Sleep quality is directly linked to attention, as deficits in the former consistently impair the latter [1]. This relationship is supported by empirical evidence showing that poor sleep quality correlates negatively with performance on attention-based tasks like the Stroop Test [2], [3], and is documented as a primary factor in cognitive impairment [4], [5].

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).
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.
