Puppies wrestling and mock-biting each other. Toddlers playing hide and seek. Kittens pouncing—repeatedly—on a toy mouse. You've no doubt looked on at scenes like this with amusement. And you've no doubt seen some of those viral videos—of ravens sledding down hills, of bumble bees playing with balls. All these moments make us smile, maybe even giggle. But the scientific questions they raise merit serious attention. Where do we see play in the animal kingdom? Where do we not? What functions does play serve? Do we—and many other creatures—have an elemental need for play?
My guest today is Dr. Gordon Burghardt. Gordon is a longtime Professor in the Department of Psychology and the Department of Ecology and Evolutionary Biology at the University of Tennessee. For decades now, Gordon has been a pioneer in the study of animal play, with a particular focus on play in reptiles and other animals not usually considered playful. His 2005 book, The Genesis of Animal Play, remains a landmark in the field.
Here, Gordon and I talk about the major types of play: locomotor play, object play, and social play. We discuss the five criteria he has proposed for recognizing play across animal taxa. We survey several of the functions of play that have been proposed over the decades, and discuss how—in the end—play doesn't seem to have just one function. We also talk about human play—about what sets it apart, and about the possibility that play lies at the root of many of the capacities and institutions we think of as distinctively, impressively human. Along the way, Gordon and I touch on play in bears, pythons, turtles, fruit flies, and octopuses. We consider play between members of taxonomically distant species. We talk about “self-handicapping”; the surplus resource theory of play; the importance of "risky play" and "free play"; the immersive quality of play; bodily and vocal play signals in mammals; and whether human play is increasingly endangered.
Without further ado, here's my conversation with Dr. Gordon Burghardt. Enjoy!
