Investigating the impact of sleep quality on cognitive functions ... frontiersin.org Frontiers 12 facts

claimThe more pronounced negative effect of poor sleep quality on verbal learning and memory in Tokyo students may be attributed to intense academic pressure, longer study hours, or cultural factors.

claimThe negative impact of poor sleep quality on verbal learning and memory is more pronounced among university students in Tokyo compared to those in London, indicating that cultural context moderates the relationship between sleep quality and cognitive performance.

measurementIn a moderation analysis of university students in Tokyo and London, the relationship between sleep quality (measured by PSQI) and RAVLT performance showed a standardized regression coefficient (β) of -0.35 (p < 0.001), indicating that poorer sleep quality is associated with lower verbal learning and memory scores across both cities.

measurementThe interaction between Pittsburgh Sleep Quality Index (PSQI) scores and city location significantly affects Rey Auditory Verbal Learning Test (RAVLT) performance (β = −0.20, p = 0.03), indicating the relationship between sleep quality and verbal memory differs between Tokyo and London.

claimThe relationship between sleep quality and verbal learning and memory is stronger in Tokyo university students than in London university students.

claimInsufficient or disrupted sleep can impair the brain's ability to effectively encode, store, and retrieve verbal information.

claimImproving sleep quality could directly enhance verbal memory and learning abilities, as poorer sleep quality independently predicts lower scores on the Rey Auditory Verbal Learning Test (RAVLT) even when demographic factors are accounted for.

claimResearchers hypothesize that intense academic pressure and long study hours in Tokyo may exacerbate the negative effects of poor sleep on memory consolidation processes, leading to a more pronounced decline in verbal learning and memory performance compared to London.

claimChronic sleep deprivation among Japanese students may disrupt the neural mechanisms underlying memory consolidation, leading to a decline in verbal learning and memory performance.

measurementIn a moderation analysis of university students in Tokyo and London, the interaction between sleep quality (PSQI) and city on RAVLT performance showed a standardized regression coefficient (β) of -0.20 (p = 0.03), suggesting the relationship between sleep quality and verbal learning and memory is significantly different between the two cities.

claimPoor sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), is significantly associated with lower cognitive performance across domains including verbal learning and memory (measured by the Rey Auditory Verbal Learning Test), attention and executive function (measured by the Stroop Test), non-verbal reasoning (measured by the Raven's Progressive Matrices), and cognitive flexibility (measured by the Wisconsin Card Sorting Test).

measurementThe Pittsburgh Sleep Quality Index (PSQI) score significantly predicts performance on the Rey Auditory Verbal Learning Test (RAVLT) (β = -0.20, p < 0.001) after controlling for demographic variables, indicating that poorer sleep quality independently predicts lower verbal memory and learning performance.
