What this research studies

If your child has developmental language disorder (DLD), researchers will compare two ways caregivers can provide language support: dose-controlled, therapist-style recasts and more typical caregiver book-reading using illustrated syntax stories. Children and their caregivers will be followed to see how faithfully each approach is delivered and how that affects children’s ability to understand and produce complex grammar. The team will measure both comprehension and production outcomes under ideal (controlled dose) and typical (variable dose) conditions. Methods include caregiver instruction, repeated story exposures, and standardized language measures over time.

Who could benefit from this research

Good fit: Ideal candidates are children with diagnosed developmental language disorder who are past toddlerhood (e.g., older than about 3 years) and not yet fluent readers, along with a caregiver able to participate in home-based reading or intervention activities.

Not a fit: Children without DLD, children who are already fluent readers, or families unable to implement caregiver-guided activities are less likely to benefit from this project.

Why it matters

Potential benefit: If successful, this work could identify a more practical, widely usable way for caregivers to boost grammar skills and school readiness in children with DLD.

How similar studies have performed: Previous work has shown promise for illustrated syntax story approaches in improving passives and other complex forms, while caregiver recasts are a common therapy approach but can be hard to deliver consistently in routine care.
