This paper proposes a number of refinements to the original theory of Exchange Structure as first conceived. It first offers a summary of the early ideas and considers challenges made by others. The study responds to these challenges through new analysis of multiparty discourse. The paper discusses revisions to the model based on these challenges drawing on the iterative analysis conducted and considers other points relevant to multiparty discourse. The data is drawn from transcribed video recordings of small groups of 4 to 5 year-old children’s peer-led dialogic interactions as they engage in role-play. In addition to the development of Exchange Structure theory, this new analysis sheds light on the nature of negotiation within multiparty discourse and the dynamics of negotiation by young children in this playful context.
