MECHANISMS OF EYE AND HEAD MOVEMENTS IN DRIVING TASKS

A SERIES OF EXPERIMENTS DESIGNED TO INVESTIGATE A NUMBER OF CHARACTERISTICS OF EYE AND HEAD MOVEMENTS IN RESPONSE TO PERIPHERAL VISUAL STIMULI, AND THEIR RELATION TO THE TIME REQUIRED FOR THE OPERATOR TO MAKE A RESPONSE IS DISCUSSED. THE FIRST STUDY WAS PLANNED TO INVESTIGATE THE OVERSHOOTS AND UNDERSHOOTS OF THE EYE IN RESPONSE TO PERIPHERAL STIMULI OF FROM 5 TO 40 DEGREES. PROPORTIONATELY MORE UNDERSHOOTS OCCUR AS THE STIMULUS ANGLE INCREASES, BUT THE NUMBER OF OVERSHOOTS REMAINS CONSTANT OVER ALL STIMULUS ANGLES. FINDINGS WERE EXAMINED IN THE LIGHT OF SEVERAL THEORETICAL POSITIONS ON THE NATURE OF VARIABLE ERROR IN SIMPLE MOTOR RESPONSES. THE SECOND STUDY CONCERNED THE EFFECT OF RESTRICTING HEAD MOVEMENT OF SUBJECTS AND COMPARING THEIR RESPONSES TO PERIPHERAL VISUAL STIMULI WITH SUBJECTS WHO WERE NOT RESTRICTED. THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN THE RESTRICTED GROUPS AND THE NON-RESTRICTED GROUP IN TOTAL RESPONSE TIME. THE THIRD STUDY INVOLVED THE NATURE OF EYE AND HEAD MOVEMENTS DURING RESPONSES TO PERIPHERAL STIMULI. A NUMBER OF COMPARISONS WERE MADE. FINDINGS WERE EVALUATED WITH RESPECT TO RESEARCH IN THE AREA. /NSC/
