This book is about joint intelligence in action. It brings together scholarship in performance studies, cognitive science, sociology, literature, anthropology, psychology, architecture, philosophy and sport science to ask how tightly knit collaboration works. Contributors apply innovative methodologies to detailed case studies of martial arts, social interaction, freediving, site-specific artworks, Body Weather, human-AI music composition, Front-of-House at Shakespeare’s Globe, acrobatics and failing at handstands. In each investigation, performance and theory are mutually revealing, informative and captivating. Short chapters fall into thematic clusters exploring complex ecologies of skill, collaborative learning and the microstructure of embodied coordination, followed by commentaries from leading scholars in performance studies and cognitive science. Each contribution highlights unique features of the performance ecology, equipping performance makers, students and researchers with the theoretical, methodological and practical inspiration to delve deeper into their own embodied practices and critical thinking.
