second-language (l2) acquisition is generally thought to be constrained by maturational factors that circumscribe a critical period for native-like attainment. consistent with the maturational view are age effects among learners who begin l2 acquisition prior to, but not after, closure of the putative critical period. some studies indicate that native-like acquisition of a second language by le...

doing a piece of research on acquisition of second language phonetics theoretically will justify the exact stages of language trans- fer and further predicts the existence of systematicity and difficulty order (eckman, 2008). the present research is an attempt to provide new evidence for the efficacy of second language acquisition to devel- opmental stages of acquisition of phonological structu...
