“…Studies have shown that, on tests of cognitive performance, response latency increases as a function of cumulative sleep deprivation (Weiskotten and Ferguson, 1930;WiUcinson, 1961;Corcoran, 1964;Naitoh, 1968;Naitoh and Townsend, 1970;Hamilton et al, 1972;Kjellberg, 1977;Tilley et al, 1982;Babkoff et al, 1985; Monk and Folkard, 1985;Patrick and Gilbert, 1986). When humans are sleep deprived, mean response latency is thought to increase because of significantly longer response times (several times normal) on some trials, while the majority of performance trials are completed within normal response intervals.…”

“…The performance similarities before and after napping may be accounted for by both after-nap sleep inertia (Naitoh & Townsend, 1970) and circadian influences (Folkard & Monk, 1980) combined with fatigue. Sleep inertia can last for 1-2 h or more (Taub, 1979;Wilkinson & Stretton, 1971).…”

The effects of physical work (30% of VO, max), sleep loss (3-h nap during a 48-h operation), continuous work (CW), and time of day on cognitive performance were assessed (by ANOVA) in this repeated-measures study comparing two groups (exercise/nonexercise) of healthy young men (N = 22). Treadmill walking did not accentuate or attenuate sleep-loss effects on performance; however, sleep loss alone did degrade visual vigilance and memory for words. Time-of-day fluctuations were found in choice reaction time, logical reasoning, and word memory. Visual vigilance for nonexercising subjects degraded sooner on the 2nd CW day than it did for exercising subjects. A 3-h nap at 0400 h after 1 17-h CW day was not immediately recuperative. These findings indicate that exercise at 30% ervo, max does not compound sleep-loss effects in cognitive performance. Indeed, physical activity during video terminal monitoring may delay any sleep-loss decrement. Variability of many cognitive abilities throughout the day appeared to show a greater ef-. feet than the sleep-loss and exercise effects over 2 days.A modern high-technology society requires full-time, round-the-clock services. The usual response to this requirement has taken the form of various shift systems, staffed typically by two or three stationary or rotated crews ("shifts"). However, some occupations require extended periods of continuous work (CW) on a regular or periodic basis. Examples include fire fighters, police, health care providers, rail and air transportation workers, and nuclear, petrochemical, and steel workers. Some of the most dramatic examples of CW are in military engagements. Military planners recognize that, should engagements be necessary, the weakest link may well be human, not hardware (Radomski & Defayolle, 1981).The major endogenous factors delimiting optimum, extended human performance have been identified as health, physical fitness, fatigue, training/skill level, information processing ability, and biological rhythms. External factors are work load, work-rest cycles, and environmental hazards (Englund, 1979;Englund, Naitoh, Ryman, & Hodgdon, 1983). Resolution of problems arising from the influence of these factors is the subject of intensive investigation. Intervention methods for performance enhancement range from pharmacology (exter- . Discovery of the means/mechanisms to support sustained quality mental and physical performance is the major objective of most CW studies that involve critical industrial or military applications. The relationships between physical work, sleep loss, and mental efficiency are not fully understood and require study, if we are to optimize performance under CW conditions. The present study is concerned with mental effectiveness during repeated CW periods. Successive sustained operations are those in which partial or complete rest/recovery periods separate two or more intensive, extended, work phases. Specifically, we have been studying the effects of continuous and repeated work episodes on cognitive performance, by m...

“…Nearly 20 years of this research has produced a vast array of data describing the effects of such variables. Although a summary of these findings is beyond the scope of the current discussion, the reader is referred to the several summaries, reviews, and bibliographies that are available in this area (see Alluisi, 1967, Alluisi & Morgan, 1982, Home, 1978, Krueger & Fagg, 1981, Naitoh & Townsend, 1970, Thompson, 1983, Webb, 1982, and Woodward & Nelson, 1974.…”
