According to the Center for Disease Control and\nPrevention, 1\/3 of adults \u201care not getting enough sleep on a regular basis.\u201d\nThough the reasons\nfor this missed\nsleep vary, the effects of sleep\ndeprivation are similar.\nDespite missed sleep\u2019s\nnegative impact on memory, many students choose to pull all-nighters rather than\ngetting a good night of sleep before a test. Dominique Gosselin et al. conducted\na study to determine the effects of sleep deprivation on semantic memory.\nSemantic memory is associated with common knowledge, such as knowing\nthat grass is green, and is sometimes referred to as \u201cpermanent memory.\u201d Sleep\ndeprivation reduced the test subjects\u2019 semantic memory.<\/p>\n\n\n\n

In the study, 12 college students were tested with 7-8 hours of sleep and again after a night of total sleep deprivation. During the test, the students were given a pair of words, some that were associated and some that were not, and the test subjects had 1.2 seconds to press the \u201cassociated\u201d or \u201cnot\u201d button. Different word pairs were used for the normal sleep and total sleep deprived groups (abbreviated as \u201cNS\u201d and \u201cTSD\u201d). The table compares the performance of the 12 individuals with NS and TSD. Total sleep deprivation decreased the subjects\u2019 ability to efficiently recall semantic memory. The table also compares performance on strongly (such as \u201csky\u201d and \u201cblue\u201d) and weakly associated words (such as \u201ccat\u201d and \u201cpaw\u201d). The NS trial scored an average of 12.7% higher than the TSD trial. Some might argue that 12.7% too small to have any significance, the p-value of 0.04 shows that the difference in scores between NS and TSD are significant and not caused by chance.<\/p>\n\n\n\n

Sleep deprived people struggled to quickly identify\nrelated words, a skill that requires the use\nof semantic memory.\nSleep is a vital component in semantic memory\nrecall. Although semantic memories are not the goal when pulling an all-nighter, the study is important because\nit shows that sleep affects memory recall\nefficiency which is a vital aspect needed to succeed on any test. Without being\nable to efficiently retrieve the information that our brain is storing, we are\nunable to perform our best. So, is it worth it to trade sleep for study time?\nIf you cannot quickly retrieve the newly learned information, the answer is\nlikely no.<\/p>\n\n\n\n
