Visual Object Agnosia
Visual agnosia is a deficit in recognition that is not due to impairment of vision or memory.[1] Apperceptive recognition includes the visual information from the retina being put together to create a perceptual representation while associative recognition means the meaning of an object is attached to the perceptual representation. If someone can perceive the form of an object and has knowledge about it but cant identify it, this is associative agnosia.[2] However, if they are unable to recognise it because they cannoy perceieve the form, it is apperceptive agnosia. Visual agnosia is generally due to bilateral damage in the posterior occipital and/or temporal lobe/s in the brain.
