Personal Statement

My work aims to find the optimal instructional conditions for L2 learning to take place. This involves the investigation of the relative effects of different types of instruction on second language development, as well as the investigation of various factors that may moderate such effects. The research methodology I have most frequently followed involves isolating at least one independent variable from other potential factors and studying its effect on learners' performance on a predetermined target language feature under controlled laboratory settings. Two broad questions that have guided my research program so far are the following: 1) What type of instruction is most effective? 2) Which a) contextual, b) psycholinguistic, and c) cognitive individual difference factors moderate the effectiveness of instruction?

More specifically, I have investigated whether the effectiveness of negative feedback depends on factors such as feedback characteristics (implicit versus delayed feedback), communication mode (computer-mediated communication versus face to face communication), target form salience, and feedback timing (immediate versus delayed). I have also been interested in the relationship between learners' cognitive abilities (e.g., language analytic ability, working memory) and the effectiveness of negative feedback. Currently, in a project funded by the Spencer Foundation, I am examining the relative effectiveness of two instructional interventions (explicit and implicit oral corrective feedback) as a function of different language aptitude profiles that combine cognitive aptitudes for implicit and explicit learning.

The learning of second and foreign languages is a rich and fascinating process involving linguistic, psychological, cultural, and social dimensions. The Indiana University Department of Second Language Studies is dedicated to teaching and research on the structure, acquisition, and use of nonnative language in both instructed and contact contexts.
