Maintaining the level of vigilance by means of artificial signals

Abstract

In improving the performance of radar operators, what is the influence of the person watching him? 2 conditions having 25 Ss each were established. In both Ss wore head-phones. There were real and artificial signals. The experimental group only was given knowledge of results by a voice over the head-phones. Differences in results were compared by half-hour periods of time. Increase of signal frequency was also a variable. The increase in signal frequency and knowledge of results both improved performance of radar operators.
