The Portuguese present perfect (P-PP) is an understudied topic in the field of generative language acquisition. In the past decade, Third Language Acquisition (L3A) has enjoyed special attention in studying how multilingualism works. Researchers have concentrated on the examination of the source of transfer at the initial stages. However, there is…

In bilingual children, more so than in monolingual children, comprehension abilities exceed production abilities. While this receptive-expressive gap in bilinguals has been well documented, little is known about its development. The present study tracked growth in the Spanish and English receptive and expressive vocabularies of 52 bilingual…

The purpose of the current study was to examine the influence of L1 (i.e. Spanish) receptive vocabulary on both expressive and receptive knowledge of target vocabulary words taught through L2 (i.e. English) instruction and intervention. Participants were Bilingual US kindergarten students determined to be at-risk based on English receptive…

Purpose: The purpose of this study was to identify and describe latent dual language profiles in a large sample of school-age Spanish-English bilingual children designated as English learners (ELs) by their school district. Method: Data for this study include 847 Spanish-speaking ELs from kindergarten to third grade. Spanish and English narrative…

Purpose: This study investigated the longitudinal, cross-linguistic developmental relationships of phonological awareness (PA), letter identification (letter ID), and morphological awareness (MA) in 71 heritage Spanish-English dual language learners (DLLs) in kindergarten and second grade. Method: Multiple linear regression was used to test if…

Purpose: This study examined the effect of phonological overlap on English and Spanish expressive vocabulary accuracy as measured by the bilingual Expressive One-Word Picture Vocabulary Test--Fourth Edition (EOWPVT-IV). We hypothesized that if languages interact during an expressive vocabulary task, then higher phonological overlap will predict…

A vast amount of Latina/o/x students enroll in US public schools with the potential to become bilingual in English and Spanish. However, this potential is often dismissed, ignored, and their Spanish is perceived as a problem to be overcome. Despite this, some Latina/o/x bilingual students decide to become Spanish as a Heritage Language (SHL)…

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…

We conducted a stimulus preference assessment to identify preference for praise delivered in English versus Spanish for bilingual students. Next, a concurrent-operant reinforcer assessment was used to evaluate the reinforcer efficacy of praise in each language. Participants showed limited to no preference for one language over another. One…

The purpose of this study was to assess the use of an adapted picture description task described by Eisenberg and Guo to explore the morphosyntactic error patterns of English-Spanish preschool simultaneous bilingual learners. Language samples were collected from 28 bilingual preschool children aged 3 to 5 years. Language samples were elicited in…

The U.S. population has become more racially and ethnically diverse over time. The Latinx population growth makes Spanish the most common language encountered in non-native English-speaking populations such as Texas. The research objective of this study was to examine if implementing a One-Way Dual Language Education (DLE) Program could result in…

We examined the relations of language skills (vocabulary, listening comprehension, and oral retell), transcription skills (spelling and handwriting fluency), and domain-general cognitions/executive functions (working memory and attentional control) to writing quality for English-Spanish emergent bilingual children in Grade 1. Data were from a…

To date, most classroom-based research into the learning of a third language (L3) in the US has examined patterns of acquisition among various groups of bilinguals. Situated mainly within the context of "Portuguese for Spanish Speakers" (PSS), studies typically group learners based on the sequence / age of onset of their main background…

This dissertation was an investigation of how students in two-way bilingual immersion (TWBI) programs construct their bilingual identities inside and outside the school setting, highlighting the unique and multifaceted nature of their language development and cultural identity formation. TWBI programs aim to cultivate bilingualism and biliteracy,…
