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? Early CPKs had advantages on all quantitative measures controlling FSIQ and executive function; delayed CPKs' deficit remained only on enumeration. → Geary David C. 2019

q3 · i? · associational · r2
Contrast analyses comparing the early CPK group against the four other CPK timing groups, controlling FSIQ and executive function. A parallel analysis of delayed CPKs found their deficit remained only on enumeration (p = .0028); other quantitative deficits were no longer significant (ps > .10).
"The results revealed that the early CPKs had advantages on all of the quantitative measures, above and beyond their advantages in FSIQ and executive function (ps < .0025)."

- 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
