EFFECTS OF SUSTAINED PERFORMANCE ON DIFFERENTIAL ANGULAR VELOCITY JUDGMENTS

THE EFFECTS OF SUSTAINED PERFORMANCE ON SUBJECTS ABILITY TO MAKE DIFFERENTIAL ANGULAR VELOCITY JUDGMENTS WAS STUDIED IN THE LABORATORY. THE DEVICE USED CONSISTED OF TWO BELTS, ONE ABOVE THE OTHER, MOVING RIGHT TO LEFT. TEN DIFFERENT BELT SPEED RATIOS WERE USED. THE SUBJECT JUDGED WHETHER THE TWO BELTS WERE MOVING AT THE SAME OR DIFFERENT SPEEDS. IN THREE HOUR SESSIONS, 20 SUBJECTS MADE 27 JUDGMENTS FOR EACH OF THE TEN SPEED RATIOS. NEITHER RESPONSE SPEED NOR ACCURACY OF JUDGMENT WERE RELATED TO DURATION IN THE SESSION. HOWEVER, THERE WAS A STRONG INTERACTION BETWEEN SUBJECTS AND TIME FOR BOTH RESPONSE SPEED AND ACCURACY.
