q4 · i? · quant-synthesis · r3

Descriptive synthesis across the 36 included studies' 183 pooled outcomes: "Δ in only 37 performance outcomes (20%) agreed with the paradoxical CI effects"; no effect size is printed for this proportion, so it is reported as a descriptive yield.

"Out of 183 overall pooled outcomes, Δ in only 37 performance outcomes (20%) agreed with the paradoxical CI effects on the acquisition or the relatively permanent gains."

Related Claims¶

• 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
• High and low CI practice do not differ significantly in overall relatively permanent gains (Δ pre-retention) — related
• High CI practice shows a statistically significant but small advantage in Δ post-retention change favoring high CI — related
• Age moderates both CI effects and female proportion moderates the acute CI effect, while other tested variables do not — related
