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 Model 2, the PPVT was not a significant predictor in the overall model (std. = 0.193, t = 1.69, p = .100), although entered alone at step 1 it accounted for 41% of variability in mathematics skills. → Verdine 2014

q3 · i? · associational · r2
Model 2 of the hierarchical regressions, testing the PPVT's influence on later steps. The PPVT alone accounted for adj. R2 = 0.413, F(1, 40) = 29.88, p < .001, but was not significant in the overall model; it was removed from the final model to reduce overfitting.
"In this overall model, the PPVT was again not a significant predictor (std. = 0.193, t = 1.69, p = .100), although when entered alone in the first step it accounts for 41% of the variability in mathematics skills (adj. R2 = 0.413, F(1, 40) = 29.88, p = <.001)."
Discussion¶
Related Claims¶
- EF measures jointly account for 43% of math variance, with inhibition (Tap Test) a significant unique predictor but cognitive flexibility (FIST) not significant in any model — related
- Spatial skills uniquely predict 27% of the variance in preschool mathematics over and above executive function — related
- Executive function and spatial skills jointly predict 70% of the variance in age-4 mathematics performance without an explicit number-knowledge measure — related
- Spatial assembly skill measured at age 3 (TOSA) strongly correlates with mathematics performance one year later at age 4 — related
- Higher-SES preschoolers outperform lower-SES peers on math, spatial, EF, and vocabulary measures, except the Tap Test where the difference is a non-significant trend — related
