I am broadly interested in perception and cognition, and how they change (or don’t) during childhood. My work focuses on how children represent space in the world around them, and how they use their understanding of spatial information to help learn what numbers are and how to use them. Similarly, I am interested in how children use spatial representations to understand how objects move in the world (‘intuitive physics’) and how to move them in their mind (‘mental rotation’). My research program uses both behavioral and neural (fMRI) methods, in both young children and adults.
