Abstract:

THE RELATIONSHIP OF PULSED AND CONTINUOUS LIGHTING UPON A COMPENSATORY TASK, AND ITS SUBSEQUENT EFFECT ON SCOTOPIC DETECTION PERFORMANCE WAS EXAMINED UNDER TWO LEVELS OF ILLUMINATION. RESPONSE LATENCY OF DETECTING LANDOLT RINGS AS WELL AS THE NUMBER OF DETECTION ERRORS INCURRED WAS AN INDEX OF THE TIME REQUIRED TO EFFECTIVELY REGAIN DARK ADAPTATION. ON THE BASIS OF THE RESULTS OBTAINED, IT IS CONCLUDED THAT DARK ADAPTATION MAY BE PRESERVED IF THE VISUAL DISPLAY TO WHICH AN INDIVIDUAL IS ATTENDING IS ILLUMINATED WITH PULSED LIGHTING IN THE FREQUENCY RANGE OF 5 TO 15 CPS. IN THIS CONDITION, THE EXPERIMENTAL VEHICULAR TRACKING PERFORMANCE APPEARS UNIMPAIRED
