Subclaims¶

q3 i2 A MANOVA found no difference in self-derivation or stem-fact performance between high and low surface-similarity conditions (η² = .06). → Bauer 2020 q3 i0 Endorsement patterns for old, new, and hybrid statements did not differ by surface similarity (η² < .001). → Bauer 2020 (2)

Evidence¶

q3 · i2 · causal · r2

Between-subjects manipulation in Experiment 2: 43 children heard passage pairs with the same main character (high similarity) and 60 with different characters (low similarity). "A MANOVA examining differences in self-derivation and stem fact performance revealed no difference" across conditions (F(92) = 1.30, p = .28, η² = .06).

"A MANOVA examining differences in self-derivation and stem fact performance revealed no difference in open-ended or forced-choice performance across the similarity conditions, F(92) = 1.30, p = .28, η2 = .06."

q3 · i0 · causal · r2

The 2 (surface similarity) × 3 (statement type) mixed ANOVA on Session 2 endorsement found no similarity effect: "patterns of endorsement did not differ as a function of whether the members of the stem-fact passage pairs had the same or different main characters" (Fs < 0.05, ps > .83, η² < .001).

"Contrary to predictions, patterns of endorsement did not differ as a function of whether the members of the stem-fact passage pairs had the same or different main characters (Fs < 0.05, ps > .83, η2 < .001)."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• Children preserve boundaries of separate learning episodes: hybrid statements combining content from two passages are rejected below chance — 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
• Self-derivation through memory integration extends to science curriculum content, with open-ended performance comparable to general-knowledge stimuli — related
• Self-derivation performance is positively correlated with stem-fact memory and predicts retention of self-derived knowledge one week later — related
• Cluster membership showed a strong multivariate effect on standard text-similarity metrics (Pillai's trace = 0.85, F(12, 248) = 15.31, p < 0.001) — related
