Subclaims¶

q3 i? Descriptive reactivation yielded significantly more correct details than both controls; component reactivation beat the distractor group but not the Control group on details recalled. → MacLeod 2018

MacLeod, S., Reynolds, M. G. & Lehmann, H. (2018). The mitigating effect of repeated memory reactivations on forgetting. npj Science of Learning 3:9. https://doi.org/10.1038/s41539-018-0025-x

q3 · i? · causal · r2

For the correct-details dependent measure, the ANOVA showed a significant reactivation main effect, F(3, 155) = 5.24, p = 0.002. The Descriptive and Component groups "did not signi ficantly differ" from each other (p = 0.19).

"the participants in the Descriptive group remembered signi ficantly more details than the participants in the Distractor group ( p < 0.001) and the no reactivation Control group ( p < 0.05), demon- strating mitigated forgetting. The participants in the Component group remembered more details than the Distractor group ( p < 0.05), but did not signi ficantly differ from the no reactivation Control group ( p = 0.31)."

Discussion¶

Related Claims¶

• Component (category-cueing) reactivations mitigate forgetting relative to distractor controls but do not beat no-reactivation controls on image recall — related
• Only descriptive reactivation improves memory precision (correct details per recalled image) — related
• Descriptive reactivations significantly improve free recall of images compared with distractor and no-reactivation controls — related
• At the 28-day retention interval, both descriptive and component reactivations outperform both controls, with relative gains of 58.8–67.2% for images and over 100% for details — reports the opposite
• Reactivations do not increase false memories: no reactivation effect on falsely recalled images or details — related
