About the Lab

Young children learn the meanings of thousands of words by the time they can run down the street. The computational problem they solve is daunting: extracting discrete word forms from a sequence of continuous speech signals and mapping these forms onto their meanings. Yet, the same children who solve this problem continuously forget where they left their coats and hats. How do children learn language so quickly despite cognitive constraints on memory, attention, and information processing?

Our work tries to resolve this puzzle by reframing language acquisition as a coordination problem. The problem is not how children learn language, but how parents and children construct it together.

We analyze this coordination by taking an end-to-end approach to understanding early language acquisition, studying it at multiple levels. Our first line of work investigates the representations and algorithms that children and adults bring to the learning problem. Our second line of work investigates the natural ecological contexts in which language acquisition occurs. Finally, our third line of work uses computational models to formalize the interactions between learner and environment. Successes and failures of language learning emerge from the match (or mismatch) between the learning mechanisms available to the child and the structure of the learning environment.

Empirical Studies

Empirical studies of children's developing mechanisms for learning language.

Corpus Analyses

Corpus analyses of children's linguistic enviroments let us determine what kind of information is available to learn from.

Computational Models

Computational models let us combine the the behavior we observe in the lab with the environmental structure we observe to draw inferences about children's learning.
