James Roney – Preliminary data testing an alternative explanation for menstrual phase effects on women’s mate preferences

James Roney: UC Santa Barbara Department of PsychologyMenstrual cycle shifts in women's mate preferences have generally been interpreted as products of adaptations designed to alter behavior during the fertile window relative to other times in the cycle. I will discuss an alternative theory that posits that such shifts may be produced by mechanisms designed to […]

Janet Sinsheimer – Family Feuds: Maternal-Fetal Genotype Incompatibility

Janet Sinsheimer: UCLA Departments of Human Genetics, Biomathematics and BiostatisticsBiological mechanisms involving a combination of genetic and environmental factors have been hypothesized to explain susceptibility to complex familial disease. I will present our efforts to detect interactions between mother's and child's genes that may create adverse prenatal environments and increase susceptibility to diseases such as […]

Carl Lipo – Resolution of the Cultural Phylogenies of Monumental Statues on Easter Island

Carl Lipo: CSU Long Beach Department of AnthropologyThe monumental statues (moai) of Easter Island represent substantial investment in cultural elaboration by the prehistoric islanders. Constructing explanations of these features requires generating measurements of temporal and spatial statue variability. Using a method based in cultural transmission, cladistics and occurrence seriation I present the results of analysis […]

Stacey Rucas – Allies and Rivals: The Complex world of women’s social dynamics among the Tsimane of Bolivia

Stacey Rucas: California Polytechnic State University Department of Social SciencesThis research examines the complexity of women's social behaviors with other women through various modes of evolutionary inquiry and methods. Results indicate that women engage in alternating forms of competitive and cooperative behaviors across the lifecourse in their quest for reproductively limiting resources. Data presented will […]

Alison Gopnik – Causal maps and Bayes nets: Causal inference and theory formation in children, scientists and computers

Alison Gopnik: UC Berkeley Department of PsychologyHow do we accurately infer the causal structure of the world around us? Thirty years of developmental research has shown that human children form and revise intuitive theories of everyday physics, biology and psychology. These theories are similar to the formal theories of science. Recent work in philosophy of […]

Hanna Kokko – Love and hatred in a world of feedback

Hanna Kokko: University of Helsinki Department of Biological and Environmental SciencesI will present results on both `love´ (sexual selection) and `hatred´ (territorial conflict). In both cases I will investigate the role of `feedback´, that is, ask the question how strongly individual behaviour influences population dynamics, which then feeds back to influence what is adaptive at […]

Mark Kleiman – Maximizing cooperation while minimizing punishment

Mark Kleiman: UCLA Department of Public PolicyThe threat of punishment can facilitate cooperation by discouraging defection and aggression. Because punishment is scarce, costly, and painful, optimal enforcement strategies will minimize the amount of actual punishment required to effectuate deterrence. If potential offenders are deterrable, increasing the conditional probability of punishment (given violation) can reduce the […]

Mary Towner – Investigating cultural macroevolution and trait transmission in the Western North American Indian database

Mary Towner: UC Davis Department of AnthropologyCultural traits are distributed across human societies in a patterned way. Study of the mechanisms whereby cultural traits persist and change over time is key to understanding human cultural diversity. For more than a century, a central question has engaged anthropologists interested in the study of cultural trait variation—what […]

Gian Gonzaga – Is there an “I” in “We”?

Gian Gonzaga: eHarmony.comRelationships are often studied through one of two questions. How does the relationship benefit the individual and/or how does the relationship benefit the dyad? This talk will address the challenges of balancing what is good for me, what is good for my partner, and what is good for the relationship. It will then […]

Andrew Shaner – Age at onset of schizophrenia: Evidence of a latitudinal gradient

Andrew Shaner: UCLA VA HospitalVariation in the age at onset of a multifactorial disease often reflects variation in cause. In this talk, I show a linear latitudinal gradient in the mean age at onset of schizophrenia in 13 northern-hemisphere cities, ranging from 25 years old in Cali, Columbia (at 4 degrees north) to 35 years […]
