Near native-like stress pattern perception in English-French bilinguals as indexed by the mismatch negativity

Abstract

We examined lexical stress processing in English-French bilinguals. Auditory mismatch negativity (MMN) responses were recorded in response to English and French pseudowords, whose primary stress occurred either on a language-consistent "usual" or language-inconsistent "unusual" syllable. In most conditions, the pseudowords elicited two consecutive MMNs, and somewhat surprisingly, these MMNs were not systematically modulated by bilingual experience. This suggests that it is possible to achieve native-like pre-attentive processing of lexical stress, even in a language that one has not learned since birth.
