Assessment of sleepiness role in working memory and whole-body reaction time.

Background: Sleep provides physical and mental strength, and natural sleep is essential for cell growth, strengthening, stabilizing, and accelerating the improvement of memory function.

Objective: The current investigation aimed to explore working memory influenced by sleepiness and related to whole-body reaction time, in order to identify some facets of the dynamics of this memory. To the best of our knowledge, this triple has not yet been explored in the literature.

Methods: This study cross-sectional, descriptive-analytical was performed on a sample total of 45 volunteer undergraduate academic students were recruited by convenience sampling, including 35 females and 10 males with a mean age of 21.08 ± 1.10 years of old. Data were collected via a demographic checklist, Epworth Sleepiness Scale (ESS) questionnaire, Digital Maze test (for working memory), and visual/auditory whole-body reaction time measurement.

Results: The working memory of each subject was divided into three types:1) thoughtful and precise, 2) Cautious and Conservative, and 3) messy and inaccurate. The triple of working memory, reaction time, and sleep versus sleepiness were all significantly related (P = 0.017-0.05).

Conclusion: The authors concluded that there might be some established infrastructure for adult working memory, while there might be a floating operator of working memory as well; influenced by various parameters, this study was influenced by sleep adequacy and physical readiness.
