Can personalized recall timing boost word learning in kids with DLD?
NCT ID NCT06995014
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This study explores whether tailoring when children with developmental language disorder (DLD) practice recalling new words can improve their learning. Researchers compare a standard fixed schedule to an adaptive one that adjusts to each child's progress. Four- and five-year-olds with DLD learn novel nouns and are tested on recall and recognition shortly after and one week later. The goal is to see if the adaptive approach leads to better word retention.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Behavioral intervention comparing adaptive vs. standard retrieval practice schedules for word learning
- What this could lead to
- If adaptive retrieval helps children with DLD learn words better, it could lead to more effective speech therapy techniques.
- What could go wrong
- This is a small early study with only 7 children, so results may not apply broadly. The intervention is behavioral and may not produce lasting gains.
