Dog or chien? Translation equivalents in the receptive and expressive vocabularies of young French-English bilinguals

Double it up: Vocabulary size comparisons between UK bilingual and monolingual toddlers

We compared vocabulary sizes in comprehension and production between bilingual toddlers growing up in the United Kingdom (UK) and age-matched UK English monolinguals (12-36 months old) using parent-report vocabulary questionnaires. We found that bilingual toddlers' vocabulary sizes in English were smaller than the vocabulary sizes of their monolingual peers. Notably, this vocabulary gap was not found when groups were compared on conceptual vocabulary in comprehension. Conceptual scoring also reduced the vocabulary gap in production but group differences were still significant. Bilingual toddlers knew more words than monolinguals when words across their two languages were added together, for both comprehension and production. This large total vocabulary size could be attributed to a high proportion of doublets (cross-linguistic word pairs with the same meaning) in bilinguals' vocabularies. These findings are discussed in relation to language exposure, facilitation from cross-linguistic overlap and maturation constraints on vocabulary size.

Assessment of Language Development in Dual Language Learners: A Case Report

Propelled by immigration, language diversity is increasing in the United States, and more young children are exposed to two or more languages at home from birth. Known as dual language learners (DLLs), the benefits of this exposure include multilingual and multiliterate outcomes. However, DLLs introduce complexity for the pediatric provider's assessment of language development, identification of potential language delays, and timely referrals. If language delays are not promptly identified and followed with early intervention, they can persist and lead to poor outcomes across multiple domains.

Learning graphic symbols in two languages: Effects of monolingual teaching

PURPOSE

Limited research exists to guide augmentative and alternative communication (AAC) intervention for children from multilingual backgrounds. When a graphic symbol-based AAC system is provided to children, they need to learn the meaning of the graphic symbols. This study determined the effect of teaching the association between a graphic symbol and a spoken word in one language on the ability of bilingual children without disabilities to transfer this learning to their second language.

METHOD

A one-group pre-test-post-test design was used. The ability of 30 English-Afrikaans bilingual children aged 4-5 years to provide the spoken words associated with nine graphic symbols in English and Afrikaans was evaluated before and after teaching them the symbol-word associations in English.

RESULT

Correct symbol-word associations in English increased from a median of 0-9 post-teaching, while correct symbol-word associations in Afrikaans increased from a median of 0-6. A moderate positive relationship was identified between children's performance on symbol-word associations in Afrikaans during the post-test and their use of Afrikaans in the home.

CONCLUSION

Results suggest the presence of positive transference of graphic symbol-word associations learnt in one language to another known language. The implications of this finding on the provision of multilingual AAC intervention are discussed.

Vocabulary production in toddlers from low-income immigrant families: evidence from children exposed to Romanian-Italian and Nigerian English-Italian

The relationship between first and second language in early vocabulary acquisition in bilingual children is still debated in the literature. This study compared the expressive vocabulary of 39 equivalently low-SES two-year-old bilingual children from immigrant families with different heritage languages (Romanian vs. Nigerian English) and the same majority language (Italian). Vocabulary size, vocabulary composition and translation equivalents (TEs) were assessed using the Italian/L1 versions of the CDI. Higher vocabulary in Italian than in the heritage language emerged in both groups. Moreover, Romanian-Italian-speaking children produced higher proportions of TEs than Nigerian English-Italian-speaking children, suggesting that L1-L2 phonological similarity facilitates the acquisition of cross-linguistic synonyms.

Relations between phonological production, grammar and the lexicon in bilingual French-English children

AIMS AND OBJECTIVES

This study examines multiple associations between language domains in bilingual children with a focus on phonology. Previous studies indicate within- but not cross-language associations between vocabulary and grammar in bilingual children. We investigate whether the relation between phonology and other language domains differs from the one reported between vocabulary and grammar.

METHODOLOGY

Canadian French-English bilingual children (n = 31), aged 31 months, participated in 2 free-play sessions, from which lexical, grammatical and phonological information was extracted. The children's parents completed the MacArthur-Bates Communicative Developmental Inventories and its Canadian French adaptation providing additional information on vocabulary and grammar in each of the children's languages. They also completed a questionnaire on their children's exposure to French and English.

DATA ANALYSIS

Within and cross-language relations between phonology, vocabulary and grammar were investigated using correlational analyses and mixed logistic regression.

FINDINGS

Correlational analyses did not reveal significant cross-language relations between phonology, vocabulary and grammar. However, mixed logistic regression, which controlled for language exposure effects, indicated that phonology was influenced by vocabulary and grammar both within and across languages.

ORIGINALITY

This study is one of the first to study cross-domain relations involving phonology in young bilingual children.

IMPLICATIONS

Overall, the findings suggest that phonology displays a pattern of relations that is different from other language domains engendering between-language effects due to a language-general component.

Labels or Concepts? The Development of Semantic Networks in Bilingual Two-Year-Olds

The adult lexicon links concepts and labels with related meanings (e.g., dog-cat). How do children's encounters with concepts versus labels contribute to semantic development? Three studies investigated semantic priming in 40 monolinguals and 32 bilinguals, who have similar experience with concepts but different experience with labels (i.e., monolinguals hear "dog," bilinguals hear "dog" and "chien"). Similarities in performance across monolinguals and bilinguals at age 24 months, as well as across bilinguals' two languages at age 30 months, support the position that encounters with concepts contribute more to early semantic development than encounters with labels. Findings also suggest that the effects of semantic priming are challenging to observe at 24 months but are strong in bilinguals by age 30 months.
