“…However, this is contrary to a number of vigilance studies that found a steady vigilance decrement for both novice personnel and experienced personnel (Baker, 1962;Mackworth, 1970;Pigeau et al, 1995;Schmidke, 1976). In these previous studies, both novices and experts were employed to perform the task used in the relevant study.…”

“…Closer examination of the studies with complex tasks referred to above, indicates that a number used student samples despite using tasks or simulations that were similar to those encountered in the real world (e.g. Hollenbeck et al, 1995;Molloy and Parasuraman, 1996;Pigeau et al, 1995). The current research found a distinct difference in the vigilance dynamics between participants (novices and generalists) with no or less experience, training, and exposure to the type of surveillance task performed in the study, and specialists with more experience, training, and exposure to this type of task.…”

“…Anecdotal evidence suggests that operator attention drifts after 15 min (Security Park, 2001), but this has not been examined in relation to detection performance and it is not clear whether this applies to all operators. Although there is the potential for vigilance decrements in work requiring vigilance, inconsistent results regarding the existence of vigilance decrements have been found in complex tasks (Adams et al, 1961) and tasks that are similar to those performed in real world settings (Hollenbeck et al, 1995;Molloy and Parasuraman, 1996;Moray and Haudegond, 1998;Pigeau et al, 1995). In view of variations in the information processing requirements of different vigilance intensive jobs and the numerous factors that affect vigilance performance, this is not surprising.…”

“…A vast body of research has shown that the effects of fatigue include decreased vigilance, adverse mood changes, perceptual and cognitive 2 decrements (Krueger, 1990;Belenky, Wesensten, Thorne, Thomas, Sing, Redmond, et al, 2003;Van Dongen, Maislin, Mullington, & Dinges, 2003), impaired judgment, and increased risk taking (Killgore, Balkin, & Wesensten, 2006), and even decreased marksmanship (Tharion, Shukitt-Hale, & Lieberman, 2003;McLellan, Kamimori, Bell, Smith, Johnson, & Belenky, 2005). Contrary to popular opinion in the military, research has shown that motivation can only partially compensate for the adverse effects of sleep deprivation (Pigeau, Angus, & O'Neil, 1995).…”

SUPPLEMENTARY NOTESThe views expressed in this thesis are those of the author and do not reflect the official policy or position of the Department of Defense or the U.S. Government. ABSTRACTThis study examined the effect of alterations in the timing of sleep within the circadian cycle on the amount of total nightly sleep and its influence on various indicators of mood and performance of U.S. Army Soldiers attending Basic Combat Training (BCT) at Fort Leonard Wood, Missouri. The quasi-experimental study design compared Soldiers assigned to one of two training companies: a company using the standard BCT sleep regimen (8:30 p.m. to 4:30 a.m.) or a company using a phase-delayed sleep regimen (11:00 p.m. to 7:00 a.m.), the latter being more in line with the biologically driven sleep-wake patterns of adolescents. Demographic and psychophysiological measures were collected at the start of the study using standard survey instruments and methods. A random sample of approximately 24% of Soldiers wore wrist activity monitors to unobtrusively record sleep quantity and quality. Weekly assessments were made of subjective fatigue and mood throughout BCT. Data on physical fitness, marksmanship, and attrition from BCT were extracted from organizational training records.The study sample was comprised of 392 Soldiers, 209 in the intervention group and 183 in the comparison group. Based on actigraphic data, it was shown that Soldiers on the modified sleep schedule obtained 33 more minutes of total sleep per night than those on the standard sleep schedule. Soldiers in the intervention group reported less total mood disturbance relative to baseline, but the effect size was modest and diminished over the course of BCT. Improvements in Soldier marksmanship performance over a series of record fires was positively correlated with average nightly sleep during the week preceding the record fires, when basic marksmanship tasks were being learned. By the end of BCT, Soldiers in the comparison group were 2.3 times more likely to have occupationally significant fatigue and were 5.5 times more likely to report poor sleep quality, as assessed using validated survey instruments, than those in the comparison group. There was no effect of the sleep scheduling intervention on physical fitness scores or the relative risk for attrition. Overall, increasing sleep and concomitantly decreasing fatigue had a small but measurable influence on var...

Of particular relevance to military training, the ability of individuals to learn and retain information is reduced by sleep deprivation (literature summarized in Miller et al, 2008).…”

Period of Research: 7/15/09 -9/30/09 1) Project Overview: Military training often includes some degree of sleep deprivation, either by design or unintentionally, which may have important implications for Soldier physical health, well-being, and performance. This study was conducted to determine if adjusting scheduled sleep periods to better complement age-specific biologically driven sleep patterns would improve sleep and performance in Army recruits completing basic combat training (BCT). A total of 394 recruits and instructor cadre were enrolled in the study: 185 participants in the control group (a training company using the standard sleep regimen) and 209 participants in the treatment group (a training company using an optimized sleep regimen designed based on a fatigue modeling tool). Demographic and psychophysiological measures were collected at the start of the study using standard survey instruments and methods. A random sample of 95 recruits wore wrist activity monitors to non-obtrusively record sleep quantity and quality throughout the study period. Weekly assessments were made of subjective fatigue and mood throughout the training period. Data on physical fitness, marksmanship performance, and attrition were collected from organizational databases. 2) Project Schedule:The original project schedule is shown below with schedule overruns highlighted in red. Schedule tasks 1-4 were accomplished as originally planned. A contract was awarded for data entry services starting 24Aug09 and expired at the end of FY09. Significant administrative delays were encountered in working the Defense Contract Management Agency (DCMA) to renew the data entry contract at the start of FY10. The contract re-award was not accomplished until 14Dec09. Consequently, data entry was not completed until 25Jan10. This caused a 78-day slip in the start of the data analysis task. In response, tasks 5 and 7 were divided into Phase I and Phase II efforts. The Phase I effort focused on that portion of the dataset that could be analyzed and reported prior to the 12Feb10 suspense. The Phase II effort will include analysis and reporting for the full dataset. 4) Overall Assessment of Project:The implementation phase of the study conducted at Fort Leonard Wood went well with excellent local support. Unfortunately, administrative delays related to contracting for data entry services significantly set back the data analysis phase. The limited Phase I analysis has identified promising preliminary results that will be explored during the Phase II analysis of the complete study dataset. 5) Way Ahead:The next step is to complete the Phase II data analysis and report writing. Determination of subsequent steps will need to await the Phase II findings.
