Associative agnosia is a form of visual agnosia in which a person correctly perceives the shape and form of an object, and retains general knowledge of what such objects are, yet is still unable to identify or name the specific object in front of them. It is one of the two classic subtypes of visual agnosia, which results from damage to the brain's visual association areas rather than the primary visual cortex; unlike the other subtype, apperceptive agnosia, in which the perception itself is faulty, associative agnosia involves intact perception with a failure at the later stage of assigning meaning to what is seen.
