Since its first adoption as a computational model for language learning, evidence has accumulated that Rescorla-Wagner error-correction learning (Rescorla & Wagner, 1972) captures several aspects of language processing. Whereas previous studies have provided general support for the Rescorla-Wagner rule by using it to explain the behavior of…

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…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

This study investigated the role of corrective feedback timing in the acquisition of Spanish noun--adjective gender agreement. Forty-five learners completed a communicative task via synchronous computer-mediated communication (SCMC) in one of three groups (immediate, delayed, control). The immediate-feedback group received error reformulations…

This study investigated the effects of teaching English prepositions using schematic diagrams inspired by cognitive linguistics in a computer-based tutorial system called the English Preposition Tutor. Training was designed based on the theoretical framework of the Competition Model and a cognitive linguistic analysis of prepositions. Sixty-four…

This study investigated the effects of negative feedback type (i.e., explicit correction vs. recasts), communication mode (i.e., face-to-face communication vs. synchronous computer-mediated communication), and target structure salience (i.e., salient vs. nonsalient) on the acquisition of two Turkish morphemes. Forty-eight native speakers of…

The current study investigated the impact of recasts together with form-focused instruction (FFI) on the development of second language speech perception and production of English /?/ by Japanese learners. Forty-five learners were randomly assigned to three groups--FFI recasts, FFI only, and Control--and exposed to four hours of communicatively…

The present study investigated the effects of two categories of interactional feedback--recasts and elicitations--on learning linguistic forms that arose incidentally in dyadic interaction. The study also identified implicit and explicit forms of each feedback type and examined their subsequent effects immediately after interaction and after 2…
