Abstract
This article aims to explicate the concept of emotional sharing against the background of interactive and situated approaches to affectivity, and to contextualize emotional sharing within the broader context of emotion research. It brings together research on situated affectivity with the debate on collective emotion. Emotional sharing is defined via four requirements and distinguished from other phenomena in the broad field of collective emotion, especially from mechanisms of emotional convergence and other forms of affective we-experience. The paper makes use of the recently proposed concepts of affective scaffolding and affective arrangement to explore how emotional sharing is always enacted in sociorelational dynamics and embedded in socio-material contexts which enable, shape, and modulate the unfolding of emotional sharing and regulate who is likely to participate.
