What is the function of emotional displays? We sit down with Thomas Ganzetti and discuss the role emotions serve in social contexts and how we use the displays of others to gather information about our realities. We chat about the evolutionary trajectory of emotional displays, how they help us navigate our environments, and what we learn about ourselves and those around us as we observe each other (whether we intend to or not).   Guest: Thomas Ganzetti Co-Host: Xueyi Yao (to hear more from Xueyi, check out Episode 18!)   Show notes on the monkey dance website!   Also, we've now been going for a full year! Thank you to everyone who has been listening and reaching out.
