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 all three ages, neither Go/No-Go nor Nebraska Barnyard performance significantly interacted with trial type in local-cost models (the GNG interaction at 5;3 was near significance, p = .059); nonsignificance does not establish that they are unrelated. → Chevalier N. 2012

q3 · i? · associational · r2
Multilevel local-cost models at ages 3;9, 4;6, and 5;3 found no significant GNG × trial type or NB × trial type interaction at any age (Table 3: GNG p = .566, .424 and .059; NB p = .449, .848 and .204 at 3;9, 4;6 and 5;3; the text quotes only the 3;9 values). The authors conclude that "local costs did not depend on inhibition and working memory in this preschool age range."
"At all ages, neither GNG performance nor NB interacted with trial type (p = .566 and p = .449, respectively), suggesting that local costs did not depend on inhibition and working memory in this preschool age range."
Discussion¶
Related Claims¶
- Higher inhibition and working-memory scores predict better overall Shape School accuracy at some ages, independent of trial type — related
- Inhibition and working-memory performance are associated with mixing costs (goal representation) at ages 4;6 and 5;3 but not at age 3;9 — related
- Task-demand clusters differ in useful age ranges, with perceptual inhibition developing earliest and motivational inhibition latest — related
- Significant mixing and local costs are present at each preschool age, with both decreasing in magnitude from age 3;9 to 5;3 — related
- Perseverators do not differ from non-perseverators in inhibition or working-memory performance at any age — related
