Michael J. Owren is Assistant Professor in the Department of Psychology at Cornell University in Ithaca, NY. His work has examined primate audition and perceptual processing of species-typical sounds, vocal development, and acoustic analysis of vocalizations in vervets, macaques, baboons, and proboscis monkeys. His current interests include the role of nonlinear dynamics in primate calls and nonlinguistic aspects of human vocal behavior.
Drew Rendall is Assistant Professor in the Department of Psychology and Neuroscience at the University of Lethbridge in Lethbridge, Alberta. His interests are in the intersection and evolution of social behavior, communication, and cognition. He combines detailed acoustic analyses with field tests of specific hypotheses about signal structure and function. His current research is focused on the vocal communication of baboons.
