Abstract

Current research on bilingual aphasia has only begun to inform us about optimal rehabilitation but the literature is sparse in terms of interpreting the nature of naming impairments in bilingual aphasia. The goal of the present study is to build a model that can simulate language impairments and rehabilitation in patients with bilingual aphasia. Specifically, the model takes into account Age of Acquisition (AoA) and pre-stroke language use in the two languages. This model is subsequently lesioned at specific sites and then rehabilitated in one language (e.g., either English or Spanish) and the extent of cross language transfer is examined.
