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? A 1 SD increase in numeral recognition yields a 3.5-fold increase in the odds of being an early CPK, controlling other predictors. → Geary David C. 2019

q3 · i? · associational · r2
Binomial logistic regression contrasting early CPKs (already CPK at preschool start) with all other children in the 197-child sample. The model was highly significant, χ2(4) = 98.91, p < .0001, and correctly classified 88% of children.
"a 1 SD increase in numeral recognition resulted in a 3.5-fold increase in the odds of being an early cardinal principle knower [χ2(1) = 24.19, p < .0001, 95% confidence interval 2.1 to 5.8]."
Discussion¶
Related Claims¶
- There is a linear relation between CPK timing and performance on most domain-general and quantitative measures — related
- Deficits in executive function and letter recognition predict delayed cardinal principle knower status — related
- Preschool one- and two-knowers perform at least 0.5 SDs lower on the kindergarten number sets test than early cardinal-principle knowers — related
- Early CPKs show quantitative advantages beyond their domain-general advantages, while delayed CPKs' quantitative deficits are largely secondary except for enumeration — related
