Increment in cognitive function by sleep quantity

Abstract
Background
Crisis at the performance of daily activities from sleep deprivation is a universal
occurrence. In the current study, it was hypothesized that the magnitude of sleep over a period
of 24 hours and 7 days was positively correlated with the cognitive performance of human
memory in a statistically significant manner.
Method
A physiologic and cognitive ability of the cohort of 156 participants was evaluated in
the current study. The recent exploration was based on the digit span test, which the participants
of the University of Murdoch performed for the purpose of the experiment. The evaluation
process of the digit span test was based on the average memory span of the participants, who
were aged around 25.65 8.4 years.
Result
The sleep quantity of the respondents was taken into measurement in two scenarios. First,
the respondents' sleep hours for the last 24 hours were measured, and then, total sleep hours of
last seven days were considered. The cognitive ability from the test was found to be positively
associated with average sleep hours for the last seven days, whereas no association was found
between the sleep hours of last night and cognitive performance.

Conclusion
The current work quantified the affirmative impact of rest and sleep on the physiologic
and cognitive performance, but the immediate sleep impact on the cognitive ability did not get
established here.

Sleep quality and duration have always demonstrated a non-monotonic relation with
satisfaction level and success intensity in the work field. Rene Descartes, once in his
"Meditations", exclaimed about the certainty of being awake. Researcher believed the reason for
sleep as fatigue until the mid 20th century. The exact biological reason for turning off from
productive awakening is still a theory of disagreement for the scientist. The benefits of sleep are
apparent, though depleting impacts are still researched for establishing the necessity of rest and
sleep requirement for a human brain. Problems related to fewer hours of sleep or rest have been
the subject matter of focus from many decades. The adverse effect on cognitive performance of
young human brains due to lack of sleep hours has been intensively explained form various
angles by numerous researchers.
Chee et al. in 2008 summarized the adverse effect of sleep deprivation on the
performance of working memory by functional imaging method. Human brains, which got
substantial sleep and rest performed better in functional imaging. Jessica Payne explored the
consequences of sleep quantity on selective memory which was related to emotional scenes. The
time delay of sleeping time of the experimental subjects after the encoding of discerning
consolidation of information was established as a statistically significant factor. The complex

interpretation of the selective information consolidation was found to be positively associated
with the sleep hours of the subjects. The current study was also oriented around the correlation of
the sleep hours and cognitive performance of the subjects, but post sleep impact was evaluated
here. The impairment of the working memory due to sleep deprivation and diminution of the
hippocampal AMPA receptor was analyzed by Roelina Hagewoud et al. in 2010. Hippocampus
related capacity to learn and generation of fresh memories were found to be adversely impacted
by lack of sleep hours. Even, twelve hours of sleep deficiency was scrutinized as an unfavorable
factor for cognitive function.
The complexity in performing the learning and comprehensive responsibilities is
deciphered by the coalesce system of the human brain, which is referred to as the working
memory of the human mind. The accumulation of temporary or short-term information is
believed to be the fundamental conception of working memory (Baddeley, 2010). Lim et al. in
2010 conducted a research to comprehend the impact of lack of sleep on cognitive functions of
the working memory. Six diverse cognitive fields of tests were utilized to measure the counter
effect of short-term lack of sleep of the participants, and wake time was found to be the
statistically significant predicting factor for the effect of sleep deprivation (SD) on cognitive
performances. The extensive implications of insufficiency of sleep were also analyzed by
William Killgore in his thesis on sleep deprivation, in 2010. He discussed the less talked impacts
of SD on the critical cognitive abilities of the brain. Impact on the execution of complex works;
perception supremacy and recollection ability were primarily discussed. The debate based on the
global and selective effect of SD and ability like decision making was found to be unaffected by
lack of proper sleep.
