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? Group differences emerged on all key variables (ps < .0001), with a linear relation between CPK timing and performance on most measures. → Geary David C. 2019

q3 · i? · associational · r2
ANOVA across the five CPK timing groups on domain-general and quantitative measures, with Tukey's HSD pairwise contrasts. The article reports "a linear relation between CPK timing and performance on most of the domain-general and quantitative measures" (Table 2).
"Analyses of variance revealed group differences on all of the variables (ps < .0001)."
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
- A combination of full scale IQ, letter recognition, enumeration, and discrete quantity discrimination predicts the time of becoming a cardinal principle knower across preschool — related
- Numeral recognition is the strongest predictor of early cardinal principle knower status, with a 1 SD increase yielding a 3.5-fold increase in odds — related
