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.
q2 i? SVM classification of EEG features significantly exceeded chance across conditions, with higher accuracy after the second stimulus, peaking around 3 s. → Shin 2025

Shin, G.-H., Kweon, Y.-S., Oh, S., & Lee, S.-W. (2025). Personalized targeted memory reactivation enhances consolidation of challenging memories via slow wave and spindle dynamics. npj Science of Learning 10:47. https://doi.org/10.1038/s41539-025-00340-3
q2 · i? · causal · r2
SVM with RBF kernel, 5-fold cross-validation with 2 repetitions, classifying groups from SW power, spindle power, and SW-spindle coupling; performance exceeded chance (surrogate decoding with 250 label shuffles), peaking near 3 s post-stimulus.
"The accuracy values confirmed the strong discriminative power of these features across all conditions, with classi fication performance exceeding chance levels. Notably, ac curacy values were higher after the second stimulus (2 s) compared to thefirst (0 s), peaking at around 3 s."

- Auditory cueing during NREM sleep elevates slow wave and spindle power relative to no stimulation, with effects concentrated in frontal and central regions — related
- In the personalized TMR group, memory improvement for challenging items correlates positively with SW-spindle coupling (r = 0.70), but no such correlation appears in the All condition or other groups — related
- Personalized TMR improves recall accuracy for the most challenging (L3) word pairs, outperforming both uniform TMR and no-stimulation control in the post-sleep session — related
