The accessibility of Universal Grammar in adult language learning

Abstract
This paper investigates whether Universal Grammar (UG) is accessible to adult language learners. If adult acquirers have consistent access to intuitions of grammaticality in cases where the relevant constraints are underdetermined by the native language, this suggests that Universal Grammar continues to function in adult acquisition. Advanced Korean adult acquirers of English were given a test of grammaticality judgements on English wh-movement sentences, where the relevant constraints are thought to derive from principles of UG. Since Korean does not have syntactic wh-movement, correct intuitions cannot derive from native language transfer. Analysis of the results and comparison with native speaker results suggests a complex picture of the function of UG in adult language acquisition; however, clear UG effects were found.
