The Comparative Communication Lab studies the vocal interactions of songbirds, humans and other animals with an applied interest in the effects of human technologies on communication systems in our own and other species. Our methods include experimental tests of nonlinguistic human communicative capacities, wildlife bioacoustics and laboratory-based studies of developmental vocal learning and group interactive behavior in zebra finches. Our general approach seeks to understand the links between moment-to-moment communication dynamics and emergent social structures, in order to develop a comparative-species perspective on vocal interactivity.
