Official title
Identification of Treatment Parameters That Maximize Language Treatment Efficacy For Children
Overview
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.
Detailed description
Children will be assigned to either the familiar or less-familiar word group. All children will receive 8 weeks of Vocabulary Acquisition and Usage for Late Talkers (VAULT) word learning treatment (2x/wk for 30 minutes each session). The investigators will measure how well children learn the words they are taught as well as the words that are in the environment, but not explicitly taught (control words). This will help us know if their learning is due to treatment or maturation. The investigators will compare children to themselves (taught words v. control words) to ensure that the overall treatment is working. Then, the investigators will compare children in the familiar word group to children in the less-familiar word group to see which group learns more overall.
Interventions
- Behavioral VAULT Phase 5
This is an input-based vocabulary learning treatment based on principles of statistical learning.
Primary outcome measures
- Treatment Effect Size [Time frame: Change from baseline through treatment, which will average an 8-week time frame.]
- Number/Rate of Words Learned [Time frame: Change from Initial Evaluation through Follow-up, which will average a 6-month time frame.]
Secondary outcome measures (1)
- Post Treatment Retention [Time frame: Change from end of treatment to follow up, which will average 4-6 weeks.]
