Adam Sparks – Who takes risks, and why?

Adam Sparks: UCLAWho takes risks, and why? Does risk-taking in one context predict risk-taking in other contexts? Attempting to answer these questions, I present a general conceptual model of decision-making under risk that integrates two inter-related pathways to risk-taking. The need-based pathway describes strategic response to competitive disadvantages; the ability-based pathway exploits competitive advantages. This […]

Marco Del Giudice – A unifying framework for evolutionary psychopathology

Marco Del Giudice: University of New MexicoEvolutionary approaches to psychopathology have generated many innovative models of specific mental disorders, as well as a growing empirical literature. However, the field as a whole remains highly fragmented, and has not yet produced a biologically grounded alternative to existing classification systems. In this talk I introduce a unifying […]

Jeffrey Schank – The Evolution of Fairness

Jeffrey Schank: UC DavisThere are many theoretical approaches to explaining fairness, but explaining fairness without leverage (e.g., genetic relatedness, punishment, or retaliation) is especially challenging. The dictator game (DG) is a fairness game without leverage. One player, the dictator, is given a divisible quantity of some resource (typically money) and must decide how much to […]

Ketema Paul – The Ability to Recover from Sleep Loss is Regulated by Biological Clocks in Skeletal Muscle Tissue

Ketema Paul: University of California, Los AngelesSleep loss can severely impair cognitive performance, yet the ability to recover from sleep loss is not well understood. Sleep regulatory mechanisms are assumed to lie exclusively within the brain mainly due to the strong behavioral manifestations of sleep. Whole-body disruptions of circadian biological clocks in mice are known […]

Cristine H. Legare – The Evolution and Ontogeny of Cultural Learning

Cristine H. Legare: University of Texas at AustinHumans display a wide repertoire of socially acquired and transmitted behaviors that vary substantially across populations. Information is accumulated and transferred within and across generations through the process of cumulative culture. What are the evolved psychological mechanisms that underlie cultural learning and how do they develop over the […]

Kevin Langergraber – Group Augmentation, Collective Action, and Territorial Boundary Patrolling by Male Chimpanzees

Kevin Langergraber: Arizona State UniversityMany animals carry out activities together because the benefits derived from collective action exceed those that can be achieved individually. But how can collective action evolve when individuals benefit from cooperation regardless of whether they pay its participation costs? According to one influential perspective, collective action problems are common, especially when […]

Claudia Valeggia – Life history (and other) transitions among the Qom of Argentina

Claudia Valeggia: UC DavisThis talk will be about change and how we experience it. Humans go through several transitions during the course of their life. The transition from one life history phase to the next, e.g. from infancy to childhood or from reproductive to post-reproductive life, represents a physiological challenge as well as a sociocultural […]
