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? The cortisol × alpha amylase interaction is unrelated to math and reading at prekindergarten and to growth in both. → Blair 2015

Model A growth model. The cortisol × alpha amylase interaction at 48 months was "unrelated to math ability at prekindergarten and to growth in math ability"; the same null pattern held for reading. No effect size printed.
"The interaction of cortisol and alpha amylase was unrelated to math ability at prekindergarten and to growth in math ability."
Discussion¶
Related Claims¶
- Directly assessed effortful control at 48 months predicts prekindergarten math but not reading, and not growth in either — related
- Executive function at 48 months positively predicts mathematics ability at prekindergarten, with effects persisting after cognitive covariate controls — related
- Self-regulation effects on letter–word reading are reduced completely after cognitive covariate controls — related
- Combined teacher and parent report of effortful control predicts both prekindergarten math level and growth, persisting through the most stringent model — related
- Executive function at 48 months moderates the preschool-to-kindergarten development of math ability on the ECLS-K Math battery but not the Applied Problems subtest — related
- Preschool executive function positively predicts kindergarten math on both measures, while teacher–child relationship quality shows only a trend-level main effect on ECLS-K Math and none on Applied Problems — related
