摘要：
Bilingualism has been found to enhance the ability to store and manipulate information in working memory (WM). However, previous studies of WM function in bilingualism have been limited to behavioural measures, leaving questions unanswered regarding the effects of bilingualism on neural mechanisms employed during WM tasks. We recorded brain activity (event-related potentials; ERPs) while participants (23 English-speaking and 21 English-French bilinguals) performed an n-back WM task Accuracy and reaction time were similar across groups, but monolinguals exhibited smaller P300 amplitudes relative to bilinguals, suggesting that bilinguals have more cognitive resources available to complete cognitively demanding tasks.
