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?…

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…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results.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

Purpose: This longitudinal study assessed continuity and stability of productive language (vocabulary and grammar) and discourse features (turn-taking; asking and responding to questions) during mother-child play. Method: Parent-child language use in 119 Spanish-speaking, Mexican immigrant mothers and their children at two ages (M = 2.5 and 3.6…

This study examined linguistic development among both intermediate and advanced college-level second language (L2) learners during short-term study abroad summer programs in Spain. Participants completed a measure of overall proficiency, as well as assessments of receptive grammatical (morphosyntactic) and lexical (semantic) abilities at the…

Hundreds of millions of language learners around the globe study a second language with popular apps such as Duolingo, Rosetta Stone, Busuu, and Babbel. This study examined the effectiveness of one app, Babbel, for developing both receptive linguistic knowledge of vocabulary and grammar, as well as oral communicative ability in Spanish as a second…

This article examines factors that promote active multilingualism. For this purpose, the "Peabody Picture Vocabulary Test" was used with 48 children. Their results were linked to a parental questionnaire designed to evaluate the children's linguistic input in their immediate environment. The study shows that, besides a minimum amount of…

The purpose of this cluster randomized group study was to investigate the effect of multitiered, dual language instruction on children's oral language skills, including vocabulary, narrative retell, receptive and expressive language, and listening comprehension. Participants were 3-5 year old children (n = 81) who were learning English and whose…

Purpose: This study investigated within-language and between-language associations between phonological memory, vocabulary, and grammar in French-English (n = 43) and Spanish-English (n = 25) bilingual children at 30, 36, and 48 months. It was predicted that phonological memory would display both within-language and between-language relations to…

In this study, monolingual (English) and bilingual (English/Spanish, English/Urdu) five- and six-year-old children completed a grammaticality judgment test in order to assess their awareness of the grammaticality of two types of syntactic constructions in English: word order and gender representation. All children were better at detecting…

This study contributes to what is known about the nature of unbalanced bilingualism that emerges in language contact situations by examining the morphological knowledge of Spanish receptive heritage bilinguals (RHBs). RHBs were exposed to Spanish in their homes and communities but received formal schooling in English. These bilinguals have been…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

This study compared receptive English grammar skills of two groups of 7- and 9-year-old Danish children at the beginning of second language (L2) instruction in English, and two groups of Spanish/Catalan children of the same age after several years of instruction. The study examined the influence of two language-related factors (receptive…

This study investigates the role of biological age and L2 exposure on the achievement of two groups of Catalan-Spanish intermediate learners of English in secondary school (Group A, Formal Instruction (FI), N = 50; Group B, FI + CLIL, N = 50) regarding receptive and productive L2 skills as well as grammatical knowledge. Learners were matched for…

Purpose: This study examined the latent dimensionality of Spanish in young Spanish-English dual-language learners (DLLs). Method: Two hundred eighty-six children participated. In their prekindergarten year, children completed norm-referenced and experimental language measures in Spanish requiring different levels of cognitive processing in both…
