This study investigates perception and production of the Catalan mid-vowel /e/-/[epsilon]/ contrast by two groups of 4.5-year-old Catalan-Spanish bilingual children, differing in language dominance. Perception was assessed with an XAB discrimination task involving familiar words and non-words. Production accuracy was measured using a familiar-word…

This project explores how the variation in language experiences and attitudes that Mexican American Spanish heritage speaker bilinguals in the United States have affects their speech perception in both their languages. Heritage language bilinguals speak as a first language a minority language that they have cultural ties to (e.g., Spanish in the…

Purpose: This report compares device use in a cohort of Spanish-English bilingual and English monolingual children who are deaf and hard of hearing, including children fitted with traditional hearing aids, cochlear implants (CIs), and/or bone-conduction hearing devices. Method: Participants were 84 Spanish-English bilingual children and 85 English…

Codeswitching has been used as a tool to investigate how the properties of the two language systems interact in the bilingual mind with relatively few studies investigating bilingual children. We target two groups of L1-Spanish-L2-English children in Spain to address language activation and language inhibition in the processing of codeswitching…

Little systematic attention has been paid toward belonging for young children, particularly in contexts of diversity that are regularly part of school settings. Two-Way immersion (TWI) programs provide one educational context ideally suited for exploring the constructs of belonging and inclusion in linguistically and culturally diverse settings.…

Naturalistic, Developmental, and Behavioral Interventions (NDBIs) are an empirically supported intervention approach for young autistic children and their families. Spanish-speaking (SS) Latinx families have been underrepresented in autism intervention research, limiting our understanding of whether NDBIs are aligned with Latinx family values and…

Purpose: Traditional approaches to studying bilingual language development through bilingual-monolingual comparisons are deeply flawed. They are also insufficient as the evidence base for informing advice to bilingual parents regarding the optimal bilingual exposure strategy and for supporting the formulation of bilingual intervention approaches.…

Despite a rapid growth in the number of dual language learning children (DLLs) in the United States, there is a limited understanding of what parents of DLLs believe and know about dual language learning and education, and how parental beliefs and knowledge relate to children's dual language experiences at home. In the current study, 225 parents…

Language learning is influenced by both neural development and environmental experiences. This work investigates the influence of early bilingual experience on the neural mechanisms underlying speech processing in 4-month-old infants. We study how an early environmental factor such as bilingualism interacts with neural development by comparing…

Core vocabulary lists and vocabulary inventories vary according to language. Lists from one language cannot and should not be assumed to be translatable, as words represent language-specific concepts and grammar. In this manuscript, we (a) present the results of a vocabulary overlap analysis between different published core vocabulary lists in…

Code-switching (switching between languages) is a common linguistic behavior in bilingual speech directed to infants and children. In adult-directed speech (ADS), acoustic-phonetic properties of one language may transfer to the other language close to a code-switch point; for example, English stop consonants may be more Spanish-like near a switch.…

With the rise of bilinguals globally, extensive research has been conducted to understand how bilingualism affects cognitive functions differently from monolingualism, with significant implications for bilingual education, healthcare, and other fields. Specific to language processing, differences have been identified between second language (L2)…

Emergent bi/multilingual children have historically been afforded few opportunities to engage dialogically with peers and teachers in posing authentic questions and co-constructing interpretations of texts as their reading instruction has traditionally been skills driven. Additionally, more recent scholarship has identified increased opportunities…

In a phenomenon known as translanguaging, multilingual learners draw freely from their repertoires without regard for language boundaries. Although multilingual learners live their lives between languages in their communities, science education is just beginning to acknowledge the important role of their hybrid language practices for learning.…

Research on the effects on early bilingualism on reading development is scarce. Here, we tackle this question by investigating whether the exposure to dual-language contexts (use of two languages in the same conversational situation) induces a boost in phonological and reading performance through more balanced spatial auditory attentional skills.…
