By the age of 6 months a circadian rhythm is established and by the age of 1 year infants are usually sleeping mainly at night, with 1 or 2 naps during the day. The periods of deep sleep lengthen and there is a reduction in the amounts of active/REM sleep. Sleep patterns change during childhood and by the age of 5, children have EEG patterns that look like those of an adult but they are still sleeping more (around 12 hours a day) and having more REM activity (about 30% of total sleep time). Boys are also found to sleep slightly more than girls. As childhood progresses, the need for sleep decreases, but in adolescence it increases slightly, to around 9 or 10 hours a night.
English 111 2/6/13 Summary According to “Americas Sleep-Deprived teens” we aren’t getting enough sleep and in some instances to much sleep. Many teens are falling asleep in class and not getting there work done. Weather it’s the parents not knowing, everyday pressures or other factors the fact is children aren’t getting enough sleep. The National Sleep Foundation (NSF) conducted a survey and the findings were pretty interesting. While many parents claim that they know there children’s sleeping patterns and make sure they get enough sleep, more than one half (56%) of adolescents say they get less sleep than recommended.
However stuffing information into your brain takes time, which is taken up by being in school and other activities. By staying up late studying, we compensate for those lost hours and get a leg up on the students who didn’t stay up. Or so we think… In a study done by Pilcher and Walters, 44 college students were placed into either a sleep deprived, or non-sleep deprived group and allowed to sleep and wake up at certain time during the three-day experiment. After the three days were up, each group took a series of tests and questionnaires. When asked how they thought they did, the sleep deprived group reported to have had a higher level of concentration and an increased level of effort.
When you were a teenager, how often did you find yourself sleepy during school? How often did you fall asleep during class? Research probes that if schools had later start times kids would be more alert during the day, grades would improve, behavior would improve, and there will be less tardiness. Lets face it, most teenagers usually go to bed late, meaning they wake up late for school, and then result in tardiness. Constantly being for the same class, students begin to fail, and who wouldn't be upset from that?
Stage 3 and 4 also known as slow wave sleep (SWS) is characterised by delta brain waves, during these stages most of the body’s repair work is undertaken. In REM sleep there is fast, desynchronised EEG resembling the awake brain and the body is paralysed (cataplexy). Dement and Kleitman’s (1957) carried out a lab study with 9 participants and showed that when patients were woken during REM sleep they were far more likely to report dreaming. As the night progresses SWS gets shorter and REM sleep longer. Dement and Kleitman can be criticised for their very small sample size as it is unlikely to represent the range of individual differences in sleeping and dreaming.

Running head: Module D Test Module D Test Jason Robertson PSYCHOLOGY 1101 – Module D Test Dr. Ewing 2/10/13 Module D Test Sleepwalking is probably the most common sleep disorders. Sleepwalking is most commonly seen in children, although it can be seen in adults and the elderly. Boys are more likely to be sleepwalkers than girls are, and the disorder usually runs its course before the teen years. The rates of the occurrences can vary from person to person, some may only sleep walk once a month, while others may sleep walk nightly. I have never experienced sleep walking or know anyone who has so it’s hard for me to understand it.
And, in an article by the National Sleep Foundation, their statistics show that the average 12th grader has about four different electronics in their room, which makes causes distraction and delays falling asleep. pg 523 According to a recent poll, sleep experts recommend 9 or more hours for adolescents but only 20% of children (ages 11-17) the recommended amount and most parents are unaware of their child’s sleep deprivation. And, just as sleep deprivation affects an adults capacity to function properly and make sound decisions, lack of sleep causes adolescents to fall asleep in class, arrive late to school, and feel down and
They specifically looked at the dependence symptoms, driving after drinking, and productivity losses broken down by male/female and officer/enlisted ranks. This study showed that although men reported more binge drinking, women demonstrated the same or higher levels of alcohol dependency and were more likely to cause a loss of productivity in their work. Women also were at a higher risk of developing alcohol related problems than men. They concluded that the military needs to do a better job conducting preventative treatment when service members return from combat and recommended that physical and psychological health reassessments are given to service members within three to six months upon returning state side to help identify those members that may at-risk or who need to seek immediate
