Subclaims¶

q2 i2 Odor TMR at home and school improved vocabulary test performance, with effect sizes d = 0.6-1.2, and works when presented continuously across the night. → Julia Carbone & Susanne Diekelmann 2024 q2 i? Same-odor vs different-odor cueing at home significantly improved memory for a history lesson in secondary students. → Julia Carbone & Susanne Diekelmann 2024 (2)

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 · i2 · causal · r?

The review attributes to Neumann and colleagues a 6th-grade study in which students studied German-English vocabulary with an incense stick at their desk and bedside. The printed effect sizes are "d = 0.6–1.2" in the TMR groups.

"Effect sizes in the TMR groups were quite large (d = 0.6–1.2), indicating that TMR does not only work in a lab environment but also in a regular school setting."

q2 · i? · review · r2

The review attributes to Vidal and colleagues a secondary-school history lesson paired with an odor dispenser at learning and the same vs a different odor during sleep at home. "memory performance of the history class was signi ficantly improved"; no effect size printed.

"When students were presented with the same odor during the night at home, compared to a different odor in the control condition, memory performance of the history class was signi ficantly improved."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• Closed-loop TMR timed to the slow-oscillation up-state improves memory consolidation relative to down-state cueing, though direct up-vs-down comparisons yield mixed results — related
• TMR enhances declarative memory after one night of sleep across paradigms, though some recent studies did not replicate the effect — a broader claim this one bears on
