Bilingualism in children

Code-switching is a common feature of bilingual language use and has multiple factors that influence the frequency and type of code-switching. 56 Spanish-English bilingual children recorded sessions of Spanish-designated and English-designated interactions with a caregiver at 2.5 and 3.5 years. These sessions were transcribed and coded for all code-switched utterances. At both ages, we found: (1) Children switched to English more frequently than they switched to Spanish. (2) Their degree of English dominance was a positive predictor of their frequency of switching to English, but a negative predictor of their frequency of switching to Spanish. Between 2.5 and 3.5 years, children became more English dominant, and their rate of switching to English increased while their rate of switching to Spanish decreased. The present findings suggest that the strongest influence on bilingual children’s code-switching is their relative proficiency in their two languages and as that proficiency changes, their code-switching changes.

Extensive evidence indicates that oral language skills at school entry predict later reading development among monolingual children. It is not clear if the effect is the same for bilingually developing children and whether their oral skills in one language can transfer to reading comprehension in the other. The current longitudinal study followed 72 Spanish-English bilingual children (42 girls, 30 boys) and examined the extent to which early oral language proficiency in English and in Spanish were related to later reading comprehension development within- and across-languages. Multilevel models revealed significant within-language relations between oral language skills at 5 years and reading comprehension growth from 6 to 8 years in both English and Spanish. Additionally, English oral skill predicted Spanish reading comprehension, whereas Spanish oral skill was unrelated to English reading comprehension. Theoretical and practical implications of the findings are discussed.

This study examined the relation between home language exposure from different
household members, specifically older siblings, and English and Spanish vocabulary
development in bilingual toddlers. The English and Spanish vocabularies of 38 toddlers
(19 boys and 19 girls; Mage = 2.14 years, SD = .14) were measured. Parental EI?-glish use
was found to be the strongest predictor of English and Spanish proficiencies. Among
households in which the parents use less than 10% English, having older siblings had no
effect on English language proficiency but was associated with lower levels of Spanish
proficiency.

This study was designed to measure the relation of education and ethnic identity to attitudes towards bilingualism in two different ethnic groups, Asian and Latinos in the United States. In order to do this, an instrument was developed to measure attitudes towards bilingualism. No significant relations were found among education or ethnic identity and attitudes towards bilingualism in either group, but analyses revealed several other significant relationships. The two subscales of ethnic identity, MEIM-R Commitment and Exploration, were related to each other both within Asian and Latino groups and in all participants combined. In the combined sample, education levels of participants' mothers was correlated with the MEIM-R subscale of Exploration. In addition, participants with a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Commitment than participants with an Associates Degree or below. Participants with mothers who possess a Bachelors Degree or above were found to have significantly higher ethnic identity levels of MEIM-R Exploration than participants with mothers who possess an Associates Degree or below. Finally, Asian participants were found to have lower levels of MEIM-R Commitment when compared to Latino participants.

Many adults who have dual language experience describe themselves as "passive bilinguals," able to understand two languages, but speak only one. The aim of this study was to examine the relation between language production and comprehension in bilingual children in order to determine whether bilingual comprehension is more readily achieved than production. ... Productive and receptive skills in both languages were assessed using standardized tests. Children's relative amount of exposure to each language, as well as their language choice during production was measured via interview with the primary caregiver.... Language exposure as measured via dominance in one language over another appears to affect productive language differently than receptive language, further evidencing that language exposure is a significant predictor of acquisition that predicts production and comprehension differently. Additionally, when input is held constant, child language choice is uniquely related to productive and receptive language skill. The results of this study not only describe patterns of productive and receptive language skills and their correlates in young bilinguals, but they also address competing theories regarding the roles of input and output in the development of language comprehension and production.

The current study addressed several questions about the use of language intermingling in child-directed speech and its influence on children's English and Spanish language acquisition on children's language code-switching, Participants were 65 children (Mean age=30.93 months, SD=0.44, 28 boys and 37 girls) who had been exposed to English and Spanish from birth and for whom at least one parent was a native Spanish speaker.... Measures of the children's lexical, grammatical, receptive, and productive language development in English and in Spanish were collected concurrently.... Consistent with sociolinguistic theories that propose that language separation is necessary for heritage language maintenance, children who were exposed to more language intermingling were more English-dominant. Both sensitivity to the language context and children's language dominance were related to children's production of mixed utterances. Children code-switched more when speaking in their less proficient language and when in the context of minority language use.

This study investigated the effects of family composition and properties of children's dual language exposure on bilingual first language acquisition. Mothers of 29 toddlers (13 boys and 16 girls, M age = 25.66 months, SD = .44) kept a language diary, providing measures of the amount, the contexts, and the persons with whom the children experienced English and Spanish. Measures of the children's vocabulary balance were obtained from English and Spanish language inventories. Results showed that only children with two native Spanish-speaking parents had larger Spanish than English vocabularies and experienced more hours of Spanish-only exposure and Spanish-only conversational contexts. Analysis of covariance demonstrated that the effect of family composition on vocabulary balance was completely mediated by the balance of English and Spanish in the children's language exposure. There was no evidence of a unique effect of experiencing Spanish-only conversational contexts or partners on children's acquisition of Spanish.
