Quizplus · Accepted Answer

When an object is presented in the right visual field, it is processed by the left hemisphere of the brain which controls the right hand. Therefore, the split-brain patient would be able to pick out the object with their right hand. They would not be able to verbally communicate what the object is because the left hemisphere, responsible for language and speech, does not have access to the visual information presented in the right visual field.
