Final answer:
In split-brain patients, touching something with the left hand that is unknown but familiar will result in the inability to verbally identify it due to the speech center being on the left side of the brain. However, the patient can still recognize and pick up the object with the left hand controlled by the right hemisphere.
Step-by-step explanation:
When a patient with a split brain condition, where the corpus callosum is cut, touches something with their left hand that is unknown but familiar, they will be unable to verbally identify it due to the speech center being located in the left side of the brain. However, they will still be able to recognize and pick up the object with their left hand, controlled by the right hemisphere. This demonstrates the unique functions of the two hemispheres of the brain in split-brain patients.
