This longitudinal study (data collected from 2019 to 2023) examines the relation between Spanish-English bilingual Latino toddlers' (n=46; F=22; M=24) early gesture production (Mage=18.67 months; SD[subscript age]=1.02) and later language skills (M[subscript age]=36.87 months; SD[subscript age]=0.81). Video recordings at child-age 18-months…

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…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

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…

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…

Seven cohorts of students (N = 258) who completed a K-5 Spanish Immersion (SI) program in a suburban California school district were followed longitudinally through middle and high school to understand their academic, language, and social emotional outcomes. Academic and language outcomes included Spanish classes and grades, standardized Math and…

This longitudinal study tracked ten L1 English-speaking learners' acquisition of Spanish voiceless stops /ptk/ by measuring their voice onset time (VOT) over an academic year in two distinct contexts of learning. Living in a Spanish-speaking dorm, participants in the experimental group experienced a "domestic partial-immersion," in which…

This study explored the initial stages of adult second language (L2) learning with a special focus on the acquisition of the target language sound system. The aim was to analyze the longitudinal development of Spanish stop voicing contrasts in an immersion learning context. Native English-speaking late learners of Spanish provided production data…

This study explores the experiences of second-generation Latine adolescents by examining the impact of bilingualism on self-esteem and depressive symptoms. Drawing on Suarez-Orozco and colleagues' (2018) model, this study shows the multifaceted acculturation process, emphasizing linguistic acculturation as crucial for navigating two cultures. The…

Purpose: This study aimed to examine changes in English and Spanish morphosyntactic standardized scores over time in bilingual children. Method: One hundred bilingual children participated in this longitudinal study. The average age of the children at the beginning of the study was 5;11 (years; months). A subset of the participants was identified…

Most studies on the perception-production link have assumed a synchronous relationship according to which gains in perception transfer to production rapidly and efficiently. However, time-lagged and asymptotic relationships are also possible, where perception would guide production at a later stage or production would improve only once perception…

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…

Purpose: This longitudinal study investigated the trajectory of Spanish article accuracy in Spanish-English dual language learners (DLLs) from preschool to first grade, addressing the need for longitudinal data on the variability of Spanish grammatical skills in DLLs in English immersion classrooms. Method: Language sample analysis was conducted…
