Sleep Deprivation Hypothesis

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

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

One part of this article that I think is irrelevant is paragraph five. “Scientists have long puzzled over the purpose of sleep.” doesn’t relate to the topic of what genetic consequences sleep deprivation has. One thing I would clarify, is what changes were they looking for in the RNA (paragraph eleven). Another thing I would prefer to be explained is if being sleep deprived can make us have a petulant behavior and/or if it can affect the way we

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.

The students could rate their current mood on a scale from zero to seven. The higher the

In this article from LA Times “Sleep Deprivation Has Genetic Consequences, Study Finds” Eryn Brown asserts that a lack of sleep affects the function of genes related to stress and cell renewal, possibly contributing to poor health. Brown states that the more people who suffer from less sleep have a greater chance of having their emotions and actions react to their lack of sleep. Brown supports his claim by saying “researchers detected changes in the way hundreds of genes were expressed in their bodies”, another one is “lack of sleep translates into disease”, the last claim is “suggesting that tissue harm was occurring after sleep deprivation”. Brown addresses it in a tone eligible for the people who are reading this (adults and teens). “Using blood to assess the molecular effects of sleep deprivation”. Supposing that sleep deprivation is bad for your health, Brown reveals how sleep deprivation affects your health. For instance, “ people who work early in the morning or late at night- or who lack sleep in general- have higher rates of diabetes, stroke and high blood pressure, among other

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.

This study hypothesized that napping type (planned versus unintentional) would be a primary predictor of scores on cognitive assessments and self-rated memory. A secondary hypothesis of this study was that cognitive assessments would be significantly associated with napping frequency as well as napping type. These hypotheses were partially supported by the study findings. Planned napping was associated with higher scores on memory assessments, while frequent napping was independently associated with lower scores on one memory assessment. However, these results only partially remained after adjustment for highest level of educational attainment: while planned napping was still associated with higher scores on one memory assessment, napping

The formation of false memories is a highly-studied topic in several professional fields including psychology and law. Although it is such a heavily researched topic, there have been no substantial answers found as to what makes an individual more or less likely to form false memories. In this review, the findings surrounding the effects of stress level and mood on the likelihood to form false memories will be analyzed. For both variables, studies have not agreed on the impact they have on false memories. In fact, the findings of many studies discussed directly contrast each other. However, when scrutinizing the studies, it becomes evident that when participants experience more than their daily level of stress the likelihood to form false memories

The brain can be very susceptible to suggestions. Whether it is through hypnosis, therapy, or peers. Due to the ability for the brain to fall to suggestions, false memories can be an issue. False memories can occur though different means, such as a dream that seemed so real it was later thought to be an old memory, or it can even occur through suggestions by others. The fact that the brain can so easily be manipulated is important to be aware of; false accusations against others, by children especially, can lead to unjust prosecutions and destroy lives.

Allen. J, Elkin and D.J. Murray systematically lists the studies and opinions of others who agree with them and does not discuss opposing positions . In content first Allen. J, Elkin and D.J. Murray discuss that there has been many articles about sleep loss and how it effects vigilance (Deaton, Tobias, & Wilkinson, 1971), speed of addition (Williams & Lubin, 1967), and reaction time (Wilkinson, 1963) but there are hardly any articles about how sleep loss an effect memory. They follow that with their method, they had altogether 40 subjects 19 male and 21 females all who volunteered. 20 subjects were deprived of sleep for up to 55 hours and were compared with 20 subjects who had normal sleep over this period. The experiment took place in a room of the Department of Psychology. Everything was arranged for them. The experimental group they had a total of 55 hours of sleep deprivation. The digit probe technique (Waugh & Norman, 1965) was used to assess retention. The recognition was either immediate or delayed by 20 seconds. When it came to the results, it showed that the sleep deprived group had made more errors than

It is found that long-term sleep deprivation causes hallucinations, delusion and high cortisol levels that interferes with memory which results in

Sleep deprivation on the other hand can disrupt memory consolidation. Sleep deprivation is mostly common amongst us college students, and this could lead to having disagreements when it comes to friendships and love relationships, social relationships in general. Not having enough sleep could also lead to depression, it can make you gain unwanted weight
