A BATTERY OF 29 RELIABLE, VALID, AND REPEATABLE COGNITIVE AND PSYCHOMOTOR PAPER-AND-PENCIL TESTS, EACH PURPORTING TO MEASURE A SPECIFIC CONSTRUCT, WILL BE USED TO ASSESS PERFORMANCE OF 48 OLDER MALES AND FEMALES IN THREE SEPARATE AGE GROUPS (55-60, 65-70, 75-80 YEARS). A GROUP OF 16 MEN AND WOMEN AGED 25 TO 35 WILL SERVE AS THE CONTROL. THIS BATTERY WILL BE DIVIDED INTO THREE SUB-BATTERIES; THEY WILL BE GIVEN ON THREE SEPARATE WEEKS. EACH TEST OF A BASIC ABILITY WILL BE ANALYZED SEPARATELY ACROSS A TOTAL OF FIVE DAYS AND FIFTEEN TRIALS, WITH THREE TRIALS BEING GIVEN EACH DAY. TEST TIME FOR EACH SUB-BATTERY BY TRIAL WILL BE APPROXIMATELY 33 MINUTES. THE POTENTIAL FOR TECHNOLOGICAL INNOVATION LIES WITH EACH TEST HAVING 15 ALTERNATIVE FORMS THAT CAN BE USED TO DETERMINE PROBLEM-SOLVING STRATEGIES, LEARNING CURVES, AND STABLE PERFORMANCE SCORES WITHIN AND BETWEEN SUBJECTS OF THESE SIX AGE/SEX GROUPS ACROSS A SPECTRUM OF 23 COGNITIVE AND FOUR PSYCHOMOTOR BASIC ABILITIES. IN ADDITION, THESE SCORES CAN BE FACTOR ANALYZEDTO DETERMINE A VALID STRUCTURE OF PERFORMANCE THAT WOULD ALLOW FOR THE DEVELOPMENT OF A BATTERY OF TESTS ORIENTED TO OLDER SAMPLES OF THE POPULATION.
