Dissociation of color from object in amnesia

Department of Neurology, University Hospital, Zurich, Switzerland.
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.
