Subclaims

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? No significant differences were observed for short naps versus either control condition; equivalence was not tested. → Thiago Cabral 2018

Evidence

Thiago Cabral 2018

Thiago Cabral, Natália B. Mota, Lucia Fraga, Mauro Copelli, Mark A. McDaniel and Sidarta Ribeiro. (2018). Post-class naps boost declarative learning in a naturalistic school setting. npj Science of Learning. https://doi.org/10.1038/s41539-018-0031-z

q3 · i? · causal · r2

Null finding from the same 6-week cross-over experiment, Table 1 reports Wilcoxon p values for short-nap trials and subjects ranging from 0.3631 to 0.8988, none significant. No effect size is printed, so the magnitude is unknown (impact i?); non-significance does not show that short naps have no effect, and no equivalence test was run.

"No significant differences were observed when short naps (<30 min) were considered (Fig. 1d, e)."
