Sleep Deprivation And False Memory Summary

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

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as

Thesis: Sleep deprivation can lead to serious health problems, make you forget information, and have a negative impact on the outlook of life.

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

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

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.

As a college student, the information David Randall presents is very intriguing due to the fact that most of us are sleep deprived due to late night studying, among other things. It is very evident that Randall relies on statistics to build and progress his argument. He tells us how over time certain statistics have increases and by how much. This opens our eyes and makes us realize that there really is an issue. By providing these sources Randall becomes trustworthy and our doubt of whether this is true or not are put to rest. The author comes into contact with our feels once he brings in true stories to the picture. He informs us of the incidents that have occurred due to sleep deprivation. At this point the issue becomes more than a statistical

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

With the concerning matter of sleep peralisys some have turned to the belief that hypnosis is to be a trustworthy factor. On the contuary hynossis is not a trustworthy mean of displaying accurate memories because hypnosis can often create false memories. Consciousness also plays a large rule in our subjective experience of ourselves and the every cahgning world. On average we spend nearly thirty percent of our waking hours, mind wandering, and fantasizing. INitally we spend as much as one third or more of our lives in one specific state of consciousness in the sense of sleep. Thus sleep plays a critical role in storing memories and remembering emortional information. Over the years we have learned that sleep is critical for the function of our immune system, planning, reasoning, and functioning to the best of our

While much research has been conducted regarding sleep deprivation Tatar J, et al. 2006 demonstrates the results of sleep

To find out how sleep deprivation affects humans, Dement (1960) connected participants of his study to an electroencephalogram in his sleep laboratory. The participant got woken up any time they showed signs of entering REM sleep. I was found that REM sleep deprivation made test participants more aggressive and suffered from poor concentration than the control group. They also tried to enter REM sleep straight after going to sleep. They made 26 attempts to enter REM sleep by the seventh night. It is to conclude that REM sleep is necessary for proper brain functioning as the brain goes into REM rebound, when deprived of
