Second language acquisition researchers often face particular challenges when attempting to generalize study findings to the wider learner population. For example, language learners constitute a heterogeneous group, and it is not always clear how a study's findings may generalize to other individuals who may differ in terms of language background…

This study examined the progress in lexical and grammatical knowledge among 252 learners of French in England across the last two years of primary education and into the first year of secondary school in relation to teaching and teacher factors. It compared linguistic outcomes from two different approaches, one which emphasized oracy and the other…

Foreign language education has now been implemented at the elementary school level across Europe, and early foreign language education has gained traction following language policies set by the European Commission. The long-term effects of an early start, however, have not received ample scientific scrutiny. The present study assessed early…

Although fluency constitutes an essential component of second language (L2) proficiency, there are mixed results and gaps in the literature on how L2 speakers' fluency differs from fluent speech production in a first language (L1). The research reported in this article investigated utterance fluency and cognitive fluency of L1 English…

This nonexperimental study explored the predictive strength of English proficiency levels on academic achievement of middle school students in a sample of 17,470 native English-speaking (NES) students, 558 English language learners (current ELLs), and 500 redesignated fluent English proficient students (former ELLs). Results of multilevel analyses…

This study employed an artificial language learning paradigm together with a combined behavioral/event-related potential (ERP) approach to examine the neurocognition of the processing of gender agreement, an aspect of inflectional morphology that is problematic in adult second language (L2) learning. Subjects learned to speak and comprehend an…

Learning context has increasingly been postulated to exert an influence on the dynamics of individual differences in language learning. In a longitudinal design that tested the proficiency gains of 1,682 learners over a 2-year foreign language program, a multilevel modeling approach was deployed in this study to account for variation in second…

There is little agreement on the mechanisms involved in second language (L2) processing of regular and irregular inflectional morphology and on the exact role of age, amount, and type of exposure to L2 resulting in differences in L2 input and use. The article contributes to the ongoing debates by reporting the results of two experiments on Russian…

This study considered the effects of trait emotional intelligence (trait EI; Petrides & Mavroveli, 2007) and sociobiographical variables (age, gender, education level, number of languages known, age of onset of acquisition, context of acquisition, frequency of use, socialization, network of interlocutors, self-perceived proficiency) on…

Investigates factors influencing Japanese university students' expository writing in English. Quantitative analysis revealed that students' second-language (L2) proficiency, first-language writing ability, and metaknowledge were significant in explaining L2 writing ability variance. An explanatory model for writing ability in English as a Foreign…

Analyzes the mental organizations of two sets of fuzzy lexical items by 70 native speakers (NSs) of English and 185 learners of English as a Second Language (ESL). Findings suggest that a discernible approximative pattern exists in the acquisition of ESL semantics, with the differentiation of certain words acquired before the differentiation of…

Studies learners' second-language (L2) oral proficiency, incorporating an interview, a narration, and a read-aloud. Results show that the nature of the L2 oral construct is not constant. The article concludes that proficiency researchers should use dimensions empirically derived according to the specific elicitation task and audience. (53…
