The Effect of Semantic Support on Word Learning

Description

The goal of this clinical trial is to compare word learning outcomes in late talking toddlers who are taught different types of words. The main question it aims to answer is if teaching words that come from categories that children already know (e.g., animals) will aid overall word learning. Children will take part in the Vocabulary Acquisition and Usage for Late Talkers (VAULT) word learning treatment and be taught words from more familiar or less familiar categories to see which group learns more words overall.
