PREDICTIONS OF ARRIVAL SEQUENCES OF SIMULATED RADAR TARGETS AS A FUNCTION OF DISPLAY SIZE, TARGET SIZE, AND TARGET SHARPNESS

摘要

This experiment investigated the ability of observers to judge which of two aircraft, displayed on a simulated cathode ray tube, would arrive at a fixed reference line first. Aircraft trails were represented by five equally bright “blips.” The experimental variables were simulated display size, blip size, and blip sharpness. Four blip sizes for each of two display sizes were employed and blips were either sharply in focus or somewhat out of focus.
