q2 i? No TMR effect after 24 h, better cued than uncued performance after 10 days, effect vanished after another 6-8 weeks. → Julia Carbone & Susanne Diekelmann 2024

Julia Carbone & Susanne Diekelmann. (2024). An update on recent advances in targeted memory reactivation during sleep. npj Science of Learning. https://doi.org/10.1038/s41539-024-00244-8

q2 · i? · review · r2

The review attributes to Rakowska and colleagues a bimanual serial reaction time task with sequences cued during NREM sleep. The review reports "better performance for the cued compared to the uncued sequence after 10 days", absent at 24 h and gone by 6-8 weeks; no effect size printed.

"Interestingly, while no effect of TMR was observed after 24 h, subjects showed better performance for the cued compared to the uncued sequence after 10 days, with this effect vanishing after another 6 –8 weeks 12."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

• TMR enhances declarative memory after one night of sleep across paradigms, though some recent studies did not replicate the effect — related
• Auditory TMR cues replayed 1.3x faster than the preceding practice speed yield greater early-phase motor learning gains than same-speed cues — related
• Random-pitch auditory cues show no early learning modulation, underscoring that TMR effects require cue-task congruency — related
• TMR can be used to selectively weaken or promote forgetting of specific memories during sleep — related
