Francisco J. Ayala – Darwin’s Greatest Discovery: Natural Selection versus Intelligent Design

Francisco J. Ayala: UCI Departments of Ecology & Evolutionary Biology and PhilosophyDarwin is deservedly given credit for the theory of biological evolution. He accumulated evidence demonstrating that organisms evolve and diversify through time. Most important, however, is that he discovered natural selection, the process that accounts for the adaptive organization of organisms and their features; […]

Paul Zak – Oxytocin Increases Trust in Humans

Paul Zak: Claremont Graduate University Neuroendocrine Foundations of Trust Department of EconomicsThe traditional view in economics is that individuals respond to incentives, but absent strong incentives to the contrary selfishness prevails. Moreover, this “greed is good” approach is deemed “rational” behavior. Nevertheless, in daily interactions and in numerous laboratory studies, a high degree of cooperative […]

Margo Wilson & Martin Daly – Carpe diem: adaptation and devaluing the future

Margo Wilson & Martin Daly: McMaster University Department of PsychologyThe future is almost always worth less to organisms than the present, and evolved psychologies and physiologies 'discount' it accordingly. However, exactly how they do so, how they should do so, and whether real discount functions match theoretical expectations, are unresolved and/or controversial in various details, […]

Jeffrey Brantingham – Gone in 6 Seconds: the Foraging Behavior of Los Angeles Car Thieves

Jeffrey Brantingham: UCLA Department of Anthropology How specialized is your average Los Angeles "auto boost"? This talk draws on both new and classic foraging models to examine the search strategies deployed by Los Angeles car thieves and evaluates the decision making process underlying how they select individual cars to steal. It seems plausible that many […]

Shinobu Kitayama – Voluntary Settlement and the Spirit of Independence

Shinobu Kitayama: University of Michigan Department of PsychologyThere is a general consensus that the history of voluntary settlement in the western frontier constitutes a major element of American individualism. Yet, if voluntary settlement is a causal factor that promoted tacit beliefs and practices of independent agency, there should be similar beliefs and practices among a […]

Gregory F. Grether – Environmental Change, Phenotypic Plasticity and Genetic Compensation

Gregory F. Grether: UCLA Department of Ecology and Evolutionary BiologyNormal development depends on specific environmental inputs. Consequently, when a species encounters novel environmental conditions, some traits may develop abnormally. Changes in the environment can occur, for example, because of climate change or habitat degradation. Like genetic mutations, most environmental perturbations of development are detrimental, and […]

Craig McKenzie – Framing Effects and Rationality

Craig McKenzie: UC San Diego Department of PsychologyFraming effects are said to occur when "equivalent" redescriptions of objects or outcomes lead to different preferences or judgments. For example, a medical treatment is seen more favorably when described as resulting in "90% survival" rather than "10% mortality." Such effects are widely considered to be classic violations […]

Steven Gaulin – A Real-World Foraging Task Yields a Female Advantage and Significant Content Effects.

Steven Gaulin: UCSB Department of AnthropologyThough Silverman and Eals division-of-foraging-labor hypothesis cannot explain the cross-species distribution of sex differences in spatial ability, it does make a novel prediction: women will more accurately remember the location of stationary resources. Unfortunately, Silverman and Eals’ own tests of this hypothesis have yielded weak and inconsistent support, possibly because […]

Rafael Nuñez – Embodied Cognition, Objectivity, and Truth: Lessons from Mathematics and Spatial Construals of Time in Aymara

Rafael Nuñez: UCSD Department of Cognitive ScienceHow can we "objectively" share abstract entities with others, in a stable and consistent way? How can we evaluate "Truth" when purely imaginary entities are concerned? Mathematics provides a very intriguing case for studying these questions. Indeed, mathematics, on the one hand deals with purely imaginary entities (e.g., a […]
