摘要：Different psycholinguistic factors predict patterns of recovery in bilingual aphasia: language type, status (first or second language), dominance, and word type, e.g. word class, imageability, frequency, age of acquisition and cognate status (Weekes, 2010). Most studies report speakers of European languages that are similar in language type. We describe a Cantonese-Mandarin bilingual speaker with aphasia who is of interest because of linguistic differences between the two dialects. Although there is overlap in the lexical and morphological stmctures between Cantonese and Mandarin, syntactic and phonological properties of Cantonese and Mandarin are different. Our aim was to compare performance in each dialect of a Cantonese-Mandarin speaker by examining both lexical retrieval and discourse production, since word retrieval in bilingual aphasia does not always explain the recovery of free speech (Kambanaros, 2010). We expected differential patterns of performance in lexical naming and discourse production.
