Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? After full standard practice, weekly 40-second reactivations produced a smaller performance decline at 30-day retention than no reactivations. → Gilad Schrift 2022

q3 · i? · causal · r2
Experiment 2, a 2x2 repeated-measures ANOVA on recall score with Session (Post-training retest, Retention) and Group (Reactivations, Control); the Reactivations group's decline (−12.99 ± 3.48 S.E.) was smaller than the Control group's (−30.03 ± 5.95 S.E.). No effect size is printed.
"a signi ficant Session x Group interaction (F1,35 = 6.26, P = 0.017) indicated that the decline in performance in the Reactivationsgroup (mean post-training retest – retention score change= −12.99 ± 3.48 S.E., t(18)= −3.72, P = 0.002, paired t-test) was smaller than in the Control group (mean score change= −30.03 ± 5.95 S.E., t(17)= −5.05, P = 0.0001, paired t-test)"
Discussion¶
Related Claims¶
- Without reactivations, numeric fact memory deteriorates significantly between test and retest — related
- Brief passive reactivations induce significant learning gains in numeric fact recall at retest 8 days after encoding — related
- Brief reactivations significantly reduce recall reaction times, while controls show no RT change — related
- Retention declines with interval (time-dependent forgetting) across images, details, and details-per-image measures — 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 — related
- Descriptive reactivations significantly improve free recall of images compared with distractor and no-reactivation controls — related
- Only descriptive reactivation improves memory precision (correct details per recalled image) — related
