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? The two groups did not differ in a perceptual shape-matching task requiring no memory retrieval, so the findings did not support a general speed-of-processing deficit explanation (one non-significant task, not a refutation). → Mussolin 2008
Evidence¶
Mussolin 2008¶
Mussolin, C. and Noël, M-P. (2008). Specific Retrieval Deficit from Long-Term Memory in Children with Poor Arithmetic Facts Abilities. The Open Psychology Journal. https://doi.org/10.2174/1874350100801010026
q3 · i? · associational · r2
A second ANCOVA with L3 scores as covariate confirmed a group effect only for the multiplication selection task (F(1, 33) = 11.695, p = .002) and not for the other tasks including the perceptual task. The article states the deficit "was not associated with a global low processing speed".
"Further analyses by task indicated a group effect for the selection task with multiplication problems ( F(1, 33) = 11.695, p = .002), but not for the other tasks (p > .05)."
Discussion¶
Learner Variables¶
- Arithmetic Fact Retrieval — predictor: learners who differ on it differ in outcomes
- Processing Speed — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Children with ADHD perform worse than controls on WISC-IV Coding but not on Coding Copy, indicating deficits beyond graphomotor speed — related
- PoorAF children do not differ from controls on tasks retrieving semantic information (words, objects, countries) or verbal routines (proverbs) — related
- Children with poor arithmetic fact abilities are significantly slower than matched controls only on the multiplication selection task — related
- PoorAF children show a significant problem-size effect in multiplication RTs, with a marginally significant stronger problem-size influence than controls — related
- Adolescents with ADHD respond more slowly than non-ADHD peers across all conditions, and color-shape binding slows responses in both groups — related
