Final answer:
Unilateral (left-hand) agraphia is observed in split-brain patients. They can't verbally identify an object presented to their left visual field, but they can still pick it up with their left hand.
Step-by-step explanation:
Unilateral (left-hand) agraphia is a condition observed in split-brain patients. When an object is presented to the patient's left visual field, which is processed by the right hemisphere of the brain, they may be unable to verbally identify the object. However, if asked to pick up a specific object with their left hand, the patient will be able to do so.
