Subclaims¶

q3 i2 Partial correlations controlling for the other two EF components, sex, and age remain significant for inhibitory control (r = −0.272) and working memory (r = −0.213) but not for cognitive flexibility (r = −0.086, p = 0.227). → Chen Y 2021

Evidence¶

Chen Y 2021¶

Chen Y, Wang Y, Wang S, Zhang M and Wu N. (2021). Self-Reported Sleep and Executive Function in Early Primary School Children. Front. Psychol. 12:793000. https://doi.org/10.3389/fpsyg.2021.793000

q3 · i2 · associational · r2

Partial correlation analyses in the same 204-child sample, controlling for the other two EF subcomponents plus sex and age. The article reports inhibitory control "its correlation with sleep held" and working memory significant, while cognitive flexibility showed "no significant association with sleep"; equivalence was not tested.

"For inhibitory control, its correlation with sleep held after adding into cognitive flexibility and working memory as controlled variables (r = −0.272, p < 0.001). F or working memory, after additionally controlling for the inhibitory control and cognitive flexibility, its link with sleep was also significant ( r = −0.213, p = 0.004). F or cognitive flexibility, however, there was no significant association with sleep after additionally controlling for the other two EF subcomponents (r = −0.086, p = 0.227)."

Discussion¶

Learner Variables¶

• Sleep — predictor: learners who differ on it differ in outcomes
