Chapter 8. A calculus for L1 transfer

Abstract

The phenomenon of transfer plays a prominent role, either explicitly or implicitly, in most approaches to SLA, including Focus on Form and the Interaction Hypothesis – to name two lines of inquiry that lay at the heart of Mike Long’s scholarship. The central thesis of this chapter is that transfer is best seen as a processing-driven strategy: L2 learners transfer operations from their L1 to the L2, unless those operations are more costly in the L2 than in the L1. Much of the chapter is devoted to the application of this idea to phenomena that arise when adult native speakers of English, Japanese, Korean, Spanish and Catalan go about acquiring a second or third language, producing transfer effects that have been difficult to accommodate in traditional approaches to cross-linguistic influence.
