Subclaims¶

q3 i? In the L3 difficulty condition, only the personalized TMR group showed significant pre- to post-sleep improvement, and it significantly outperformed both TMR and CNT after sleep. → Shin 2025 q3 i? A significant group × time interaction was observed in the L3 condition, indicating that the benefit of personalized cueing depended on both group and session. → Shin 2025 (2)

q3 · i? · causal · r1

Controlled between-group experiment (12 participants per group) comparing memory accuracy across sessions. In the L3 condition only the personalized group improved, and "personalized TMR performed signific a n t l yb e t t e rt h a nb o t h TMR" and CNT post-hoc.

"Paired t-tests showed improvements in personalized TMR (t11 = -5.68,p < 0.001), but not in TMR (t11 = -1.50,p = 0.161) or CNT (t11 = -1.56,p = 0.148). personalized TMR performed signific a n t l yb e t t e rt h a nb o t h TMR (t22 =3 . 9 6 ,p < 0.001) and CNT (t22 =4 . 4 9 ,p <0 . 0 0 1 )i nt h ep o s t - s l e e p session."

q3 · i? · causal · r2

Two-way ANOVA (group × time) on L3 accuracy in the word-pair memory task; the omnibus interaction F2,66 = 8.91, p < 0.001 was significant, alongside main effects of group and time.

"In the most demanding L3 condition, significant effects of group (F2,66 = 16.54,p < 0.001), time (F1,66 = 20.77, p < 0.001), and their interaction ( F2,66 =8 . 9 1 ,p <0 . 0 0 1 )w e r e observed."

Discussion¶

Related Claims¶

• Personalized TMR improves error correction (higher incorrect-to-correct transitions) and reduces persistence of incorrect responses, mainly for challenging items — related
• TMR efficacy depends on memory strength and task difficulty: benefits concentrate on moderately strong and challenging items, with limited advantage for easy (L1) items — a broader claim this one bears on
• 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
• Auditory cueing during NREM sleep elevates slow wave and spindle power relative to no stimulation, with effects concentrated in frontal and central regions — related
• Full word-pair cues can promote rather than disrupt reactivation when delivered with sufficient spacing and during stable NREM sleep — related
• Multivariate classification of SW power, spindle power, and SW-spindle coupling distinguishes the personalized TMR, TMR, and control groups above chance, peaking around 3 s after cue onset — related
