The use of a second language enhances the neural efficiency of inhibitory control: An ERP study

Abstract This study investigated how natural language use influences inhibition in language-unbalanced bilinguals. We experimentally induced patterns of (as proposed by the Adaptive Control Hypothesis) and assessed their cognitive after-effects a group 32 Polish–English Each participant took part series three games involving real conversation. game was followed two tasks (stop-signal task Stroop task). The manipulation form did not affect behavioural measures, but it ERPs. Performance accompanied reduction P3 N450 amplitude differences after L2. ERP modulations suggest that for bilinguals living an L1 context L2 enhances neural mechanisms related to inhibition. provides first evidence direct influence on
