摘要：Interference suppression (IS) is the ability to suppress irrelevant information. This process plays a key role whenbilinguals are required to speak one language, which requires inhibition of the non-target language. Previousresearch has evaluated linguistic and non-linguistic inhibition in bilingual and monolingual healthy adults,revealing a bilingual advantage on non-linguistic tasks (Costa et al., 2008; Luk et al., 2010). However an IS casestudy comparing healthy bilinguals, monolinguals and bilingual aphasic patients (BAs) contradicts theaforementioned studies (Green et al., 2010). No study has yet systematically examined IS in bilingual aphasia. Inthis study we investigate whether differences arise between healthy bilingual adults and BAs when completinglinguistic and non-linguistic tasks that require IS.
