VAULT Phase 5 for Language Development Disorders

This study is looking at how toddlers with language development disorders learn new words. Researchers are using a treatment called VAULT Phase 5, which helps children learn vocabulary. The main goal is to see if teaching words from categories children already know (like animals) helps them learn more words overall. Children aged 2 to 4 years old who are native English speakers and have certain language delays may be able to join. The study will measure how many words children learn during and after the treatment to see how effective it is. The current status of this study is unclear, and it plans to enroll 32 participants.
