Optimizing feedback-based learning in children with developmental language disorder.

The award funds a research project to improve feedback-based learning in children with developmental language disorder by studying the effects of feedback timing and self-correction on learning outcomes.

Description

This project aims to optimize a critical but understudied ingredient of language intervention provided to children with developmental language disorder (DLD) – feedback. The project is designed to bridge the gap between previous findings in our lab of inefficient feedback processing in DLD and clinical practice by identifying the conditions under which feedback-based learning can be improved in DLD. The project will achieve its aim by manipulating the timing of the feedback and the level of the learner’s involvement in error correction dictated by feedback to modulate the dominance of the implicit and declarative learning systems. The project will determine whether children with DLD learn better when feedback prompts self-correction or when they are exposed to passive corrections, complemented by electrophysiological measures of feedback processing.
