A study was conducted on the effects of 72 hours of sleep loss and modified continuous operations on performance and psychological variables. This paper presents the results of self-report data of 12 subjects for the following psychological variables: sleepiness, affect, motivation, cognitive difficulties, and waking dreams. The relationship between the self-report measures and performance in a visual search and memory task is also examined. Most of the psychological variables are significantly affected by the number of days of sleep deprivation, all are significantly affected by hour of day; but only sleepiness, affect and motivation are also significantly affected by the interaction between these variables. The peak hours for self-reported psychological complaints are generally between 0400 and 0800, while the lowest number of complaints are usually reported in the afternoon/early evening, between 1600 and 2000. In addition, the results showed that (a) the amplitude of the circadian component of the psychological data increased over the period of sleep loss, and (b) psychological data were more highly correlated with a measure of general performance than with accuracy. The mechanisms of sleep deprivation underlying its effects on psychological and performance measures are discussed.

“…Low workload may permit high levels of initial performance because of short-term high energy expenditure (Alluisi & Chiles, 1967), which may not be available when subjects are under continuous, high workload conditions. Therefore, shorter duration tasks may be more sensitive when workload conditions are more severe.…”

Studies attempting to estimate the degree of performance degradation resulting from sleep loss typically use relatively long-duration tasks that are distinctly separate from ongoing activities. Since long-duration tasks are not practical for assessing the performance degradation induced by sleep loss in field settings, this study was designed to examine whether the results of shortduration (I-min) tasks were markedly different from those of long-duration (lO-min) tasks with respect to detecting performance changes during a 54-h period of sleep loss and sustained cognitive work. Performance changes also were examined as a function of the location of tasks within work sessions by comparing performance on I-min tasks that were placed within work sessions with those tasks that immediately followed short rest periods. The results showed that shortand long-duration tasks were equally sensitive to sleep loss. In addition, once sleep-deprivation effects began to emerge, it was found that performance on short-duration tasks within work sessions showed significantly more impairment than performance on tasks that followed rest breaks. These results suggest that task duration is not a critical factor for detecting performance degradation induced during continuous work experiments but that the location of tasks within work sessions is critical for accurately assessing expected performance.
