Bilingual language production: The neurocognition of language representation and control

Despite an impressive psycholinguistic effort to explore the way in which two or more languages are represented and controlled, controversy surrounds both issues. We argue that problems of representation and control are intimately connected and we propose that data from functional neuroimaging may advance a resolution. Neuroimaging data, we argue, support the notion that the neural representation of a second language converges with the representation of that language learned as a first language and that language production in bilinguals is a dynamic process involving cortical and subcortical structures that make use of inhibition to resolve lexical competition and to select the intended language.
