Lexical acquisition and processing

This series of studies asks how young children discover the meanings of new words, and how they set down and later retrieve their lexical representations for these words. I am particularly interested in verb learning, both because it poses special challenges for learning, and because linguistic context is known to play an important role in how they discover verb meaning. This work uses eye-tracking methods to discover how children interpret new words as the linguistic context unfolds. We study children acquiring English as well as languages with very different linguistic properties from English (e.g., Mandarin, Korean) to see how cross-linguistic differences affect the trajectory of acquisition.

Lexico-semantic/-syntactic representation and processing in adults

This work asks fundamental questions about semantic representation and processing. In one line of work, I explore a phenomenon common to many languages in which one can cancel the endstate of a telic perfective predicate, e.g., I ate the apple but didn’t finish it. Experimental studies on Hindi add new insight to what these predicates mean and what situations allow for endstate cancellation.

Lexical representations in patients with Alzheimer’s disease

The semantic deficits that accompany Alzheimer’s disease are poorly understood. I am interested in what those deficits reveal about the organization of lexical knowledge, particularly for verbs.

Discourse and pragmatics

These studies focus on different languages and different phenomena, but most examine the interaction between the form of referring expressions in a discourse and processing considerations.
