Are animals capable of feeling joy? How do we know? What is joy? Dr. Erica Cartmill wants to find out. She's the Indiana University professor of cognitive science, animal behavior, and anthropology that long-time listeners to Stories of Impact will recognize from conversations we've had in the past about her studies of diverse intelligences and humor in apes. Today, we'll learn about one of her latest collaborative projects — a first of its kind multidisciplinary study: Joyful by Nature, on the evolution and the function of joy in animals. She's joined in conversation by Dr. Colin Allen, Professor of Philosophy at University of California Santa Barbara and Dr. Heidi Lyn, Joan M. Sinnott Professor in Ppsychology and Marine Sciences at the University of South Alabama. This team of expert researchers shares why it's both timely and important to move the science of animal emotion forward.
