Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed…

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…

The current longitudinal, mixed-methods dissertation explored how various Family Language Policy (FLP) factors (including parent and child language ideologies, practices, and management) influence "Español"-English (hereafter, "Españ"Eng) bilingual students' home language maintenance/loss and their bilingual development.…

Despite the widespread use and effectiveness of the Modern Language Aptitude Test (MLAT) composite score in predicting individual differences in L2 achievement and proficiency, there has been little examination of MLAT subtests, although they have potential for illuminating components of L2 aptitude and the mechanism of prediction. Here we use…

orInverse relations, or "trade-off effects," are a common outcome of interlanguage development: a learner may increase performance in one linguistic domain while simultaneously decreasing performance in another. In this study, we investigate the relationships between one aspect of fluency (pause usage) and two aspects of syntactic…

The purpose of this qualitative research study is to portray the complex language practices of multilingual children when learning mathematics. To do so, I draw on data collected as part of a three-year research study that was designed to understand the relationship between young children's language use and mathematics learning, focusing on…

Many second language (L2) learners participate in study abroad (SA) experiences believing their choice will be synonymous with increased interaction in the L2, from which enhanced linguistic gains will ensue. Nonetheless, one open question is whether SA participants actually engage in sustained L2 interaction while they are abroad. This paper…

This study qualitatively explores how studying abroad in an English as a lingua franca context promotes student-sojourners' intercultural awareness (ICA) taking a longitudinal perspective. A group of Catalan/Spanish bilinguals and Turkish-L1 speakers were interviewed regarding their past ERASMUS experiences in terms of ICA following a stimulated…

This study describes academic literacy development during mid-adolescence, when learners need to adjust to the demands of academic discourse as a gateway to linguistic adulthood. Unlike most research to date, which is cross-sectional and detached from disciplinary content, this study provides a two-year longitudinal description of academic…

Linguistic research on bilinguals has sometimes focused on either first vs. second acquired language or dominant vs. non-dominant language despite situations in which the dominant and first language are no longer the same. Many bilinguals in the U.S. and other countries experience a change in language dominance from a home language to a majority…

Spanish-speaking students constitute the largest subgroup of emergent bilingual (EB) students in the United States. Using longitudinal data on a nationally representative sample of Spanish-English EBs, we explore profiles of English reading trajectories and how early individual differences (i.e., early Spanish reading and English oral proficiency)…

In this preregistered, longitudinal study of early code-switching, 34 US-born, Spanish-English bilingual children were recorded with a bilingual family member at 2;6 and 3;6, in Spanish-designated and English-designated interactions. Children's Spanish and English expressive vocabulary and their exposure to code-switching were measured through…

Recent longitudinal approaches to second language (L2) pronunciation development have prioritized developmental trajectories, highlighting individual variation in phonetic learning over time. Aligning with this research paradigm, the present study examined voice onset time (VOT) production in Spanish/b/and/p/ over two semesters of elementary…

Adult first language (L1) English speakers who are advanced second language (L2) learners of Spanish demonstrate near-ceiling levels of accuracy for some features of Spanish, such as [Person] and [Number] for verbs (McCarthy, 2012; Rodgers, 2011). While for other features, such as [Aspect] for copulas (i.e. ser and estar), and [Person] and…

This study investigated family and coach responses to a two-year community-based research program, Strong Beginnings for Babies (SBB), designed to support families in fostering infant language development. The study focused on families of infants from low-income backgrounds, as these children may be at risk for delayed language development. The…
