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 i0 Across pooled outcomes, the acute gain from pre- to post-test does not differ significantly between low (blocked) and high (random/serial) CI practice (ES = 0.1, p = 0.35). → Achraf Ammar 2024

q4 · i0 · quant-synthesis · r3
Multilevel (three-level) meta-analysis of 36 included studies pooling 183 performance outcomes from healthy participants (total 1135; low CI n = 572, high CI n = 563). The pooled acute gain comparison showed "No statistically significant overall difference" with ES = 0.1, p = 0.35; mean gains were 28.9 ± 59.5% (low) vs 27.9 ± 52.8% (high).
"No statistically significant overall difference was detected for “Δ pre-post” between low (blocked) (28.9 ± 59.5%) and high (random/serial) (27.9 ± 52.8%) CI (effect size (ES) = 0.1, p = 0.35)."
Discussion¶
Related Claims¶
- Age moderates both CI effects and female proportion moderates the acute CI effect, while other tested variables do not — related
- 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
- High CI practice shows a statistically significant but small advantage in Δ post-retention change favoring high CI — related
