Face and Object Recognition

One explanation for category specificity in the brain is that some biologically relevant categories are specialized for particular kinds of content. Research supports this explanation and shows selectivity for object categories such as faces, bodies, buildings, words, animals, objects, and tools. This research has provided insight as to how face recognition differs from general object recognition. This approach also can explain selectivity in impairments following brain damage, but does not address how category specificity arises, or how category selectivity changes with experience. In the Beyond Categories lab, we embrace an alternative process-based explanation that conceptualizes category specificity as an emergent property of a distributed and dynamic system that depends on experience, rather than as a result of brain regions that are dedicated to particular categories.
