Predicting Human Performance III: Detection of a Simple Visual Signal as a Function of Time of Watch
Abstract
The percentage of detection of 37 studies of vigilance, using simple signals, were found to depend primarily on the initial or pre-test detection level, the nature of the signal, i.e. whether it is a dynamic signal (requires movement or change of state of the eye) or static, and the duration of the watch. The loss of detection associated with static signals was assumed to be more representative of a loss in a 'vigilance' or attentional process. That loss appears to be rapid in development, essentially complete in about 35 min., and small in amount. The greater decrements associated with dynamic stimuli were assumed to be due to an additional process of eye fatigue.
