The Stroop Color and Word Test is explicitly used as a measurement tool for attention and executive function, as described in [1] and [2]. Furthermore, research indicates that performance on this test serves as a proxy for assessing how factors like sleep quality impact an individual's attention, as evidenced by [3], [4], [5], and [6].

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.
measurementThe Pittsburgh Sleep Quality Index (PSQI) score significantly predicts performance on the Stroop Test (β = -0.15, p < 0.001) after controlling for demographic variables, indicating that poor sleep quality has an independent negative influence on attention and executive function.
referenceThe Stroop Test assesses attention and cognitive flexibility by requiring participants to name the color of ink used to print words that denote different colors, a method described by Scarpina and Tagini in 2017.
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.
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.
claimPoor sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), is significantly associated with lower cognitive performance across domains including verbal learning and memory (measured by the Rey Auditory Verbal Learning Test), attention and executive function (measured by the Stroop Test), non-verbal reasoning (measured by the Raven's Progressive Matrices), and cognitive flexibility (measured by the Wisconsin Card Sorting Test).
claimThe Stroop Test measures attention and executive function by assessing the ability to inhibit interference, relying on the automaticity of reading to make it challenging for participants to suppress the urge to read the word instead of naming the ink color.
