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? Even after controlling for intelligence and personality, several motivational processes explained additional, unique variance in achievement, totaling about a quarter of the explained variance in school results. → Lavrijsen 2022

q3 · i? · associational · r2
The study of Flemish seventh graders reports that motivational processes "explained additional, unique variance in achievement, totaling about a quarter of the explained variance in school results" after controls for intelligence and personality. The quarter figure is a share of explained variance, not a standardized effect size.
"Yet, even after controlling for intelligence and personality, several motivational processes explained additional, unique variance in achievement, totaling about a quarter of the explained variance in school results."
Discussion¶
Related Claims¶
- Intelligence and need for cognition are strong predictors of academic achievement in Flemish seventh graders — related
- Academic self-concept relates most strongly to achievement, with achievement goals, achievement motivation, autonomous motivation, and effort beliefs each adding unique variance — related
