Welcome to the Child Language Lab at Boston University!

We are a research group studying language acquisition and language processing. We are interested in questions like:

  • How do children discover the meanings of words?
  • How does the way in which we talk to children affect the way they learn?
  • How does word learning differ in children acquiring languages other than English?
  • How is word learning the same or different in late talkers and children with autism spectrum disorder?
  • How do we rapidly process the language we hear?

We use a variety of behavioral methods, and primarily eye-tracking, to answer these questions in infants, toddlers, and preschoolers, as well as in adults. This research interfaces with linguistics, cognitive and developmental psychology, and communication sciences and disorders.


This research has been funded by the National Institutes of Health (K01 DC013306, R03 HD067485), American Speech-Language-Hearing Foundation, Autism Speaks, Charles H. Hood Foundation, Language Learning journal, American Philosophical Society, and Sleep Research Society Foundation, in addition to internal funding from Boston University.
