go about having their beliefs and ideas about God, the mind, the soul, the world, and human beings in general just as well, eliminative materialists and neuroscience notwithstanding. The data presented by Fahrenberg speak a clear language: Students of different disciplines, but most prominently psychology students, adhere mostly to a dualist—ontological or methodological—world view that allows for some substantiality of consciousness. They suppose that some transcendent reality is active and about, they assume that paranormal events such as spiritual and distant healing can [End Page 209] happen, that telepathy is an option, to name but the more prominent statements to be gleaned by Fahrenberg’s tables.Sure, these are students at the beginning of their career, as they come from school, some of them in their second year, some of them mature after having done some other training. They have had contact with the scientific world view mostly through their schooling and private reading, and, of course, through our folk culture. It would be extremely interesting to see a longitudinal study, surveying the same students after four years of studies. Will they then be more conformist with the mainstream scientific notion? Will they then have changed their initial belief systems? Will they have integrated and absorbed the knowledge they were taught into their private lives and worldviews, or will they have kept them apart from each other? We do not have the answer to these questions, and surely, a next step would be to follow a cohort of students, albeit small, through their journey as they progress.Meanwhile, we can all take ourselves as an example to follow this thought along as a gedan-kenexperiment. Did we allow the knowledge we absorbed from studying to permeate our whole private life? How did we deal with any cognitive dissonance arising from information coming out of our studies conflicting with our private belief systems? Did we throw away our personal beliefs or did we organize our lives in two compartments, one for our private life, and one for our scientific knowledge?Fahrenberg’s data are unique in the sense that nobody bothers about folk psychology, and these data are the only ones that actually tap into the belief systems of those that will become scientists, teachers, therapists and trainers...

Meeting humans is an everyday experience for most companion dogs, and their behavior in these situations and its genetic background is of major interest. Previous research in our laboratory reported that in German shepherd dogs the lack of G allele, and in Border collies the lack of A allele, of the oxytocin receptor gene (OXTR) 19208A/G single nucleotide polymorphism (SNP) was linked to increased friendliness, which suggests that although broad traits are affected by genetic variability, the specific links between alleles (...) and behavioural variables might be breed-specific. In the current study, we found that Siberian huskies with the A allele approached a friendly unfamiliar woman less frequently in a greeting test, which indicates that certain polymorphisms are related to human directed behaviour, but that the relationship patterns between polymorphisms and behavioural phenotypes differ between populations. This finding was further supported by our next investigation. According to primate studies, endogenous opioid peptide (e.g. endorphins) receptor genes have also been implicated in social relationships. Therefore, we examined the rs21912990 of the OPRM1 gene. Firstly, we found that the allele frequencies of Siberian huskies and gray wolves were similar, but differed from that of Border collies and German shepherd dogs, which might reflect their genetic relationship. Secondly, we detected significant associations between the OPRM1 SNP and greeting behaviour among German shepherd dogs and a trend in Border collies, but we could not detect an association in Siberian huskies. Although our results with OXTR and OPRM1 gene variants should be regarded as preliminary due to the relatively low sample size, they suggest that (1) OXTR and OPRM1 gene variants in dogs affect human-directed social behaviour and (2) their effects differ between breeds.

The placebo drug reactions from controlled trials were studied for the first time systematically for efficacy and the safety in drug data pooled from randomized, placebo-controlled, multicentre studies. Results: The efficacy of placebo on clinical symptoms and outcome varied between the therapeutic indications. However, no placebo effects on laboratory values, as e.g. blood glucose or Hb1c in diabetics, were noted. The frequency and type of placebo-induced adverse reactions also varied between indication groups. The placebo side effect profile was largely similar (...) to the side effect profile of the active treatment. The mechanisms of placebo effects are manyfold and varied (e.g. endorphin release, conditioning), much lacks explanation. Conclusion: Since the prescription of non-evidence based medicines (= pseudoplacebos) may clearly also result in serious adverse effects, such practice may not only be non-beneficial but may even be harmful. In clinical research, the judicious use of placebo remains essential to establish the efficacy and safety, safeguarding that patients receiving placebo will not be subject to harm and are fully informed.

She found a little bottle on it, and round the neck of the bottle was a paper label, with the words “DRINK ME” beautifully printed on it in large letters. It was all very well to say “Drink me,” but (...) the wise little Alice was not going to do that in a hurry. “No, I’ll look first,” she said, “and see whether it’s marked ‘poison’ or not.” However, the bottle was not marked “poison,” so Alice ventured to taste it, and finding it very nice, (it had, in fact, a sort of mixed flavour of cherry-tart, custard, pine-apple, roast turkey, toffee, and hot buttered toast), she very soon finished it off. “What a curious feeling!” said Alice. —Lewis Carroll, Alice’s Adventures in Wonderland (1865) যে ব্যামোর দেখবেন সাতান্ন রকমের ওষুধ, বুঝে নেবেন, সে ব্যামো ওষুধে সারে না।1 —Syed Mujtaba Ali, চাচা কাহিনী (1955) introduction Mankind’s fascination with spice dates back at least 8,000 years—both culinary and medicinal herbs are referenced in the Vedas, Hinduism’s oldest religious text. Spice is also peppered throughout the Old Testament.2 The Song of Solomon recites: “Thy plants are an orchard of pomegranates, with pleasant fruits; camphire, with spikearion 28.1 spring/summer 2020 2 a vexed pharmacopeia nard and saffron; calamus and cinnamon, with all trees of frankincense; myrrh and aloes, with all the chief spices.”3 Every one of these fruits, plants and spices remained popular in the West throughout antiquity, into the Middle Ages, and beyond. As early as 3000 bc, trade routes had connected the Mediterranean to the near east. Courtesy of this “Spice Road,” ancient Mediterranean civilizations had access to a wide range of horseradishes, mustards, peppers, gingers and other spices. The Greeks and Romans had a special relationship with black pepper—so much so that four out of five recipes in Apicius’s famous 1st century cookbook4 called for a sprinkling of this sometimes-costly commodity. It is perhaps not coincidental that black pepper contains heat-producing alkaloids very similar to those found in New World chili peppers. Much has been written about the important role of chilis in South and Central American culture—a region that, by the Middle Ages, was in many respects the equal of Europe in “artistic sensibility, social complexity, and political organization.”5 The habanero and its capsainoid cousins were at the heart of the culinary and ceremonial customs of Mesoamerica, their biting heat and florid livery an apt metaphor for the “extravagant feats of human butchery”6 —very much in the tradition of the spectacular venationes of ancient Rome—for which the Aztecs at least were well known. To what extent was hot spice also a significant part of the culinary, medical and cultural landscape of the Old World? At a conference hosted by the Institute for Digital Archaeology at the University of Oxford last December, experts from Europe and North America examined the literary, historical, archaeological and scientific evidence around these questions. Their inquiry received a boost from new and rapidly developing techniques for examining the physical evidence of ancient diet and food production—laboratory techniques not available even five years ago. There was also fresh medical evidence to consider: significant research is being done in the area of chemosensation in the context of spicy foods. This Roger Michel, Alexy Karenowska, George Altshuler, Matthew Cobb 3 includes trying to understand how different so-called “TRP channels” in the nervous system process spice information— in particular, the connection between spice and endorphin levels. It appears that many of the hot spices available in antiquity could potentially trigger the same TRP channels as the capsaicin-charged Mesoamerican peppers. This creates a nice connection between old and new world spice that helps to explain and contextualize both. However, in the end, firm conclusions at the Oxford conference were scarce. It quickly became clear that more work, a greater diversity of viewpoints, better refined questions, and a change of venue were required to make additional progress. To paraphrase William Boot, the accidental protagonist of Evelyn Waugh’s autobiographical Scoop (wherein events around... (shrink)

Over the last 102 years, a lot of discussion was being held about the psychoanalytic conception of the “death drive,” but still with inconclusive results. In this paper, we start with a brief review of Freud’s conception, followed by a comprised overview of its subsequent support or criticisms. The core of our argument is a systematic review of current biochemical research about two proposed manifestations of the “death drive,” which could hopefully move the discussion to the realm of science. It (...) was already established that drive satisfaction leads to the secretion of beta-endorphins, and research evidence also shows that the same biochemical mechanisms get activated in the case of masochism and the gambling disorder but only if they are preceded by chronic frustration of the essential drives. We conclude that the actual situation is more complex than Freud hypothesized, and that a fundamental revision of the psychoanalytic drive theory is necessary. (shrink)

A much-cited definition of placebo is from Shapiro and Shapiro :"any therapy that is intentionally or knowingly used for its nonspecific, psychological, or psychophysiological, therapeutic effect, or that is used for a presumed specific therapeutic effect on a patient, symptom, or illness but is without specific activity for the condition being treated". What nonspecific means and how it relates to the psyche has been written about extensively yet inconclusively. In the end, the term nonspecific doesn't say anything about the crux (...) of the matter.Talking about placebo, one first has to distinguish between " placebo effect proper" and "perceived placebo effect."
