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? Symbolic numerical magnitude processing significantly predicted arithmetic fact retrieval (p < 0.001) even when controlling for each inhibition task, whereas non-symbolic processing did not (p = 0.407). → Bellon E 2016
Evidence¶
Bellon E 2016¶
Bellon E, Fias W and De Smedt B (2016) Are Individual Differences in Arithmetic Fact Retrieval in Children Related to Inhibition? Front. Psychol. 7:825. https://doi.org/10.3389/fpsyg.2016.00825
q3 · i? · associational · r2
Regression analysis in 86 third graders; the Bayes factor of 13 376 272 for symbolic NMP provided extreme evidence it is an important predictor, and omitting it from the model caused the largest loss of fit (Figure 2).
"Symbolic numerical magnitude processing significantly predicted fact retrieval ( p < 0.001), even when controlling for each inhibition task. Non-symbolic numerical magnitude processing did not significantly predict arithmetic fact retrieval (p= 0.407)."
Discussion¶
Learner Variables¶
- Arithmetic Fact Retrieval — outcome: instruction changes it
- Number Sense — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Inhibition's role in arithmetic fact retrieval may be limited to atypically developing children — related
- Both numerical magnitude processing tasks correlate positively with arithmetic fact retrieval, more strongly for symbolic — related
- Cognitive inhibition is not significantly associated with arithmetic fact retrieval in typically developing third graders — related
- Non-symbolic magnitude processing shows mixed associations with inhibition measures — related
- Inhibition does not uniquely predict arithmetic fact retrieval above numerical magnitude processing — related
- Mathematics achievement is more strongly related to inhibition measured in numerical than non-numerical contexts — related
- Numerical magnitude comparison explains significant unique variance in multiplication fact performance over and above phonological processing, intellectual ability, and general reaction time — related
