My research examines the development of 3D object recognition, and my specific interest is in how infants, children and adults learn to understand that novel objects are structurally coherent in three dimensions and continuous in space and time. This research relies on a combination of behavioral measures, eye-tracking, and brain imaging techniques to investigate the nature and development of mechanisms underlying our perception of 3D objects. Current projects are evaluating how young children and adults arrive at a conceptual understanding of the pictorial dimensions and geometric properties, such as symmetry, complexity, and possibility (vs. impossibility) that characterize real objects.
