Fatigue has been cited as a causal factor in industrial, medical and transportation accidents. A common theme in the accident analyses has been the lack of knowledge about fatigue effects. What types of tasks are most susceptible to fatigue? How are the effects manifested? To answer these questions this article reviews the basic research on fatigue effects on performance of laboratory tasks. Tasks were categorised as vigilance, cognitive or psychomotor. Fatigue (as induced by sleep loss) consistently degrades vigilance performance regardless of task. Decrements include increased reaction time and decreased accuracy. For cognitive tasks, however, some researchers have reported increased time and decreased accuracy associated with fatigue, but not on all tasks or not consistently. For example, categorisation tasks show both decrements and no effects. Similar inconsistency exists for math (decrements and no decrements) and logical reasoning. However, fatigue consistently degrades tracking performance either performed alone or in a battery of tasks. In summary the research supports that at least in some cases of fatigue, humans cannot 'see straight', cannot 'think straight', cannot 'do anything right', cannot 'seem to pay attention' and cannot 'lift a finger'.

“…Employees today must rely less on physical skills and more on their mental abilities as they encounter tasks that require them to monitor dials, video screens, and other displays for signs of malfunction or danger that demand rapid decision making and action. Activities requiring vigilant behavior include industrial quality control, robotic manufacturing, air traffic control, airport screening and inspection, nuclear power plant operations, long distance driving, transport operations, seaboard navigation, cytological screening, closed circuit television (CCTV) surveillance, and the monitoring of medical equipment in hospital settings (Beatty, Ahern, & Katz, 1977;Davies & Parasuraman, 1982;Mackie, 1977;Wiener, 1984). The maintenance of vigilant behavior is crucial not only for worker efficiency and safety but also for the security of the general public.…”

Vigilance: A Review of the Literature and Applications to Sentry Duty

Vigilance, or sustained attention, involves the ability to maintain focus and remain alert for prolonged periods of time. Problems associated with the ability to sustain attention were first identified in real-world combat situations during World War II, and they continue to abound and evolve as new and different types of situations requiring vigilance arise. This paper provides a review of the vigilance literature that describes the primary psychophysical, task, environmental, pharmacological, and individual factors that impact vigilance performance. The paper also describes how seminal findings from vigilance research apply specifically to the task of sentry duty. The strengths and weaknesses of a human sentry and options to integrate human and automated functions for vigilance tasks are discussed. Finally, techniques that may improve vigilance performance for sentry duty tasks are identified.

“…The available knowledge about the effects of sleep deprivation in clinical staff is derived from three main approaches. Psychomotor tests use standardised procedures for measuring the motor consequences of mental events or vice versa, for example card sorting, critical flicker fusion frequency and choice reaction time [10, 11]. The choice of test may be influenced more by ease of measurement and perceived sensitivity to fatigue than relevance to work‐related tasks and patient safety.…”
