Janet Werker Developmental psychologist
Janet Werker studies maturational and experiential factors that make it possible for children to begin learning language, particularly during the first two years of life. She seeks to identify the kinds of perceptual biases infants bring to speech perception, the role that specific linguistic input plays in modifying perceptual categories, how these changing categories help the child move on to acquiring language, and the advances in learning and cognition that contribute to this process. She has identified a number of milestones in early infancy that reveal a child’s progress on this journey of discovery. Her work includes both studies of infants being raised in different language environments, as well as infants growing up in bilingual or multilingual homes. Her work also includes infants who are “at risk” for developmental or specific language delays, to see if the milestones that have been documented in early infancy can be used to help identify children in need of intervention. Her experimental studies use both behavioural and neuroimaging tasks to address these questions. With inspiration and assistance from CIFAR, and in collaboration with others in CIFAR, she now also investigates emotional and pharmacological factors that can change the timing of speech perception development in infancy, and reawaken sensitivity in adulthood.
