Speakers monitor their own speech for errors. To do so, they may rely on perception of their own speech (external monitoring) but also on an internal speech representation (internal monitoring). While there are detailed accounts of monitoring in first language (L1) processing, it is not clear if and how monitoring is different in a second language…

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…

The "Common European Framework of Reference" (CEFR) is the most widespread reference tool for linking language tests, curricula, and national educational standards to levels of foreign language proficiency in Europe. In spite of this, little is known about how the CEFR levels (A1-C2) relate to empirical learner language(s). This article…

This article focuses on the use of collocations in language learning research (LLR). Collocations, as units of formulaic language, are becoming prominent in our understanding of language learning and use; however, while the number of corpus-based LLR studies of collocations is growing, there is still a need for a deeper understanding of factors…

This study investigated how adult second language (L2) speakers of French with near-native proficiency realize verbal negation, a well-known sociolinguistic variable in contemporary spoken French. Data included 10 spontaneous informal conversations between near-native speakers of French and native speakers (NSs) closely acquainted with them.…

Second language (L2) learning outcomes may depend on the structure of the input and learners' cognitive abilities. This study tested whether less predictable input might facilitate learning and generalization of L2 morphology while evaluating contributions of statistical learning ability, nonverbal intelligence, phonological short-term memory, and…

Answering calls to map college-level proficiency development (Modern Language Association, 2007) and longitudinally chart language learning (Barkaoui, 2014; Ortega & Byrnes, 2008), we mapped the oral proficiency growth of 1,922 lower-division college students of Chinese, French, Russian, and Spanish (in the second, third, or fourth semester of…

This study examined the acquisition of a linguistic property that is underrepresented in the input available to second language (L2) learners, namely, interpretation of French strong pronouns as [-animate]. To understand how pronouns are used and interpreted and how this topic is treated in pedagogical grammars, three types of analyses were…

Explicit attention to research design issues is essential in experimental second language (L2) research. Too often, however, such careful attention is not paid. This article examines some of the issues surrounding experimental L2 research and its relationships to causal inferences. It discusses the place of research questions and hypotheses,…

This longitudinal randomized trial study investigated the effects of phonological specificity training on second language (L2) vocabulary learning. Eighty-six Dutch secondary-school students participated in one of two experimental conditions or in an animacy judgment (active control) condition. Participants in the phonological specificity training…

This study investigated the relative effectiveness of two instructional interventions (implicit and explicit feedback) as a function of implicit sequence-learning ability. Second language (L2) attainment was measured by means of a self-paced reading task, which shows online sensitivity to language errors. Implicit sequence-learning ability was…

Language mixing in a given class is often avoided in bilingual education because of the generally held belief that "one subject" should be taught in only "one language" and "one person" should stick to "one language" in order to minimize confusion. Here, we compared the effects of mixing two languages and…

Despite contrary research findings, many laypeople still claim that starting second language (L2) instruction early yields linguistic advantages. This assertion is again undermined by a 5-year longitudinal study conducted in Switzerland testing the English language skills of 636 secondary-school students who had all learned Standard German and…

This study compares the performance of native speakers and adult second language (L2) learners on tasks tapping proficiency in grammar, vocabulary, and collocations. In addition, data were collected on several predictors of individual differences in linguistic attainment, including some related to language experience (print exposure, education,…

We examined case-marking variation in heritage Polish, Russian, and Ukrainian. Comparing heritage to homeland Polish and Ukrainian speakers, we found only a few types and a few tokens of systematic distinction between heritage and homeland varieties. A total of 6,291 instances of nouns and pronouns were extracted from transcribed conversations…
