PERFORMANCE DECREMENT IN VEHICLE DRIVING
ONE HUNDRED AND EIGHTY SUBJECTS WERE ALLOCATED TO FIVE GROUPS ON THE BASIS OF THE NUMBER OF HOURS THE MEMBERS OF EACH GROUP DROVE A TRUCK ON A FATIGUE COURSE AFTER AN INITIAL TEST, AND PRIOR TO A RE-TEST ON A BATTERY OF NINE DRIVING TESTS. THE FATIGUE PERIODS WERE OF 0, 1, 3, 7 OR 9 HOURS DURATION. AFTER DETERMINING THE INITIAL EQUIVALENCY OF THE GROUPS BY AN ANALYSIS OF PRE-TEST RESULTS, POST-FATIGUE TEST SCORES WERE CORRELATED WITH HOURS OF FATIGUE DRIVING. ALL 15 TEST SCORES YIELDED PART-CORRELATIONS SIGNIGICANT AT THE 5% LEVEL OF CONFIDENCE OR BETTER. CORRELATIONS REACHED A MAXIMUM OR R=.50. A DECREMENT FUNCTION WAS PRESENTED WHICH SHOWED PROGRESSIVE LOSS IN PERFORMANCE THROUGH SEVEN HOURS OF DRIVING. /SRIS/
