( Associative, Apperceptive ) agnosia refers to a failure of recognition due to defective retrieval of knowledge pertinent to a given stimulus. The problem is due to faulty sensory-specific memory; the patient is unable to recognize the object despite being able to perceive it normally. ( Apperceptive, Associative ) agnosia refers to a defective integration of otherwise normally perceived components of a stimulus. The problem is more a failure of perception; these patients fail to recognize a stimulus because they cannot integrate the perceptual elements of the stimulus.

Many patients with focal damage to the can still recognize single faces, words, objects etc as well as cognitively intact persons. Memory requiring relationships between single stimuli requires the . This division of labor explains the severity of memory disorder resulting from these lesions. Even when amnesic patients retain some new learning ability, this new information lack superordinate organizing context.
