Question

Quizplus · Accepted Answer

As a split-brain patient, the left hemisphere of Tracy's brain (which controls language) will not have access to the image of the fork presented on the right side of the screen (which is processed in the left hemisphere). However, the right hemisphere (which processes visual information but does not have language abilities) can still perceive the image of the fork. Therefore, Tracy will be able to verbally name the object as her left hemisphere receives information from her right hemisphere.
