High-level vision and categorization in humans

Research Summary:

Dr. Tarr's research explores how humans visually perceive learn, process, recognize, and remember objects and faces. Over the years he has used a wide variety of techniques, including "computer-graphics" psychophysics, fMRI, DSI, ERP, MEG and computational modeling, as well as collaborating with other labs who use neuropsychological case studies and neurophysiological recordings.

Current research interests focus on the compositional feature code used to represent objects in human IT, on the origins of category-selective responses in human IT, and on interactions between the ventral visual stream and other processing systems (e.g., affective, dorsal, or semantic). Specific methods in use or under development include real-time, adaptive fMRI, high-density fiber tracking based on DSI, and aligned MEG/fMRI. Consistent with the open source model, the Tarr lab maintains an extensive stimulus archive provides access to their own collection of faces, familiar objects, and novel objects. The archive is a component of the Center for the Neural Basis of Cognition's much larger stimulus archive. Further information of potential use may be found on the software page detailing information about running and analyzing experiments using OS X.
