“…Consistent with the findings of previous studies documenting neurobehavioral deficits during extended periods of wakefulness (Lamond & Dawson, 1999;Linde & Bergstrom, 1992), response speed and lapses remained at a relatively stable level during the period that coincided with the normal waking day (0-17 h) for both the PDA-PVT and the PVT 192. As hours of wakefulness increased, response speed significantly decreased and lapses significantly increased, with poorest performance on both tasks occurring after 47-49 h of wakefulness (0800-1000 h of Day 3).…”

In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-l92 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of wakefulness. Overall, standardized response speed scores on the 5-min PDA-PVT closely tracked those of the PVT-192; however, the PDA-PVT was generally apsociated with more lapses/minute. Closer inspection of the data indicated that when the level of sleep loss and fatigue became more severe (i.e., Day 3), the 5-min PDA-PVT was not quite as sensitive as the 10-min PVT-l92 when 2-to 10-sec foreperiods were used for both. It is likely, however, that the observed differences between the two devices was due to differences in task length. Thus, the findings provide further evidence of the validity of the 5-min PDA-PVT as a substitute for the 10-min PVT 192, particularly in circumstances in which a shorter test is required and/or the PVT-l92 is not as practical.

“…Significant effects have also been demonstrated on the Sternberg working memory task and were correlated with decreased fMRI activation in multiple brain areas, particularly the bilateral parietal cortices (Mu et al, 2005). Sleep deprivation effects on Raven's matrices (Linde and Bergstrom, 1992), verbal fluency (Horne, 1988), Tower of London (non-verbal planning) (Horne, 1988), Paced auditory serial addition test (Martin, 1996), and Trails B (Martin, 1996), have been reported. The effect of sleep fragmentation on cognitive abilities is generally less pronounced than the effects of sleep deprivation, despite similar effects on MSLT scores (Cote, 2003;Kingshott, 2000;Philip et al, 1994;Stepanski, 2002).…”

“…For example, Stroop performance change was affected by the pattern of sleep deprivation (Beaumont, 2001;Binks et al, 1999;Herscovitch et al, 1980). Variable effects on memory may be related to task difficulty (Cajochen, 1999;Harrison et al, 2000;Humphrey, 1994;Linde and Bergstrom, 1992;McCarthy and Waters, 1997;Smith, 2002). Significant effects have also been demonstrated on the Sternberg working memory task and were correlated with decreased fMRI activation in multiple brain areas, particularly the bilateral parietal cortices (Mu et al, 2005).…”

Vigilance is a term with varied definitions but the most common usage is sustained attention or tonic alertness. This usage of vigilance implies both the degree of arousal on the sleep-wake axis and the level of cognitive performance. There are many interacting neural and neurotransmitter systems that affect vigilance. Most studies of vigilance have relied on states where the sleep-wake state is altered, e.g. drowsiness, sleep-deprivation, and CNS-active drugs, but there are factors ranging from psychophysics to motivation that may impact vigilance. While EEG is the most commonly studied physiologic measure of vigilance, various measures of eye movement and of autonomic nervous system activity have also been used. This review paper discusses the underlying neural basis of vigilance and its assessment using physiologic tools. Since, assessment of vigilance requires assessment of cognitive function this aspect is also discussed.

“…Intermittent nausea, general fatigue, unintended distraction and sleep disruption are common features of a normal pregnancy that sometimes underlie human error. [15][16][17] Important physiologic changes related to pregnancy can occur before overt changes in anatomy are apparent. 18 Hence, the intermediate stages of pregnancy provide a potential interval of overconfidence when a person could be compromised yet still active.…”
