This study examines bilinguals’ ability to monitor for conflict and adjust behavior accordingly on tasks requiring cognitive control. The authors present the results of two experiments, where bilinguals’ and monolinguals’ behavioral performance and related neural activity were assessed during a neuropsychological activity such as a Stroop task. Findings revealed that, on the basis of trial history, monolinguals’ accuracy decreased after non-conflict trials, whereas bilinguals’ increased, showing a brain activity capable of greater conflict detection. This may suggest that bilinguals’ experience in resolving conflict between different languages affects the way in which their brain monitor for information conflict.
