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.
q4 i1 An overall significant difference in Δ post-retention favors high CI practice, but the effect size (ES = −0.35) is small. → Achraf Ammar 2024

q4 · i1 · quant-synthesis · r3
The same multilevel meta-analysis of 36 studies found "An overall significant difference (p = 0.001) in favor of high CI practice" for Δ post-retention, with a small printed effect size (ES = −0.35), which the authors judged "not large enough" to yield greater long-term gain.
"An overall significant difference (p = 0.001) in favor of high CI practice was detected in “Δ post-retention.” However, this difference was not large enough (ES = − 0.35) to produce an overall greater long-term gain"
Discussion¶
Related Claims¶
- High and low CI practice do not differ significantly in overall relatively permanent gains (Δ pre-retention) — related
- Only 20% of pooled performance outcomes agree with the paradoxical contextual interference effects — related
- Low (blocked) and high (random/serial) contextual interference practice do not differ significantly in acute skill gains (Δ pre-post) in PE and sports contexts — related
