The Routledge International Handbook of Interactionismdemonstrates the promise and diversity of the interactionist perspective in social science today, providing students and practitioners with an overview of the impressive developments in interactionist theory, methods and research. Thematically organized, it explores the history of interactionism and the contemporary state of the field, considering the ways in which scholars approach topics that are central to interactionism. As such, it presents discussions of self, identity, gender and sexuality, race, emotions, social organization, media and the internet, and social problems. With attention to new developments in methods and methodologies, including digital ethnography, visual methods and research ethics, the authors also engage with new areas of investigation that have emerged in light of current societal developments, such as policing and police violence, interactionism beyond binaries and social media. Providing a comprehensive overview of the current state and possible future of interactionist research, it will appeal to interactionist scholars, as well as to established sociologists and students of sociology who have an interest in latest developments in interactionism.
