Test Nine: Visual Digit Span

The number of trials for this test depends upon the patient's ability to remember a sequence of digits. To begin the test, click on the button labeled "Digit Span." At the beginning of the test, the computer visually presents three digits. Next, a dialog box appears that reads, "What did you see?". The patient may tell you the digit she or he saw for you to type, or you may allow the patient to type his or her own response. Be certain that the numbers entered match how the patient remembers the sequence. Correct mistakes with the "Delete" key. If the patient responds correctly, the computer adds one digit to the length of the next sequence. On the other hand, the computer subtracts one digit from the length of the next sequence if the patient responds incorrectly. The test continues in this fashion until the patient makes five errors. For each trial, write down the total number of digits presented, rather than the actual sequence of numbers presented.

Test Ten: Delayed Face Recognition

This test consists of five trials. The computer randomly presents 12 faces serially at one per 2 s. Treat this section just like Test Three. The patient should give one of the same Test Three responses for each face. Under the column labeled "Face," write the initials of each face using the initials provided in Appendix A and use a "¯" or "-" for recognition and naming. Please engage the patient in small talk during the 30 second delay to prevent rehearsal of the faces. Following the distraction, the patient will see four faces and must say "old" for previously presented faces or "new" for initially presented faces (no face naming in this part). On the score sheet, write down the face initials again and an "O" or an "N" under the "O/N" column. Write down what the patient says even if it is incorrect.

Test Eleven: Delayed Object Recognition

This test consists of ten trials similar to the previous test. During each trial, the computer presents an object on the screen for three seconds, after which follows a 14 second delay. Instruct the patient not to name the item. Again, small talk with the patient during the delay improves the test procedure. Then, the computer presents four objects, one at a time. The patient must say "new" for previously unseen objects or "old" for the initial target object. Write an "O" or an "N" in the proper column for each reply. Again, write down what the patient says even if it is incorrect.

Test Twelve: Lexical Recognition

This test mimics Test Five, but uses three speeded trials words instead of objects. Administer and record it just like Test Five.
