A significant interest in improvisation has emerged within the humanities in recent decades. Various factors have played a role in this changing landscape: the dissemination of notions gained from performance studies, comparative approaches to world cultures, the observation of the role of the body and emotions in cognitive processes, and the real-time models of interaction stimulated by new media.  This section hosts materials and articles which consider improvisation in an interdisciplinary perspective. The essays draw on the current discussion and elaborate patterns for the understanding of different historical periods. A think tank is dedicated to the notions of subjectivity and interaction.
