About this trial
Many children have developmental language disorder, which makes it difficulty to learn language, including vocabulary, and results in ongoing academic and social difficulties. Despite the fact that most words are learned in context without direct teaching, we know very little about how children with developmental language disorder learn words in context. This project will combine, for the first time, two strategies which improve contextual word learning in children with typical development, and test their effect in both typically developing children, and those with developmental language disorder. The results will provide timely information that will contribute to evidence based practice for contextual word learning in children with developmental language disorder.
