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?…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results.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…

Autism Spectrum Disorder (ASD) and epilepsy represent a comorbidity that negatively influences the proper development of linguistic competencies, particularly in receptive language, in the pediatric population. This group displays impairments in the auditory comprehension of both simple and complex grammatical structures, significantly limiting…

Bilingual children demonstrate varying levels of proficiency in each of the two languages to which they are exposed. Even though it is widely acknowledged that bilingual children are not a homogenous group, existing studies on dual-language profiles in bilingual children have focused on expressive language profiles. In this study, we used the…

This study examines the role of receptive vocabulary knowledge on outcomes of the TOEFL reading comprehension task. Participants included 18 native speakers of Spanish learning English as a foreign language and 17 native speakers of English ranging in age from 19-25 years. Lexical stimuli were presented auditorily and were divided into…

Recent literature in the field of L2 vocabulary assessment has advocated for the development of written receptive vocabulary tests such as Vocabulary Levels Tests (VLTs) that use: (a) meaning-recall item formats, (b) a minimum of 40 item counts per 1,000-frequency band to improve level estimates, and (c) lemmas (not word-families) as the lexical…

In this single-case study with a quasi-experimental design, we set out to examine the role of two input-based features of the language learning app Duolingo on learners' development of implicit and explicit second language (L2) knowledge. We investigated the effect of Duolingo's Stories feature and Podcast feature on two Spanish-L2 learners'…

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 current work investigates whether language dominance predicts transfer of skills across cognitive-linguistic levels from the native language (Spanish) to the second language (English) in bilingual preschoolers. Sensitivity to cognates ("elephant/elefante" in English/Spanish) and metalinguistic awareness (MLA) have both been shown to…

This study aims to measure the longitudinal impact of a 60-hour adjunct instruction course, involving L2 content-based teaching with a systematic focus on form, on students' grammatical and lexical knowledge and on their receptive skills (i.e. reading and listening) in a foreign language higher education context. The participants were 52…

Purpose: Despite the increasing population of dual language learners (DLLs) in the United States, vocabulary measures for young DLLs have largely relied on instruments developed for monolinguals. The multistudy project reports on the psychometric properties of the English--Spanish Vocabulary Inventory (ESVI), which was designed to capture unique…

Purpose: This study investigated the effect of delivery method (face-to-face or telepractice), time, home language, and language ability on bilingual children's receptive vocabulary scores in Spanish and English. Method: Participants included bilingual children with (n = 32) and without (n = 57) developmental language disorders (DLD) that were…

Research Findings: We examined the amount of preschool lead/assistant teachers' English/Spanish language use and relations between quality of teacher-child interactions, and Dual Language Learners' (DLLs) English/Spanish bilingual vocabulary in 31 English-medium Head Start classrooms. Measures in this study included (a) children's conceptual…

It is well-documented that there is a strong relationship between vocabulary and reading comprehension in school-age children. Limited vocabulary knowledge can impact a student's reading achievement, as may be the case for school-age English Learners (ELs). This study aims to analyze the role of vocabulary in predicting reading comprehension…

To date, several studies have investigated the potential benefits of using Quizlet and podcasts for vocabulary development. However, they have mainly focused on the use of available material, and its effects on receptive vocabulary acquisition and students' motivation. In contrast, relatively little has been done to study the effects of…
