The Interaction Hypothesis (IH) is attributed to Michael Long (1981) is based primarily on the work of Stephen Krashen and Evelyn Hatch. Long emphasized the importance of comprehensible input that was central to Krashen’s Input Hypothesis but claimed that this input was most likely to be acquired during interactions which involved discourse modifications. This claim supported that of Hatch (1978) who showed a direct link between the way learners acquired a second language (l2) and the interactions
