Abstract
Two simple monitoring experiments were performed to study the dependence of probability of detection and of speed of response to detected signals on the initial probability of detection of the signal established psycho-physically and on duration of the task. The results indicated that: (1) detection during the task is directly related to the probability of signal detection before the task and inversely related to length of watch, and (2) the speed of response to those signals which are detected is directly dependent on the probability of detection before the watch but independent of factors which operate during the watch.Keywords
