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…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

English is undoubtedly an important language for educational and socio-economic mobility in numerous countries including Malaysia. Regardless of its importance, studies to document English language acquisition among Malaysian children acquiring English in the local context remain scarce. This normative data is imperative for syllabus-designers,…

The present study investigated whether parent--child interactions during shared reading in a diverse sample of 91 three- to five-year-old dual language learners (DLLs) in Norway supported the development of the children's first (L1) and second language (L2) vocabulary skills. The dyads spoke 11 different L1s (i.e., Arabic, Polish, Somali, and…

Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the…

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages…

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 investigated bilingualism effects on the production of focus in 5- to 9-year-old Cantonese-English bilingual autistic children's L1 Cantonese, compared to their monolingual autistic peers as well as monolingual and bilingual typically developing children matched in nonverbal IQ, working memory, receptive vocabulary and maternal…

Recently, research in second language acquisition has seen an increased attention on low-educated low-literate (LESLLA) learners. However, few of the existing instruments to measure L2 proficiency have been validated for use with this population. In this paper, we examine how adult L2 learners with diverging educational backgrounds perform on and…
