Inability to demonstrate an accurate percept of objects, with an inability to draw or name objects, is best described as which visual disorder?

• A. Associative visual agnosia
• B. Apperceptive visual agnosia
• C. Prosopagnosia
• D. Agnosia

Answer: (B)

The main idea is a perceptual failure in recognizing and forming a stable representation of objects. Apperceptive visual agnosia arises when early visual processing cannot integrate basic features into a coherent percept, so the person struggles to perceive objects accurately and, as a consequence, has trouble copying or drawing them as well as naming them. Even with intact basic vision (color, brightness, edges), the percept isn’t formed well enough to guide recognition or reproduction. So, when someone cannot drawing or name objects because the percept itself is faulty, apperceptive visual agnosia best fits.

If you consider other possibilities, associative visual agnosia would involve a preserved percept but a failure at linking that perception to meaning, so copying or drawing could be possible even if naming is impaired. Prosopagnosia is specific to faces, not objects. A general agnosia label without specifying the type wouldn’t capture the perceptual integration problem described here.
