Subclaims¶

q2 i3 High-fidelity trials showed higher recall than low-fidelity trials (0.50 ± 0.17 vs 0.45 ± 0.18; F(1, 21) = 13.712, p = 0.001), with a printed partial eta-squared of 0.395; the effect was significant at both T4 and T5. → Joey Ka-Yee Essoe 2022

q2 · i3 · causal · r2

In the fMRI experiment (n = 22 analysed, all dual-context), a representational similarity analysis quantified context reinstatement per trial; "high representational fidelity trials (0.50 ± 0.17)" showed better recall than low-fidelity trials, with a printed partial eta-squared of ηp2 = 0.395 (F(1, 21) = 13.712, p = 0.001).

"A main effect of representational fidelity was observed (RM- ANOVA, F(1, 21) = 13.712, p = 0.001, ηp 2 = 0.395; see Supplementary Note 2), where high representational fidelity trials (0.50 ± 0.17) were associated"

Discussion¶

Learner Variables¶

• Long-Term Memory — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Congruent mental reinstatement of the learning context enhanced short-delay recall transfer in a non-VR setting, regardless of learning-context group — related
• After one-week delay, high-fidelity reinstatement benefited recall only following incongruent pre-recall reinstatement prompts, suggesting a desirable-difficulty effect — related
• Response format (overt vs. covert retrieval) did not affect final cued recall in spaced retrieval practice, and list structure (blocked vs. random; proportion of overt trials) did not moderate the effect. — related
• Overt retrieval practice produces higher delayed recall of definitions than covert retrieval practice for learners studying declarative concepts — related
• Transfer across response formats is incomplete: practicing terms benefited definition recall, but practicing definitions showed no overt-over-covert advantage on a term test — related
