Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Mean performance level predicted the random effect of morning sleep quality on performance, indicating the sleep quality effect was particularly pronounced for children with lower average performance. → Könen 2015
Evidence¶
Könen 2015¶
Könen, T., Dirk, J., & Schmiedek, F. (2015). Cognitive benefits of last night's sleep: daily variations in children's sleep behavior are related to working memory fluctuations. Journal of Child Psychology and Psychiatry, 56(2), 171–182. https://doi.org/10.1111/jcpp.12296
q3 · i? · associational · r2
Level-2 analysis predicting the significant random effect of morning sleep quality from between-person variables (age, mean time in bed, bedtimes, ease of getting up, sleep-debt propensity). Only mean performance was predictive; the other predictors were not (ps > .23).
"However, mean performance accounted for 31% of the random effect variance ( b = /C0.29, SE = 0.14), which indicates that the effect of sleep quality was particularly pro- nounced for children with lower average perfor- mance levels."
Discussion¶
Related Claims¶
- Elementary school children show substantial day-to-day within-person fluctuations in sleep quality, time in bed, daytime tiredness, and working memory performance
- Previous night's sleep quality and time in bed predict children's morning working memory performance fluctuations — a broader claim this one bears on
- Current daytime tiredness predicts children's afternoon working memory performance fluctuations — related
- Elementary school children show substantial within-person day-to-day fluctuations in working memory performance in the school context — related
