ABSTRACT
Monolingual and bilingual young adults performed a task-switching experiment while EEG was recorded to investigate how bilingualism affects cognitive control following conflict. Participants were given pure blocks composed of three intermixed tasks, each consisting of univalent trials in which they responded to one feature of the stimulus - color, shape, or size. In the crucial conflict block, an irrelevant feature was added to one of the tasks, creating bivalent trials that included conflict. Behaviorally, all participants slowed responses to univalent trials that followed conflict, reflecting the post-conflict slowing effect. Electrophysiologically, monolinguals displayed longer-lasting post-conflict ERP effects and showed larger ERN amplitudes following responses than bilinguals, amplitudes that were associated with adjustments in response times. The interpretation is that bilinguals disengage attention following conflict from misleading stimuli or error responses more rapidly than do monolinguals.
