Ever wonder why you can’t remember things you should or why you are having trouble concentrating? You probably did not get enough sleep. Having more than six hours of sleep is known to help you think clearly and aid in learning and memory consolidation. In some cases, it is impossible to get enough sleep with the 24/7 society we live in. As a result, researchers have shown that by merely believing you have slept more, you are likely to increase your performance on mental tasks. In the study, 50 participants were asked to comment on how well they had slept the night before. The participants were told that most adults spend 20-25% of their sleep in rapid eye movement (REM) – deep sleep associated with dreaming. They were also told that those who spend more than 25% in REM sleep perform better on learning and memory tests compared to those who spend less than 20% of their sleep in REM. The participants were then hooked up to a machine to measure heart rate, pulse, and brain wave frequency to indicate the percentage of REM sleep they had the night before. But in actuality, the researchers only measured their brain wave frequency. They then randomly assigned participants to one of two groups: the “above average” sleep group or the “below …show more content…
By giving the participants only one test, we don't know if we can generalize the results to other types of questions testing mental performance. Also, because the participants knew that those with higher REM sleep perform better than those with lower REM sleep, they could've acted in a way to meet this criterion. Another limitation was that the experimenter was aware of what assigned group the participants were in. This awareness could lead the experimenter into only recording data that agreed with their hypothesis. In an attempt to address these concerns, the researchers conducted another
Methods: The participants, all males age 23-32, slept in a dark, quiet lab while their brain waves and eye movements were recorded. They were not aloud to sleep at all during the day when they were not in the lab because they might dream. To establish a base for the experiment, participants in the study were allowed to sleep normally for a few nights. The next few nights the participants were fully awaken every time that they started to dream. The next section was the recovery phase where they could sleep normally followed by more nights where they would be woken between
43 % of public high schools start before 8 a.m. Studies show that kids in school need 8.5-9.5 hours of sleep each night. Studies also show that 2/3 of kids in school get less than 7 hours of sleep each night. Because of all of these facts, 33% of high school students fall asleep in class. School should start later than 8 because kids still in school need more sleep than the 6-7 hours they get.
This article explains the importance of getting the perfect amount of sleep at night. The idea that sleeping for less than five hours or more than nine hours proves to have a negative effect on the human body. Sleep deprivation has a closely related link to memory retention and can cause a person to have trouble with daily task. The author continues to explain that not only is the brain effected by too little or too much sleep, but the rest of the body is also effected. Conditions such as high blood pressure, diabetes, and even depression have links to not getting the perfect amount of sleep. The article concludes with listing tips to get the ideal amount of sleep at night, such as, going to sleep and waking up at the same time every day and limiting the amount of caffeine that is consumed throughout the day.
How many of you would rather be asleep right now? I am assuming that mostly everyone sitting here would say yes, including myself. I wake every weekday morning at 6:30 and personally see all the proven negative effects of teens waking up at an hour they aren’t mean to. Sleep patterns throughout teenage years are to go to sleep late then wake up late. While for adults and children, it is the exact opposite. Elementary schools start at 8:45 while most of those kids do not need that exact hour of sleep. That extra hour of sleep given to high school students could make a world of a difference.
I am in favor of pushing Oregon City High School’s start time to 8:30 and ending later. Many teens who are involved in sports or have another after school activity are always complaining that they are so tired in the mornings. Even as I look around now, I see at least 4 students who are sleeping or are the edge of falling asleep with heavy eyelids— myself included. Even trying to catch the bus at 6:30 a.m in the morning is hard. In the winter, the sun doesn’t even crest the horizon till 7 a.m. It takes a toll on lots of high school students getting up before 6 o’clock just to get ready and be at the bus stop on time. Just reaching over to press the snooze button is as much energy as I can muster up prior to the sun coming up!
Did you know that approximately 87% of high school students get less than the recommended 9 hours of sleep every night? The majority of high schools students are not getting enough sleep each night because they have to wake up very early each morning for school. Many are sleep deprived, have trouble functioning during the day, and often do poorly on tests and quizzes. This problem could easily be solved if high schools pushed back start times to after 830am.
Now I am late for school again, I wish it started later… well, it really should not, yes it would lower the amount of tardiness but is it worth it? No some reasons are because it would be hard and for some expensive to handle the switch, Kids need to realize that this is how it is going to be for the rest of your life, and lastly After school tutoring programs and such would be so much more confusing, complicated, and tiring.
When students hot high school, they experience something new. Students have a wake up at such an early time to make it at school on time. My high school started at 7:30 am, and I had to get up at 6am to take a shower, get dressed, and have breakfast just to get to school on time. When first period hit, I am still so tired. Also, take in account the kids who have to take the bus to get to school on time. Those students have to get up so much earlier than most to catch their bus. Students should not have to be so tired during class. High school students should be allowed to sleep in and come to school at a later time do they aren't so tired and they can focus better Students just aren't getting enough sleep.
The article Sleep deprivation and false memories reported two studies, but only study one will be summarized here. The study done here is to see if amount of sleep is associated to false memories. This study is a correlational study because it is looking for the association of natural occurring variables (i.e. the amount of sleep one gets). The independent variable of this study is the amount of sleep the participants had, either they were sleep deprived or not. The dependent variable is whether or not they had false memories. The participants were made up of one hundred ninety-three undergraduates from the University of California, Irvine, 76% of which were female and 24% were male. The participants were divided into two different groups based on their self-reported sleep duration only on the night prior to the study session. The participants who reported five or fewer hours of sleep were put in the restricted sleep group, those with more than five hours were put into the reference group. Neither group differed meaningfully on age, gender, race-ethnicity etc.
Perelman School of Medicine at the University of Pennsylvania was trying to find out how the amount of sleep affects your body mentally. This is important so we know how to take care of ourselves and stay healthy. To test this experiment, the Perelman School of Medicine got a group of 40 adults and put them into two different experimental groups. They were placed in either a group where they stayed up for 28 hours consecutively or in a group where they received a full 8 hours of sleep. Afterwards, all participants took a computer based test. The students studied how the participants reacted to happy, neutral, or sad faces through accuracy and response time. Overall, the studies showed that the participants who stay up for 28 consecutive hours
How many times has this happened to you; it’s six thirty on a Tuesday morning, your alarm has already gone off twice, your still laying in bed and your bus comes in twenty minutes. This is an everyday occurrence at my house. It is a proven statistic that the average high school student does not get enough sleep. While some experts like Dr. Lee Yanku say “It is not the schools starting time that is the problem as to why students don’t get enough sleep, it is because of facebook, myspace and cell phones” The truth behind it is that we can’t budget sports, homework and extracurricular activities into one day and still get nine hours of sleep. This is hurting student’s academic averages and needs to change. Changing the school time will help
In addition, a recent study, published by Matthew Walker and his colleagues at the Sleep and Neuroimaging Lab at UC Berkeley, proposed a link between dreaming and emotions. These scientists focused on individuals during REM, rapid eye movement, sleep. REM sleep is one of the many stages the body experiences during sleep, which also stimulates the regions of the brain used for learning. In addition, individuals do the most dreaming during REM sleep. They found that a reduction in REM sleep negatively influences their ability to comprehend and work through complex emotions in day to day life (Scientific
Sleep is essential for optimal human function. In fact, a lack of sleep can actually affect important cognitive functions, like memory. A 2007 study added to the already substantial evidence that even acute total sleep deprivation impairs attentiveness, working memory, and reaction time in various tasks (Alhola, Polo-Kantola). One such way to further this investigation of the effects of sleep deprivation on memory is through the Memory Interference Test, or MIT. MIT is a program designed by Gaston Pfluegl, Ph.D., and Enrique Lopez, Psy. D., at UCLA to test the memory of students. Along with a memory test, the MIT also anonymously collected the physical states, mental states, and demographics of each student test subject, providing a substantial database through which students can test hypotheses, such as the connection between sleep deprivation and memory. Since the MIT requires short-term memory recall, the hours of sleep a student had before taking the test could have a noticeable effect on his or her performance. An unprecedented study this year found that sleep deprivation may actually even induce false memories, which would certainly impact a student taking the MIT because the test requires the subject to recognize images that have been previously presented to them (Frenda, et al). The hypothesis is that students who slept 8 hours before the test will perform better on the MIT than students who only slept 4 hours. The null hypothesis is that students who had adequate
There have been many experiments performed trying to find the correlation between sleep and memory. One of these experiments has showed that different stages of sleep has different effects on memory for instance, not only has sleep been seen to combine new memory with old long-term memories, but also helps stabilize memory (Born & Rasch, 2013). Using the Memory Interference Test (MIT), Amir conducted an experiment to further confirm the conclusion that the sleep improves a person’s memory. The experiment compared the amount of correctly remembered pictures by a sample people who had eight hours of sleep compared to a sample with only four hours of sleep. The hypothesis is that there is a correlation between the amount of sleep a person
We will use a simple questionnaire that was used in the Emmons and Mcullough (2003) study to operationalize the sleep variable. The questionnaire will ask participants three questions. The first question will be a close-ended question that asks participants to rate the quality of sleep they received the previous night on a scale of 1 (restless) to 5 (restful). The second question will be open-ended, asking participants to indicate the hours of sleep they had the previous night. Hours of sleep will be calculated as the total hours in bed minus time spent awake. Our last question will be an optional and open-ended question that will ask participants if they
