This paper explores whether English-Mandarin bilingual children have mastered discourse skills and whether they show sensitivity to the discourse principle of information status of referents in their speech and gestures. We compare the speech and gestures produced by bilingual children to those produced by English- and Mandarin-speaking…

This study investigates constraints on ultimate attainment in second language (L2) pronunciation in a direct comparison of perceived foreign accent of 40 late L2 learners and 40 late first language (L1) attriters of German. Both groups were compared with 20 predominantly monolingual controls. Contrasting participants who acquired the target…

This paper investigates how learners interpret definite plural noun phrases (e.g., "the tigers") and bare (article-less) plural noun phrases (e.g., "tigers") in their second language. Whereas Spanish allows definite plurals to have both generic and specific readings, English requires definite plurals to have specific, nongeneric readings. Generic…

Previous studies have shown that preschool bilingual children lag behind same-aged monolinguals in their production of correct past tense forms. This lag has been attributed to bilinguals' less frequent exposure to either language. If so, bilingual children acquire the past tense like monolinguals, only later. In this study, we compared the…

This study examined the effects of first language characteristics on the development of two aspects of English morphological awareness: derivational and compound awareness in English language learners (ELLs) with Chinese or Spanish as their first language. It also assessed the contribution of derivational and compound awareness to word reading in…

The present study examined the growth of receptive lexical skills in preschoolers over an academic year in relation to teacher speech. The participating students were English language learners and their monolingual English-speaking peers from the same classrooms. The measures of teacher input included indicators of the amount of speech (total…

I commend Johanne Paradis not only for her interesting Keynote Article but also for the careful research that she has conducted along with her collaborators in the area of bilingual language development and disorders. Her contributions have been significant and are sure to shape our theoretical as well as clinical understanding of specific…

Joanne Paradis' Keynote Article on bilingualism and specific language impairment (SLI) is an impressive overview of research in language acquisition and language impairment. Studying different populations is crucial both for theorizing about language acquisition mechanisms, and for practical purposes of diagnosing and supporting children with…

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…

What makes a child's language development trajectory have the patterns that it has, and what causes differences across children in those patterns? These fundamental questions have for over half a century been at the heart of research on language development in monolingual children, on the cross-linguistic development of language in children from…

Research in monolingual populations indicate that vocabulary knowledge is essential to reading achievement, but how vocabulary develops in bilingual children has been understudied. The current study investigated the role of home and school factors in predicting English vocabulary among 284 bilingual kindergartners (168 Chinese, 65 Malay, 51…

This study reports on a comparison of the use and knowledge of tense-marking morphemes in English by first language (L1), second language (L2), and specific language impairment (SLI) children. The objective of our research was to ascertain whether the L2 children's tense acquisition patterns were similar or dissimilar to those of the L1 and SLI…

This study investigated the relationships between home language learning activities and vocabulary in a sample of monolingual native Dutch (n = 58) and bilingual immigrant Moroccan-Dutch (n = 46) and Turkish-Dutch (n = 55) 3-year-olds, speaking Tarifit-Berber, a nonscripted language, and Turkish as their first language (L1), respectively. Despite…

Past research demonstrates that first language (L1)-like competence in each language can be attained in simultaneous acquisition of bilingualism by mere exposure to the target languages. The question is whether this is also true for the "weaker" language (WL). The WL hypothesis claims that the WL differs fundamentally from monolingual L1 and…

The development of native language phonetic representations in bilingual infants was compared to that of monolingual infants. Infants (ages 6-8, 10-12, and 14-20 months) from English-French or English-only environments were tested on their ability to discriminate a French and an English voice onset time distinction. Although 6- to 8-month-olds…
