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 PoorAF group had slower average RTs (2762 ms) than the control group (1759 ms) on the multiplication selection task, with no significant group differences on the other five tasks. → 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 2 (group) by 6 (task) mixed ANCOVA on RTs for correct trials, with LUM scores as covariate, in 18 PoorAF and 18 control children. The group-by-task interaction was significant (F(5, 165) = 2.423, p = .038), and the group effect was "only significant on the multiplication selection task".

"the group effect was not significant ( p > .05) but interacted with the task ( F(5, 165) = 2.423, p = .038). As illustrated in Fig. ( 2), separate analyses for each task revealed that the effect of group was only significant on the multiplication selection task"

Discussion¶

Learner Variables¶

Arithmetic Fact Retrieval — predictor: learners who differ on it differ in outcomes
Long-Term Memory — predictor: learners who differ on it differ in outcomes

A factor analysis separates the multiplication selection task from the other selection tasks on a second component — related
PoorAF and control children do not differ in error rates on the multiplication task, indicating the problems were not too difficult — related
PoorAF children do not differ from controls on tasks retrieving semantic information (words, objects, countries) or verbal routines (proverbs) — related
Fourth graders with poor arithmetic-fact abilities (PoorAF) and matched controls did not differ on a perceptual shape-matching speed task — related
PoorAF children show a significant problem-size effect in multiplication RTs, with a marginally significant stronger problem-size influence than controls — related
