SUMMARY:Margo Wilson & Martin Daly - Carpe diem: adaptation and devaluing the future
DESCRIPTION: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\, which will be the focus of discussion.

SUMMARY:Jeffrey Brantingham - Gone in 6 Seconds: the Foraging Behavior of Los Angeles Car Thieves
DESCRIPTION: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 of the foraging behaviors deployed by car thieves are linked to psychological and behavioral capacities that evolved among our hunter-gatherer ancestors. It is less likely that there is specialized (or broken) cognitive module linked to “deviant behavior”. A dash of both trial-and-error and social learning mixed with generalized psychological and behavioral capacities is sufficient to generate very effective car thieves.

SUMMARY:Shinobu Kitayama - Voluntary Settlement and the Spirit of Independence
DESCRIPTION: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 group of people even in the midst of an entirely different cultural ethos of interdependence as long as the group had undergone voluntary settlement in the recent past. We thus examined residents of Japan’s northern island (Hokkaido). Hokkaido was extensively settled by ethnic Japanese from the 1870’s for several decades. Many of the current residents of Hokkaido are the descendents of the original settlers from this period. As predicted\, Japanese socialized and/or immersed in Hokkaido were nearly as likely as European Americans in North America to commit a dispositional bias in causal attribution\, to associate happiness with personal achievement\, and to show a personal dissonance effect wherein self-justification is motivated by a threat to personal self-images. In contrast\, these marker effects of independent agency were largely absent for non-Hokkaido residents in Japan. Implications for theories of cultural change are discussed.

SUMMARY:Gregory F. Grether - Environmental Change\, Phenotypic Plasticity and Genetic Compensation
DESCRIPTION: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 thus natural selection would usually be expected to favor genetic changes that gradually restore the ancestral form of the trait in the new environment.  I recently coined the term “genetic compensation” to describe this form of adaptive evolution. When genetic compensation occurs along a spatial environmental gradient\, it partially or completely masks the effects of the gradient on trait development. This means that populations of a species that look the same in the wild may develop quite differently if placed in a common environment. In addition\, genetic compensation may lead to a cryptic form of reproductive isolation between populations\, explain some puzzling cases in which heritable traits exposed to strong directional selection fail to show the expected evolutionary response\, and complicate efforts to monitor populations for signs of environmental deterioration. In this talk\, I will explain how genetic compensation differs from related phenomena\, such as genetic assimilation and canalization\, and review putative examples to illustrate the above points.
