Sleep Research
The purpose of this study was to investigate the influence of mood on subjects' perceptions of the adequacy of their sleep, their reports of overall satisfaction / dissatisfaction with life, and the accuracy of the estimations task performance... It was hypothesized that sleep attainment influences the ability accurately judge adequacy of their sleep, cognitive functioning, and perceptions of satisfaction with their lives. The findings suggest that a lack of sleep may result in depressed affect which may cast a negative valence on self-reports. The research suggests additional inquiry into relationship between sleep attainment, mood at the time of report and prior to the report, and other aspects of life, such as job satisfaction, interpersonal relationships, economic status, and general health.

Participants. The sample consisted of 150 first-year...
All of the subjects were fluent in English. Seventy-one percent of the sample was female and twenty-nine percent was male. Of the 106 female subjects, the mean age was 22.27 years and the standard deviation was .61. The mean age of the 44 males in the sample was 23.18 years and the standard deviation was .90.
Instrumentation (measurement). When reporting the amount of sleep they attained, students were asked to estimate how many hours, on average, they slept on a typical night. To measure subjects' perceptions of their satisfaction with life, The Satisfaction with Life Scale (SWLS) (Diener, Emmons, Larsen, & Griffin, 1985) was used. The scale contains five items to which the subjects were asked to reply as honestly as they could, indicating their agreement or disagreement with the statement by using a 7 point scale.…
Introduction The purpose of this study was two-fold: 1) it aimed to identify relationships between sleep and other aspects of human functioning/performance; and 2) it sought to understand how sleep-wake patterns impact daytime functioning. The subject of this research was the researcher himself. The researcher kept a 4 week sleep diary with which to record information pertaining to sleep habits and daily life habits in order to test the conclusions of
Sleep Behavior and Habits Scientists have known for decades that the human sleep and wakefulness are controlled by complex factors that influence the circadian rhythm that regulate sleep in all mammalians and in most other forms of so-called higher biological life. More recently, physiologists have identified very important direct connections between sleep cycles, and sleep deprivation in particular, and human health. Specifically, sleep deprivation and the disruption of regular sleep-wake
(Harvard School of Public Health, 2013, p.1) Energy expenditure is decreased due to sleep deprivation because there is a decrease in physical activity as well as the body temperature being lowered. (Harvard School of Public Health, 2013, p.1) Summary of Literature The literature reviewed in this study has informed the study that children who sleep less hours each night are at a higher risk of becoming obese than children who sleep more
Sleep deprivation is frequently a direct result of the need for intensive care, constant surveillance and monitoring that combine to limit the opportunities for uninterrupted sleep in the intensive care unit (ICU). The problem is multifactorial, with patients' chronic underlying illness, pain, pharmacological interventions used for the treatment of the primary illness, as well as the ICU environment itself have all been shown to be contributing factors to the process
Infant Sleep Patterns People sleep nearly one third of their lives and infants sleep significantly more than adults (Franken, Kopp, Landolt, & Luthi, 2009). The function of sleep has hypothesized by different researchers; however, surprisingly there is no general consensus as to what the function and purpose of sleep actually is. It is known that sleep deprivation can have some serious consequences, especially in infants. The reason for this is that
Dreams, Why Do We Have Them and What Do They Mean Origins and Significance The main causes of dream have been assigned to two major thoughts-natural and supernatural. The natural cause has further been categorized as psychological and physiological. Allan Hobson and Robert McCarley have in 1970, during the sleep period called Rapid Eye Movement suggested that the visual as well as emotional brain parts get into action. Any other sensation, whether physiological
