Heads Up / Heads Down Data Sheet

1. Have the test subject sit comfortably in a chair.

2. When everyone is ready the score keeper hands the test subject the deck of 20 flash cards and the timer begins timing. View each flash card until the entire deck (all 20 ) have been shown. The score keeper places the correctly answered cards in one pile and the incorrect ones in another pile.

(For the E search test the subject will respond, "Yes," if there is an E in the sequence and, "No," if there is not. For the MC test the subject will respond, "True," if the letters follow the rule stated on the card and False if it does not.)

3. Use the data sheet below to record the time and scores for each test.

4. To simulate microgravity, ask the subject lie down with their feet up on a chair for 10 minutes. (They may use a pillow under their head for more comfort.)

5. After the subject has been lying in the heads down position for 10 minutes, shuffle the flash cards and repeat the performance tests in the heads down position. Record the time and scores using the table below.
