In my research program, I ask how young children discover the meanings of new words (primarily verbs, but also some nouns such as event nominals) what their lexico-semantic and -syntactic representations for these words look like, and how their language processing systems retrieve these representations when they hear the words again. I am also interested in how the properties of parent talk help (or hinder) these abilities. This work uses eye-tracking methods to discover how children interpret new words as the linguistic context unfolds. I study children acquiring English as well as languages with very different linguistic properties (e.g., Turkish, Korean) to see how cross-linguistic differences affect the trajectory of acquisition, and children who are developing typically as well as children with or at risk for language or communication disorders (late talkers, children with autism spectrum disorder).
