Bilingualism and biliteracy in Down syndrome: insights from a case study

We present the case study of MB – a bilingual child with Down syndrome (DS) who speaks Russian (first language, L1) and English (second language, L2) and has learned to read in two different alphabets with different symbol systems. We demonstrate that, in terms of oral language, MB is as proficient...

Description
Summary:We present the case study of MB – a bilingual child with Down syndrome (DS) who speaks Russian (first language, L1) and English (second language, L2) and has learned to read in two different alphabets with different symbol systems. We demonstrate that, in terms of oral language, MB is as proficient in Russian as English, with a mild advantage for reading in English, her language of formal instruction. MB’s L1 abilities were compared with those of 11 Russian-speaking typically-developing monolinguals; and her L2 abilities to those of 15 English-speaking typically-developing monolinguals and 6 monolingual English-speaking children with DS; each group achieving the same level of word reading ability as MB. We conclude that learning two languages in the presence of a learning difficulty need have no detrimental effect on either a child’s language or literacy development.
