measurementThe correlation between PSQI scores and RAVLT (verbal learning and memory) performance is -0.40 in Tokyo and -0.25 in London.
measurementIn a moderation analysis of university students in Tokyo and London, the interaction term (PSQI x City) for the RPM cognitive measure was β = -0.05 (SE = 0.05, t = -1.00, p = 0.32).
claimThere is an inverse relationship between sleep quality and cognitive performance in both Tokyo and London, where poorer sleep quality (indicated by higher PSQI scores) is associated with lower performance on cognitive tests.
measurementThe relationship between PSQI score and RAVLT performance was significantly stronger in Tokyo (β = −0.35, p < 0.001) compared to London (β = −0.15, p < 0.05), according to a moderation analysis examining cultural context.
measurementIn a moderation analysis of university students in Tokyo and London, the interaction term (PSQI x City) for the WCST cognitive measure was β = -0.12 (SE = 0.07, t = -1.71, p = 0.09).
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).
measurementThe correlation between PSQI scores and RPM (non-verbal reasoning) performance is -0.30 in Tokyo and -0.15 in London.
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.
measurementThe correlation between PSQI scores and RPM (non-verbal reasoning) performance in London is marginally significant at p = 0.04.
claimIn a study comparing university students in Tokyo and London, the impact of sleep quality (measured by PSQI scores) on verbal learning and memory (measured by the RAVLT) is more pronounced in the cultural context of Tokyo compared to London.
measurementIn a moderation analysis of university students in Tokyo and London, the interaction term (PSQI x City) for the RAVLT cognitive measure was β = -0.20 (SE = 0.09, t = -2.22, p = 0.03).
measurementThe correlation between PSQI scores and Stroop Test (attention and executive function) performance is -0.35 in Tokyo and -0.20 in London.
measurementThe effect of city location on Raven's Progressive Matrices (RPM) performance is not statistically significant (β = 0.10, p = 0.10), and the interaction between PSQI scores and city location on RPM performance is not significant (β = −0.05, p = 0.32), indicating the relationship between sleep quality and non-verbal reasoning is consistent across Tokyo and London.
