Declarative Memory

Great Essays
Consolidation of memory; the process of maintaining information in your LTM is strongly influenced by the role of sleep (Potkin and Bunney, 2012). “Declarative memory or explicit memory, emphasizes the representation and organization of factual knowledge (Reed, 2013).” Declarative memory plays a key role in an adolescent’s school performance and the process of consecutive social functioning. This study explores the effect of normal sleep on auditory declarative memory in adolescents ages 10-14. A hypotheses of this study being; if performance on the control working memory task involves encoding and memoranda manipulation, then control of working memory will not be affected by time, day or relationship to sleep, rather declarative memory is …show more content…
“In this study, subjects were trained on a paired- associate declarative memory task and a control working memory task at 9:00 a.m., and tested at night (12 hours later) without sleep (Potkin and Bunney, 2012).” “The same number of subjects were trained at 9:00 p.m. and tested at 900 a.m. following sleep (Potkin and Bunney, 2012).” Rapid Eye Movement (REM) sleep is defined as unplanned action of the eyes, vivid dreams, and minimal muscle tone all over the body (Mastin, 2013). Lack of REM sleep strongly affects your ability to recall visual location and produces a decline in slow- wave sleep, deep sleep, which strongly affects your declarative memory consolidation ability. Slow- wave sleep is high in adolescents before puberty, but decreases by 60% between the ages of 10 and 20 (Potkin and Bunney, 2012). This is relative because a key reason in psychiatric and developmental disorders in adolescents is most adolescents do not get the proper amount of sleep, often sleep is disrupted (Potkin and Bunney, …show more content…
Removal of the outliers was present, leaving the study with nineteen sleep subjects and eighteen no sleep subjects. Lavene’s test was used to show there was equality between all of the variances and comparisons (Potkin and Bunney, 21012).The group assigned to sleep task had a number correct of 6.58 during initial testing for the Letter- number control task and the number correct for the no-sleep group was 6.06 (t = (1.54), df (1.35), p = 0.13) (Potking and Bunney, 2012). During the second round of administration, it was found that the letter- number correct was 6.26 and 6.33 (t = (-.16), df (1,35), p = .088). Neither of the groups showed an important statistical difference for the letter- number task for the first and second administration (paired t test, p = 0.32 for sleep group and .45 for no- sleep group. “ An increase of 20.6 % in long- term memory was found as measured by the number correct in paired- associate test following sleep, compared to the group which was tested at the same time interval, but without sleep (p<0.009, with a 32.7 % increase ( Potkin and Bunney,

    Students report getting less sleep than they need from about the age of 13 years” ( Onyper et al). A very large portion of students need to wake up at 6:30 to be at school on time, which means in order to get enough sleep, the teen would have to be asleep by 9 p.m. As a result of the circadian clock in teenagers’ brains, it’s almost not possible for adolescents to be asleep that early. The U.S. Secretary of Education, Arne Duncan, even thinks that schools should adopt later start times (Blad). With all of this evidence that schools start too early there are still very few schools that begin the school day after 8:30 a.m. “Forty-two states reported that 75%-100% of their public schools had…

    I never took any naps that day. My overall sleepiness/alert today is 1 out of 7. I was quite tired when I awoke at 6:00am, but as the day went on I became more alert. I went to sleep at a decent hour, but waking up at 6:00 AM, only gave me 7 hours and 30 minutes of sleep. Even though I slept well without any disturbances, I still had a hard time functioning; I never got to my full alertness until noon.…

    However, that also found that once one’s sleep lasted for over 9 hours that there was in fact a reverse effect and students performed worse than they had when sleeping for 8.5 hours (2016). These numbers are stated in multiple studies and that is addressed as this study helps to solidify the credibility of other similar studies conducted. The 3 authors came to the conclusion that it was within a nation’s best interest to allow teenagers to sleep 8.5 hours per night, with individual flexibility, and that while the economic changes that later school start times might impose need to be researched,…

    There is one way in which we could have smarter, and better feeling students. One factor that is causing sleep deprivation is the early school start times. Says that childrens brains are not funcitioning properly before 8:30 A.M. Studies show that eighty percent of middle and high schools are starting to early. Waking up at the crack of dawn isn't fun for any body not the teens that have to get up or the parents that have to get the teens up out of bed. Much of society is sleep deprived and ages 14-24 are some…

    Another thing is that teenagers sleep schedules can vary greatly, some people sleep only a couple hours a night, and some sleep more than 8 hours every night. I couldn’t really use my last question about GPA, because it would again have to be specific to someone, so I would really need all three answers together from each person to form a strong hypothesis. But from the information I have, my hypothesis would be that those who sleep an average of eight hours or more a night, will get good grades and do well in school (my positive correlation). Those who sleep very little will get worse grades (negative…

    Across Surfs I and II, more than three accommodations of youths who went to sleep at 10:45 a.m. or later during the school year or 2:30 a.m. or later during the summer reported sleeping fewer than the recommended 9 hours. A straight importance of lack of sleep has been shown in new studies in which sleep limit has resulted in reduced information and memory performance in timely youth (Curcio et al., 2006). Answers underscore the meaning of evaluating and monitoring sleep time in youths and the importance of interference plans that target sleep times in an exertion to decrease associated functional impairments, and advance academic.…

    Starting later in the morning will mean teens can get the adequate amount of sleep, better grades, and overall better health. With 60% of teens complaining about being tired during the school day it’s pretty obvious they aren’t getting enough sleep. The average teen needs at least eight to ten hours of sleep every night, however, very few actually get that much sleep. A teenagers biological clock naturally makes them stay up later and wake up later, but when schools are starting as early as seven a.m. it’s going against what their bodies naturally want to do. When schools have pushed back the start time in the morning they have found teens are less likely to become tires throughout the day.…

    Hill et al. (2006) conducted a randomized, double-blinded, placebo-controlled study to investigate the difference between β-Alanine supplementation after 4 and 10 weeks and the effect on intense cycling capacity. 25 fit undergraduate and postgraduate fit male participants from the University of Chichester, characterized by low economy and low meat consumption, liberally volunteered to participate. Subjects were not taking any dietary supplements and refrained from supplements 6 weeks before the study. The subjects continued their normal training and diet throughout the study.…

    Stratified randomization was employed by assigning the first 20 clients to either an EMDR group or an EMDR group without the eye movements (Albright & Thyer, 2009). The therapist had completed level two EMDR training, but the treatment was not standard EMDR protocol because there were only two sessions used (Albright & Thyer, 2009). On the post-test no significant differences were found between all conditions, and it was indicated that after a six month follow up there was a reduction of treatment effects in this study’s participants (Albright & Thyer,…

    Due to increased discussion of the outcomes by doctors and nurses not included in the study, the study was shut down and it was suggested that the experimental treatment (alternating between cranial cup and moldable positioner) be offered to all remaining participants. Results before the study was shut down were still included in the paper. For the feasibility portion of the research, the hours per day the cranial cup was used was measured at a mean of 10.7 hours, a number lower than the 12 hours expected, but still adequate to see changes in the infants. The safety worries associated with the use of the cranial cup were shown to be wrong as there was no significant difference in the events seen while using the cranial cup vs. using the moldable positioner. As for the effectiveness of treatment, 46% of infants that used only the moldable positioner were found to have abnormal measurements upon discharge, while only 19% of the infants in the experimental group had abnormal measurements when discharged from their stay at the hospital.…
