How much do infants know about the world in which they live? At what age do humans begin to develop an understanding of object permanence and of the reality that people act in response to different things around them? These are the kinds of questions Yuyan Luo, Assistant Professor in the Department of Psychological Sciences, seeks to answer. In addition to teaching cognition development courses—from infancy to toddler—she runs the Infant Cognition Lab, which tests psychological and biological knowledge development through a series of lab experiments. Now in its second year of operation, the lab conducts experiments with participants as young as two and one-half months old.
Luo describes her current research project, which focuses on determining infants’ knowledge of psychological reasoning. Using the looking-time method, she is testing infants as young as three-months old to see if they understand the concept of object preference.
