Sleep quality is directly linked to executive function, as deficits in the former consistently impair cognitive domains including executive functions [1], [2]. Research demonstrates that poor sleep quality negatively correlates with performance on standardized tests of executive function like the Stroop Test and WCST [3], [4].

claimPoor sleep quality impairs attention, memory, executive functions, and overall cognitive performance, as documented by Leong and Chee (2023).
claimStrained cognitive resources due to subpar sleep quality can hinder attention, executive functions, and information processing efficiency, which diminishes academic performance.
claimPoor sleep quality impairs attention, memory, executive functions, and overall cognitive performance, as documented by Leong and Chee (2023).
claimDeficits in sleep quality are consistently linked to impairments in key cognitive domains, including attention, memory, and executive functions.
measurementThe correlation between Pittsburgh Sleep Quality Index (PSQI) scores and Stroop Test performance is -0.28 (p < 0.001), indicating a weak to moderate negative relationship between sleep quality and attention and executive function.
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.
claimSubpar sleep quality strains cognitive resources, which hinders attention, executive functions, and information processing efficiency, thereby diminishing academic performance according to Chew and Cerbin (2021).
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 relationship between Pittsburgh Sleep Quality Index (PSQI) scores and Stroop Test performance does not differ significantly between Tokyo and London (β = −0.10, p = 0.21), suggesting the magnitude of the effect of sleep quality on attention and executive function is consistent across both cultural contexts.
claimStrained cognitive resources resulting from poor sleep quality can hinder attention, executive functions, and information processing efficiency, which ultimately diminishes academic performance.
