Question

Brendan Jones · Accepted Answer

Final Answer : B, Explanation :  The corpus callosum connects the two hemispheres of the brain, facilitating communication between them. Damage to this structure can impair the transfer of information. Visual information from the left visual field (where HOUSE was displayed) is processed by the right hemisphere, and information from the right visual field (where BOAT was displayed) is processed by the left hemisphere. Since language processing is typically dominated by the left hemisphere, the man would more likely be able to verbalize BOAT, which appeared on the right side of the screen and thus was processed by his left hemisphere.
