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: 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: 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: 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: 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 […]
Chris Dunkel Schetter: University of California, Los AngelesIn this talk, Prof Dunkel Schetter will touch on conceptions of stress, background on birth outcomes, and summarize briefly findings on stress and preterm birth and low birthweight. She will present findings from her own program of work on pregnancy anxiety as a risk factor for preterm birth […]
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: 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 […]
