Domain-general cognitive control and domain-specific language control in bilingual aphasia: A systematic quantitative literature review

For successful language production in a target language, bilingual individuals with aphasia must inhibit interference from the non-target language. It is currently unknown if inhibition of involves general cognitive control (domain-general control) or whether it specific to linguistic mechanisms (domain-specific during production. The primary aim this systematic quantitative literature review was identify and synthesize available evidence, relation bilinguals aphasia, for these two mechanisms. We conducted search across five databases using set inclusion/exclusion criteria designed review. extracted data twenty studies reporting original research aphasia. results provided evidence both domain-general domain-specific mechanisms, although most showed involvement control. Available neuroimaging indicated that neural regions involved were anterior cingulate cortex, caudate nucleus, basal ganglia, frontal lobe. Theoretical implications inhibitory model, clinical assessment treatment abilities as well need future are discussed.
