Overview
Brief Summary
The goal of this clinical trial is to see if providing late talking toddlers who are not responding to the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment with a different way of communicating will help them improve their word learning. Participants will start with VAULT word learning treatment. If, in the first few sessions, it looks like they won't respond well, they will be provided with a Big Mack Augmentative and Alternative Communication device (a button that says a word when you press it) to use for their responses. The investigators will see if this modification will help with word learning.
Detailed Description
Children will begin Vocabulary Acquisition and Usage for Late Talkers (VAULT) word learning treatment. If, after three sessions, they do not show an initial response to treatment, they will be provided with a Big Mack Augmentative and Alternative Communication device which will allow them to 'say' the treatment words with the device. Treatment will continue until the children have had 8 total weeks of treatment (2x/wk for 30 minutes per session). The investigators will measure word learning across time tracking both spoken productions and productions made with the device.

Outcomes
Primary Outcomes
Treatment Effect Size
Time Frame: Change from baseline through treatment, which will average an 8-week time frame.
The investigators will count the number of spontaneous and probed productions of target and control words and calculate a treatment effect size (d).
Number/Rate of words learned
Time Frame: Change from Initial Evaluation through Follow-up, which will average a 6-month time frame.
The investigators will measure the number of words learned and rate of words learned as reported by the parent on the MCDI starting prior to treatment and measured during, immediately following, and 4-6 weeks after the treatment.
Secondary Outcomes
- Post Treatment Retention(Change from end of treatment to follow up, which will average 4-6 weeks.)
