Frequent L2 language use enhances executive control in bilinguals

Abstract

Seminal research which indicates that bilingualism leads to enhanced executive control (Bialystok, Craik, Green & Gollan, 2009; Bialystok, Craik & Luk, 2012) has recently been challenged (de Bruin, Treccani & Della Sala, 2014; Hilchey & Klein, 2011; Paap & Greenberg, 2013). We suggest that this discrepancy in findings is attributable to differences between bilinguals. Although the present results showed no significant differences in executive control between the monolinguals and bilinguals, those bilinguals who used their L2 more frequently in their daily lives were significantly more likely to evidence enhanced executive control over those who rarely used their L2.
