Eric Schniter – The Long Life of Skill Development among Tsimane Forager Horticulturalists

Eric Schniter: UC Santa BarbaraCollaborative research from the Tsimane Health and Life History Project has investigated whether age profiles of Tsimane skill development are consistent with life history theory predictions about the timing of productivity and reproduction. Life history models suggest that the especially long human lifespan co-evolved with large brains in a foraging niche […]

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 […]
