In this talk, Elizabeth Spelke (Harvard Univ) asks whether studies of human infants provide insights into the origins and nature of uniquely human social cognitive capacities. Do the complex social judgments made by human adults develop from, and build on, simpler systems that are functional in infants? And do non-human animals share any of these systems, and therefore serve as models for studies of their development and functioning at multiple levels of analysis? Recent research on human infants suggests tentative answers to these questions. Recorded on 10/18/2013. (#26083)
