Welcome to the Object Perception Lab!

OPL is Dr. Isabel Gauthier’s research group at Vanderbilt University, located in Wilson Hall on the Vanderbilt University Campus in Nashville, itself located on native Cherokee, Choctaw, Chickasaw, Creek and Shawnee land. We study how humans learn to categorize, recognize and represent objects in different domains. We are particularly interested in the acquisition of perceptual expertise, reflected by unusually good performance that generalizes to objects in an entire category (e.g., letters, faces, birds, cars, musical notation…). Expert performance is generally quite automatic and often accompanied by a loss of flexibility in the perceptual strategies that experts can apply to their trained domain.

Examples of current projects include the study of individual differences in tactile perception, the processing of musical notation or images of food and decisions about medical images. We investigate the structure of abilities supporting both single object recognition and ensemble perception. We are also exploring the structural and functional correlates of visual abilities in the brain.
