Subclaims¶

q3 i3 A main effect of statement type on endorsement (η² = .65) showed children endorsed old statements above chance and rejected both new and hybrid statements below chance, indicating episode boundaries were preserved rather than blended. → Bauer 2020

Evidence¶

Bauer 2020¶

Bauer, P. J., Esposito, A. G., & Daly, J. J. (2020). Self-derivation through memory integration: A model for accumulation of semantic knowledge. Learning and Instruction. https://doi.org/10.1016/j.learninstruc.2019.101271

q3 · i3 · causal · r2

Recognition test one week after learning in Experiment 2 (103 children). A 2 × 3 mixed ANOVA found "a main effect of statement type, F(2, 100) = 92.39, p < .001, η2 = .65." Old statements were endorsed above chance (mean difference .20); new and hybrid statements were endorsed below chance (mean differences −.17 and −.10).

"there was a main effect of statement type, F(2, 100) = 92.39, p < .001, η2 = .65. Follow-up pairwise comparisons with Bonferroni corrections revealed significant differences in children's rates of endorsement of all three statement types."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• Children's confidence in endorsing statements indicates they were not confused by hybrid statements — related
• Surface-feature similarity of passage pairs does not affect self-derivation performance or patterns of episode-detail endorsement — related
• Second-grade children self-derive new factual knowledge through integration of separate yet related learning episodes in classroom settings — a broader claim this one bears on
