Five sets of data are presented, obtained from studies that examined the influence of time of day on auditory vigilance performance during the normal waking day. Although both hits and false alarms exhibited a fairly consistent tendency to be lowest at the first test time in the morning, 1 or 2 hours after awakening from sleep, and to increase in parallel thereafter, the magnitude of change was modest and the lime-of-day effect was statistically reliable in only a minority of the analyses. The slight changes that did occur seemed largely attributable to shifts in response criterion rather than to altered levels of signal detectability. In admonitory contrast with these findings, which have reassuring implications for vigilance efficiency during normal day-work, additional evidence is presented indicating that detectability levels may aller within the daylight span when the normal sleep-work-rest routine is disturbed.
