title: Inhibiting your native language: the role of retrieval-induced forgetting during second-language acquisition.
abstract: After immersion in a foreign language, speakers often have difficulty retrieving native-language words--a phenomenon known as first-language attrition. We propose that first-language attrition arises in part from the suppression of native-language phonology during second-language use, and thus is a case of phonological retrieval-induced forgetting. In two experiments, we investigated this hypothesis by having native English speakers name visual objects in a language they were learning (Spanish). Repeatedly naming the objects in Spanish reduced the accessibility of the corresponding English words, as measured by an independent-probe test of inhibition. The results establish that the phonology of the words was inhibited, as access to the concepts underlying the presented objects was facilitated, not impaired. More asymmetry between English and Spanish fluency was associated with more inhibition for native-language words. This result supports the idea that inhibition plays a functional role in overcoming interference during the early stages of second-language acquisition.
