Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

Examining how bilingual infants experience their dual language input is important for understanding bilingual language acquisition. To assess these language experiences, researchers typically conduct language interviews with caregivers. However, little is known about the reliability of these parent reports in describing how bilingual children…

Bilingual infants must navigate the similarities and differences between their languages to achieve native proficiency in childhood. Bilinguals learning to find individual words in fluent speech face the possibility of conflicting cues to word boundaries across their languages. Despite this challenge, bilingual infants typically begin to segment…

Background: Bilingual children and children diagnosed with developmental language disorder (DLD) are characterized by reduced lexical-retrieval abilities. Few studies examined their joint contribution and the mechanisms underlying these effects in the lexical domain. Aims: To explore the joint effects of bilingualism and DLD by adopting a…

This study examined the developmental trajectories of Arabic grammatical number in Arabic-English bilingual children. The samples consisted of 80 individuals (40 monolingual children residing in Jordan and 40 bilingual children residing in the USA), aged between 5 and 9 years. Data was collected through two tasks involving picture able objects and…

Idiom comprehension and production reflect a child's language competence. Research suggests that there is a positive relationship between children's reading comprehension skills and their idiom understanding. This study examines whether adult verbal scaffolding, in conjunction with the deliberate use of iconic gestures, can facilitate young…

The article by Amaral and Roeper (this issue; henceforth A&R) presents many interesting ideas about first and second language acquisition as well as some experimental data convincingly illustrating the difference between production and comprehension. The article extends the concept of Universal Bilingualism proposed in Roeper (1999) to second…

Research using online comprehension measures with monolingual children shows that speed and accuracy of spoken word recognition are correlated with lexical development. Here we examined speech processing efficiency in relation to vocabulary development in bilingual children learning both Spanish and English (n=26 ; 2 ; 6). Between-language…

Research at the interface of bilingual development and child language disorders has increased greatly in the past decade. The purpose of this article is to highlight the theoretical and clinical implications of this research. Studies examining the similarities in linguistic characteristics between typically developing sequential bilingual children…

This paper investigates object omission in French longitudinal production from two English-speaking children (Lightbown, 1977). Similar patterns of object omission are observed: direct objects start being dropped as transitive verbs are emerging and licit and illicit null objects occur in all recordings thereafter. Moreover, the incidence of…

A comparison of the performance of age- and intelligence-matched bilingual (n=46) and monolingual (n=38) six- and seven-year olds on the Illinois Test of Psycholinguistic Abilities indicated that the bilinguals had significantly inferior performance in tests of the visual-motor channel, analogous auditory-vocal tests, and representative level. (18…

A study based on monthly recordings of one bilingual child exposed to English and German suggests that, contrary to earlier research, the acquisition of sociolinguistic rules appears to precede the acquisition of structural rules. The assumption that linguistic sophistication is necessary for children to understand that they are exposed to two…

This book concerns a neglected aspect of the education of bilingual children, namely, their potential desire and ability to learn to read before age 5. The basis of the study is considered in the chapter on children as early learners, which provides accounts of children being taught to read from the age of 6 months to 4 years. The next part of the…

This handbook provides an introduction to research findings related to bilingualism in minority-language children, and describes the implications of these findings for issues of current concern in Canadian education. Bilingualism is defined as the production and/or comprehension of two languages by the same individual. The phrase…

Results of a 10-item oral language test presented only orally, orally with pictures, and orally with concrete aids replicate earlier research findings showing that bilingual children manipulate language more easily than unilinguals. Unilinguals' errors were due to incomplete development while bilinguals' were caused by that and first-language…
