Subclaims¶

q3 i? Initial WM accuracy had no convincing evidence for a relation with Gf (BFlog3 = 0.18); no effect size was printed. → Aaron Cochrane and C. Shawn Green 2021

Evidence¶

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 · i? · associational · r2

In the 87-participant experiment, Bayesian correlation of initial WM accuracy with Gf found "no convincing evidence for a relation with Gf (BF log3 = 0.18)". Equivalence was not tested; only a Bayes Factor is printed, so no effect size is reported.

"In examining the links with Gf, initial WM accuracy had no convincing evidence for a relation with Gf (BF log3 = 0.18)."

Discussion¶

Learner Variables¶

• General Cognitive Ability — predictor: learners who differ on it differ in outcomes
