This study longitudinally examined the effects of cognitive and sociopsychological individual differences (aptitude, motivation, personality) and the quantity and quality of second language (L2) experience on L2 speech gains in naturalistic settings. We elicited L2 spontaneous speech from 50 Chinese learners of English at the beginning and the end…

In the present study, we sought to advance the field of learner corpus research by tracking the development of phrasal vocabulary in essays produced at two different points in time. To this aim, we employed a large pool of second language (L2) learners (N = 175) from three proficiency levels--beginner, elementary, and intermediate--and focused on…

The current study responds to the call for increased dialogue among different areas of additional language research. Specifically, we bring together learner corpus research and variationist approaches to second language acquisition to advance learner corpus research in two ways: (a) by modeling interlanguage development and variability and (b) by…

This study presents a cross-sectional and longitudinal analysis of how 108 high school students in English as a foreign language (EFL) classrooms enhanced the comprehensibility of their second language (L2) speech according to different motivation, emotion, and experience profiles. Students' learning patterns were primarily associated with their…

Usage-based approaches explore how we learn language from our experience of language. Related research thus involves the analysis of the usage from which learners learn and of learner usage as it develops. This program involves considerable data recording, transcription, and analysis, using a variety of corpus and computational techniques, many of…

In bilinguals and second language learners, the native (L1) and nonnative (L2) languages coexist and interact. The L1 influences L2 production via forward transfer, as is seen with foreign accents. However, language transfer is bidirectional: even brief experience with an L2 can affect L1 production, via backward transfer. Here, we review the…

Drawing on usage-based linguistics and its exemplar-based path of language learning, from recurring multiword expressions to increasingly abstract, schematized constructions, this article examines evidence for the exemplar-based developmental sequences for yes/no interrogatives and WH interrogatives in English as a second language (L2). The…

Humor and language play have been recognized as important aspects of second language (L2) development. Qualitative studies that have documented the forms and functions of language play for adult and child L2 users have taken place largely in classroom settings. In order to gain a fuller understanding of such creative manipulations by L2 users, it…

This article explores the usage- and exemplar-based roots of second language (L2) negation construction learning. Based on two longitudinal case studies involving two adult L2 English learners and a corpus of 63 three-hour sessions of recorded classroom interactions, the study shows that L2 learning follows the predictions of usage-based models of…

Researching the longitudinal development of second language (L2) learners is essential to understanding influences on their success. This 7-year study of oral skills in adult immigrant learners of English as a second language evaluated comprehensibility, fluency, and accentedness in first-language (L1) Mandarin and Slavic language speakers. The…

This article presents an analysis of interactions in the usage, structure, cognition, coadaptation of conversational partners, and emergence of linguistic constructions. It focuses on second language development of English verb-argument constructions (VACs: VL, verb locative; VOL, verb object locative; VOO, ditransitive) with particular reference…

This study examined how 16 adult learners of English as a Second Language (ESL) in an intensive ESL program used tense contrast and time adverbials to produce reverse-order reports. The study found that the students marked reverse-order reports as deviations from chronological order by their use of tense contrast and time adverbials. (26…

Reports on an eight month study examining the development of turn-allocation devices in children acquiring English as a second language. The role of prior language experience in second language learning is explored. (Author/AM)

Examined whether there is an earlier developmental stage than 2 years of age when bilingual children do not use their languages in pragmatically differentiated ways. Analyses of recordings of four French-English bilingual children in Canada during free play sessions with their mothers and fathers suggest a stage very early in development when…
