Chinese immersion programs have been increasingly popular in US schools. However, we have insufficient data on young English-speaking children's acquisition of Chinese as a second language in these programs, and specifically on social contextual variables systematically promoting or hindering Chinese language use. Taking a variationist…

To respond to recent calls for examining oral fluency from a broader social and communicative perspective, the current study aimed at investigating the effects of task communicative function on second language (L2) and first language (L1) speakers' fluency. Designing tasks that represent three different communicative functions (congratulations,…

Although English and German are both Germanic languages, due to various historical changes, many of their cognates are no longer easily recognizable. This study examined whether knowledge of language history can be beneficial to learners when learning English-German cognates. Thirty-five English-speaking second language (L2) learners of…

The simple view of reading (SVR) model proposes that reading comprehension is the product of cognitive domain skills, word decoding, and oral language (linguistic) comprehension, and that decoding and language comprehension make separate, independent contributions to reading comprehension. The SVR has been supported in both first (L1) and second…

French second language education, including the option of one-way French immersion, is mandated for majority-language Anglophone children in New Brunswick, Canada's only officially bilingual province. Language ideological debates in the province surrounding official English--French bilingualism led us to investigate adolescent majority-language…

This data-driven study framed in the interactionist approach investigates the influence of social graph topology and peer interaction dynamics among foreign exchange students enrolled in an intensive German language course on second language acquisition (SLA) outcomes. Applying the algorithms and metrics of computational social network analysis…

This study investigated the effects of temporal distribution of practice on the learning and retention of Mandarin tonal word production. Eighty native English-speaking adults with no prior knowledge of a tonal language participated in this study. They were randomly assigned to four experimental conditions varying in intersession interval (ISI)…

This study examines first language (L1) English transfer in the acquisition of plural noun semantics in second language (L2) Arabic. Drawing on previous research on the L2 acquisition of plural noun interpretation, the study presents and discusses new production data of specific and generic definite plurals by English-speaking learners of Arabic…

This study examines the putative benefits of explicit phonetic instruction, high variability phonetic training, and their effects on adult nonnative speakers' Mandarin tone productions. Monolingual first language (L1) English speakers (n = 80), intermediate second language (L2) Mandarin learners (n = 40), and L1 Mandarin speakers (n = 40) took…

The present study investigates to what extent first-language (L1) and second-language (L2) speakers use lexical futures, whether such forms provide evidence of development, and whether these forms are constrained differently from the present indicative (PI) according to linguistic predictors. It uses a combined approach through its…

We examined the role of modality in learning second language (L2) grammar and forming implicit (unconscious) and explicit (conscious) knowledge. To this end, we isolated the effects of the physical medium of input (i.e., aural or visual) from those of the presentation method (i.e., word-by-word or simultaneous). We also explored the role of test…

The present study investigated a group of cognitive individual differences considered advantageous in second language learning and their role in language learning under implicit and explicit feedback conditions using both language awareness and language development measures. The study further investigated whether different types of awareness are…

The aim of this article is to show that the use of Spanish grammatical aspect is biased by inherent aspect depending on the learner's first language (L1). It considers both the Lexical Aspect Hypothesis (LAH; Andersen, 1986, and his followers) and the L1 Transfer Hypothesis (Izquierdo & Collins, 2008; McManus, 2015), and it compares the use of…

Within limited-input language classrooms, understanding the effect of distribution of practice (spacing between practice) on learning is critical, yet evidence is conflicting and of limited relevance for young learners. For second language (L2) grammar learning, some studies reveal advantages for spacing of 7 days or more, but others for shorter…

We take a multidimensional perspective on the development of second language (L2) speaking ability and examine how changes in the underlying cognitive variables of linguistic knowledge and processing speed interact with complexity, fluency, and accuracy over the course of a 3-month Spanish study abroad session. Study abroad provides a unique…
