Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? In Experiment 3, without memory ratings, retrieval outperformed restudy at all practice frequencies (1, 2, or 3 encounters across the LPSs). → Higham 2023

q2 · i? · causal · r3

Experiment 3 removed the memory rating altogether and compared restudy and retrieval performance for items encountered once, twice, or thrice across the three LPSs. Per the article's summary, "retrieval was superior to restudying regardless of the number of times the items were encountered". No effect size was printed in the supplied text.

"The results showed that retrieval was superior to restudying regardless of the number of times the items were encountered across the LPSs."

Discussion¶

Learner Variables¶

Long-Term Memory — outcome: instruction changes it

The memory rating requirement moderated the restudy-versus-retrieval pattern: interference on retrieval trials and facilitation on restudy trials both contributed to the restudy superiority. — related
