A split-brain patient will not be able to verbally identify a picture that is flashed to the left visual field (and therefore processed in the right hemisphere) but will be able to pick up the pictured object with his or her left hand.

Question

Quizplus · Accepted Answer

In split-brain patients, the left hemisphere is usually dominant for language, and the right hemisphere is usually dominant for spatial processing. Due to the lack of communication between the two hemispheres in these patients, information presented in the left visual field will be processed by the right hemisphere, which cannot verbally communicate with the left hemisphere. However, the right hemisphere can control the left hand, so the patient will be able to pick up the object with their left hand.
