Professor Jeffrey J. Lockman got his Ph.D at the University of Minnesota. His research interests center on perception-action and cognitive development. In his recent work, he has been studying the development of tool use in children and how it might be related to the object manipulation skills of infants. Additionally, he has been conducting work on spatial cognition in children, focusing on how children code the location of objects and object features.
