Dissociation of color from object in amnesia

Arch Neurol. 1992 Sep;49(9):982-5. doi: 10.1001/archneur.1992.00530330106026.


A patient with persistent amnesia after bilateral medial temporal and left inferotemporo-occipital infarction could not match colors to objects in verbal, visual, or visuoverbal tasks. A severe naming disorder for objects was present but the patient could name colors and point to colors whose name was given. The matching disorder appeared to be a deficit in the semantic classification of objects rather than a problem in identifying colors.
