| Summary | The goal of this clinical trial is to compare the efficacy of explicit vs. implicit intervention on subject relative clause production in Cantonese-speaking children with Developmental Language Disorder (DLD). It will also learn about individual difference predictors of intervention outcomes. The main questions it aims to answer are: 1. Will the explicit intervention (Shape Coding+syntactic priming) on relative clause production lead to better outcomes than implicit intervention (syntactic priming only)? 2. Can pre-intervention procedural learning, working memory (WM) capacities, and grammar impairment severity predict the intervention outcomes across children with DLD? 3. Will 10 intervention sessions (500 doses of the target structure) lead to learning progress in children with DLD, even |
