Research on Negotiation: What Does It Reveal About Second‐Language Learning Conditions, Processes, and Outcomes?

This article reviews insights into second‐language (L2) learning that have been revealed through over a decade of research on the social interaction and negotiation of L2 learners and their interlocutors, begining with the seminal work of Hatch (1978a, 197810) and Long (1980 et passim), and withereferenceto a corpus of informal, experimental, and classroom data from published studies. This research illustrates ways in which negotiation contributes to condi‐ tions, processes, and outcomes ofL2 learningby facilitating learners' comprehension and structural segmentation of L2 input, access to lexical form and meaning, and production of modified output. The research points out areas in which negotiation does not appear to assist L2 learning, especially with respect to the learner's need to access L2
