Study Summary
The goal of this clinical trial is to compare two treatment conditions for late talking toddlers. In 8 weeks of word learning treatment, toddlers will be taught words that sound more like the words they already know or sound less like the words they already know. The investigators see which group learns more, to understand if choosing words that let children use the knowledge they already have helps with learning.
Primary Outcome
The investigators will count the number of spontaneous and probed productions of target and control words and calculate a treatment effect size (d).
