Overview

The goal of this research is to explore abilities to learn word meanings from overheard speech in children with ASD (and, as a control, typically developing children). Specific Aim 3 (Experiment 3): Determine whether children with ASD can learn verbs and pronouns by overhearing. Most prior work on learning from overheard speech has focused on learning nouns that label objects. This experiment extends this work to study other kinds of words.
