sleep quality ↔ Rey Auditory Verbal Learning Test

Relations (1)

related 3.17 — strongly supporting 8 facts

Sleep quality is negatively correlated with performance on the Rey Auditory Verbal Learning Test (RAVLT), as evidenced by studies showing that poorer sleep quality predicts lower test scores {fact:1, fact:3, fact:8}. This relationship is quantified by a moderate negative correlation [1] and is observed to be modulated by cultural factors in different student populations {fact:2, fact:5}.

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.

measurementHigher Pittsburgh Sleep Quality Index (PSQI) scores, which indicate poorer sleep quality, are associated with lower performance on the Rey Auditory Verbal Learning Test (RAVLT), Stroop Test, Raven's Progressive Matrices (RPM), and Wisconsin Card Sorting Test (WCST) (p < 0.001).

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.

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.

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).

measurementThe correlation between Pittsburgh Sleep Quality Index (PSQI) scores and Rey Auditory Verbal Learning Test (RAVLT) performance is -0.32 (p < 0.001), indicating a moderate negative relationship between sleep quality and verbal learning and memory.

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.

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.
