Recently there have been considerable advances made in understanding the kinds of processes which underlie our ability to recognize and name visually presented objects. These advances have come from experimental psychology, from studies of computer vision and from studies of the effects of brain damage on object recognition and naming. This book draws together research from these different approaches to visual object processing in an attempt to relate evidence from disorders of object processing to models of normal performance, and how such models can in turn help us understand object processing disorders.
