Learning the rules: The acquisition of morphological regularities in language
Research demonstrates that infants begin learning words during the first year of life (e.g., Bergelson & Swingley, 2012). Yet, learning a language requires more than simply building a vocabulary; learners must also learn the morphological rules and regularities of their language. In a series of studies at different points of development, and using a range of behavioural and neuroimaging methodologies, I investigate how infants learn morphology. I will present research from neonates, showing the constraints humans may have on processing regularities in speech from birth. Then I will show evidence from 9- to 24-month-old Italian-learning infants demonstrating their ability to find the regularities in their language and map those regularities to the conceptual distinctions that they highlight.
