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? In stepwise regression, only the VSSP uniquely predicted nonsymbolic approximate addition, consistent with a mental-model solution. → Xenidou-Dervou 2014

Xenidou-Dervou, I., van der Schoot, M., & van Lieshout, E. C. D. M. (2015). Working memory and number line representations in single-digit addition: Approximate versus exact, nonsymbolic versus symbolic.

q3 · i? · associational · r2
Stepwise multiple linear regression on the nonsymbolic approximate task with WM and number line predictors; "the VSSP, t(102) = 2.83, p = .006, was the best and only unique predictor". The task did not correlate with either number line measure.
"Results showed that the VSSP, t(102) = 2.83, p = .006, was the best and only unique predictor of nonsymbolic approximate addition."
Discussion¶
Learner Variables¶
- Number Sense — predictor: learners who differ on it differ in outcomes
- Spatial Ability — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Nonsymbolic exact addition is predicted by the VSSP plus the CE and symbolic number line estimation, suggesting an alternate transcoding to the symbolic code — related
- Characteristic distance effects occur in both nonsymbolic and symbolic single-digit approximate addition — related
- Symbolic approximate addition is predicted by nonsymbolic number line estimation, the VSSP and the CE, consistent with transcoding to the nonsymbolic code — reports the opposite
- Symbolic exact addition is predicted by symbolic number line representation and the phonological loop, reflecting phonological storage of numerical information — related
- More accurate symbolic number line representations relate to better performance in exact, but not approximate, addition formats — related
