Interactions with classroom friends may be an important contributor to first and second language development, but to date this hypothesis has not been tested. Using a longitudinal design, the current study investigated the relationship between classroom friendships and oral language development in children. In 8 classrooms, we assessed the…

Usage-based approaches to additional-language acquisition have identified numerous determinants of language learning, two of which were the focus of our study: frequency and cue contingency. Specifically, we examined how an immersion experience may impact sensitivity to these two determinants as reflected in the production of 4,808 pairs of nouns…

This study examined how Korean EFL learners in different proficiency levels attest contrasts of L2 phonology. To this end, twenty Korean EFL learners in high and low levels of English proficiency produced words with word-final contrasts of /[esh]/ vs. /[esh]i/, /t[esh]/ vs. /t[esh]i/, and /d[ezh]/ vs. /d[ezh]i/. Acoustic analyses of lexical vs.…

This study employed a mixed-methods approach to explore the attitudes of second language (L2) learners and L2 teachers toward the use of learners' first language (L1) in L2 classrooms. Interview data were collected from Japanese college students (n = 91) and their English teachers (n = 9) to identify salient themes related to the reasons for…

Vocabulary assessment is an important part of measuring language proficiency in both monolingual and bilingual children. The LITMUS Cross-Linguistic Lexical Tasks (CLT) provides a framework for assessing the vocabulary of monolingual and bilingual children using a standardized procedure and comparable stimuli across languages. All language…

This longitudinal study explores cross-language transfer among children attending multilingual public schools in Luxembourg, where Luxembourgish is the instruction language in preschool and German the language of instruction in elementary school. Following 132 children from preschool (age 5) to grade 2 (age 7), annual assessments were conducted to…

This study investigates the cross-linguistic transfer of literacy skills in Spanish-English, Chinese-English bilingual, and English monolingual children (N = 283, 5-10 years). Research question 1 examines English literacy and asks how phonological and morpho-semantic skills contribute to word reading as a function of children's language…

This paper reports on an investigation of differential item functioning (DIF) in the Iranian Undergraduate University Entrance Special English Exam (IUUESEE) across four native language groups including the Azeri, the Persian, the Kurdish, and the Luri test takers via Rasch analysis. A total sample of 14,172 participants was selected for the…

26% of the students in Swedish compulsory school have an immigrant background. To support the simultaneous development of their language proficiency as well as their academic skills and knowledge, several measures may be implemented by schools. This study focuses on one of those measures, namely multilingual study guidance, and illustrates the…

With a focus on an under-studied group of immigrants in the UK, this paper examines Iranian families' language ideologies and practices at home in relation to Persian acquisition and maintenance for their children. Working within a family language policy (FLP) framework, we draw on sociolinguistic data from semi-structured interviews with eighteen…

A central question in multilingualism research is how multiple languages interact. Most studies have focused on first (L1) and second language (L2) effects on a third language (L3), but a small number of studies dedicated to the opposite transfer direction have suggested stronger L3 influence on L2 than on L1 in postpuberty learners. In our study,…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

The Imperfect/Preterite aspectual contrast is one of the most studied topics in Spanish as a second language research. However, there are few works focused on describing the acquisition of modal uses of the Imperfect by L2 speakers. This paper investigates the L1 Russian L2 Spanish speakers' mastery of politeness, evidential and nonfactual modal…

Previous research has shown that bilinguals respond differently to moral dilemmas posed in each of their languages, tending to make deontologically-based decisions (based on right or wrong) in their first language and utilitarian decisions (bringing about the most good) in their second language. In the present study, we tested several predictors…

This study proposed an innovative automated approach to differentiation of the vocabulary proficiency of Chinese speakers. A robust K-means algorithm was designed to compare the oral proficiency between L1 and L2 Chinese speakers regarding lexical richness and how relatively effective the various lexical measures were in performing the…
