Cognitive Perspective Sleep Deprivation

Sleep is a rather peculiar action. Why does the brain and the body basically need to lose connection to the world for a few hours? Insomnia, which is the inability to sleep, can cause many symptoms and they are not delightful whatsoever. Sleep deprivation is not only rough because of obvious reasons, but the consequences that harm the brain and body can be devastating. Even if people know what sort of symptoms are, they do not know why these things happen.

Humanistic theories of motivation suggest that people have cognitive reasons to perform various actions. Individuals are motivated

Sleep deprivation is prevalent in industrialized societies and has been linked to serious health issues and traffic accidents. This essay views sleep and sleep deprivation from five different motivational perspectives in order to gain a holistic understanding of the phenomena. From evolutionary, psychodynamic, behaviourist, cognitive, and hierarchy of needs perspectives, it is inferred that the cognitive and behaviourist perspectives uphold the most merit for gaining understanding into sleep and sleep deprivation. However, it is

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.

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.

Cognitive perspective focuses more on memory, intelligence, problem solving, and language, which has become a major factor in psychology. Cognitive perspective also focuses on the field of cognitive neuroscience, which studies the physical works of the brain and nervous system when dealing with memory and thinking. In order to witness the structure activity of the brain, neuroscientist use machines such as, magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET).

Cognitive perspectives are mainly about the mind. The reason being is because they are trying to see what is going on in the human mind. Cognitive also is trying to see how us as human process information in our mind. Psychology that study cognitive perspectives is mainly studying the “mental act or process by which knowledge is acquired.” They are just

The effects of partial sleep deprivation on cognitive performances (such as attention and reaction time) was examined in twelve handball goalkeepers. After becoming familiar with the tests, the subjects participated in three tests in a randomized order over three days with a 72 hour rest period in between each session. These three days were (i) a reference-night which subjects slept nine hours, (ii) a partial sleep deprivation at the beginning of the night (SDB) where subjects slept from 3:00 to 7:00 a.m., and (iii) a partial sleep deprivation at the end of the night (SDE) where subjects slept from 10:00 p.m. until 3:00 a.m. During each session subjects performed a reaction time test, a selective attention task, and a constant attention task. In order to ensure there was no learning effects during the reaction test, barrage test, and Stroop test, the form and color were changed between sessions. Results show that the biggest effect was towards reaction time, which increased significantly from the reference night to SDB (p < 0.001) and SDE (p < 0.001). Also the results showed that reaction time was significantly higher during SDE than during SDB. Selective attention and constant attention decreased significantly from the reference-night to SDB and to SDE. Likewise, selective attention was significantly lower during SDB when compared to SDE. These findings suggest that cognitive performance (reactive time, selective attention, and constant attention) of handball goalkeepers

Cognitive perspective is an overview on how the mind perceives and process different areas. These studies consist of learning, remembering, planning, solving, judging, deciding, and speaking. The study is performed to gather information on

What do the effects of sleep deprivation have on people? When a person does not get enough sleep, he or she is depriving his or her body of something that it needs. A delightful sleep is one of the most satisfying human experiences with a role to play in supporting a good mood and cognitive acuity as well as in promoting physiologic balance and resilience (Chittora, Jain and Suhalka). People think because they get an insufficient number of hours of sleep, they will not have an emotional impact by it. Sleep is a required need for peoples’ day to day life to be able to perform and stay healthy emotionally and physically. The effects of sleep deprivation are an issue because it affects mood, performance, and health.

Advantages of sleep come from many different theories of sleep. Although we don’t know exactly what the purpose of sleep is, several theories show the positive side of the purpose of sleep. The first theory is preservation and protection. This does not directly impact Tamara’s studying, but it is based off of an evolutionary adaptation that causes us to sleep to stay out of harm’s way. Growth theory deals with the release of growth hormones at night. Body restoration deals with the body repairing itself after the day such as the brain tissue repairing itself during sleep. This could directly impact Tamara’s studying as her body needs the rest in order to repair itself from the information it took in that day. The theory of memory is a giant

The expectancy theory of motivation clarifies the behavioural handle of why people select one behavioural alternative over the other. This explanation specifies that there is a definite relationship between efforts and performance, the outcome of a high execution will result in a desirable reward, a reward from an achievement will satisfy a significant need, and/or the result fulfils that they require sufficient to make the exertion beneficial.
