Language development in deaf bilinguals: Deaf middle school students co-activate written English and American Sign Language during lexical processing
COGNITION(2021)
Abstract
Bilinguals, both hearing and deaf, activate multiple languages simultaneously even in contexts that require only one language. To date, the point in development at which bilingual signers experience cross-language activation of a signed and a spoken language remains unknown. We investigated the processing of written words by ASLEnglish bilingual deaf middle school students. Deaf bilinguals were faster to respond to English word pairs with phonologically related translations in ASL than to English word pairs with unrelated translations, but no difference was found for hearing controls with no knowledge of ASL. The results indicate that co-activation of signs and written words is not the outcome of years of bilingual experience, but instead characterizes bilingual language development.
