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? In the afternoon, 5% of children's daily working memory performance fluctuations were explained, with only tiredness predicting performance over and above daily trends. → 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
Multilevel analysis of the afternoon (around 3:00 pm) measurement occasion in the 31-day smartphone study. The fixed negative effect of tiredness was supported by a likelihood ratio test, but its random effect was not, indicating no reliable differences between children in this coupling.
"In the afternoon, 5% of the children’s daily performance fluctuations could be explained. Only tiredness predicted perfor- mance fluctuations over and above daily trends."
