For as long as history has been with us, religion has been a feature of human life. There is no known culture for which we have an ethnographic or an archaeological record that does not have some form of religion. Even in the secular societies that have become more common in the past few centuries, there are people who consider themselves religious and aspire to practise the rituals of their religion. These religions vary in form, style and size from small (...) cults numbering a few hundred people centred around a charismatic leader to worldwide organizations numbering tens, or even hundreds, of millions of adherents with representations in every country. Some, like Buddhism, take an individualistic stance (your salvation is entirely in your own hands), some like the older Abrahamic religions view salvation as more of a collective activity through the performance of appropriate rituals, and a few (Judaism is one) have no formal concept of an afterlife. Some like Christianity and Islam believe in a single all- powerful God. (shrink)

Science is not a great way to make money, or these days, even a job. But there are great riches in it, and in this book too. Tim Bradford, 'New Scientist'.

The Oxford Handbook of Evolutionary Psychology is the definitive, comprehensive, and authoritative text on this burgeoning field. With contributions from over fifty experts in the field, the range and depth of coverage is unequalled. It will be an essential resource for students and researchers in psychology.

Cooperation for the public good is vulnerable to exploitation by free-riders because it always pays individuals to exploit the social contract for their own benefit. This problem can be resolved if free-riders are punished, but punishment is itself a public good subject to free-riding. The fear of supernatural punishment hypothesis (FSPH) proposes that belief in supernatural punishment might offer a solution to this problem by deflecting the cost of punishment onto supernatural forces and thereby incentivizing cooperation. FSPH is supported empirically (...) by ethnographic data, but this work has so far focused on (1) institutional cooperative traits which may not reflect individual choices on how to behave in everyday social interactions and (2) threat of punishment from all-powerful moralizing high gods rather than other agents capable of supernatural punishment. Here, we consider the FSPH using variables which are linked to individual interaction and expand the number of variables measuring belief in different forms of supernatural punishment. Our findings do not fit these more general FSPH predictions. We suggest there may be something special about the link between moralizing high gods and institutional enforcement of cooperation that is not captured by these other variables. (shrink)

When the social sciences parted company from evolutionary biology almost exactly a century ago, they did so at a time when evolutionary biology was still very much in its infancy and many key issues were unresolved. As a result, the social sciences took away with them an understanding of evolution that was in fact based on 18th- rather than 19th-century biology. I argue that contemporary evolutionary thinking has much more to offer the social sciences than most people have assumed. Contemporary (...) evolutionary research on human behaviour focuses on two main issues at the micro-social scale: understanding the trade-offs in individual decision-making and understanding the cognitive constraints that limit flexibility of decisions. I offer examples of both of these approaches. Finally, I consider the broader question of the macro-social scale. (shrink)

Humans have inherited from their remotest mammalian ancestors an integration of the sensory and motor systems that permits the exchange of signals and information, led by an instinctive response to harmonicity. The transition, from capacity for animal communication involving calls, facial expression and gestures, to modern human culture that embraces language, music, and dance, has resulted from anatomical adaptations such as upright posture, a distinct oro-facial and respiratory tract arrangement, and important changes in neural architecture, connectivity and plasticity. A key (...) development on which modern human vocal abilities depend was the achievement of a feedback loop between the perception and production of voiced sound that allows precise matching, imitation, and meaningful variation, of the acoustic properties: fundamental frequency, duration, amplitude, and timbre; all contributing to the capacity to coordinate simultaneous participation. These are the four specific properties that influence our sensations of sound. They play parallel and complementary roles in both language and vocal music, represented in blended synchrony such as unison song and collective speech as well as temporally organised and coordinated sequences such as call-and-response and polyphony. In turn, responding especially to the properties of the Harmonic Series, such features inform the musical employment of tools – musical instruments – that make use of materials available in the local environment (skin, bone, stone, bamboo, wood, etc.) to provide increased range and loudness as well as alternative timbres to those produced by the voice. We propose a framework by which the adaptations essential to such universal behaviours may have arisen, drawing on an extensive and varied literature to explore the potential of this position for illuminating the nature of human musicality and its relationship to language development.

Cooperation requires that individuals are able to identify, and preferentially associate with, others who have compatible preferences and the shared background knowledge needed to solve interpersonal coordination problems. The present study investigates the nature of such similarity within social networks, asking: What do friends have in common? And what is the relationship between similarity and altruism? The results show that similarity declines with frequency of contact; similarity in general is a significant predictor of altruism and emotional closeness; and, specifically, sharing (...) a sense of humor, hobbies and interests, moral beliefs, and being from the same area are the best predictors. These results shed light on the structure of relationships within networks and provide a possible checklist for predicting attitudes toward strangers, and in-group identification. (shrink)

One of the more compelling features of Denis Dutton’s The Art Instinct is its theoretical parsimony. Utilizing what essentially amounts to one explanatory principle—that of Darwinian selection—Dutton advances a theory of aesthetics that is at once general enough to account for cross-cultural variations in artistic production and sufficiently nuanced to promote insights into individual artworks. In doing this, Dutton’s work could not offer a greater contrast to some of the more vocal trends in contemporary aesthetic theory, where ponderous theorizing and (...) rebarbative jargons have violently opposed the idea—otherwise so modest—that aesthetic activities might draw on the evolved capacities of the human imagination.

Drama, at least according to the Aristotelian view, is effective inasmuch as it successfully mirrors real aspects of human behavior. This leads to the hypothesis that successful dramas will portray fictional social networks that have the same properties as those typical of human beings across ages and cultures. We outline a methodology for investigating this hypothesis and use it to examine ten of Shakespeare’s plays. The cliques and groups portrayed in the plays correspond closely to those which have been observed (...) in spontaneous human interaction, including in hunter-gatherer societies, and the networks of the plays exhibit “small world” properties of the type which have been observed in many human-made and natural systems.

Hormonal changes associated with the human menstrual cycle have been previously found to affect female mate preference, whereby women in the late follicular phase of their cycle (i.e., at higher risk of conception) prefer males displaying putative signals of underlying genetic fitness. Past research also suggests that romantic kissing is utilized in human mating contexts to assess potential mating partners. The current study examined whether women in their late follicular cycle phase place greater value on kissing at times when it (...) might help serve mate assessment functions. Using an international online questionnaire, results showed that women in the follicular phase of their menstrual cycle felt that kissing was more important at initial stages of a relationship than women in the luteal phase of their cycle. Furthermore, it was found that estimated progesterone levels were a significant negative predictor for these ratings. (shrink)

The original book chapter does not have an abstract. However, I have written an abstract for this repository: Religious life encompasses a wide diversity of situations for which the emotional tone is on a continuum from extreme euphoria to extreme dysphoria. In this book chapter, we propose the novel hypothesis that euphoria and dysphoria have distinctly separate functional consequences for religious evolution and survivability. This is due to the differential cognitive states that are created in euphoric and dysphoric situations. Based (...) on readings from religious studies and cognitive psychology, we propose that euphoria in religion is conducive to social bonding and situations needing lateral thinking and creativity; whereas dysphoria in religion is conducive to situations where precision and analogical reasoning are necessary.

Why and under what conditions are individuals altruistic to family and friends in their social networks? Evolutionary psychology suggests that such behaviour is primarily the product of adaptations for kin- and reciprocal altruism, dependent on the degree of genetic relatedness and exchange of benefits, respectively. For this reason, individuals are expected to be more altruistic to family members than to friends: whereas family members can be the recipients of kin and reciprocal altruism, friends can be the recipients of reciprocal altruism (...) only. However, there is a question about how the effect of kinship is implemented at the proximate psychological level. One possibility is that kinship contributes to some general measure of relationship quality (such as ‘emotional closeness’), which in turn explains altruism. Another possibility is that the effect of kinship is independent of relationship quality. The present study tests between these two possibilities. Participants (N= 111) completed a self-report questionnaire about their willingness to be altruistic, and their emotional closeness, to 12 family members and friends at different positions in their extended social networks. As expected, altruism was greater for family than friends, and greater for more central layers of the network. Crucially, the results showed that kinship made a significant unique contribution to altruism, even when controlling for the effects of emotional closeness. Thus, participants were more altruistic towards kin than would be expected if altruism was dependent on emotional closeness alone – a phenomenon we label a ‘kinship premium’. These results have implications for the ongoing debate about the extent to which kin relations and friendships are distinct kinds of social relationships, and how to measure the ‘strength of ties’ in social networks.

We propose Rhythmic Relating for autism: a system of supports for friends, therapists, parents, and educators; a system which aims to augment bidirectional communication and complement existing therapeutic approaches. We begin by summarizing the developmental significance of social timing and the social-motor-synchrony challenges observed in early autism. Meta-analyses conclude the early primacy of such challenges, yet cite the lack of focused therapies. We identify core relational parameters in support of social-motor-synchrony and systematize these using the communicative musicality constructs: pulse; quality; (...) and narrative. Rhythmic Relating aims to augment the clarity, contiguity, and pulse-beat of spontaneous behavior by recruiting rhythmic supports and relatable vitality; facilitating the predictive flow and just-ahead-in-time planning needed for good-enough social timing. From here, we describe possibilities for playful therapeutic interaction, small-step co-regulation, and layered sensorimotor integration. Lastly, we include several clinical case examples demonstrating the use of Rhythmic Relating within four different therapeutic approaches. These clinical case examples are introduced here and several more are included in the Supplementary Material. A suite of pilot intervention studies is proposed to assess the efficacy of combining Rhythmic Relating with different therapeutic approaches in playful work with individuals with autism. Further experimental hypotheses are outlined, designed to clarify the significance of certain key features of the Rhythmic Relating approach. (shrink)

Robin Dunbar's hypothesis that language capacity in response to the demands of maintaining large groups suggests a more specific hypothesis that language arose from a cognitive calculus by which animals could predict their status in complex dominance situations.

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)

Ordinary discourse is filled with discussions about ‘sexual orientation’. This discourse might suggest a common understanding of what sexual orientation is. But even a cursory search turns up vastly differing, conflicting, and sometimes ethically troubling characterizations of sexual orientation. The conceptual jumble surrounding sexual orientation suggests that the topic is overripe for philosophical exploration. This paper lays the groundwork for such an exploration. In it, I offer an account of sexual orientation – called ‘Bidimensional Dispositionalism’ – according to which sexual (...) orientation concerns what sex[es] and gender[s] of persons one is disposed to sexually engage, and makes no reference to one’s own sex and gender.

Music is a deeply entrenched human phenomenon. In this article, I argue that its evolutionary origins are intrinsically intertwined with the incremental anatomical, cognitive, social, and technological evolution of the hominin lineage. I propose an account of the evolution of Plio-Pleistocene hominins, focusing on traits that would be later implicated in music making. Such traits can be conceived as comprising the musicality mosaic or the multifaceted foundations of musicality. I then articulate and defend an account of protomusical behaviour, drawing theoretical (...) licence from the social brain framework of Robin Dunbar and colleagues, as well as the evolutionary framework for human culture and cooperation developed by Kim Sterelny. The role of gene-culture co-evolution and niche construction is brought to the fore in articulating the evolutionary account. Finally, I defend the view that music subsequently developed via processes of social learning and cumulative culture. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 31.1 (2007) 189-196MuseSearchJournalsThis JournalContents[Access article in PDF]Fiction and Theory of Mind: An ExchangeLisa Zunshine University of KentuckyBrian Boyd's review of my new book, Why We Read Fiction: Theory of Mind and the Novel (Ohio State University Press, 2006) engages a large variety of issues.1 I would like to address an important question about the integration of scientific methodology with literary analysis suggested by Boyd's discussion.2 As (...) I argue below, two different perspectives of this integration may mark two different—indeed, incompatible—ways of formulating the disciplinary goals and philosophy of the new field of cognitive literary theory.Why We Read Fiction makes a case for admitting the recent findings of cognitive psychologists into literary studies by showing how their research into the ability to explain behavior in terms of the underlying states of mind can furnish us with a series of surprising insights into our interaction with literary texts. Using as my case studies novels ranging from Richardson's Clarissa, Dostoyevsky's Crime and Punishment, and Austen's Pride and Prejudice to Woolf's Mrs. Dalloway, Nabokov's Lolita, and Hammett's The Maltese Falcon, I advance and explore a series of hypotheses about cognitive cravings that are satisfied—and created!—when we read fiction.Although my study draws on the already well-established as well as forthcoming work of numerous cognitive scientists (including Simon Baron-Cohen, Clark H. Barrett, Richard Byrne and Andrew Whiten, Leda Cosmides and John Tooby, Christopher Frith, Uta Frith, Paul Bloom, Susan Carey and Elizabeth Spelke, Peter Carruthers, Andy Clark, Antonio Damasio, Daniel Dennett, Alison Gopnik, Francesca Happe, Paul [End Page 189] Harris, Lawrence Hirschfeld, Stanley Klein, Alan Leslie, Andrew Meltzoff, Robert Mitchell, Keith Oatley, Gloria Origgi, Oliver Sacks, Dan Sperber, James Stiller, and Endel Tulving), it makes a point of being accessible to non-specialist readers. Cognitive science can be incredibly complicated and so can literary criticism, but I wanted to write a book on cognitive literary theory that does not scare anybody away with unnecessary jargon, knotty sentences, and overlong quotations. (Ironically, I must have succeeded too well in making my book reader-friendly and tucking my references in the endnotes since Boyd observes that I rely on only "a few findings" of cognitive scientists in my discussion.)The book consists of three parts. The first part, "Attributing Minds," introduces the first key theoretical concept of this book: mind-reading, also known as Theory of Mind. Drawing on the work of Simon Baron-Cohen (Mindblindness: An Essay on Autism and Theory of Mind), I suggest that fiction engages, teases, and pushes to its tentative limits our mind-reading capacity. Building on the recent research of Robin Dunbar and his colleagues, I then consider one particular aspect of Woolf's prose as an example of spectacular literary experimentation with our Theory of Mind. Finally, I turn to Steven Pinker's controversial analysis of Woolf in The Blank Slate to discuss the possibilities of a more profitable dialogue between cognitive science and literary studies.Of particular importance to this part of my argument is my belief that fictional narratives endlessly experiment with rather than automatically execute our evolved cognitive adaptations. When cognitive scientists succeed in isolating a certain regularity of our information-processing—for example, a constraint on the number of mutually reflecting minds that we can process with ease—we can take that constraint and see how it plays itself out in a fictional narrative. What we discover is that where there is a cognitive constraint, there is a "guarantee" of sorts that writers will intuitively experiment in the direction of challenging that constraint, probing and poking it and getting around it. The exact forms of such probing and poking will depend on specific cultural circumstances, including the mind-reading profiles of individual writers and their readers. The cognitive "limits" thus present us with creative openings rather than with a promise of stagnation and endless replication of established forms. This realization marks the possibility of a genuine interaction between cognitive psychology and... (shrink)

This paper starts from the remarkable habit of yoik singing among the Sámi people and the notion of togetherness in ‘singing together’, being confronted with the role of technology in the contemporary manifestations of ‘singing’. An important link appears to exist between several forms of grooming and the social dimensions of language and singing, as previously shown by Robin Dunbar. These types of interaction surpass the physiological, hormonal and psychological roles of grooming in humans, in non-human primates and (...) in other mammals. For they also determine the constraints of group-forming processes in mammals, and social structures in humans too. The characteristic group size of grooming mammals has been reported to determine the necessity of social stratification. Number constraints therefore form a silver lining throughout this paper. The analogy with artificial language models, and modern language models (MLM) in particular, has been chosen following the suggested applicability of AI for the deciphering of the language of Whales (Cetaceans). The polemic discussion between Noam Chomsky’s so-called classical generative linguistics and propagators of the nonlinguistic MLM approach (referring to Steven T. Piantadosi) is found an instructive heuristic for analyzing the future impact of AI on human culture. It is suggested that AI-generated analogues of ‘singing together’ will profoundly interact (or already do so) with social stratification and with the conservation of human values. (shrink)

Some researchers claim language as a solely human, even defining, attribute, while others claim that only humans are truly conscious.

The book begins with a thorough overview of what is known of the non-primate mind and its evolution. Following this, an international range of experts discuss in temporal sequence the human mind at various stages of evolution, beginning with the pre-hominids of 20 million years ago and ending with contemporary human behaviour. Accessible to students and researchers alike in psychology, anthropology, evolution, archaeology, and ethology, The Descent of Mind provides a range of provocative answers to the timeless question of what it means to be human.

Clique sizes for chimpanzee (Pan troglodytes) grooming and for human conversation are compared in order to test Robin Dunbar’s hypothesis that human language is almost three times as efficient a bonding mechanism as primate grooming. Recalculation of the data provided by Dunbar et al. (1995) reveals that the average clique size for human conversation is 2.72 whereas that of chimpanzee grooming is shown to be 2.18. The efficiency of human conversation and actual chimpanzee grooming over Dunbar’s (...) primate grooming model (always one-to-one and a one-way interaction) is 1.27 and 1.25, respectively, when we take role alternation into account. Chimpanzees can obtain about the same efficiency as humans in terms of quantity of social interactions because their grooming is often mutual and polyadic. (shrink)

A common objection to both contextualism and relativism about knowledge ascriptions is that they threaten knowledge norms of assertion and action. Consequently, if there is good reason to accept knowledge norms of assertion or action, there is good reason to reject both contextualism and relativism. In this paper we argue that neither contextualism nor relativism threaten knowledge norms of assertion or action.

This paper is an argument against Truthmaker Necessitarianism—the doctrine that the existence of a truthmaker necessitates the truth of the proposition it makes true. Armstrong’s sufficiency argument for necessitarianism is examined and shown to be question begging. It is then argued in detail that truthmaking is a matter of grounding truth and that grounding is a dependency relation that neither entails nor reduces to necessitation.
