Research in the Polka lab focuses on the development of speech perception during infancy. The goal of this work is to understand the skills and biases that the infants bring to this task and how their speech processing changes with age and language experience to support language processing. We are currently engaged in research involving infants between 4 and 18 monhs of age on vowel perception and production, the effects of early bilingualism and the role of attention in speech processing.
