Sandra Waxman: Wizards of Word-Learning: Linguistic and Conceptual Foundations to Infants’ Stunning Success April 12, 2012

Human infants are wizards of word-learning. This talk will describe the conceptual and linguistic capacities that underlie their success. To learn the meaning of any novel word, infants must set their sights in two distinct directions. Facing the conceptual domain, they must identify concepts that capture the various relations among the objects and events that they encounter. Facing the linguistic domain, they must cull words and phrases from the melody of the human language in which they are immersed.

Findings from our laboratory, among others, have revealed that even before they begin to speak, infants’ advances in each of these domains are powerfully linked. This talk will argue that infants begin with a broad universal initial link between the linguistic and conceptual systems, and that this sets the stage for increasingly precise links between different kinds of words (e.g., noun, verb) and different kinds of meanings. New evidence from infants as young as 3- and 4-months of age will also be presented. Together, the work reveals that throughout development, naming is a powerful engine, fueling the acquisition of the essential, rich relations that characterize our most powerful concepts.
