While previous research has shown that processing instruction (PI) can more effectively facilitate the acquisition of target structures than traditional drill practice, the processing mechanism of PI has not been adequately examined because most assessment tasks have been offline. Using eye-tracking, this two-experiment study compared changes in…

In this study we examined language learners' attentional processing of a target syntactic construction in written L2 input in different input conditions, the change in learners' knowledge of the targeted construction in these conditions, and the relationship between the change in knowledge and attentional processing. One hundred L2 learners of…

Williams's (2005) study on "learning without awareness" and three subsequent extensions (Faretta-Stutenberg & Morgan-Short, 2011; Hama & Leow, 2010; Rebuschat, Hamrick, Sachs, Riestenberg, & Ziegler, 2013) have reported conflicting results, perhaps in part due to differences in how awareness has been measured. The present…

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…

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…

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…

Building on the cognitive and interactive perspectives of task research, the cognition hypothesis states that increasing task complexity promotes greater interaction and feedback and thus facilitates second language (L2) development (Robinson, 2001b, 2007a). To date, very little research has explored this claim during learner-learner interactions…

This article examines whether there is any difference between the effect of oral and written corrective feedback (CF) on learners' accurate use of English articles. To this end, the current research presents the results of a quasi-experimental study with a pretest, immediate-posttest, delayed-posttest design, using 12 intact intermediate…

This study investigates the effects of meaningful input- and output-based practice on SLA. First-semester Spanish students (n = 45) were assigned to processing instruction, meaningful output-based instruction, or control groups. Experimental groups received the same input in instruction but received meaningful practice that was input or output…
