The Importance Of A Bilingual Advantage For Terms Of Enhanced Executive Control Essay

Good Essays
Bialystok, Craik, and Luk (2012) investigated the growing body of evidence examining the presence of a bilingual advantage in terms of enhanced executive control: the group of cognitive skills involved in language switching, working memory and inhibition. Furthermore, the researchers examined evidence supporting the notion that differences in brain structure and function helped to explain the bilingual advantage (Bialystok et al., 2012). In regards to joint activation in bilinguals, researchers found that both languages are always activated to some degree (Bialystok et al., 2012) Though this may cause language interference errors, bilinguals can select their target language with remarkable accuracy (Bialystok et al., 2012). Upon review of the literature, they found that bilinguals frequently utilized frontal systems (involved in executive control) to help manage attention to two language systems (Bialystok et al., 2012). In other words, whenever a bilingual said something, the executive control system was activated. To support this claim, fMRI research revealed that the activities in the frontal regions form neural networks in the brain that are unique to the bilingual’s experience of managing two independent language systems (Bialystok et al., 2012. In essence, the evidence supported the notion that bilinguals exercise the executive control system when they have to say something and, this over time, leads to modifications in the neural networks and anatomical structures of
