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? The TMR-SD effect (cued FR divided by uncued FR) was significantly greater in the prior 1-hour-delay study than in the present 1-week-delay study. → Nathan W. Whitmore 2024

q3 · i? · causal · r1
Cross-study comparison quantifying TMR-SD as the ratio of cued to uncued forgetting ratios, using highly similar procedures differing mainly in the 1-hour versus 1-week post-learning delay. The weakening effect was present only in the 1-hour-delay study.
"the TMR-SD effect differed between the two studies [t(39.84) = 2.99,p = 0.005]; the TMR-SD effect was greater in the prior study than in the present study."
Discussion¶
Related Claims¶
- Whether a cue provoked an EEG-scored arousal did not affect the forgetting ratio of cued objects — related
- Greater sleep disruption in the present study rules out reduced sleep disruption as an explanation for the absent memory weakening — related
- TMR-SD auditory cues presented during sleep did not reliably weaken week-old spatial memories compared to uncued objects — related
- Sleep-stage durations, sleep fragmentation, and pre- and post-cue EEG band power were not significantly correlated with forgetting of cued items or the TMR-SD effect — related
- 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
