Researchers took photographs of different faces,cut them in two,and pasted different halves together to form composite faces.The reconstructed photographs were flashed quickly to split-brain patients.It was found that the split-brain patients would:
A)name the person in the left part of the image and point with the right hand to the left image.
B)name the person in the right part of the image and point with the left hand to the left image.
C)name the person in the right part of the image and point with the right hand to the left image.
D)name the person in the left part of the image and point with the left hand to the right image.

When the brain's hemispheres are split, the left visual field goes to the right hemisphere and the right visual field goes to the left hemisphere. Therefore, when split-brain patients were shown a composite face with the left half in the right visual field and the right half in the left visual field, they were only able to verbally identify the person on the right side of the image (which went to the left hemisphere, responsible for language processing) and point to the left side of the image (which went to the right hemisphere, responsible for motor control of the left hand). Therefore, the answer is B, which indicates naming the person in the right part of the image and pointing with the left hand to the left image.
