SUMMARY:Greg Bryant - Social and linguistic functions of prosodic cues in speech: an \nevolutionary approach
DESCRIPTION:Greg Bryant: UCSC Dept. of PsychologyDuring speech communication\, conversationalists produce and understand many simultaneous pieces of information through prosodic features of the voice (i.e.\, pitch\, loudness\, and duration properties). Prosodic variations provide cues to lexical and grammatical units (linguistic prosody)\, as well as emotional and intentional information (affective prosody). But prosody may also be used by conversationalists to signal social information not necessarily linked to the meaning of the words used. In this talk I will present various research examining prosody production and perception in both linguistic and social contexts. I will then discuss related ideas concerning linguistic and affective prosodic distinctions\, functional dissociations in pitch production including potential laryngeal specializations\, and evidence for pitch perception differences between tone and non-tone language speakers. I will argue that prosodic communication systems are functionally organized and future research should examine correspondences between production systems and perceptual response biases.

SUMMARY:Alan Dixson - Sperm competition\, mammalian reproduction\, and human evolution
DESCRIPTION:Alan Dixson: Center for Reproduction of Endangered Species\, Zoological Society of San DiegoThis talk focuses upon the structure and functions of the reproductive organs of mammals\, as viewed from the perspective of sexual selection and sperm competition. The living collections of the Zoological Society of San Diego contain many rare and unusual species; valuable anatomical material becomes available whenever necropsies are performed. Comparative studies have allowed us to demonstrate effects of sexual selection upon sperm morphology\, structure of the vas deferens\, accessory sexual glands\, and oviductal morphology in a variety of mammals. Inclusion of measurements of the human reproductive system in these studies has also provided some useful insights into the evolution of human sexuality.
