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.

q3 i? At ages 4;6 and 5;3, Go/No-Go and Nebraska Barnyard performance significantly interacted with trial type, with higher scores predicting smaller mixing costs. → Chevalier N. 2012 q3 i? At age 3;9, neither inhibition nor working memory interacted with trial type, indicating no relation to mixing costs at that age. → Chevalier N. 2012 (2)

q3 · i? · associational · r2

Multilevel modeling of Shape School accuracy at ages 4;6 and 5;3 found the GNG × trial type interaction significant (γ = .069, p = .002; γ = .054, p = .011), so "Higher GNG performance resulted in smaller mixing costs"; NB showed parallel interactions (γ = .058, p = .003; γ = .034, p = .022).

"In contrast to the earlier time point, at ages 4;6 and 5;3, GNG performance significantly interacted with trial type (γ = .069, p = .002 at age 4;6; γ = .054, p = .011 at age 5;3). Higher GNG performance resulted in smaller mixing costs."

q3 · i? · associational · r2

At age 3;9 the same multilevel models showed no GNG × trial type or NB × trial type interaction (p = .069 and p = .118), so "mixing costs do not depend on inhibition and working memory at this age."

"At age 3;9, neither GNG nor NB performance interacted with trial type (p = .069 and p = .118, respectively), suggesting that mixing costs do not depend on inhibition and working memory at this age."
