This study is done to see if daytime naps with only NREM sleep has an effect on memory The unit is being studied in this test is one subject s memory The population of the experiment is all undergraduate students of diverse ethnic composition and the sample was 39 of those undergraduates until 6 were excluded making the sample 33 students 11 male and 22 female There were two different treatments done to the subjects in this test The rst treatment is the subjects took a nap after they were trained on the memory tasks The second treatment is the subjects had to stay awake after they were trained After three to three and a half hours the subjects were then retested on the memory tasks after the initial training When it comes to ethics of this experiment I believe that this study did a good job at meeting all the criteria All the subjects were shown the laboratory sleep chambers signed the consent form and completed a demographic information form The study did a great job on con dentiality because no personal details about the subjects were published I did not read anything about a review board in the experiment The author could have mentioned something about the professionals on scene that were supervising the sleep study or how they determined the safety of the study The act of counterbalancing is important in this experiment because it tells us whether taking a nap actually helps with the memory Since we have no way to tell directly if taking a nap helps memory or not the same memory tasks were given to both groups of subject to see which group retained them better This keeps us from having confounding variables In table one the 95 con dence interval for total sleep time is 41440ltnlt55120 We nd this by taking the mean 4828 plus for upper boundminus for lower bound 19695 Cl times 349 SEM They say there is no differences between the nap and nonap subjects on sleep the night before because the nap subjects are awake longer before studying than the nonap sujects So this offsets the difference in sleep the night before Results have shown that sleep plays a special role in memory processing Subjects acquired the tasks and the way in which the information was acquired much better after an NREM day time nap
