Sergio M. Pellis is a Professor and Principal Investigator at the University of Lethbridge Canadian Centre for Behavioral Neuroscience. He has written and lectured extensively on play behavior in rodents and primates; contributed articles and chapters to many journal and books; and is coauthor of Playful Brain: Venturing the Limits of Neuroscience (2009), which encompasses three decades of empirical research supporting an integrated study of the multifunctionality of play and the differences that exist between the species. Vivien C. Pellis serves as Assistant Professor and postdoctoral fellow at the University of Lethbridge Canadian Centre for Behavioral Neuroscience. Her research interests include play behavior in animals and humans, autism, and righting reflexes, and she is coauthor of Playful Brain: Venturing the Limits of Neuroscience, as well as numerous other publications. Heather C. Bell is a doctoral candidate at the University of Lethbridge. Under the direction of Sergio M. Pellis, she is working on computational models of interacting systems of organisms. Bell’s coauthored articles have appeared in Behavioral Neuroscience and Behavioural Brain Research.

Stephen M. Siviy is Chairperson of the Psychology Department at Gettysburg College. His primary research interest is in identifying neurobiolical substrates of mammalian playfulness. With more than twenty years of experience in the field, Siviy’s coauthored articles have appeared in, among others, Behavioural Brain Research, Neuroscience & Biobehavioral Reviews, Journal of Comparative Psychology, and Behavioral Neuroscience. Siviy also served as a postdoctoral fellow at the University of Sydney and the University of California, Los Angeles.

Louk J. M. J. Vanderschuren is Associate Professor at the Ruldolf Magnus Institute of Neuroscience of the University Medical Center Utrecht in the Netherlands.
