q3 i2 Pre-sleep performance levels correlated negatively with the TMR benefit in night 3 only. → Göldi 2019

Evidence¶

Göldi 2019¶

Göldi, M. & Rasch, B. (2019). Effects of targeted memory reactivation during sleep at home depend on sleep disturbances and habituation. npj Science of Learning 4:5. https://doi.org/10.1038/s41539-019-0044-2

q3 · i2 · associational · r1

Correlational analysis within the home experiment relating baseline recall before each night to the cued-minus-uncued benefit; night 3 showed "r = −0.31, P = 0.01", while nights 1 and 2 showed no association. Correlation, not causal manipulation.

"We observed a negative correlation between pre-sleep performance levels and TMR benefits during night 3 only ( r = −0.31, P = 0.01). No association was observed during night 1 ( r = 0.12; P > 0.30) and night 2 ( r = −0.20; P = 0.11)."

Discussion¶

Related Claims¶

• In the whole sample, home TMR benefits vocabulary memory only across the third night, for both remembered and newly gained words — 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
• TMR benefits on name recall are negatively correlated with post-cue sleep disruption and post-cue beta-band EEG power, suggesting reactivation depends on undisturbed sleep — 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
• Unsupervised TMR of Dutch vocabulary during three nights of sleep at home does not generally improve memory for cued over uncued words — related
