Comparing explicit and implicit language interventions for Cantonese-speaking children with language disorders

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effectiveness of explicit versus implicit interventions on the production of relative clauses in Cantonese-speaking children diagnosed with Developmental Language Disorder (DLD). The study will utilize a randomized controlled trial design to compare two intervention methods: an explicit approach that combines Shape Coding and syntactic priming, and an implicit approach that uses only syntactic priming. Additionally, the trial will investigate how individual differences, such as procedural learning abilities and working memory, may predict the outcomes of these interventions. The researchers will conduct ten intervention sessions to assess learning progress and potential plateaus in language development.
