Sleep Dependent Memory And Its Effect On Children

Memory can also be affected by lack of sleep. Also peoples inability to remember things can be affected.

This paper examines five different sources of information that addresses information pertaining to wakeful resting or sleeping and the effects it has on memory garnered by experiments performed on humans and animals. Wakeful resting is defined as an individual that has not fallen asleep but has engaged in a period of rest that cuts them off from the distractions of the outside world. Sleep is the bodies natural cycle of rest that suspends the consciousness and allows both the body and the mind to take a break from any stressful activities and recover. By either taking a short wakeful rest or going to sleep after learning new material, memory consolidation in both humans and animals will be improved, and it is not limited to humans that

There are a few factors that are essential for life such as breathing or eating, but one of the most essential factor is sleep. Even though the amount of sleep people need differs from one individual to another, the fact is that eventually everyone needs to sleep. People know the importance of sleep, but due to the increased workload and the pressure of society people are getting less sleep. As a result, there has been an increase interest on the effects lack of sleep has on the mind especially the memory of a person. Many questions arose about the relationship between sleep and memory due to the fact most high school and college students have become sleep deprived. For example, does more sleep mean higher grades?

In the article Teachers,Students and Sleep, author Dave Stuart address the effects of different qualities of sleep have on students. Stuart covers the causes for poor sleep and the consequences this can have. The author repeatedly references the work of Harvard graduate Maria Konnikova, along with Shawn Stevenson who has a bachelor's degree, thus they appear to be reliable sources. Stuart cover the negative effects of artificial light close to sleep, and the many positive effects of regularity in other activities on the sleep cycle. Dave Stuart makes his readers reevaluate how important sleep is.

An article in Nature Neuroscience from February 2009 describes an experiment which was conducted regarding sleep and its correlation to memory. Memory was impaired after 35 hours of sleep deprivation weekly and constant shallow sleep. Regular sleep benefits memory as newly stored information is easily encoded. Proper sleep is crucial for processing and retaining new information. Those who suffer from sleep deprivation struggle to maintain new information and with comprehension skills. In order for students to maximize their learning capabilities, they need the proper sleep to be mentally prepared for

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.

Most studies are about discovering the contributors of false memories. However, this study focuses on how sleep deprivation contributes to false memories even though many studies argue that sleep deprivation damages cognitive function. Their study went in detail by researching the effect encoding have during this process. They found that if a participant was sleep deprived during event encoding; he or she would increase the likelihood of falsifying memories. However, when the participant was sleep deprived after encoding had already occurred then there was no big impact on falsifying memories. These experiments are conducted on the effect of sleep deprivation contributing to false memories since false memories can have dreadful consequences.

A greater understanding of these complex and dynamic brain states has helped clarify the ways in which sleep enhances memory processing. An increasing number of sleep studies have behaviourally assessed the facilitative role of REM and NREM sleep on declarative and procedural memory performance in humans. The preliminary results provided initial evidence to the idea that hippocampal-dependent declarative memories, such as memories of personal events and fact-based information, are facilitated by NREM sleep (specifically SWS) and hippocampal-independent procedural memories are facilitated by REM sleep (Plihal & Born, 1997).

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

Frenda, Patihis, Loftus, Lewis and Fenn’s (2014) article titled “Sleep Deprivation and False Memories sought out to explanation how sleep deprivation can have a role in an individual’s cognitive function. One-way researchers went about unraveling this particular question was to uncover the invisible knowledge relating the formation of false memories with sleep deprivation. Two experiments were executed diving into the many ways that sleep deprivation can affect a person’s thoughts and general decisions, using many examples.

Therefore, the rapidly developing cognitive functions of infants necessitate even more rapid and consistent sleep cycles to foster their learning. Sleep plays a role in the memory consolidation process when the baby is awake. It has not yet been determined if infants can learn while asleep (Tarullo, Balsam & Fifer, 2011).

“The specific loss of REM (rapid eye movement) phase sleep also results in memory loss (Poriel

The impact of sleep behavior on memory recall is a new topic in psychology study field, but the result of this research will help many researches in the future. Sleep not only brings people physiologically relax but also improve people’s ability on memory recall. 300 undergraduate students in UW participated in an experiment about memory recall test (recall a list of words). The text result and later analysis showed that, after sleeping, students tend to gain higher score in their memory recall test. Students who take a nap(sleep group) before take the memory test have an average 4.5 points higher than students who do not(non-sleep group). The relationship between sleep and memory recall is significant, and p-value is also smaller than 0.01.

They also determined that sleep helps with memory. The brain registers and stores an infinite amount of information every day. This information flows through the hippocampus (the structure in the limbic system that has a special role in the storage of memories). When a person sleeps, the hippocampus keeps the important information and “throws out” the information not needed. The brain creates vivid dreams which are just exaggerated versions of the information that was not stored. With the brain free of useless information, associations can be made that were not seen

Many Studies have been conducted dealing with sleep and memory. Research results prove time and time again that sleep plays a role in memory and how we retain information. Bunney and Potkin suggest that declarative memory is improved by sleep (Bunney and Potkin, 2012), while Benson and Feinberg suggest that memory is retained more after Full-relaxed sleep (Benson and Feinberg, 1975). This paper will examine Bunney and potkin’s research findings and Benson and Feinberg’s research findings to prove that sleep does in-fact effect memory.
