Research

Trained as cognitive psychologist, my research has touched upon many of the fundamental topics of the discipline, such as memory, attention, and visual perception. A focus of mine has been on the role for eye movements in object and scene perception, particularly the question of how information is maintained and integrated from one fixation to the next. I am currently working with John Philbeck on a neuropsychological study investigating the role for medial temporal lobe in human navigation. We are also collaborating with Stephen Pothier and David Chichka from the Department of Aerospace Engineering, developing an apparatus that allows for masked tachistoscopic exposures of real-world scenes for the purpose of investigating the time course for egocentric distance perception.
