q3 i? Adults in the Reactivations group obtained significant test-retest score gains after three 40-second passive reactivation sessions. → Gilad Schrift 2022

Gilad Schrift, Dror Dotan and Nitzan Censor. (2022). Brief memory reactivations induce learning in the numeric domain. npj Science of Learning 7:18. https://doi.org/10.1038/s41539-022-00136-9

q3 · i? · causal · r2

Experiment 1, a repeated-measures ANOVA with Session and Group factors on online number-fact retrieval data, followed by paired-samples t-tests. The Reactivations group showed a "mean test-retest score change= 8.48 ± 2.94 S.E." with t(27) = 2.89, P = 0.008; no standardized effect size is printed.

"Post-hoc paired-samples t-tests veri fied that the Reactivations group obtained signi ficant learning gains (mean test-retest score change= 8.48 ± 2.94 S.E., t(27) = 2.89, P = 0.008)"

Discussion¶

Learner Variables¶

• Arithmetic Fact Retrieval — outcome: instruction changes it
