Question

Quizplus · Accepted Answer

Since Susan is a split-brain patient, the information from her left visual field (which is processed by the right hemisphere) cannot be communicated to her verbal, language-processing left hemisphere. Therefore, when asked what she sees, she will only be able to respond based on the information processed by her left hemisphere, which is the volleyball in her right visual field. Her response will be "I see a volleyball."
