In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

Code-switching is a common phenomenon in bilingual communities, but little is known about bilingual parents' code-switching when speaking to their infants. In a pre-registered study, we identified instances of code-switching in day-long at-home audio recordings of 21 French-English bilingual families in Montreal, Canada, who provided recordings…

Do parents fine-tune the MLU of utterances with a particular word as the word is on the verge of appearing in the child's production? We analyzed a corpus of spontaneous interactions of 30 dyads. The children were in the initial stages of their lexical development, and the parents' utterances containing the words the children eventually acquired…

To code-switch or not to code-switch? This is a dilemma for many bilingual language teachers. In this study, the influence of teachers' CS on bilingual children's language and cognitive development is explored within heritage language (HL) classes in Singapore. Specifically, the relationship between children's language output, vocabulary…

This study examines language mixing in 26 Spanish-English dual language learners over the course of their first year of preschool. The children's patterns of language choice while interacting in monolingual language contexts were analyzed at age 3;6 and 4;5 to examine: (1) whether the frequency of language mixing changed during the year; (2)…

Hearing words in sentences facilitates word recognition in monolingual children. Many children grow up receiving input in multiple languages -- including exposure to sentences that 'mix' the languages. We explored Spanish-English bilingual toddlers' (n = 24) ability to identify familiar words in three conditions: (i) single word…

We examined code-switching (CS) in the speech of twenty-four bilingual caregivers when speaking with their 18- to 24-month-old children. All parents CS at least once in a short play session, and some code-switched quite often (over 1/3 of utterances). This CS included both inter-sentential and intra-sentential switches, suggesting that at least…

This study examines pragmatic differentiation in early trilingual development through a longitudinal analysis of language choice in a developing Tagalog-Spanish-English trilingual child. The child's patterns of language choice with different language users are analyzed at age 1 ; 10 and 2 ; 4 to examine: (1) whether evidence for pragmatic…

This article concludes that language mixes do not constitute a major interference in the acquisition of bilingualism since children appear to be able to differentiate their two linguistic systems from an early age. (Author/NCR)

Examines the lexical and syntactic development of a bilingual child and the cognitive developments that coincided with the child's linguistic processes. Concludes that it is the development of self-awareness and sensitivity to standards in the second year which provides the motive for the child to avoid mixed-language utterances. (SED)

This study applies perspectives from sociolinguistics to investigate the language mixing of a bilingual two year old acquiring Norwegian and English simultaneously in Norway. The investigation stresses the need to examine more carefully the roles of dominance and context in the language mixing of young bilingual children. (40 references) (JL)

Examined language differentiation in bilingual toddlers prior to the emergence of functional categories. The children were observed with each parent separately and both together. Results indicate that while these children did code mix, they were able to differentiate between their two languages. There was some evidence that language dominance…

Investigates the relationship between a child's degree of bilingualism and features of parental input. Seeks to demonstrate that parental discourse strategies have a direct bearing on the levels of mixing present in a child's utterances in his weaker language (English). (Author/VWL)

The speech of 11-year-old children in different socioeconomic groups, was analyzed across a range of communicative tasks. On most "traditional" measures, consistent group differences did not appear. Significant differences were found on measures directly derived from the "planning principles" said by Bernstein to underlie restricted and elaborated…
