Abstract
The current study examined performance on an automated task battery under short-term sleep deprivation and non-sleep deprivation conditions. Twenty-six volunteers completed the sleep deprivation study. Twenty-three volunteers completed the non-sleep deprivation study. Performance was examined across five test sessions during 25 hours of acute sleep deprivation conditions and during two days of non-sleep deprivation conditions. ANOVAs examining changes in performance from baseline levels indicated that performance under sleep deprivation conditions resulted in a decrease in performance in some tasks and an increase in estimated blood alcohol concentration. Non-sleep deprivation resulted in stable or increasing performance and a decrease in estimated blood alcohol concentration. The Controlled Attention Model suggests that the task characteristics would have helped maintain performance levels but does not explain how performance decreased on some but not all of the tasks. Extending the Controlled Attention Model to include a broader self-regulation approach suggests that on some of the tasks the participants did not adequately regulate their engagement in the task (even with rapidly changing stimuli) resulting in a decrease in performance levels. Incorporating a self-regulation approach with the Controlled Attention Model could provide a model that better explains the range of effects seen under sleep deprivation conditions.
Highlights
The effect of good sleep habits on health and well-being is gaining attention in many societies, chronic sleep loss continues to be a common occurrence for many people
We examined the baseline data to insure that the participants in the two studies had similar performance levels at the start of each study
The current results indicate that performance on the subtasks of the Automated Performance Test Systems (APTS) decreased or remained stable under sleep deprivation and either remained stable or improved under non-sleep deprivation conditions
Summary
The effect of good sleep habits on health and well-being is gaining attention in many societies, chronic sleep loss continues to be a common occurrence for many people. The effects of sleep deprivation on the worker as well as the worker’s ability to perform are important issues in many work settings. The negative effects of shift work on sleep are well established (Åkerstedt, 2007; Pilcher, Lambert, & Huffcutt, 2000). Several reviews of the literature have concluded that sleep deprivation negatively affects performance on a wide range of tasks (Harrison & Horne, 2000; Lim & Dinges, 2010). There is a growing literature base that it is not always the simpler tasks that are more negatively affected by sleep deprivation. Complex language-based tasks can be more negatively affected by sleep deprivation than simpler language-based tasks (Pilcher, McClelland et al, 2007)
