摘要：Current research on bilingual aphasia has only begun to inform us about the optimal rehabilitation for bilingual aphasie patients (Roberts & Kiran, 2007; Edmonds & Kiran, 2006) but the literature is still sparse in terms of interpreting the nature of naming impairments in bilingual aphasia We have developed a computational model to simulate a bilingual language system in which language representations can vary by age of acquisition and relative proficiency in the two languages. Based on recent theoretical models, a single semantic map is used, with separate maps for the words in the two languages, and six separate sets of connections between the maps. This model is subsequently lesioned at specific sites by varying connection strengths between the semantic and phonological networks.
