Bilingualism continues to increase with more than 350 different languages spoken in the United States, and more than 21% of people over the age of five (approximately 66 million people) speaking a language other than English at home (U.S. Census Bureau, 2020). Many bilingual children in the US speak a minority first language (L1) and English as…

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…

Numerous studies indicate that the language and literacy development of young children is highly contingent upon the construction of an enriching home literacy environment. Using sociocultural theory as a framework, in this article I explore how a bilingual child's language and literacy acquisition is embedded as a social practice within the home…

This article discusses the dynamic nature of childhood bilingualism by analyzing oral speech from returnee heritage speakers (HSs) of Portuguese, who grew up in Germany, but moved to Portugal in childhood/adolescence. The first dataset from 14 speakers showed that the length of exposure to German predicted the rate of (in)accurate production of…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

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…

Children from language minority homes reach school age with variable dual language skills. Cluster analysis identified four bilingual profiles among 126 U.S.-born, 5-year-old Spanish-English bilinguals. The profiles differed on two dimensions: language balance and total language knowledge. Balance varied primarily as a function of indicators of…

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…

Children and young people from migrated families often learn host languages faster than their parents might do, and from very young ages they help their parents, families or community members by translating or interpreting, known as child language brokering (CLB). Language brokers need to mediate with different languages in different contexts and…

This study investigates parent-teacher dialogues on child language learning as constructed in 19 interviews with migrant parents of Polish ethnolinguistic background, resettled in Norway and caring for young preschoolers and school-goers. Targeting reported speech as a linguistic resource for enacting agency in discourse, the focal interest is in…

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers' degree and experience, language usage, socioeconomic status) and internal factors (children's working memory, nonverbal intelligence, learning-related…

The linguistic interdependence hypothesis states that the development of skills in a second language (L2) partly depends on the skill level in the first language (L1). It has been suggested that the theory lacked attention for differential interdependence. In this study we test what we call the hypothesis of context-dependent linguistic…

Given that L1A of subject properties in non-null subject languages emerges later than that of null subject languages, this study aims at determining to what extent the same pattern of acquisition is observed in early child L2A in bilingual immersion settings where English and Spanish are both source and target languages. Using an elicited oral…

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…

When bilingual children enter formal reading education, host language proficiency becomes increasingly important. This study investigated the relation between socioeconomic status (SES), maternal language use, reading input, and vocabulary in a sample of 111 six-year-old children of first- and second-generation Turkish immigrant parents in the…
