Research Interests:

My research explores learning in infancy and childhood. When we think about the differences between what infants and adults know, it's apparent that infants need to acquire a tremendous amount of information. This is especially apparent in language, where any utterance might present infants with an opportunity to discover auditory regularities such as phonotactic or prosodic patterns, word forms and word meanings, and syntactic regularties about how to combine words. How do infants master all of this complexity? What learning mechanisms are available to infants, and what are the constraints on these mechanisms?

To answer these questions, experiments in the lab focus on how infants can use statistical information about the patterns in the input: information on how one event (such as a particular sound) might predict subsequent effects. Our research indicates that statistical information plays an important role in many aspects of language learning. I am particularly interested in understanding the similarities and differences between learning from linguistic and non-linguistic stimuli, learning by infants and adults, and the characteristics of the input and the prior experiences that might facilitate or impair learning.
