he 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. 1. A nine year old with several problems, but who is thought to be gifted, has been referred for testing by his teacher. One portion of the test assesses his ability to read and apply detailed instructions regarding geometrical forms, for example, "Put the red trapezoid inside the blue hexagon under the orange parabola." To the delight of his teacher, he performs these tasks perfectly.
