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.

q2 i? In hierarchical regression analyses, both WMC and intelligence explained a significant amount of additional variance in all measures of academic achievement at the very beginning of school, after controlling for age, sex, and SES. → Schneider Wolfgang 2017

q2 · i? · associational · r2

Hierarchical regression analyses of the LOGIC longitudinal sample (assessments at ages 6, 8, 10, 18, 23) predicting reading, spelling, and math, with multiple imputation for missing data. The article reports that "IQ and WM turned out to be reliable predictors of academic achievement" when domain knowledge was not included.

"As a main result of various regression analyses, IQ and WM turned out to be reliable predictors of academic achievement, both in early and later developmental stages, when previous domain knowledge was not included as additional predictor."
