Relatie slaapduur en executief functioneren gemodereerd door temperament bij 9 t/m 11 jarigen?

Children differ in their school performances, which are influenced by their executive functions (EF). The cause of these differences can probably be explained by individual differences in sleep duration and temperament. The moderating effect of temperament on the association between sleep duration and EF and mutual relations have been studied. The sample consisted of 499 ‘normal’ children (228 boys, 271 girls) between 9 to 12 years (M = 10.5; SD = 0.85). Sleep duration is measured by a sleep log, temperament factors Extraversion, Negative Affectivity and Effortful Control by the EATQ-R. EF is divided in working memory (Visual digit span task) and inhibition (PVT Go/No-Go). ANCOVA has showed only an association between shorter sleep duration and less working memory for introvert children and the other way around (F(2, 410) = 5.15, p = .006), but not for neutral extraverted children or high extraverted children. Also other temperament factors did not show moderation effects....Show moreChildren differ in their school performances, which are influenced by their executive functions (EF).

Also other temperament factors did not show moderation effects. Furthermore, shorter sleep was significantly related with less inhibition (r = .12), but with better working memory (r = -.52). Extraverted children differ from introverted children on working memory (F(2, 433) = 3.24, p = .040) and little Effortful Control differs from the average level of Effortful Control (F(2, 436) = 3.55, p = .030). There were no other significant results in this study. This study has shown that school performances are not only influenced by cognitive capacities, but also by sleep and child’s temperament traits.Show less
