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? Processing speed and RAN uniquely predict basic calculation fluency, while visuo-spatial sketchpad, reasoning, and oral language uniquely predict written arithmetic, and central executive, reasoning, processing speed, and oral language uniquely predict word problems. → Cowan 2014

q3 · i? · associational · r2

Fixed-order regression analyses for written arithmetic in 258 third graders. When domain-general factors were entered first, five factors uniquely accounted for variance; when entered last, only visuo-spatial sketchpad, reasoning, and oral language remained significant, each accounting for 1%.

"When entered first (Models A-1 and B-1), the unique predictors are visuo-spatial sketchpad (2%, t = 2.97, p = .003), central executive (1%, t = 2.11, p = .036), reasoning (4%, t = 4.08, p < .001), RAN (1%, t = 2.05, p = .041), and oral language (2%, t = 2.88, p = .004)"
