Vocabulary, Metalinguistic Awareness and Language Dominance Among Bilingual Preschool Children.

Awareness of language structure has been studied in bilinguals, but there is limited research on how language dominance is related to metalinguistic awareness, and whether metalinguistic awareness predicts vocabulary size. The present study aims to explore the role of language dominance in the relation between vocabulary size in both languages of bilingual children and metalinguistic awareness in the societal language. It evaluates the impact of two metalinguistic awareness abilities, morphological and lexical awareness, on receptive and expressive vocabulary size.

Quantitative and qualitative differences in the lexical knowledge of monolingual and bilingual children on the LITMUS-CLT task.

While bilingual children follow the same milestones of language acquisition as monolingual children do in learning the syntactic patterns of their second language (L2), their vocabulary size in L2 often lags behind compared to monolinguals. The present study explores the comprehension and production of nouns and verbs in Hebrew, by two groups of 5- to 6-year olds with typical language development: monolingual Hebrew speakers (N = 26), and Russian-Hebrew bilinguals (N = 27). Analyses not only show quantitative gaps between comprehension and production and between nouns and verbs, with a bilingual effect in both, but also a qualitative difference between monolinguals and bilinguals in their production errors: monolinguals' errors reveal knowledge of the language rules despite temporary access difficulties, while bilinguals' errors reflect gaps in their knowledge of Hebrew (L2).
