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…

This article uses cognitive measures previously developed within linguistic relativity research to explore the thinking patterns of Yucatec Maya-Spanish bilingual children in the Yucatan peninsula. These measures were designed to detect cognitive patterns associated with specific language patterns. Here, these measures are used to test whether 12…

This study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish…

In this study, the authors compare the production of internal codas and branching onsets in four groups of children learning French: monolingual typically-developing children (n = 12), bilingual typically-developing children (n = 61), monolingual children with Specific Language Impairment (n = 17) and bilingual children with Specific Language…

This qualitative, exploratory research study is positioned within the field of Family Language Policy (FLP). Contextualised in bilingual Malta, where Maltese is the majority language, the study inquires into the effects of a plurilingual family language programme on the language ideologies within English-speaking Maltese families. The programme…

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…

Polish and English differ in the surface realization of the underlying Determiner Phrase (DP): Polish lacks an article system, whereas English makes use of articles for both grammatical and pragmatic reasons. This difference has an impact on how referentiality is rendered in both languages. In this article, the authors investigate the use of…

Closely related Swedish and German both mark information status of referents morphologically, though little is known about its acquisition. This study investigates character introductions in the narratives of 4- and 6-year-old Swedish-German bilinguals (N = 40) in both languages, elicited with MAIN "Cat/Dog." We analyse effects of age…

This study examined play interactions of 15 to 48-month-old children (n = 59) and their caregivers in Lazuri, a UNESCO-rated endangered South-Caucasian ancestral language, and Turkish, a dominant language supplanting Lazuri usage in the community. Child-caregiver dyads played with two toy sets (animal farm and tea set) that provided different…

This study examines the role of agency in a young trilingual child's language choice in interaction with her Mandarin-speaking grandparents. The child was born in Japan to a Chinese mother and a Japanese father. English is used as a lingua franca in the family. The study demonstrates how the child asserts her agency to negotiate the decisions and…

This study explores typically developing bilingual children's performance in their English as a heritage language. The aim of this study is to advance our understanding of heritage language expectations and the role of chronological age and bilingual exposure. A broad range of receptive and expressive linguistic domains are investigated as a…

This longitudinal case study followed a Hebrew-speaking child acquiring L2-English, focusing on her production of articles. Although the child had already developed significant aspects of the Hebrew determiner system, her acquisition of English followed a typical developmental route for first language acquisition: single words; telegraphic speech;…

Heritage language (HL) speakers seem to diverge from monolingual speakers in the acquisition of syntax-discourse interface phenomena. However, most of the studies reporting this finding do not make any distinction between different types of syntax-discourse interface structures. Therefore, it is an open question whether these structures are…

Studies on L1- and L2-acquisition of German and Dutch have shown that the particles "too/also" and "again" hamper the realization of finiteness while the particle "not" promotes it. In this study the authors ask whether adversative "but" also affects the realization of finiteness. By applying a…

This study investigates the effects of early second-language (L2) acquisition on introduction of characters in narrative discourse by comparing 5- and 7-year-old monolingual (first-language [L1] = Turkish) and bilingual (L1 = Turkish, L2 = English) children. Turkish does not have a grammaticalized article system like English which enables to…
