q3 i? In Experiment 1, blocking dominated study sequence choices even in the motivated and instructed conditions. → Roman Abel 2024

q3 · i? · causal · r2

Framing of Experiment 2 reports the Experiment 1 outcome: "68% of their study sequence choices were blocked (especially within-switches)" even among motivated and instructed learners; no effect size is printed for this descriptive proportion.

"learners applied blocking to a higher extent than interleaving even when motivated to distinguish and informed about the importance of detecting differences for being able to distinguish: Indeed, 68% of their study sequence choices were blocked (especially within-switches)."

Discussion¶

Related Claims¶

• Interleaving Improves Discrimination — related
• Interleaving category examples improves inductive category learning for visual and mathematical materials, but not for expository texts or word categories — a broader claim this one bears on
• Learners overwhelmingly judge blocking more effective than interleaving even when their test performance favors interleaving — related
• In Experiment 1, learners interleaved more only when high utility value of distinguishing was combined with instruction that differences matter, with the two factors interacting rather than showing main effects — related
• In Experiment 1, the extent of informative interleaving did not correlate with category assignment performance, which the authors interpret as a utilization deficiency — related
• Combining utility value of distinguishing with conditional knowledge fosters interleaving of confusable categories (Abel et al., 2024) — related
