SUMMARY:Michael Tomasello - Becoming human: A theory of ontogeny
DESCRIPTION:Becoming human: A theory of ontogeny\nMichael Tomasello\nDuke University and the Max Planck Institute for Evolutionary Anthropology\nHumans are biologically adapted for cultural life in ways that other primates are not. Humans have unique motivations and cognitive skills for sharing emotions\, experience\, and collaborative actions (shared intentionality). These motivations and skills first emerge in human ontogeny at around one year of age\, as infants begin to participate with other persons in various kinds of collaborative and joint attentional activities\, including linguistic communication. Our nearest primate relatives understand important aspects of intentional action – especially in competitive situations – but they do not seem to have the motivations and cognitive skills necessary to engage in activities involving collaboration\, shared intentionality\, and\, in general\, things cultural. \n

SUMMARY:Dorsa Amir - The development of decision-making across diverse cultural contexts
DESCRIPTION:The development of decision-making across diverse cultural contexts\nDorsa Amir\nBoston College Department of Psychology\nThe human behavioral repertoire is uniquely diverse\, with an unmatched flexibility that has allowed our species to flourish in every ecology on the planet. Despite its importance\, the roots of this behavioral diversity — and how it manifests across development and contexts — remain largely unexplored. I argue that a full account of human behavior requires a cross-cultural\, developmental approach that systematically examines how environmental variability shapes behavioral processes. In this talk\, I use the development of decision-making across diverse contexts as a window into the relationship between the socioecological environment and behavior. First\, I present the results of a cross-cultural investigation of risk and time preferences among children in India\, Argentina\, the United States\, and the Ecuadorian Amazon\, suggesting that market integration and related socioecological shifts lead to the development of more risk-seeking and future-oriented preferences. Second\, I present the early results of a five-culture investigation into the ontogeny of social preferences — namely\, trustworthiness\, forgiveness\, and fairness. Taken together\, these studies help elucidate the developmental origins of behavioral diversity across cultural contexts\, and underscore the utility of interdisciplinary research for explaining human behavior. \n  \nNote: video of this presentation is not available.

SUMMARY:Paul Smaldino - The evolution of covert signaling in diverse societies
DESCRIPTION:The evolution of covert signaling in diverse societies\nPaul Smaldino\nDepartment of Cognitive and Information Sciences\, University of California\, Merced\nIdentity signals are common components of communication transmissions that inform receivers of the signaler’s membership (or non-membership) in a subset of individuals. Signals can be overt\, broadcast to all possible receivers\, or covert\, encrypted so that only similar receivers are likely to perceive their identity-relevant meaning. I’ll present an instrumental theory of identity signaling as a mechanism for social assortment\, formalized with both analytical and agent-based models. Covert signaling is favored when signalers are generous toward strangers\, when costs of being discovered as dissimilar are high\, and when the ability to assort only with preferred partners is restricted. Covert signaling should be more common among members of “invisible” minorities\, who are less likely to encounter similar individuals by chance. I’ll also discuss empirical projects underway to test and extend this theoretical framework using online political communication. This work has implications for theories of signaling and cooperation\, social identity\, pragmatics\, politics\, and the maintenance of diversity. \n
