Available in PDF, EPUB and Kindle. Book excerpt: "This memorandum presents the results of experiments in which subjects were required to go without sleep for fifty hours. Because only three subjects could be tested at a time, the experiment was repeated three times. The experiment is regarded as a preliminary test of the hypothesis that observers would show signs of fatigue (decrement in efficiency of performance) when periodically tested in the performance of a psychologically complex task during a period of sleep- deprivation. Graphical representation of the performance of the nine observers tested indicates a decrement in efficiency. Efficiency in performance of complex psychological tasks suffered a significant decline during the course of 50 hours wakefulness."--Summary.

Available in PDF, EPUB and Kindle. Book excerpt: Clinical practice related to sleep problems and sleep disorders has been expanding rapidly in the last few years, but scientific research is not keeping pace. Sleep apnea, insomnia, and restless legs syndrome are three examples of very common disorders for which we have little biological information. This new book cuts across a variety of medical disciplines such as neurology, pulmonology, pediatrics, internal medicine, psychiatry, psychology, otolaryngology, and nursing, as well as other medical practices with an interest in the management of sleep pathology. This area of research is not limited to very young and old patientsâ€"sleep disorders reach across all ages and ethnicities. Sleep Disorders and Sleep Deprivation presents a structured analysis that explores the following: Improving awareness among the general public and health care professionals. Increasing investment in interdisciplinary somnology and sleep medicine research training and mentoring activities. Validating and developing new and existing technologies for diagnosis and treatment. This book will be of interest to those looking to learn more about the enormous public health burden of sleep disorders and sleep deprivation and the strikingly limited capacity of the health care enterprise to identify and treat the majority of individuals suffering from sleep problems.

Download or read book Sleep Loss and Complex Team Performance written by and published by . This book was released on 2008 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few objective assessments of the impact of sleep loss on team performance. The present study was designed to quantify the effects of fatigue on teams performing a complex task and to compare team data with individual data on a similar task. Participants were trained on a complex air battle management task (both in individual and team mode) for one week and then experienced a 36-hr period of sustained wakefulness. Forty-minute scenarios (individual and team) were iteratively completed throughout each experimental period alongside traditional cognitive performance tasks (e.g., simple math processing). Individual data showed the well-established performance reduction resulting from sleep loss and circadian variation at both the simple and complex task levels. Significant decrements were seen for both process measures (e.g., information gathering) and outcome measures (e.g., number of targets attacked) after sleep-loss on the complex task. In contrast, team scores on similar measures after sleep loss, did not degrade, and in some cases showed improvements relative to baseline (indicating a continuing team building process). Individual performance (both simple and complex) was significantly degraded during the early morning hours. Team data did not show the expected performance decrements.

Book excerpt: The effects of sleep loss on human task performance are discussed under total, partial, and selective deprivations of sleep. Some of the frequently used psychological tasks in studies of total sleep loss are described in sufficient detail so that experimenters could choose, on the basis of materials presented in this monograph, adequate tasks to fit their experimental objectives. Factors which play critical roles in determining the degree of task sensitivity to total sleep loss are listed. Effects of shortened hours of sleep on human task performance are discussed. Effects of selected sleep deprivation on performance are also commented upon. The commentary is followed by a bibliography on sleep deprivation with author and subject indices.
Download or read book Food Components to Enhance Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1994-02-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

Download or read book Sleep Needs Patterns and Difficulties of Adolescents written by Institute of Medicine and published by National Academies Press. This book was released on 2000-09-24 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sleep is not only a biological necessity but also a physiological drive. In today's fast-paced world, though, a good night's sleep is often the first thing to go. The effects of inadequate sleep are more than mere annoyances: they affect our mood and how we perform at school, work, and home and behind the wheel. Lost sleep also accumulates over time; the more "sleep debt" an individual incurs, the greater the negative consequences, according to researchers in the field. Research on adolescents and sleep has been under way for more than two decades, and there is growing evidence that adolescents are developmentally vulnerable to sleep difficulties. To discuss current research in this area and its implications in the policy, public, health, and educational arenas, the Forum on Adolescence of the Board on Children, Youth, and Families held a workshop, entitled Sleep Needs, Patterns, and Difficulties of Adolescents, on September 22, 1999.
Download or read book Commercial Motor Vehicle Driver Fatigue Long Term Health and Highway Safety written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-09-12 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.

Download or read book Resident Duty Hours written by Institute of Medicine and published by National Academies Press. This book was released on 2009-04-27 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical residents in hospitals are often required to be on duty for long hours. In 2003 the organization overseeing graduate medical education adopted common program requirements to restrict resident workweeks, including limits to an average of 80 hours over 4 weeks and the longest consecutive period of work to 30 hours in order to protect patients and residents from unsafe conditions resulting from excessive fatigue. Resident Duty Hours provides a timely examination of how those requirements were implemented and their impact on safety, education, and the training institutions. An in-depth review of the evidence on sleep and human performance indicated a need to increase opportunities for sleep during residency training to prevent acute and chronic sleep deprivation and minimize the risk of fatigue-related errors. In addition to recommending opportunities for on-duty sleep during long duty periods and breaks for sleep of appropriate lengths between work periods, the committee also recommends enhancements of supervision, appropriate workload, and changes in the work environment to improve conditions for safety and learning. All residents, medical educators, those involved with academic training institutions, specialty societies, professional groups, and consumer/patient safety organizations will find this book useful to advocate for an improved culture of safety.

Download or read book The Dynamics of Recovery on Different Performance Parameters Following Sleep Deprivation written by Rochayne L. Kahl and published by . This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whilst a substantial amount of research has demonstrated the negative impact of sleep deprivation on human performance, studies looking at recovery of performance following sleep deprivation are limited. The current study examined recovery of performance following two nights deprivation where recovery opportunity was restricted to 6 hours each night over five nights. Following sleep deprivation it was hypothesised that (a) performance would not recover to baseline levels, and (b) different performance tasks would vary in how they recovered. Eleven healthy subjects aged 19 to 24 years were recruited and remained in the laboratory for nine consecutive nights: an adaptation and baseline night with 9 hours time in bed (TIB) from 2300 to 0800; two nights of sleep deprivation (SD) culminating in 66 hours of sustained wakefulness (SW); followed by five nights recovery sleep with 6 hours TIB from 0200 to 0800. During the experimental period subjects were tested on performance tasks every two hours for approximately 30 minutes. These included the Psychomotor Vigilance Task (PVT), measuring sustained attention, and three other tasks including Stroop, measuring cognitive interference; Serial Addition, measuring mental arithmetic and Six Letter Search, measuring working memory. Across the recovery period PVT performance remained impaired, stabilising at lower than baseline levels and failing to recover. In contrast, recovery of the other tasks occurred by the second recovery day. The PVT is highly sensitive to the effects of sleep loss, and is considered to be a basic indicator of sleepiness. Therefore, results indicate that even after five restricted recovery sleep opportunities subjects were still sleepy, albeit at stabilised levels. For the remaining more complex tasks, results may indicate a functional recovery with limited sleep. However, learning effects may have influenced the results on these tasks. Overall, results suggest that more complex tasks may recover more quickly from the effects of sleep loss.

Download or read book Sleep Loss and Workload Cognitive Effects and Physiology written by Kimberly Ann Honn and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation aims to investigate some of the complex interactions between sleep loss, workload, cognition, and physiology. In order to examine the effects of workload on fatigue (operationally defined as a state of reduced alertness) and performance, commercial airline pilots flew two duty schedules in a high-fidelity, moving-base simulator. The duty schedules were of equal duty duration and start time, but had differing levels of workload related to the number of flight segments flown. The higher workload condition, with more flight segments, had higher levels of fatigue, as shown through subjective measurements and through impairment in vigilant attention.
