By the time they reach the preschool period, most children speak in full sentences, and the building blocks of this skill are in place long before that. My research examines how children accomplish this. How do infants and toddlers learn to recognize words from fluent speech? How do they learn to process the relationships between words in a sentence? And, most importantly, how do children use this acquired linguistic knowledge during language processing in their daily lives? Ultimately, my work aims to provide a better understanding of the developmental trajectory of spoken language processing from infancy to adulthood.
