Properties of child-directed speech in bilingual parents
A study on partial repetitions
How parents talk to young children matters to language and cognitive development. In the early years the quantity,
quality, and diversity inherent in language from parents in the home predict differences in vocabulary knowledge, school
readiness, and later academic achievement. However, most of what is known about child-directed speech (CDS) comes from studies of
monolingual parents, and little is known about features of speech from bilingual parents. Here, we asked whether degree of
bilingualism assessed within a single parent might be positively associated with CDS features that are known to facilitate
children’s lexical and grammatical structures across languages – parental partial repetitions. During unscripted narrations
(n = 91) of a picture book to their toddlers in English, mothers who reported being more bilingually balanced
used a higher proportion of self-repetitions (both single words and 2-word combinations) within a brief time-frame. At the same
time, more bilingual mothers preserved the same degree of lexical diversity as more monolingual mothers. The results obtained even
accounting for differences in socio-economic status. These findings are discussed in terms of adaptive strategies that bilingual
parents may consciously or unconsciously adopt in bilingual language development
