Visuomotor adaptation has been thought to be an implicit process that results when a sensory-prediction error signal is used to update a forward model. A striking feature of human competence is the ability to receive verbal instructions and employ strategies to solve tasks; such explicit processes could be used during visuomotor adaptation. Here, we used a novel task design that allowed us to o...

The goal of this thesis is to explore how foreign language learning can be facilitated through the use of intelligent computer-assisted language learning (ICALL) based on natural language processing (NLP) methods. ICALL was provided in the form of a task-based dialog system that gives corrective feedback.We investigated how different parameters of the interaction affect the learning progress. B...

although explicit and implicit knowledge of language learners are essential to theoretical and pedagogical debates in second language acquisition (sla), little research has addressed the effects of instructional interventions on the two knowledge types (r. ellis, 2005).this study examined the relative effectiveness of explicit and implicit types of form-focused instruction (ffi) on the acquisit...

The debate on grammar in second language acquisition: past, present, and future, is a well written summary of both explicit and implicit grammar instruction in second language acquisition from past to present and with future projections. The thesis holds that explicit grammar instruction plays a very important role in foreign language learning and teaching and argues that English education in C...

Development of explicit phonological awareness (PA) is thought to be dependent on formal instruction in reading or spelling. However, the development of implicit PA emerges before literacy instruction and interacts with how the phonological representations are constructed within a certain language. The present study systematically investigated the development of implicit PA of Mandarin onset-ri...

One of the most heavily debated questions in implicit social cognition is the extent to which implicit measures can be voluntarily controlled. The experiment reported here is the first to employ a novel strategy for intentionally controlling performance in the autobiographical Implicit Association Test (aIAT). Specifically, when explicitly instructed to do so, participants were able to speed up...

The distinction between implicit and explicit retrieval of learned material is central to recent thinking about the neural systems underlying memory. Word stem completion is one task in which subjects can be instructed either to make a deliberate recall (explicit instruction) or to be told to complete the stem with any appropriate word (implicit instruction). Positron emission tomography (PET) ...
