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 Slomowitz et al. (2021), stronger vocabulary showed a main effect on word reading and a significant vocabulary × phonological awareness interaction, but the interaction enhanced reading for children with stronger phonological awareness (lower risk), not the higher-risk group. → Slomowitz R. F. 2025

q2 · i? · theoretical · r3
This theoretical paper reports, citing its authors' prior study Slomowitz et al. (2021), a dimensional main-effect and interaction analysis of vocabulary and phonological awareness on word reading. The interaction was labeled a "skill-enhancing effect"; the paper notes its effect size was much smaller than the promotive main effect. No numeric effect size is printed here.
"Instead, stronger vocabulary abilities enhanced word-reading abilities, specifically for children with higher phonological awareness skills (i.e., lower risk group) (Fig. 3)."
Discussion¶
Learner Variables¶
- Phonological Awareness — moderator: an instructional effect differs with it
Related Claims¶
- Promotive factors are associated with positive outcomes equally in low- and high-risk contexts, producing gap-maintaining effects identified via main effects — related
- Protective factors attenuate the effects of risk as risk rises, producing gap-closing effects represented analytically as Risk × Protective Factor interactions — reports the opposite
- Explicit, instructional home numeracy activities acted as protective (not promotive) factors for 1st–2nd grade math performance in Torppa (2025) — related
- Study designs and statistical analyses in literacy resilience research are often insufficient to distinguish promotive, protective, and skill-enhancing factors — related
