This edited book revisits the concept of social 'activities' from an interactional perspective, examining how verbal, vocal, visual-spatial and material resources are deployed by participants for meaning-making in social encounters. The eleven original chapters within this volume analyse activities based on video recordings of naturalistic and naturally occurring social encounters from face-to-face and mediated settings in Chinese, Dutch, English, French, and German. Informed primarily by the methodological approaches of Conversation Analysis and Interactional Linguistics, the authors study embodiment in space and time in three distinct types of situations: objects in space, complex participation frameworks, and affiliation and alignment. Moreover, the book includes a theoretical and methodological discussion of how activities are constituted and visibly embodied in interaction. It will be of interest to students and scholars in sociology and linguistics in general, and face-to-face and mediated interaction in particular.
