This review critically explores one controversial issue in SLA: the Critical Period Hypothesis which advocates "a specific and limited time period for language acquisition"(Lightbown and Spada, 1999, p.19). Many studies investigating the relationship between age of onset and second language development have concluded that puberty is a turning point in language learning and that after this period achievement of native-like proficiency especially in phonological features can only occur with difficulty. Conversely, a number of studies have successfully shown that postpuberty learners have achieved native-like mastery of their respective target language. In this article I outline four principal studies weighing against the Critical Period Hypothesis and examine whether it is possible to attain native-like competence in SLA after this "critical period." I demonstrate that individual variables such as training, instruction, L1-L2 correspondence and motivation are clearly influential factors in language learning besides age.
