Decades of research have demonstrated that parenting programs are effective at changing parent behaviors and subsequently preventing myriad child outcomes including anxiety, depression, substance use, and HIV infection. However, most research into preventive parenting interventions in the United States has been conducted with English-speaking…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

Multitiered systems of support hold promise for dual language learners when culturally and linguistically responsive practices guide instruction. We modeled growth on Spanish and English early literacy skills and examined the role of language exposure and use at the individual and classroom instruction level in a group of 313…

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…

We modeled growth on Spanish and English early literacy skills and examined the role of language exposure and use at the individual and classroom instruction level in a group of 313…

Migrant communities settle and appropriate spaces in their new home through deterritorialisation and reterritorialisation processes, which involve the reconceptualisation of the language and symbols of the homeland and those spoken and used in the diaspora. The public sphere is one of the most distinguishable places where this contextual relation…

Drawing on positioning theory and Vygotsky's sociocultural theory of mind, this study analyzes the discursive processes through which expert and novice positions are negotiated in heritage-second language (HL-L2) learner interaction. It examines how positioning practices shape collaboration between HL and L2 learners, determining what types of…

Emergent bilinguals (EB) from Spanish-speaking homes are an already large and rapidly growing population in the U.S., yet limited research examines their language environments, particularly in the English dominant contexts where most attend school. This explanatory sequential mixed-methods study first quantitatively examines adults' use of Spanish…

Little research has highlighted how evidence-based practices (e.g., functional communication training [FCT]) might be adapted for bilingual learners with disabilities. In the current study, we served 2 children with autism spectrum disorder (ASD) and challenging behavior whose parents primarily spoke Spanish at home, and whose teachers primarily…

This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

This study investigates the longitudinal development of language attitudes towards Catalan and Spanish over a five-year period in the transition from primary to secondary education of a sample of students (N = 1,143) in Catalonia and Aragon. Two research questions were investigated: (1) How do language attitudes develop over time? and (2) How do…

This article examines caregivers' everyday language choices and interactions with children in an urban Zapotec community in Mexico, where Diidxazá is being displaced by Spanish in everyday use. It argues that caregivers' language choices and interactions get entangled in complex ways with the socio-cultural organization of everyday life and with…

While language dominance has been crucial in the study of bilingualism, recent research has called for more detailed measures to systematically account for the observation that bilinguals use different languages in different domains, a phenomenon formalized in the Complementary Principle. Few studies have systematically measured these…

In the United States nearly one third of children under five live in homes where a non-English language is spoken. However, many of these language-minority (LM) children shift towards English monolingualism after beginning school in early childhood. While language input and usage are central to acquisition and maintenance in each language, less is…

Most bilingual children often display greater proficiency and preference for one of their two languages. Researchers refer to this asymmetry as language dominance. However, despite being possible to determine the overall language dominance in bilinguals, there may be substantial flexibility in their language use. In particular, the relative ease…
