In the previous 20 years, more than 60 studies have been carried out within the input and interaction approach to SLA (Long, 2007; Mackey 2012), many of which have found positive associations between different types of recasts and the learning of a range of linguistic forms for a number of different second languages (L2s), in different learning…

This paper presents an overview of what has come to be known as the "Interaction Hypothesis," the basic tenet of which is that through input and interaction with interlocutors, language learners have opportunities to notice differences between their own formulations of the target language and the language of their conversational…

In this article we report on a study undertaken with ESL children between 7 and 8 years old. They carried out communicative tasks in pairs in second language classrooms. We examined patterns of their task-based conversational interactions while we manipulated their familiarity with the procedure and content of the tasks. We found that learners…

In response to Ellis (2002), which focuses on frequency in language processing, language use, and language acquisition, this article argues in favor of a role for frequency in several areas of second language acquisition, including interactional input and output and speech processing. Also discusses areas where L2 acquisition appears to proceed…

Explored effects of interactional feedback on children's second language (L2) development in a prettest/posttest design. Child learners carried out communicative tasks that provided contexts for targeted forms and interactional feedback to occur. An experimental group received interactional feedback in response to non-targetlike production of…
