The Effects of Noise and of Loss of Sleep Upon the Observation of 3 Sources of Signals with Unequal Probabilities,
Abstract
Three groups of 12 naval ratings had to monitor 3 sources of signals, and to report each time they detected a signal. A source was checked by pressing the corresponding key and looking for a dull red flash. One group worked with and without noise. The other group worked after a night without sleep and after normal sleep. Noise has a beneficial effect in making the man concentrate more on the most probable source of signals. But noise has a detrimental effect in increasing the number of misses in the second half of the experimental period. Whereas loss of a night's sleep has only detrimental effects. It stops the man from concentrating more on the most probable source of signals. And it makes him require more evidence before he reports a signal.
