Sleep quality is negatively correlated with performance on the Wisconsin Card Sorting Test (WCST), as evidenced by studies showing that poorer sleep leads to reduced cognitive flexibility and increased perseverative errors [1], [2]. This relationship is further examined through measurements of PSQI scores against WCST performance [3] and the investigation of how cultural factors modulate this cognitive impact [4], [5].

claimThe study suggests a potential trend where the negative impact of poor sleep quality on Wisconsin Card Sorting Test (WCST) performance is stronger in Tokyo than in London, though the effect remains inconclusive.
claimCultural factors such as conformity and adherence to rules influence cognitive flexibility and set-shifting abilities in Japanese students, which exacerbates the impact of poor sleep quality on Wisconsin Card Sorting Test (WCST) performance.
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).
claimPoor sleep quality correlates negatively with performance on the Stroop Test and the Wisconsin Card Sorting Test (WCST), suggesting that sleep deprivation impairs attention, executive functions, and information processing efficiency.
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.
measurementThe interaction term (PSQI x City) for the impact of sleep quality on Wisconsin Card Sorting Test (WCST) performance was measured at β = −0.12 with a p-value of 0.09, indicating the result is not statistically significant at the conventional p < 0.05 level.
claimHigher Pittsburgh Sleep Quality Index (PSQI) scores are associated with lower Wisconsin Card Sorting Test (WCST) scores, indicating that poorer sleep quality is linked to poorer cognitive flexibility and more perseverative errors.
