What this trial studies
This project investigates the word learning abilities of four- and five-year-old children with developmental language disorder (DLD). It compares two retrieval practice schedules: a standard repeated spaced retrieval schedule and an adaptive retrieval schedule tailored to each child's knowledge state. The aim is to determine if the adaptive approach enhances word recall and retention more effectively than the standard method. The study is grounded in cognitive psychology principles that emphasize the benefits of retrieval practice for long-term retention.
Who should consider this trial
Good fit: Ideal candidates are preschool-aged children with a significant language ability deficit but without neurological damage or autism spectrum disorder.
Not a fit: Patients who are non-native English speakers or have scores indicating intellectual disability may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly improve vocabulary acquisition and retention in children with developmental language disorder.
How similar studies have performed: Previous studies have shown that retrieval practice can enhance word learning in preschoolers, suggesting potential success for this adaptive approach.
