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 i3 Final estimated WM accuracy correlated near-perfectly with overall accuracy (r(85) = 0.96), supporting its interpretation as a proxy for the standard aggregation-based measure. → Aaron Cochrane and C. Shawn Green 2021

Aaron Cochrane and C. Shawn Green. (2021). Trajectories of performance change indicate multiple dissociable links between working memory and fluid intelligence. npj Science of Learning. https://doi.org/10.1038/s41539-021-00111-w
q3 · i3 · associational · r2
Correlational analysis in the same 87-participant experiment found a printed correlation of r = 0.96 (CI = [0.93,0.97], BF log3 = 89.19) between overall and final WM accuracy. The authors state this "statistical near-isomorphism" supports interpreting ending accuracy as an index of stable performance.
"the relation between overall and final WM accuracy: r(85) = 0.96, CI = [0.93,0.97], BF log3 = 89.19). This statistical near-isomorphism supports the interpretation that, throughout our results, ending accuracy is an index of stable performance and can be interpreted as a proxy for the standard overall-accuracy measure"
