SUMMARY:Katarzyna (Kasia) Pisanski - The Sound of Size: Human Vocal Communication of Body Size
DESCRIPTION: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 largely independent features of the voice: fundamental frequency and/or corresponding harmonics (perceived as voice pitch) and formant frequencies (resonance frequencies of the supralaryngeal vocal tract). In this talk\, I will discuss the degree to which fundamental and formant frequencies reliably predict variation in body size controlling for sex and age\, and their relative role in the perception or accurate estimation of body size in humans. The findings that I will present corroborate work on many other mammals whose mechanisms of vocal production\, including anatomical constraints on size exaggeration\, parallel those of humans. However\, my findings also highlight the impact of psychoacoustic\, sociocultural and perceptual biases on size communication in humans.

SUMMARY:Kiley Hamlin - Moral Babies: Preverbal Infants Know Who and What are Good and Bad
DESCRIPTION: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 environment and explicit teaching from parents\, teachers\, and religious leaders? Do all of the complexities in adult’s moral judgments reflect hard-won developmental change coupled with the emergence of advanced reasoning skills? This talk will explore evidence that\, on the contrary\, preverbal infants’ social preferences map surprisingly well onto adult moral intuitions. Within the first year of life\, infants prefer those who help versus harm third parties\, those who reward prosocial individuals and punish wrongdoers\, and even privilege the intentions that drive actions over the outcomes they lead to. the second year of life\, toddlers direct their own helpful actions toward helpful individuals\, and harmful actions toward harmful individuals. These results suggest that our adult moral sense is supported\, at least in part\, by innate mechanisms for social evaluation.

SUMMARY:Hanna Kokko - Males exist. Does it matter? -- Special Time -- 9:00am
DESCRIPTION: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. I will talk about this\, and try to shed some light on two quite broad questions: why do males exist\, and what determines how they behave?

SUMMARY:Nancy Dess - A Pan-Mammalian Tongue-Microbiome-Gut-Brain Axis? Implications for Health and Culture
DESCRIPTION: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 presented in support of the hypothesis.  This talk provides an update on our research program\, including social behavior and evidence of an association between the taste phenotype and the gut microbiome.  I will draw on others’ recent research with nonhuman primates (taste polymorphisms and behavioral ecology) and humans (embodied cognition) to advocate for refinement and testing of multilevel integrative models that link individual-level taste to processes at lower (gut-brain axis) and higher (sociality\, culture) levels of organization.
