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? Memory performance declined significantly across initial, pre-nap, and post-nap tests, and pre-nap recall error was significantly less than uniform random placement. → Nathan W. Whitmore 2024

Nathan W. Whitmore, Erika M. Yamazaki & Ken A. Paller. (2024). Targeted memory reactivation with sleep disruption does not weaken week-old memories. npj Science of Learning 9, 64. https://doi.org/10.1038/s41539-024-00276-0
q3 · i? · causal · r2
One-way repeated-measures ANOVA over the three tests in the main experiment (n = 18 analyzed); post-hoc corrected comparisons showed significant decline from the initial test, and pre-nap versus post-nap error did not differ (p = 0.53).
"Comparing the initial, pre-nap, and post-nap memory tests revealed a signi ficant test effect [ F(2,51) = 25.8, p < 0.001]."

q3 · i? · causal · r1
Comparison of observed pre-nap error against 1000 simulated participants placing objects at uniformly random locations; participants retained knowledge of object locations after the 7-day delay.
"recall error on the pre-nap test was signi ficantly less than that expected from uniform random placement [uniform random mean error ± SEM = 19.4 cm ± 1.1, t(1017) = 29.1, p < 0.001"
Discussion¶
Learner Variables¶
- Long-Term Memory — outcome: instruction changes it
Related Claims¶
- The TMR-SD effect did not differ for objects with low versus high pre-nap spatial error, ruling out memory strength as the explanation — related
- Children retain trained word-object and letter-sound associations four to six months after the intervention — related
