a set of standardized procedures for assessing neuropsychological disorders of visual object recognition which includes tests to assess low-level aspects of visual perception (using same-different matching of basic perceptual features, such as orientation, length, position and object size), intermediate visual processes (e.g., matching objects different in viewpoint), access to stored perceptual knowledge about objects (object decision), access to semantic knowledge (function and associative matches) and access to names from object (picture naming).
