Final answer:
Split-brain patients can easily name objects in their right visual field because the left hemisphere, responsible for language, processes this information. They struggle to name objects in the left visual field due to the separation of the hemispheres. They can, however, pick these objects with their left hand, indicating nonverbal processing by the right hemisphere. The correct option is C.
Step-by-step explanation:
The correct answer to the question is c. They can easily name objects in their right visual field. This phenomenon occurs in split-brain patients because when an object is presented to the right visual field, the information is processed by the left hemisphere, which typically houses the speech and language centers.
As a result, the patient can verbally identify objects seen on the right side. However, when an object is presented to the left visual field, these patients struggle to name the object due to the severed corpus callosum, which prevents the visual information received by the right hemisphere from communicating with the language centers in the left hemisphere.
Despite this, split-brain patients can often select an object with their left hand when it is presented in their left visual field as this action is controlled by the same right hemisphere that processes the visual input. This showcases the remarkable but separate abilities of the two hemispheres in split-brain individuals.
