This talk examines evolutionary, developmental psychology and social-cultural anthropology debates regarding how children learn from others. Cognitive psychologists and evolutionary biologists indicate that teaching, accurate imitation, and language are distinct features of human cognition that enable high fidelity transmission of cultural variants and cumulative culture. The talk examines whether or not one type of teaching, called natural pedagogy, and one type of accurate imitation, called overimiation, exist among Aka hunter-gatherers of the Congo Basin. These and other studies of teaching and learning in hunter-gatherers are presented and situated in the culturally constructed niches of intimate living and foundation schemas of equality, autonomy, and sharing.

This collaborative discussion focuses on the complex question: How and why do parents interact differently with sons and daughters? We approach these questions with the assumption that gender differences in parenting are expressed and performed in everyday interactions between parents and children and shape how children come to understand what it means to be "male" or "female" in their culture. Dr. Fivush will share insights from her research on the social construction of gender in family narratives; Dr. Mascaro will discuss recent findings on gender differences in paternal behavior and brain responses to children. We will also discuss how the social construction of gender is influenced by biology, and we will discuss the evidence that these gender differences in parenting help children construct notions of gender and influence children's social and emotional development.

Recent attempts to use findings in neuroscience to inform our understanding of religious experience have focused on explaining the origins of religious activity and belief as potential byproducts of neural structures that evolved for, and were exapted from, other biological functions. Brain mechanisms implicated in attributing agency, detecting intentions, social reward, pro-social adaptation, and other aspects of social cognition have variously been proposed as potential pathways leading to the emergence of commonalities in religion and ritual across cultures. Conversely, conditions where those mechanisms are perturbed or impaired are potentially useful in testing new theories in neurotheology. Most proposals in this area have neglected the role of development and early experience in shaping neural function throughout the lifespan. This presentation will provide an overview of recent research in developmental social neuroscience, in the context of autism, in order to explore the extent to which social cognit

Are non-clinical populations high on the autistic spectrum less likely to "get" religion? Building on the first talk, I ask whether autism increases the odds of disbelief, as has been predicted by some cognitive theories of religious belief. Probing further, I ask whether this link is statistically explained by the selective deficits in theory of mind associated with the autistic spectrum. Next I explore whether gender differences in autism and theory of mind offer a novel, if partial, explanation for the well-documented gender gap in religious belief. Further, I present new research on links between the schizotypal spectrum in non-clinical populations – a cluster of traits partly characterized by a hyperactive theory of mind – and hyper-religiosity. This link in turn may offer insights into the psychological profile of the "spiritual but not religious" phenomenon.

For a given person to believe in a deity or deities, she must (a) be able to form intuitive mental representations of supernatural agents; (b) be motivated to commit to supernatural agents (and related rituals) as real and relevant sources of meaning and control; and (c) have received specific cultural inputs that, of all the supernatural agents or forces one could possibly think of, one or more specific deities should be believed in and committed to. In this talk, I present these interrelated hypotheses from the new cognitive science of religion and the science of cultural evolution in light of the growing evidence from diverse fields. I also present new research about belief in karma in relation to cognitive theories. Throughout the talk I explore the current controversies and debates about the social cognitive and cultural learning capacities that make human beings a believing species. This talk was presented as part of the 2017 CMBC Summer Workshop.

The cognitive science of religion (CSR) illuminates similar features of experience that arise in religious settings and that are associated with some mental disorders. We endorse explanatory pluralism, the view that cross-scientific investigations are enriched by integrating theory, methods, and evidence from multiple analytical levels, and ecumenical naturalism, which holds that: (1) examining features of experiences in different mental disorders and similar features of religious experiences will offer insights about underlying mental systems that figure in both, (2) CSR’s by-product theory maintains that religious experiences rely on cultural triggers of maturationally natural mental systems that underpin various ordinary experiences, and (3) CSR’s methods, theories, and findings will provide leverage for explaining many similar features of mental disorders. Schizophrenics and some Christians not only hear voices but attribute those experiences to agents other than themselves. An examination of experiencing

The negative academic and health effects of ethnic/racial discrimination are robust and pervasive. Taking a biopsychosocial approach, the current study combines actigraphy with a daily diary design to explore sleep duration and quality as an explanatory link between discrimination and outcomes. In a sample of 189 ethnic/racially diverse 9th grade adolescents, the study first assessed the daily impact of discrimination on next-day academic engagement and mood. Second, the study explored sleep as a mediating pathway between discrimination and outcomes. This paper contributes to two timely, yet independent, developmental science literatures. First, the study contributes to a growing literature on how social experiences of discrimination may be embodied psychophysiologically to contribute to ethnic/racial academic and health disparities. Second, the study contributes to the burgeoning science of sleep and its importance for youth development. Intersecting these literatures, the study found that on days in which y

As a psychiatrist, psychoanalyst, and anthropologist, I will review and discuss the discourse on laughter. Traditionally, this discourse seems to summon to mind three principal characteristics of laughter: its specifically human nature, its structural relationship to the joy and pleasure procured by what is laughable, making laughter an indicator of “good health,” and its automatic, reflexive aspect. Unfortunately, it seems to obscure two fundamental aspects of laughter: its historicity and the complexity of its determinism. I think that laughter, like all human behavior, referring to human complexity, must be the object of a multi and interdisciplinary approach involving biological, psychological, historical and socio-cultural considerations. And one of the modes of their interaction may be supplied by the idea of communication. Indeed, traditionally perceived as being a facial emotional expression, laughter is fundamentally a mode of non-verbal communication of different types of affective messages among wh

Language Documentation is a reborn, refashioned, and reenergized subfield of linguistics motivated by the urgent task of creating a record of the world’s fast disappearing languages. In addition to producing resources for communities interested in language and culture preservation, maintenance, and revitalization, language documentation continues to produce data that challenge and improve linguistic theory. A case in point is a pattern of participant marking, i.e. ways that speakers indicate who does what to whom in a sentence, in the endangered languages of the Tibeto-Burman region (Northeast India). From current typological studies we expect one of three participant marking patterns and these are based on purely syntactic factors. From very small languages in and around the Himalayan region we discover that that there is a possible fourth pattern based not on syntax but on information structure and pragmatics – a game changing discovery for syntactic and typological theory. Endangered language data also pro

This talk discusses the wide-ranging potential of immersive virtual reality (IVR) as a research tool in the behavioral sciences. The speaker will discuss her research using IVR to study mundane judgments of the built environment, her emergency evacuation IVR work conducted with engineers and disaster experts, and her social-health work studying HIV risk behavior in highly interactive dating scenarios with virtual dating partners.

Why do today's religions look and function the way they do? Presenting research primarily on religion’s effects on prosocial behavior and prejudice toward outgroups, I will argue that the form and function of modern religions can be understood as the legacy of a millennia-long process of cultural evolution. Our recent research has begun to empirically test perennially debated questions about whether religions make people act more ethically, what functions religions have served, and why some religious traditions have fared better than others. The results reveal that while the social consequences of religion are not always desirable, they can be explained as the product of cultural adaptations that served vital social functions. In particular, I’ll discuss how recurrent elements throughout religions have served to stabilize cooperation among large groups of unrelated strangers, and maximize survival in intergroup competition. Finally, I’ll speak about how this cultural evolutionary perspective informs predictio

A chief stumbling block for a science of consciousness has always been that there are so few ways to measure consciousness. Recent developments in clinical neuroscience suggest a promising new start on this problem, and raise new empirical issues. The progress may also carry some surprising philosophical implications for realists about consciousness.

Scientists have made substantial progress in understanding the evolution of mammalian sleep, yet the evolution of human sleep has been largely ignored in comparative studies. This omission is surprising given the extraordinary mental capacity and behavioral flexibility of humans, and the importance of sleep for human cognitive performance. I will discuss new phylogenetic methods that enable rigorous investigation of sleep along a single evolutionary lineage, and will apply these methods to study human sleep and brain size. In addition, I will present new findings from my lab on sleep in traditional human populations, which sheds additional light on the evolution of human sleep. I will close by considering how evolutionary perspectives provide insights to human sleep disorders, health across the lifespan, and health disparities.

Alena Esposito and Donald Tuten discuss different aspects of research on bilingualism. Dr. Esposito focuses on recent cognitive and neuroscientific research on bilingualism, while Dr. Tuten focuses on fundamental questions in social and cultural approaches to research on bilingualism. Both presenters touch on and consider the implications of these approaches on education and educational approaches to research on bilingualism.

In June 2016, a small group of world-leading neuroscientists, ethicists, social scientists and clinical researchers came together with two goals: to initiate a global research consortium in neuroscience ethics; and to come up with a research agenda for that consortium. Were the goals met? Yes and no. In this talk I identify some of the key clashes, the strange alliances, and the isolation tactics that collectively enabled the consortium to establish an identity and a mission, at a cost. I will draw on some recent theories of disciplinarity to understand what happened in the meeting; but I will also suggest that a key problematic, that between ‘ethics’ and ‘values,’ has not been taken sufficiently seriously by those who endeavour to construct multi- and inter-disciplinary research initiatives in neuroscience ethics.

In my lab, we recently discovered a new type of cognitive bias brought on by the presence of a tip-of-the-tongue (TOT) state for a currently inaccessible word. When in a TOT state, participants think it more likely that a currently unretrievable word was presented in a darker, clearer font upon last seeing it, a larger font upon last seeing it, that it is of higher frequency in the language, and that it starts with a more common first letter in the language. This pattern suggests that TOT states bias people to infer that the unretrieved target information has qualities that tend to characterize fluency or accessibility, even when that is not the case. In further studies, we have found that the TOT’s biasing effects also extend to the immediately surrounding circumstances during the TOT as well. For example, people judge celebrity faces as belonging to more ethical people when in a TOT state for the name than when not, and rate their inclination to take an unrelated gamble as being higher when in a TOT state t

Recent NSF Program Directors Laura Namy and Victoria Powers discuss current funding opportunities from the National Science Foundation and secrets to a successful application.

Why does race serve as the most polarizing feature of American politics? Presumably, Americans have a stake in proclaiming America’s greatness, particularly touting pride in democratic governance, protecting civil rights and liberties, and making progress in areas that serve as ugly scars in its history. Yet research suggests the effects of racial bias now surpass the typical partisan and ideological predispositions that drive political decision making and judgments. This phenomenon is highlighted by public opinion data collected over the past 10 years covering Barack Obama’s presidential candidacy and subsequent administrations. As the prototypically racially neutral African American politician, Barack Obama was expected to inhibit the activation of negative racial appraisals and threat. Contrary to such expectations, a number of studies show this did not happen, as perceptions of Obama and his policies are linked strongly to negative racial attitudes. But negative racial attitudes are not limited to Obama;

What personality traits make for successful politicians? What contributes to political partisanship? In this heated election season, come join Dr. Alan Abramowitz (Political Science) and Dr. Scott Lilienfeld (Psychology) for a conversation about the factors influencing presidential elections from the standpoint of both voters and candidates. Dr. Abramowitz will discuss the growing political partisanship of the American electorate, and its potential sociological and political sources. Dr. Lilienfeld will discuss psychohistorical research on how personality variables (e.g., narcissism, extraversion, antagonism) among U.S. Presidents (and other leaders) predict their success and failure, as well as how such variables might shape voter choices.

Humans routinely confront situations that require coordination between individuals, from mundane activities such as planning where to go for dinner to incredibly complicated activities, such as multi-national agreements. How did this ability arise, and what prevents success in those situations in which it breaks down? To understand how this capability evolved across the primates, my lab uses the methodology of experimental economics. This is an ideal mechanism for the comparative approach as it is a well-developed methodology for distilling complex decision-making in to a series of simple choices, allowing these decisions to be compared across species and contexts using identical methodologies. We have investigated coordination in New World monkeys, Old World monkeys, and great apes, including both chimpanzees and humans. We find that there are remarkable continuities of outcome across the primates, including humans, however there are also important differences in how each species reaches these outcomes. For
