Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are school-age children aged 8-11 with diagnosed developmental language disorder and specific language impairments.

Probably not a fit

Patients with neurodevelopmental disorders, emotional or behavioral disorders, or those who have received prior treatment for complex syntax may not benefit from this study.

What this trial studies

This project aims to compare the effectiveness of two innovative treatments designed to enhance complex grammar knowledge in school-age children (ages 8-11) with developmental language disorder (DLD). One treatment employs an implicit approach, where children listen to target sentences multiple times during training, while the other uses a conventional explicit method that teaches grammar rules directly. The study will conduct two randomized clinical trials focusing on different syntactic structures to evaluate the outcomes of both treatment methods. By controlling key treatment aspects, the researchers hope to determine which approach yields better results in improving grammar skills.

Why it matters

Potential benefit: If successful, this study could significantly enhance the grammar skills of children with developmental language disorders, leading to improved communication abilities.

How similar studies have gone: While there have been few treatment studies for later-developing language skills, this approach is novel and aims to address limitations seen in previous research.
