The Navigation test consists of an 8x8 matrix of small pieces of cheese and a mouse. The computer instructs the subject to move the mouse in one of eight possible directions to “eat” the corresponding piece of cheese: Up, Right-up, Right, Right-Down, Down, Left-down, Left, and Left-up. The instructions are given both visually (with the aid of a small arrow) and/or orally. For the tests reported here the instructions were given only orally. The software measured the total number of correct responses and the total number of correct responses divided by total number of trials. | The Navigation test consists of an 8x8 matrix of small pieces of cheese and a mouse.
