from Part IV - Individual Differences
Published online by Cambridge University Press: 25 June 2019
Learner age has for a long time featured prominently in the research agenda of the second language acquisition (SLA) field. Arguably, a few decades ago this agenda was almost exclusively dominated by the concern with constraints of age on post-puberty learners that originated in the Critical Period Hypothesis (CPH) as formulated by Lenneberg (1967) for first language (L1) acquisition. The CPH links age of onset or age of acquisition (AOA) to biological constraints on what can be attained beyond puberty, and it was extended to second language (L2) acquisition through the work of Johnson and Newport (1989). Participants in CPH studies typically came to be immigrants arriving to the L2 community at different ages and acquiring the community language to different degrees. In these studies, participants’ ultimate attainment is examined and compared on the basis of their age of arrival (usually equated with AOA), and a negative association is usually found between AOA and ultimate attainment. In Long’s (2005) words, the aim of this line of research is to provide “evidence for the existence, scope or timing of maturational constraints on the human capacity for learning second (including foreign) languages” (p. 288).
