Apperceptive and Associative Visual Agnosia in Prosopagnosia

topic
(Writing from two dimensions, first, roughly what are the two agnosias, and then write the difference in facial agnosia)
Brain damage can sometimes cause obvious and specific obstacles in behavior. One of the extremely rare cases is that they can't recognize everyday items after seeing them. This kind of disorder is called visual agnosia. (Visual agnosia includes all minor visual object recognition disorders, and does not refer to cognitive vision therapy or cognitive impairment, such as language or other memory). The occipital lobe is the center of the visual cortex, which is mainly related to visual perception and visual memory. The lesions in the 18th and 19th areas cause visual agnosia. The main causes of agnosia are intracranial tumors, cerebrovascular diseases, and traumatic brain injuries (citation: ). Including object agnosia, appearance agnosia, simultaneous agnosia, color agnosia, visual space agnosia, etc. For example, a patient with object agnosia cannot recognize common objects that he sees clearly, such as hats, gloves, pens, etc (citation: ). This article will explain the two main types of visual agnosia, apperceptive agnosia, and associative agnosia, and case studies will be proved to demonstrate the symptoms of the two types of visual agnosia. （You can modify it to add some content about facial agnosia)
Visual apperceptive agnosia defines as a patient who has intact fundamental visual processing but the patient has impaired higher-level visual processes result in difficulty recognizing an object. (Grossman, Murray, et al. “Object Recognition Difficulty in Visual Apperceptive Agnosia.” Brain and Cognition, Academic Press, 25 May 2002, www(dot)sciencedirect(dot)com/science/article/abs/pii/S0278262697908769). Causes, symptoms of behavior, interspersed with casestudy.
Associative agnosia refers to an obstacle that "can extract normal visual representations but cannot identify objects with this information". Its performance is that it can recognize two identical objects, but cannot tell the function of the two objects (Patients can recognize that the objects in the two pictures are the same, but cannot understand the purpose of the objects). Associative agnosia is the impaired function of recognizing the meaning of objects. Location, damage to the brain, and what are the symptoms of behavior. Interspersed with casestudy.
Specifically speaking, the difference between these two diseases is similar. Need some experimental literature, (you can try copying line drawing)
The manifestations, symptoms, and causes of facial agnosia, compare the differences between appercetive agnosia and associative agnosia in facial agnosia, casestudy.
Usable citation: At the level of form perception, he proposed that visual recognition required processing through two distinct stages: the first (apperception) he described as “the stage of conscious awareness of a sensory impression”; the second (or associative stage) was believed to result from the simultaneous activation of many concepts related to the object (ie, the activation of associated memories)
