Dr. Elika Bergelson's research lab at Harvard University focuses on how infants learn language, particularly how they understand words before they can say them. The lab investigates the interplay between social behavior and cognitive development during early childhood, with an emphasis on understanding children's language comprehension. This work aims to improve early diagnosis and interventions for children with language delays or disorders, specifically by exploring the key factors that help older infants learn words more effectively than younger ones.
