Second language acquisition and linguistics: A bidirectional perspective
AbstractWe argue for a bidirectional relationship between second language research and linguistic theories. It is our belief that SLA research should look to linguistics for concepts and models that provide a basis upon which to make hypotheses, conduct data analysis, and draw conclusions, and we also believe that linguistic theorists can develop and improve their understanding of linguistic concepts and models by examining the results from SLA studies. In this paper, we present arguments in favor of this approach, with examples from two different types of linguistic universals: the Noun Phrase Accessibility Hierarchy and features such as tense and number. Second language acquisition data have been used to provide evidence for the Noun Phrase Accessibility Hierarchy and provide a way to understand areas in which its predictions are not met. Similarly, second language data provide us with a view of what happens when there is a contrast between features in a speaker’s native language and the language being learned. The data thus may shed light on the universality of features, in addition to how features are represented, parsed, and processed. In both cases, we argue that second language data are valuable when examining certain linguistic questions because they illuminate areas of conflict or mismatch between two linguistic systems.
