An advantage for bilingual relative to monolingual young adults has been found for cognitive control tasks, although this finding is not consistent in the literatuie. The present investigation further examined this advantage using three tasks previously found to be sensitive to the effect. Furthermore, both behavioral and event-related brain potential (ERP) measures were included. Monolingual (n=25) and highly proficient bilingual (n=26) young adults completed a Stroop, Simon, and Eriksen flanker task while electrophysiological recording took place. Behaviorally there were no language group differences on any of the tasks. The ERP measures demonstrated differences between monolinguals and bilinguals with respect to conflict monitoring, resource allocation, stimulus categorization, and error-processing; however, these differences were not consistent across tasks. Given the similar behavioral performance across the groups the observed differences in brair. responses may not represent an advantage for bilinguals. The results are discussed with respect to previous findings. (C) 2012 Elsevier B.V. All rights reserved.
