Introduces research on a fundamentally unique human ability: learning language. Covers how young children first learn about their native language, including (1) how children figure out what sounds their language includes; (2) how infants learn words and their meanings and (3) what kind of processes help babies figure out the grammar of their particular native language. Since young children understand more than they can say, the course also covers the methods available for figuring out what kids know, based on experimental and observational data. Students will discuss and present recent research articles and new study ideas. Open to graduate students with relevant background. Instructor consent required.
