Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

This systematic review aims to explore how task complexity and task sequencing affect the complexity, accuracy, and fluency (CAF) of second language performance. Through an analysis of studies conducted between 2012 and 2021, this review investigates the characteristics of the studies, operationalisation of task complexity, measurements of CAF,…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

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…

The amount of language input bilingual children receive influences their language acquisition. This three-year quasi-longitudinal study determined the extent home language input influences measures of expressive and receptive English vocabulary among Spanish-English school-age bilingual children. The study also determined whether a relationship…

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…

The Null Subject Parameter (NSP) has long been considered pertinent to Second Language Acquisition (SLA) studies, especially when the native language (NL) and target language (TL) have different NSP settings. The study aimed to investigate whether seventy English L2 learners in Puerto Rico who were native Spanish speakers transferred their L1…

This study examined how two Translanguaging (TL) modes impact multilingual students' English skills. It also investigates the perceived benefits and disadvantages of the translanguaging practices used by both students and teacher. The research sample comprised 96 multilingual students divided into three groups: a control group and two experimental…

Research on Spanish heritage language (SHL) education has grown exponentially in the last two decades. The most recent nationwide study on SHL programs in US postsecondary institutions was conducted a decade ago. To continue this line of research, the primary aim of this study is to provide an update about the current state of SHL course offerings…

The current diagnostic criteria for the autism spectrum disorder (ASD) include the possibility to specify concomitant language difficulties. Purpose: Our main aim was to explore whether children with ASD-Level 1 (ASD-L1) present difficulties in the acquisition of structural language, as little work has been done in this regard so far. As a…

This article examines cases where two study abroad students--Rita and Jack--problematized the normative use of specific dialectal variants by local native speakers at the end of their Spanish immersion program in Peru. Specifically, it explores what these cases reveal about second language learners' sociolinguistic competence in a study abroad…

In the aftermath of the COVID-19 pandemic, we continue to take stock of student learning. Although the "crisis-context" (Gacs et al., 2020) move to fully online instruction may be over, a complete understanding of how student outcomes have been impacted remains. The present study focuses on how students' Spanish language proficiency, as…

Bilingual children, the majority of whom are Spanish-English learners, now constitute over a third of the preschool population in the United States (Migration Policy Institute, 2021). Bilingual children and their families face multiple barriers to high-quality early childhood education, which are largely due to the underutilization of culturally…

This study counters the popular assumption that Spanish Heritage Language Learners (SHLLs) on study abroad (SA) in a place of cultural origin can easily adapt and find acceptance due to the linguistic and cultural resources they bring with them. Our study builds on previous work to illustrate a more nuanced and complex story of desires for…

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…
