The extent and eminence of sleep has a profound impact on learning and memory. A sleep deprived person cannot focus attention optimally and cannot learn efficiently. “Sleep is a biological phenomenon that is modulated by the plasma concentration of melatonin and with influence on behavioral aspects and memory” ( Donadon 2016). All through life sleep plays a biological part in memory. Sleep has a role in the alliance of memory which is essential for learning new information. As some may know, many college students do not get adequate sleep but what effect does this have on their way of learning?
Without sufficient sleep and rest overworked neurons can no longer function to synchronize information properly, and humans lose their aptitude to

They are trying to get a perspective on how sleep effects a person’s memory and learning capability. Researchers will find out if an increase in sleep will improve the function of memory and learning. Referring to the hypothesis, this will be a positive correlation since memory and learning will improve as sleep improves. This will be a between subjects design because this study consists of four groups that is being tested by different factors which would be designated sleeping times in this …show more content…
Group A will receive two hours of sleep, Group B will receive four hours of sleep, Group C will receive six hours of sleep, and Group D will receive six hours of sleep. Each group will be held in a separate room according to their designated sleep schedule and be held in ideal sleeping conditions such as quiet dark room with bed , blankets and other sleeping material.
Before participants sleep, researchers will administer the Karolinska Sleepiness Scale which will measure an individual’s drowsiness. The ratings would measure from 0 (tremendously alert) to 9 (tremendously sleepy). This assessment is used to assess the extent to which concurrent sleepiness affected the task. The participants will then sleep in the designated areas during their designated time. This assessment will also be measuring the predictor variable which will be the amount of sleep a participant receives and how they feel after the
All mammals exhibit Rapid-Eye-Movement, or REM, sleep, and yet on certain levels this type of sleep would seem to be disadvantageous. During REM sleep, which is when most dreams occur, the brain uses much more energy than during non-REM (NREM) sleep. (1) This "waste" of energy coupled with the increased vulnerability of this state on account of the body's paralysis at this time suggests that there must be a very important reason, or reasons, for the existence of REM sleep and in extension of dreams. Determining the function of dreams, however, has proved very problematic with many arguments which directly oppose each other. Some of the primary functions of dreaming have been tied to is role in development, its production of neuro-proteins, and also to how it may allow for the "rehearsal" of neurons and neuronal pathways. The influence of dreaming on learning is one of the hottest debates. Some argue that dreams aid in learning, others that dreams aid in forgetting, and yet others that dreams have no effect on learning or memory. That REM sleep seems to aid in development might argue that REM sleep may be connected to learning. It seems that most scientists believe that REM sleep aids in certain memory consolidations although some argue that it actually leads to "reverse learning.
(Vecsey, 2009; Thomas et. al. 2000). Lack of sleep also affects our level of cognitive performance and
Sleep deprivation is a commonplace occurrence in modern culture. Every day there seems to be twice as much work and half as much time to complete it in. This results in either extended periods of wakefulness or a decrease in sleep over an extended period of time. While some people may like to believe that they can train their bodies to not require as much sleep as they once did this belief is false (1). Sleep is needed to regenerate certain parts of the body, especially the brain, so that it may continue to function optimally. After periods of extended wakefulness or reduced sleep neurons may begin to malfunction, visibly effecting a person's behavior. Some organs, such as muscles, are able to regenerate even when a person is not sleeping so long as they are resting. This could involve lying awake but relaxed within a quite environment. Even though cognitive functions might not seem necessary in this scenario the brain, especially the cerebral cortex, is not able to rest but rather remains semi-alert in a state of "quiet readiness" (2). Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex while other stages of sleep seem to be used for forming new memories and generating new synaptic connections. The effects of sleep deprivation on behavior have been tested with relation to the presence of activity in different sections of the cerebral cortex.
Is sleep important for memory consolidation? Past research has found that sleep is an important factor in the consolidation of newly acquired memories; however, this consolidation often depends on the specific memory as well as when (e.g., time after learning) sleep occurs. It is important to note that sleep is not constant, throughout the night. Sleep is a cycle that is broken down into rapid eye movement (REM) and non-rapid eye movement (non-REM) sleep (Stickgold, 2005). Non-REM consists of sleep stages 1 through 4, in which stages 3 and 4 constitute what is known as slow-wave sleep (SWS) (Rasch & Born, 2008). Moreover, the construct of memory is often divided into different types of memories, declarative (e.g., facts and events) and non-declarative (e.g., procedural skills) (Stickgold, 2005). When discussing memory consolidation, research has defined it as a progression of memory stabilization that leads memories to become resistant to interference (Stickgold, 2005). Results from past research indicate that memory consolidation occurs through the reactivation of memories during sleep, which enhances and stabilizes the memory (Diekelmann & Born, 2010).
This article is from The Journal of Experimental Psychology, and was written on an experiment performed by psychologist Bruce R. Ekstrand, from the University of Colorado. He experimented on the effects that sleep has on one's memory, after learning a particular bit of knowledge, in this case a certain list of twelve three-letter words.
Sleep is one of our basic needs to survive and to function in day to day operations, but not everyone needs the same amount of sleep. Some people can survive on very little sleep, i.e. five hours a night, and some people need a lot of sleep, to the extend that they are sleeping up to 10 to sometimes 15 hours a night (Nature, 2005). According to Wilson (2005) the general rule states that most people need from seven to eight hours of sleep. The deprivation of sleep in our society in continually increasing with the demands in society increasing work loads, the myth that a few hours of sleep is only necessary to function properly and that sleep is sometimes considered as killing time (Nature, 2005). Sometimes sleep deprivation is also caused by other situations like sleep disorders, i.e. sleep apnea, chronic insomnia or medical conditions such as stress (Wilson, 2005).
The brain is the most important organ in the body and without it life would not exist. In a metaphorical sense, the brain can be thought of as a master computer. Functions of the brain include physical behavior, emotion, learning capability and memory. Since the beginning of scientific exploration, the brain has been a significant area of interest and its complexity still puzzles scientists today. New research methods and advances in technology have allowed humans to understand more about the brain within the past 10 years than in the preceding centuries (Brain Basics, 2013.) Research on the role of sleep in brain functionality shows surprising promise. The amount and quality of sleep an individual receives effects learning ability and the risk of developing brain diseases such as Alzheimer’s.
(Man/Woman): Hey everyone, I’m going to talk about something that most American colleges have: “Fraternities and Sororities”. “Fraternities and Sororities” are groups of students that usually live together in a house. Members are usually called “brothers” or “sisters”. These social groups often throw parties. They also host events where they raise money to help people. “Fraternities and Sororities” are a huge part of American college culture. (65 words)
The researchers tested their hypotheses in two methods. In the first method the researchers selected 78 individuals. 65 of the individuals were women. The participants chosen were on average 21 years of age. The participants also had been in a romantic relationship for 20 months. The participants were asked to keep a paper sleep diary in which they would write in every day and night for 2 weeks. The participants were then told to transfer the information to an online diary and asked to answer a few questions about their experience. The information the participants needed to keep track of was kept short. The information noted were things like: how long it took for the participant to sleep, how many times the participant woke up, how long they slept, the quality of sleep, and how tired they felt that day. Each category was scored using a 5 point number scale. The lower the score the better.
Sleep is important to the brain, because it is believed that when we sleep it restores brain chemicals and provides rest to the body.
Another academic benefit associated with a good night’s sleep is the ability to better retain
Research shows that sleep is a necessity in order for someone to be able to perform at their maximum potential. College students are no exception to the rule and are often at a greater risk to suffer from conditions that accompany sleep deprivation. Regardless of the time period, a college student must be well rested in order to perform at his or her best in terms of physical performance, memorization capabilities, and test-taking abilities. Also, without adequate sleep, the person will be more susceptible to illnesses, both mental and physical. In conclusion, I believe that sleep deprivation among college students is extremely common and has a direct effect on how well that student will perform or feel.
Sleep is an integral part of life, but differs from other states of reduced consciousness in that the brain is still somewhat active. Sleep is an “altered state of consciousness, [with the sleeper losing] substantial contact with the external world.” (Gazzaniga, M., & Heatherton, T., 2016). Nonetheless, brain activity has an extensive role in the creation of “sleep”, generating two distinct types - slow-wave sleep, also referred to as deep sleep, and rapid eye movement, also called the dreaming stage. Comprised of five stages, sleep is a complex state of mind, also consisting of patterns known as circadian rhythms. Operating as a behavior, sleep alters to suit our bodily needs, and informs us of such needs through an intricate network of nerves. Furthermore, without obtaining an ideal amount of sleep, problems can arise that may affect one’s wellbeing. Detailed research and studies previously conducted on the subject of sleep allows the accumulation of information to be
Important public policy issues have arisen in our modern 24-hour society, where it is crucial to weigh the value of sleep versus wakefulness. Scientific knowledge about sleep is currently insufficient to resolve the political and academic debates raging about how much and when people should sleep. These issues affect almost everybody, from the shift worker to the international traveler, from the physician to the policy maker, from the anthropologist to the student preparing for an exam.
Sleep plays a vital role in a person’s mental well-being. Sleeping affects how well people think, react, work, learn, and get along with others. While a person is sleeping, his brain is preparing to help him learn and remember information. A good night’s sleep enhances learning and problem solving skills. It is very important for the students to have sound sleep as it can improve their concentration, memory and creativity. Furthermore, having enough sleep increases the ability to m...
