Our laboratory studies how people visually categorize, identify, and recognize objects. We examine how objects are processed and represented by the visual system, how visual knowledge about objects is represented and learned, and how perceptual decisions about objects are made. We are particularly interested in the temporal dynamics of visual object recognition. That includes the short-term dynamics of an individual decision about an object’s category or identity and the long-term dynamics of how those decisions change with learning and perceptual expertise. We approaches these questions using a combination of behavioral experiments, cognitive neuroscience techniques, and computational and neural modeling.
