Leda Cosmides: UC Santa BarbaraAccording to the alliance detection hypothesis, racial categorization is a (reversible) byproduct of cognitive mechanisms that evolved for detecting social alliances (Kurzban, Tooby & Cosmides, 2001; Pietraszewski, Cosmides & Tooby, 2014). In southern California, showing subjects a single social interaction in which race is uncorrelated with alliance patterns produces a sharp […]

Katarzyna (Kasia) Pisanski: UCLABody size can have an immense impact on the biology, ecology, and social status of an animal, but so too can ones ability to advertise or assess body size. Many species communicate their size vocally. Research investigating vocal communication of physical size in mammals, including humans, has focused on two salient and […]

Kiley Hamlin: University of British ColumbiaHow do humans come to have a “moral sense”? Are adults’ conceptions of which actions are right and which are wrong, of who is good and who is bad, who deserves praise and who deserves blame wholly the result of experiences like observing and interacting with others in one’s cultural […]

Hanna Kokko: Australian National UniversityA lot of evolutionary theory involves the concept of populations climbing towards peaks of higher fitness. Such theory has been written without taking into account that in most species there are two distinct classes of individuals — males and females — that influence the evolutionary process in a distinctly different way. […]

Nancy Dess: Occidental CollegeIn a 2002 BEC talk, I described the working hypothesis that bittersweet taste is a marker for sensitivity to metabolic equanimity, manifested in ways ranging from responsiveness to energy balance to emotional reactivity and stress vulnerability; data from rats selectively bred on a saccharin phenotype and, to a lesser extent, humans, were […]

Larry Cahill: UC IrvineAbstract: Historically, neuroscience paid little if any attention to sex influences outside a limited area of reproductive functions. But all that is changing, and ever rapidly, with a flurry of discoveries the past 10 years in particular about sex influences on brain function down to the molecular level. My area of emotional […]

Simone Schnall: University of CambridgeTraditional theories of perception have assumed that visual processing is not influenced by top-down cognitive processes and is thus driven entirely by physical properties of the environment (Pylyshyn, 1984). For example, how a person sees stimuli such as a cup of coffee or a steep hill was thought to be only […]

Thom Scott-Phillips: Durham UniversityLanguage is arguably humanity's most distinctive characteristic. What, exactly, is language, and why are we the only species that has it? In this talk, based upon my recent book*, I will argue that the differences between human communication and the communication systems of all other species is probably not a difference of […]

Gregory Clark: UC DavisMost work studying the inheritance of aspects of social status across societies suggests two things. The first is that this inheritance is weak. Most social status for people is not determined by inheritance from parents. The second is that the strength of inheritance of status varies markedly across societies, so that status […]

Henrike Moll: USCHumans are an extraordinarily social species. Their unique way of relating to one another becomes evident very early in ontogeny. In this talk, I will present two lines of experiments, both of which exemplify toddlers’ attunement to other persons and their awareness of others’ perceptual and epistemic states. In one line of experiments, […]
