claimThere is a stronger negative relationship between sleep quality and cognitive flexibility and set-shifting abilities in Tokyo compared to London.

claimThe magnitude of negative correlations between sleep quality and cognitive performance is consistently larger in Tokyo than in London for all cognitive measures.

claimA study investigating the impact of sleep quality on cognitive functions among university students collected data from 400 participants, with 200 students from Tokyo, Japan, and 200 students from London, UK.

claimA cross-sectional study of 400 university students (200 in Tokyo and 200 in London) investigated the impact of sleep quality on cognitive functions.

claimThe study found that the relationship between sleep quality and verbal learning and memory was stronger in Tokyo than in London, a finding described as novel in the literature.

referenceThe study on sleep quality and cognitive wellbeing in Tokyo and London utilizes Memory Consolidation Theory, Cognitive Load Theory, Circadian Rhythm Theory, and the Stress-Performance Relationship as its theoretical frameworks.

claimThe study found a more pronounced negative relationship between sleep quality and Rey Auditory Verbal Learning Test (RAVLT) performance in Tokyo compared to London, suggesting that cultural factors may modulate the impact of sleep on memory consolidation.

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 impairs the brain's ability to encode, store, and retrieve verbal information, as evidenced by negative correlations between sleep quality and Rey Auditory Verbal Learning Test (RAVLT) performance in Tokyo and London students.

claimThe negative relationship between sleep quality and Wisconsin Card Sorting Test (WCST) performance is stronger in Tokyo than in London, suggesting that cultural factors modulate the impact of sleep on cognitive load.

claimPoor sleep quality has a stronger negative impact on Rey Auditory Verbal Learning Test (RAVLT) performance in Tokyo compared to London, as indicated by a negative coefficient (β = −0.20).

measurementStudents in Tokyo exhibited lower sleep quality than students in London, as evidenced by average Pittsburgh Sleep Quality Index (PSQI) scores reflecting a more significant occurrence of sleep disturbances.

claimThe study investigates the relationship between specific dimensions of sleep quality (duration, consistency, and disturbances) and cognitive performance (memory retention, attention span, problem-solving abilities, and executive functioning) among university students in Tokyo and London.

measurementThe article 'Investigating the impact of sleep quality on cognitive functions among students in Tokyo, Japan, and London, UK' was received on December 2, 2024, accepted on April 30, 2025, and published on May 26, 2025.

claimA comparative analysis of the relationship between sleep quality and cognitive functions in Tokyo and London is essential for developing targeted interventions that address the unique challenges faced by students in these distinct cultural contexts.

claimThe study utilizes a cross-sectional design to examine the influence of sleep quality on cognitive functions in university students from Tokyo, Japan, and London, UK.

claimThe study aims to develop evidence-based recommendations for university-level interventions to improve sleep quality and cognitive outcomes among students in Tokyo and London, focusing on strategies such as sleep hygiene programs, flexible academic scheduling, and stress management workshops.

claimThe study on sleep quality in Tokyo and London students utilizes multivariate regression analyses and structural equation modeling as analytical methods.

measurementThere are negative correlations between sleep quality and performance on the Rey Auditory Verbal Learning Test (RAVLT) among university students in both Tokyo and London.

claimThe study aims to evaluate how academic stress, lifestyle choices (including exercise, social interactions, dietary patterns, and technology use before bed), and cultural factors (including societal expectations, educational systems, and parental influences) mediate or moderate the association between sleep quality and cognitive performance in university students in Tokyo and London.

perspectiveThe study authors recommend that interventions to improve student sleep quality should be culturally tailored, specifically by reducing academic pressure in Tokyo and addressing socioeconomic challenges in London.

claimThe study investigated the impact of cultural factors on cognitive outcomes associated with sleep quality among students located in Tokyo and London.

claimUnderstanding the dynamic of sleep quality and cognitive functions in Tokyo and London requires exploring the Stress-Performance Relationship, the relationship between stress and mental health, and the impact of sleep quality on cognitive functions and mental health.
