The cerebrum is divided into two integrated cerebral hemispheres. Messages are freely and instantly exchanged between these two areas across a structure known as the corpus callosum. In a sense, the hemispheres receive information about the world in duplicate: information within the right hemisphere is immediately flashed to a corresponding area in the left and vice versa. However, the two hemispheres are not identical twins. While information is duplicated, it may not be processed in the same way. Each hemisphere controls the opposite side of the body and has its own specialized functions. In the examples below, identify whether the abilities being measured are related to the functioning of the right hemisphere, left hemisphere or both. 4. The last portion of the test assesses manual dexterity in the nondominant arm and hand. Since the boy is left-handed, he is required to perform all sorts of mechanical tasks with his right hand. He fails this part of the test miserably, not completing a single task.
