A patient has difficulty identifying partially obscured objects after a stroke. Which cognitive-perceptual skill should be addressed to improve object identification?

• A. Stereognosis
• B. Visual closure
• C. Spatial relations
• D. Figure-ground

Answer: (B)

Visual closure is the ability to mentally complete incomplete visual information to recognize a whole object. When parts of an object are obscured, this skill lets you infer the missing portions and identify the object. After a stroke, this capability can be impaired, leading to difficulty with object identification under partial occlusion. Therapy would focus on exercises that progressively obscure objects, asking the patient to name or match the object, using cues and repetition to train the brain to fill in the gaps. Stereognosis involves recognizing objects by touch without relying on vision, so it's not about visually identifying occluded objects. Spatial relations concerns understanding how objects are positioned in space, not completing partial visual information. Figure-ground involves distinguishing a figure from its background, which can help in cluttered scenes but doesn't directly address completing missing parts to identify objects.
