Final answer:
Split-brain patients are tested using experiments like the visual cross-cuing test and the tactile naming test.
Step-by-step explanation:
Split-brain patients are tested to see what information each hemisphere gets through various experiments. One common experiment is the visual cross-cuing test, where different visual stimuli are presented to each eye and the patient is asked to respond accordingly. For example, an object may be shown to the left eye, which sends information to the right hemisphere, and the patient is asked to identify it using their left hand. Another test is the tactile naming test, where different objects are placed in the patient's left and right hands, and they are asked to name what they feel using their left or right hand accordingly.
