Vocabulary size is a crucial early indicator of language development, for both monolingual and bilingual children. Assessing vocabulary in bilingual children is complex because they learn words in two languages, and there remains significant controversy about how to best measure their vocabulary size, especially in relation to monolinguals. This…

Purpose: To avoid misdiagnosis with developmental language disorder (DLD) in bilingual children, it is recommended to evaluate both languages. However, unlike their monolingual peers, bilingual children acquire their heritage language under adverse input conditions. Focusing on Levantine Arabic, the study evaluates the clinical utility of a…

In bilingual children, more so than in monolingual children, comprehension abilities exceed production abilities. While this receptive-expressive gap in bilinguals has been well documented, little is known about its development. The present study tracked growth in the Spanish and English receptive and expressive vocabularies of 52 bilingual…

Purpose: Despite the increasing population of dual language learners (DLLs) in the United States, vocabulary measures for young DLLs have largely relied on instruments developed for monolinguals. The multistudy project reports on the psychometric properties of the English--Spanish Vocabulary Inventory (ESVI), which was designed to capture unique…

Purpose: Cognates, words in two languages that share form and meaning, can be used to support vocabulary development in bilingual children. Typically developing bilinguals have shown better performance on cognates versus noncognates. Of key interest is whether bilinguals with developmental language disorder (DLD) also show a cognate effect and, if…

Background: Early detection and remediation of language disorders are important in helping children to establish appropriate communicative and social behaviour and acquire additional information about the world through the use of language. In the Netherlands, children with (a suspicion of) language disorders are referred to speech and hearing…

Assessing vocabulary knowledge is an important part of establishing language proficiency in bilingual children. The crosslinguistic lexical tasks (CLTs) provide a framework for testing vocabulary development in three-to-six year-olds using a standard procedure and comparable items for multiple languages. This study describes the development of the…

Children with Down syndrome (DS) present language deficits in all linguistic domains and their language development lags behind that of typically developing children. However, their receptive language skills appear to be better than their productive in all linguistic domains. Research on bilingual children with DS is limited, but has shown that…

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are…

This study evaluates the ability of different measures of socioeconomic status (SES) to predict lexical outcomes for preschoolers raised in a context of nationwide bilingualism. The participants were 58 children aged 3;11-4;3 from Maltese-dominant homes who attended state preschools. Receptive picture name judgement and picture naming, in Maltese…

An experimental crossover research design was utilized to investigate the effects of multimedia-enhanced instruction on the vocabulary acquisition of dual language learners in the early childhood age range. Sixteen 3-year-olds stratified by classroom and randomly assigned to condition participated in an eight-week intervention that incorporated…

This study examined the effects of older siblings' L1/L2 use on the vocabulary and fast mapping skills in preschool-age children who learn Cantonese (L1) as a home language and start to learn English (L2) in preschool settings. Two groups of bilingual children participated in this study: (1) children whose older siblings used mostly L1 at home…

Efficient visual exploration in infancy is essential for cognitive and language development. It allows infants to participate in social interactions by attending to faces and learning about objects of interest. Visual scanning of scenes depends on a number of factors, and early differences in efficiency are likely contributing to differences in…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

There can be significant diversity in the language experience of minority language children, and in the levels of proficiency reached. The declining numbers of children now exposed to Irish include those from homes where only/mainly Irish is spoken, those with only one Irish-speaking parent, and children from homes where one/both parent(s) speak…
