Language exposure is an important determiner of language outcomes in bilingual children. Family language strategies (FLS, e.g., one-parent-one-language) were contrasted with parents' individual language use to predict language exposure in 4-31-month-old children (50% female) living in Montreal, Quebec. Two-hundred twenty one children (primarily…

This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of…

This study examines the influence of language environment on language and reading skills and the cross-linguistic contributions to reading outcomes in 132 Spanish-English bilingual children ages 7-12 (52% female; 98% Hispanic). We present three major findings: children's language knowledge is separable into general (e.g., phonological awareness)…

Individual differences in infants' native phonological development have been linked to the quantity and quality of infant-directed speech (IDS). The effects of parental and infant bilingualism on this relation in 131 five- and nine-month-old monolingual and bilingual Spanish and Basque infants (72 male; 59 female; from white middle-class…

Previous work indicates mutual exclusivity in word learning in monolingual, but not bilingual toddlers. We asked whether this difference indicates distinct conceptual biases, or instead reflects best-guess heuristic use in the absence of context. We altered word-learning contexts by manipulating whether a familiar- or unfamiliar-race speaker…

This study explored whether the directionality of the relation between majority language and various facets of socioemotional development (three to 5 years old) differs between children with different language backgrounds. 12,951 children (49% girls; 85% White, 6% Pakistani and Bangladeshi, 3% Black, 3% Mix, 2% Indian) from the British Millennium…

The study examined how children's self-regulation skills measured by the strengths and weaknesses of ADHD symptoms and normal behavior rating are associated with story comprehension and how verbal engagement and e-book discussion prompts moderate this relation. Children aged 3-7 (N = 111, 50% female, Chinese as first language) read an interactive…

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N = 283, 5-10 years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language…

We explored the ability of children to adapt their communication to the needs of their communication partner. Monolingual and bilingual 3-year-old children (N = 110) observed two puppets looking for puzzle pieces. One puppet showed its appreciation of the children's help, the other puppet wanted to solve the puzzle on its own. The children's…

This study investigated the influence of first language (L1) phonology on second language (L2) early reading skills in Sylheti-English bilinguals (N = 58; 48% girls; British Bangladeshi) and their monolingual-English peers (N = 43; 45% girls; 96% White British, 4% multiethnic British) in a diaspora context. Language-specific phonological awareness…

The susceptibility to gaze cueing in deaf children aged 7-14 years old (N = 16) was tested using a nonlinguistic task. Participants performed a peripheral shape-discrimination task, whereas uninformative central gaze cues validly or invalidly cued the location of the target. To assess the role of sign language experience and bilingualism in deaf…

Socioeconomic status (SES) and bilingualism have been shown to influence executive functioning during early childhood. Less is known, however, about how the two factors interact within an individual. By analyzing a nationally representative sample of approximately 18,200 children who were tracked from ages 5 to 7 across four waves, both higher SES…

Effects of child and environmental factors in moderating the course of bilingual development were investigated using longitudinal data, from age 2.5 to 5 years, on 126 U.S.-born children with early exposure to Spanish and English. Multilevel models of Spanish and English expressive vocabulary identified children's phonological memory ability as a…

This study investigated the vocabulary development of children (N = 547) from linguistically and socioeconomically diverse classrooms in Germany from age 3 in preschool to age 7 in Grade 1. The results showed that for dual language learners (DLLs, n = 107) growth rates in their German majority language skills varied over classrooms. Compared to…

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…
