Researches on the Measurement of Human Performance.
Abstract
In 1943 the Royal Air Force asked for laboratory studies that might determine the optimum length of time radio operators in antisubmarine patrols should be kept at watch. This request was made because of evidence that during patrols numbers of potential U-boat contacts were being missed. This report records visual and auditory vigilance tests, in which the conditions under which men actually operated during watch to detect signals indicating presence of enemy underwater craft were...
