London is the location of a study population used to evaluate performance on the Stroop Color and Word Test, as evidenced by comparative cognitive assessment data [1], [2] and correlation analyses between sleep quality and test scores [3], [4], [5].

measurementIn the moderation analysis of university students in Tokyo and London, the interaction terms for the Stroop Test (β = -0.10, p = 0.21), Raven's Progressive Matrices (RPM) (β = -0.05, p = 0.32), and Wisconsin Card Sorting Test (WCST) (β = -0.12, p = 0.09) were not statistically significant.
referenceThe study 'Investigating the impact of sleep quality on cognitive functions' utilized a moderation analysis to test whether the relationship between sleep quality (PSQI scores) and cognitive performance (measured by RAVLT, Stroop Test, RPM, and WCST) differs significantly between university students in Tokyo and London.
measurementUniversity students in London outperformed university students in Tokyo on cognitive assessments, including the RAVLT (56.6 vs 53.8), Stroop Test (78.4 vs 73.2), RPM (28.7 vs 27.5), and WCST (54.7 vs 50.1).
imageThe study comparing Tokyo and London students found the following Pearson correlation coefficients (r) between PSQI scores and cognitive measures: RAVLT (Tokyo: -0.40, London: -0.25), Stroop Test (Tokyo: -0.35, London: -0.20), RPM (Tokyo: -0.30, London: -0.15), and WCST (Tokyo: -0.42, London: -0.28).
measurementIn a moderation analysis of university students in Tokyo and London, the interaction term (PSQI x City) for the Stroop Test was β = -0.10 (SE = 0.08, t = -1.25, p = 0.21).
measurementThere is no statistically significant difference in Stroop Test performance between students in Tokyo and London when sleep quality is controlled (β = 0.15, p = 0.10), and the interaction between PSQI scores and city location on Stroop Test performance is not significant (β = −0.10, p = 0.21), suggesting the effect of sleep on attention is consistent across both cities.
measurementPoorer sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), is significantly associated with slower Stroop Test performance (β = −0.25, p < 0.001) across both Tokyo and London student populations.
measurementThere is no statistically significant difference in Stroop Test performance between students in Tokyo and London when sleep quality is controlled for (β = 0.15, p = 0.10).
measurementThe correlation between Pittsburgh Sleep Quality Index (PSQI) scores and Stroop test performance is −0.35 (p < 0.001) for students in Tokyo and −0.20 (p < 0.01) for students in London.
measurementUniversity students in Tokyo scored lower on the Stroop Test with a mean of 73.2 (SD = 11.5) compared to university students in London, who scored a mean of 78.4 (SD = 12.8).
measurementThe correlation between PSQI scores and Stroop Test (attention and executive function) performance is -0.35 in Tokyo and -0.20 in London.
measurementThe relationship between Pittsburgh Sleep Quality Index (PSQI) scores and Stroop Test performance does not differ significantly between students in Tokyo and London (β = −0.10, p = 0.21).
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.
measurementThe correlation between Pittsburgh Sleep Quality Index (PSQI) scores and Stroop Test performance is −0.35 in Tokyo and −0.20 in London.
claimA study investigating university students in Tokyo, Japan, and London, UK, found significant negative associations between sleep quality (measured by the Pittsburgh Sleep Quality Index) and cognitive performance across domains including verbal learning and memory (RAVLT), attention and executive function (Stroop Test), non-verbal reasoning (RPM), and cognitive flexibility (WCST).
