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? Across five CPK timing groups, FSIQ, letter recognition, enumeration, and discrete quantity discrimination jointly predict time of becoming a CPK. → Geary David C. 2019

q3 · i? · associational · r2
Longitudinal study of 197 children across two years of preschool; Bayes factor model selection followed by standard regression with age as covariate. The model was "highly significant, R2 = .56, F(5,191) = 48.18, p < .0001" with all predictors significant (ps < .005).
"The overall model was highly significant, R2 = .56, F(5,191) = 48.18, p < .0001, as was each of the predictors (ps < .005)."
Discussion¶
Related Claims¶
- Early CPKs show quantitative advantages beyond their domain-general advantages, while delayed CPKs' quantitative deficits are largely secondary except for enumeration — related
- Deficits in executive function and letter recognition predict delayed cardinal principle knower status — related
- There is a linear relation between CPK timing and performance on most domain-general and quantitative measures — related
