The role of dual language exposure in children's cognitive development continues to be debated. The majority of the research with bilingual children in the US has been conducted with children becoming literate in onlyoneof their languages. Dual language learners who are becoming literate in both their languages are acutely understudied. We compared dual language learners (n = 61) in a Spanish–English dual language immersion program to monolingual English speaking children (n = 55) who were in a traditional English only school. Children (kindergarten to 3rdgrade) completed standardized vocabulary tasks and two measures of executive functions. Despite having significantly smaller English vocabularies, the dual language learners outperformed the monolingual children on the executive function measures. Implications for our understanding of the relations between oral language development and executive function in bilingual children are discussed.

Abstract The current study explores variation in phonemic representation among Spanish–English dual language learners (DLLs, n = 60) who were dominant in English or in Spanish. Children were given a phonetic discrimination task with speech sounds that: 1) occur in English and Spanish, 2) are exclusive to English, and 3) are exclusive to Russian, during Fall (age m = 57 months) and Spring (age m = 62 months, n = 42). In Fall, English-dominant DLLs discriminated more accurately than Spanish-dominant DLLs between English-Spanish phones and English-exclusive phones. Both groups discriminated Russian phones at or close to chance. In Spring, however, groups no longer differed in discriminating English-exclusive phones and both groups discriminated Russian phones above chance. Additionally, joint English-Spanish and English-exclusive phonetic discrimination predicted children's phonological awareness in both groups. Results demonstrate plasticity in early childhood through diverse language exposure and suggest that phonemic representation begins to emerge driven by lexical restructuring.

Some evidence suggests that the home numeracy environment (HNE) is related to children’s numeracy. Socioeconomic status (SES) and language minority status can also influence children’s HNE and numeracy. Limited HNE research focuses on dual language learners (DLLs). Using a sample of preschool-aged children ( n = 98) from low socioeconomic status (SES) backgrounds, we examined differences between Spanish-speaking DLLs’ ( n = 37) and monolingual English speakers’ ( n = 61) numeracy, differences in HNEs, and predictive role of HNE on numeracy. Using frequentist and Bayesian t tests, we found that numeracy was not significantly different between DLLs and monolingual English speakers when DLLs’ numeracy was measured in English or in both English and Spanish. However, DLLs’ Spanish numeracy was lower than monolingual English speakers’ English numeracy, t(96) = 2.10, p = .038, Bayes factors (BF10) = 1.51. HNE did not significantly predict either group’s numeracy regardless of assessment language. This study is an important step toward understanding DLLs’ HNE and numeracy.

Purpose Preschoolers' phonological awareness (PA) and alphabet knowledge (AK) skills are two of the strongest predictors of future reading. Despite evidence that providing at-risk preschoolers with timely emergent literacy interventions can prevent academic difficulties, there is a scarcity of research focusing on Latinx preschoolers who are dual language learners. Despite evidence of benefits of providing Latinxs with Spanish emergent literacy instruction, few studies include preschoolers. This study examined the effects of a supplemental Spanish PA and AK intervention on the dual emergent literacy skills of at-risk Latinx preschoolers. Method A multiple probe design across four units of instruction evaluated the effects of a Spanish supplemental emergent literacy intervention that explicitly facilitated generalizations to English. Four Latinx preschoolers with limited emergent literacy skills in Spanish and English participated in this study. Bilingual researchers delivered scripted lessons targeting PA and AK skills in individual or small groups for 12–17 weeks. Results Children made large gains as each PA skill was introduced into intervention and generalized the PA skills they learned from Spanish to English. They also improved their English initial sound identification skills, a phonemic awareness task, when instruction was delivered in Spanish but with English words. Children made small to moderate gains in their Spanish letter naming and letter–sound correspondence skills and in generalizing this knowledge to English. Conclusion These findings provide preliminary evidence Latinx preschoolers who are dual language learners benefit from emergent literacy instruction that promotes their bilingual and biliterate development.
