Brain Basis of Bilingualism
In this line of research we aim at advancing in our knowledge of how the brain handles two languages. We pay especial attention to the processes involved in language control during speech production. We use both behavioral and neuroscience methods to elucidate how bilinguals manage to produce speech in one of their languages while preventing massive interference from their other language.
This project aims at testing to which extent bilingual language control mechanisms are subsidiary to those of the general-domain executive control. We use different tasks supposed to involve bilingual language control (language switching, Stroop-like) and other non-linguistic tasks involving executive control (task switching, flanker task). We then compare the performances of all tasks in the same populations of bilingual in order to gather information about the cross-talk between the two domains, such as linguistic and non-linguistic ones.
