Final answer:
A patient with a severed corpus callosum will most likely be able to pick out an object presented in the left visual field with her left hand but will not be able to verbally identify it due to the disconnection of hemispheres. Correct option is 4)
Step-by-step explanation:
When a patient with a severed corpus callosum is presented with an object in the left visual field, she will most likely be able to pick out the object with her left hand. The reason for this ability is due to the manner in which information travels within the brain once the corpus callosum is cut. Visual input from the left visual field is processed by the right hemisphere, which controls the left side of the body. However, because the speech centers are generally located in the left hemisphere and are no longer able to receive information from the right hemisphere, the patient will not be able to verbally identify the object. Therefore, the most accurate response from the options given is: 4) pick out the object with her left hand.
