Wikipedia
Visual agnosia
Visual agnosia is an impairment in recognition of visually presented objects. It is not due to a deficit in vision (acuity, visual field, and scanning), language, memory, or intellect. While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as the posterior occipital and/or temporal lobe(s) in the brain.[2] There are two types of visual agnosia: apperceptive agnosia and associative agnosia. Recognition of visual objects occurs at two primary levels. At an apperceptive level, the features of the visual information from the retina are put together to form a perceptual representation of an object. At an associative level, the meaning of an object is attached to the perceptual representation and the object is identified. If a person is unable to recognize objects because they cannot perceive correct forms of the objects, although their knowledge of the objects is intact (i.e. they do not have anomia), they have apperceptive agnosia. If a person correctly perceives the forms and has knowledge of the objects, but cannot identify the objects, they have associative agnosia.

visual agnosia
Visual agnosia is a neurological disorder characterized by an individual's inability to recognize and interpret visual information, despite having normal eyesight. It is caused by damage to certain areas of the brain that are responsible for visual processing and perception. This condition can affect a person's ability to recognize objects, faces, colors or places, even though they can see them clearly.

Visual agnosia
Visual agnosia is an impairment in recognition of visually presented objects. It is not due to a deficit in vision, language, memory, or low intellect. There are two types of visual agnosia: apperceptive agnosia and associative agnosia. Recognition of visual objects occurs at two primary levels. At an apperceptive level, the features of the visual information from the retina is put together to form a perceptual representation of an object. At an associative level, the meaning of an object is attached to the perceptual representation and the object is identified. If a person is unable to recognize objects because he cannot perceive correct forms of the objects, although their knowledge of the objects is intact, it is apperceptive agnosia. If a person correctly perceives the forms and has knowledge of the objects, but cannot identify the objects, it is associative agnosia. Visual agnosia is often due to bilateral damage in the posterior occipital and/or temporal lobe in the brain.
