The role of attention has been central to theoretical and empirical inquiries in second language (L2) acquisition. The current eye-tracking study examined how external and internal attentional manipulations (Chun, Golomb, &Turk-Browne, 2011) promote L2 grammatical development. Participants (n = 55) were exposed to Spanish direct-object…

Language-analytic ability, or the ability to treat language as an object of analysis and arrive at linguistic generalizations, is at the core of the constructs of language learning aptitude and metalinguistic awareness, which are implicated in our ability to learn explicitly. In the context of child second language (L2) learning, it has been…

This paper presents an experimental study of the rarely explored question of how input through instruction interacts with L2 acquisition at the level of modular linguistic knowledge. The investigation focuses on L2 knowledge of the English polarity item "any," whose properties are only partially covered by typical language-teaching…

To what extent do second language (L2) learners benefit from instruction that includes corrective feedback (CF) on L2 speech perception? This article addresses this question by reporting the results of a classroom-based experimental study conducted with 32 young adult Korean learners of English. An instruction-only group and an instruction + CF…

This study focused on an instructional component often neglected when teaching the pronunciation of English as either a second, foreign, or international language--namely, the suprasegmental feature of lexical stress. Extending previous research on collaborative priming tasks and task repetition, the study investigated the impact of task and…

Second language learning outcomes are highly variable, due to a variety of factors, including individual differences, exposure conditions, and linguistic complexity. However, exactly how these factors interact to influence language learning is unknown. This article examines the relationship between these three variables in language learners.…

Although previous research has demonstrated the efficacy of recasts on second language (L2) morphology and lexis (e.g., Li, 2010; Mackey & Goo, 2007), few studies have examined their effect on learners' phonological development (although see Saito, 2015; Saito & Lyster, 2012). The current study investigates the impact of recasts on the…

In the previous 20 years, more than 60 studies have been carried out within the input and interaction approach to SLA (Long, 2007; Mackey 2012), many of which have found positive associations between different types of recasts and the learning of a range of linguistic forms for a number of different second languages (L2s), in different learning…

This study compares the effects of processing instruction (PI), structured input (SI), and form-related explicit information (FREI) on a primary target form (i.e., third-person Spanish accusative clitics) and on a secondary form (i.e., third-person Spanish dative clitics). Participants included 151 adult learners enrolled in a beginning-level…

The present study examines whether and to what degree providing explicit phonetic information (EI) at the beginning of form-focused instruction (FFI) on second language pronunciation can enhance the generalizability and magnitude of FFI effectiveness by increasing learners' ability to notice a new phone. Participants were 49 Japanese learners of…

The literature on corrective feedback (CF) that second language writers receive in response to their grammatical and lexical errors is plagued by controversies and conflicting findings about the merits of feedback. Although more recent studies suggest that CF is valuable (e.g., Bitchener, 2008; Sheen, 2007), it is still not clear whether direct or…

The role of explicit information (EI) as an independent variable in instructed SLA is largely underresearched. Using the framework of processing instruction, however, a series of offline studies has found no effect for EI (e.g., Benati, 2004; Sanz & Morgan-Short, 2004; VanPatten & Oikkenon, 1996). Fernandez (2008) presented two online experiments…

Discusses the connection between second language acquisition (SLA) research and second and foreign language (S/FL) teaching from the viewpoint that such a relationship is desirable and that it is advantageous to see it as one mediated by various factors. Argues that the relationship is presently often weaker than it should be, particularly owing…

Describes a study which investigated and described the linguistic input and conversational interaction found in English as a second language classrooms when small groups of students work together. The results are compared with classroom activities in which the students participate as a class in teacher-directed lessons. (SED)

Argues that an educational perspective is required for examining how second language acquisition (SLA) can contribute to language pedagogy (LP). Different models of application are considered, reflecting different ways of viewing teaching. It is suggested that SLA constitutes a source of "provisional specifications" that practitioners can evaluate…
