Quizplus · Accepted Answer

Since the man has damage to his corpus callosum, the visual information from the left half of his visual field is processed by the right hemisphere of his brain, and the information from the right half is processed by the left hemisphere. The language centers of the brain are typically located in the left hemisphere. Thus, when asked what he saw, the man would likely only be able to verbally report the object presented on the right side of the screen (beans) and not the object presented on the left (green). Therefore, he would likely reply "Beans."
