Many of us don't give much thought to what happens when we don't sleep well or completely miss an entire night's sleep. Often we ignore this and plan to catch up on missed sleep over the weekend. We don't consider the long-term consequences of this choice and don't realize how bad sleep deprivation has. However, research indicates that lack of sleep has several effects on the mind and body. So, the question is: does lack of sleep affect memory? The answer is yes, it does. Sleep deprivation affects our memory and our ability to clearly recall declarative memories. Sleep deprivation can affect several types of memory, including our semantic memory, emotional working memory, and procedural memory. So, before you think about organizing another all-night study session, consider these facts first. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get the original essay The Role of Sleep in Memory When we sleep at night, our brains do many important things while we are unconscious. Sleep is vital for storing memories. When we are awake, our brain spends much of its time encoding the information it receives from our various senses. When we sleep, our brain begins to consolidate information from the day and store it in our memories. “Recent research highlights the importance of slow-wave sleep for memory consolidation. » This suggests that deep sleep is necessary for consolidation, because slow-wave sleep only occurs in stages 3 and 4 of the sleep cycle. “Consolidation arises from the reactivation of recently encoded neural memory representations, which occur during slow-wave sleep and transform representational memories to integrate them into long-term memory.” Deep sleep is essential for retaining new memories and ensuring they are stored permanently. If you don't reach the deepest stages of sleep, there's a good chance that the information your brain received throughout the day won't be consolidated effectively or stored for long-term memory. Effects on semantic memory A very important aspect of memory which is Sleep deprivation affects our semantic memory, especially it is very detrimental to adolescents. Adolescents' semantic memory can be affected by lack of sleep. The study is aimed at adolescents because they do not chronically benefit from the recommended daily sleep duration of eight hours. In the study conducted by the Center for Cognitive Neuroscience, they tested whether adolescents' abilities to retain information were affected by lack of sleep. Their study involved a control group allowed to sleep nine hours a night and a group restricted to five hours for five nights to test the effects. After the fourth night of sleep restriction, the sleep-deprived and control groups were instructed to learn about different types of arthropods over a six-hour period. They were then tested thirty minutes after learning the information, then again three days later. The results of this study indicated asignificant deficit in retention capacity in the sleep deprived group. This study mentions that our understanding of the effects of sleep deprivation on memory is still very limited. More research is needed to understand how much our declarative memories are affected by insufficient sleep. This study illustrates the need to emphasize the importance of sleep health, not only for adolescents but also for adults. This study is one of three studies that examined the effects of sleep restriction over more than one night. It is possible that prolonged sleep deprivation can be extremely detrimental to semantic memory over a long period of time. Effects on Emotional Working Memory An interesting aspect of our memories that is affected by sleep deprivation includes our memory emotional work. When a person doesn't get enough sleep, they are often more irritable than they usually would be and may have difficulty completing simple tasks. “There is neural evidence that supports an increase in emotional reactivity and a decrease in cognitive control of emotional responses toward positive reactions and negative stimuli. The study conducted by Schwarz was interesting because it examined a little-studied effect of sleep deprivation, emotional working memory. The study included a well-rested control group and a group of sleep-deprived individuals who underwent the N-back test on different images after assessing their emotional and sleepiness states. The results indicated that those who were sleep deprived lacked accuracy in their working memory on the N-back test. Overall, the results suggest that sleep deprivation has a detrimental effect on our working memory as well as our emotional control. The study admits that a possible limitation is that the sleep control group was not monitored, which could have affected the accuracy of the results. Effects on Procedural Memory When we don't get enough sleep, it has a negative effect on our cognitive abilities the next day. day. You may have more difficulty completing daily tasks or be more prone to making mistakes. Procedural memory is responsible for your ability to walk, talk, and perform basic motor functions. This lack of sleep causes our attentional processes to operate at less than optimal capacity, making these tasks more taxing. Chronic sleep deprivation impairs memory's ability to perform tasks accurately. (Roger Ratcliff, 2018). Not only does lack of sleep affect our memory, but it also affects our ability to complete our daily tasks. Michigan State University conducted a study to find out how sleep deprivation affects procedural memory. In the study, a control group slept normally at home and an experimental group stayed awake at night for twenty-four hours. They were then given a specific task that required following a sequence in order to correctly complete the task. Once again, results indicated that sleep deprivation negatively impacted the subject's ability to accurately perform the sequential task. “For some participants, lack of sleep caused a loss of ability, or even willingness, to perform the task as instructed, which they had successfully done the previous evening.” This demonstrates how twenty-four hours of sleep deprivation can have an effect on our basic abilities to function. Imagine, if you suffer from chronic lack of sleep, how difficult daily tasks..
