SUMMARY:Uri Gneezy - Gender differences in preferences
DESCRIPTION:Uri Gneezy: UCSD Rady School of Management Arthur Brody Endowed Chair in Management Leadership\, Professor of Management and StrategyIn this talk I will discuss some recent findings regarding gender differences in economic experiments. The discussion will focus on gender differences in competitiveness\, but will also touch on differences in risk preferences and social preferences. I will also speculate on the source of these differences\, as well as on their implications.http://www.bec.ucla.edu/GneezyPaper.pdf

SUMMARY:Erol Akcay - Evolution of motivations and behavioral responses: Integrating the proximate and ultimate causes of behavior
DESCRIPTION:Erol Akcay: University of Tennessee National Institute for Mathematical and Biological Synthesis (NIMBioS)There is extensive work on the evolutionary causes of social behaviors\, but integration of this theory with the proximate mechanisms of behavior has lagged behind. Here\, I will present a new modeling approach to achieve such integration. The model rests on goal-oriented motivations\, or preferences\, as the proximate determinants of behavior and describes the dynamics of a social interaction at the behavioral time scale. During these behavioral dynamics\, individuals can respond to each other’s actions\, and these responses ultimately drive the evolution of the proximate motivations.  \nWe first apply this framework to the question of other-regarding motivations. We find that other-regarding motivations can evolve even when there is complete conflict of interests between the individuals\, and in the absence of group- or kin-selection. We then turn our attention to the evolution of conformist motivations\, and explore conditions that facilitate their evolution. Finally\, we generalize our framework to include the joint effects of behavioral responses trough proximate mechanisms and selection in structured populations. The resulting model illuminates the interplay between behavioral responses and relatedness in the evolution of social behaviors. In particular\, we find that behavioral responses can facilitate the evolution of group-optimal behaviors\, and result in transitions between levels of selection.

SUMMARY:Thomas Flamson - Encryption Theory: The evolution of humor as an honest signal
DESCRIPTION:Thomas Flamson: Santa Monica College Department of Earth Science / UCLA Department of AnthropologyThe Encryption Theory of Humor proposes that humor evolved as a means of signaling similarity in locally variable personal features in order to facilitate assortment with the most compatible peers within the local group. It claims that a necessary component of humorous production is the presence of multiple\, divergent understandings of speaker meaning\, some of which are dependent on access to implicit information. Because of this dependence\, only those listeners with access to this background knowledge can “decrypt” the implicit understandings\, which further entails the inference that the speaker shares that access. This provides a channel for the honest signaling of personal features\, which enables within-group assortment for compatible long-term interaction partners such as friends or mates. \nThis talk will present a range of data supporting various aspects of this hypothesis\, obtained both through online studies with literate Western participants\, and ethnographic observation and studies conducted in rural northeastern Brazil. It will be shown that (a) prior knowledge interacts with information provisioning to impact individual humor preferences\, (b) these preferences reflect closeness in real-world social networks\, and (c) evaluations of the sense of humor of other individuals also reflect social closeness. These findings support the hypothesis that humor evolved as a subjective\, interdependent signaling system for compatibility matching\, and not simply as an index of objectively-evaluated traits\, such as intelligence.

SUMMARY:Robert Wayne - Evolution and diversification of the domestic dog
DESCRIPTION:Robert Wayne: UCLA Department of Ecology and Evolutionary BiologyThe domestic dog is one of our most remarkable inventions. The behavioral and functional diversity of the dog far surpasses that of its wild progenitor\, the gray wolf. Similarly\, in size and proportion\, dogs exceed the diversity of the entire carnivore order. The dog genome project and recent advances in biotechnology have enabled a new understanding of the process of domestication and diversification. I discuss our recent molecular findings concerning the origin of the dog and present a new evolutionary tree of dogs that leads to a better understanding of the nature of artificial selection and how it has shaped the diversity of our closest animal companion. \n*(Co-Sponsored by the UCLA Center for Society and Genetics)
