The video by Russell Foster about sleeping was interesting and informative. One of the facts given in the video was really impressive; an average human sleeps about 36% of the time in their life. For example, if a person lives 90 years then, he or she sleeps 32 years of their life. This is really fascinating that an average human would sleep over one-quarter of their lifetime. Secondly, I was amazed when I heard the fact that “100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep.”…
Sleep is very important process that is necessary for restoring strength after a hard day and resting the nervous system. However, different groups of people require different doses of sleep depending on their age. Another factor that has a serious impact on the quality of the sleep is a sleep schedule, which also depends on the age. For example, adolescents have different natural times to sleep than kids and adults. Indeed, following the appropriate schedule of sleep may have a strong impact on the result of the daily routine of a student.…
Humans tend to sleep 5-8 hours every night, and to do so in a pattern tied to the 24-hour light-darkness cycle. This cycle is called a circadian rhythm which means ‘about a day’. It is a naturally occurring body rhythm that occurs in a 24-hour cycle. Sleep is not the only cycle that is considered to be circadian however.…

The argument of “Rethinking Sleep”, by Davis K. Randall, is people should consider sleeping in segments rather than 8 hour blocks. The two reasons are, naps with deep sleep help brains function at a high level, and segmented sleep improves daytime performance. Two more important pieces of evidence for the first reason are , “...recent studies suggest that any deep sleep- whether in an eight-hour block or a 36-minute nap- primes our brains to function at a higher level, letting us come up with better ideas, find solutions to puzzles more quickly, identify patterns faster, and call information more accurately. ”(lines 51-54), and “ Researchers at the City University of New York found that short naps helped subjects identify more literal and…
I have chosen to watch the video by Russell Foster: Why do we sleep? Russell Foster says that “If you're an average sort of person, 36 percent of your life will be spent asleep”. That sounds like a lot to me, but I know that sleep in a necessary part of life. Although scientists don’t have a definitive answer as to why we sleep, they do have some theories.…
These three studies, plus countless more, strongly show that sleep is vital to our functioning and survival as human beings, and the seemingly unconnected failures that can occur with even an hour less of sleep per…
Quiet eye is a gaze behavior first reported by Joan Vickers of Calgary University in 1996. The Quiet eye has been defined as the duration of the final fixation towards the relevant target prior to the execution of the critical phase of movement and has been accepted as a measure of optimal visual attentional control. The quiet eye has an onset that occurs before the final movement in the motor task and an onset that occurs when the fixation deviates off the target by more than 3 degrees for more than visual angle of more than 100ms (Vickers, 1996, p. 348). Vickers has found that longer quiet eye durations characterize greater expertise and accuracy.…

Homework chap 3 lifespan Chap 3 Assignment Questions 1. Explain how sleep patterns are characterized over the course of life: infancy, childhood, adolescence/emerging adulthood and adulthood/aging (briefly for each of the 4 stages When we consider the sleep patterns during infancy, we have learned that newborns need approximately 16 to 17 hours a day but, some sleep more than others. Newborns sleep is sporadic: so the need to eat and to change diaper might modify the sleep pattern. Although, the range is from a low of about 10 hours or to high 21 hours per day.…
When people sleep, their body rests and restores its energy levels. A good night sleep means to help you cope with stress, solve problems, or recover from illness. “Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement sleep, which consists of Stages 1 through 4. During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep.”…
Sleep can be defined as a necessary time of physical and mental rest, where consciousness, thought, and voluntary movements stop and sporadic dreaming occurs. No one knows why or how humans and other animals sleep, but it is certain that the type of sleep affects quality, quantity, and effectiveness of wakeful mental and physical activities. However, scientists have confirmed that sleep occurs in two stages, REM and NREM. REM sleep is rapid eye movement sleep and NREM is non-rapid eye movement sleep. These activities then affect the quality, quantity, and effectiveness of sleep (Thompson 1).…
The definition of sleep from the Merriam-Webster dictionary is: the natural periodic suspension of consciousness during which the powers of the body are restored. Sleep is a wonderful, yet mysterious, thing. It can be identified as one of the most peaceful parts of your day.
