When a picture is flashed to the left visual field, it is processed by the right hemisphere of the brain, which is responsible for nonverbal processing. When a picture is flashed to the right visual field, it is processed by the left hemisphere of the brain, which is responsible for verbal processing. In a split-brain patient, there is limited communication between the two hemispheres of the brain, so the patient can only verbally identify the picture that was presented to the left visual field, which in this case is the cat. The picture of the dog presented to the right visual field will not be verbally identified.
