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? Time 1 expressive vocabulary was a significant predictor of both phonological awareness and early orthographic knowledge in block 3, but lost significance when the two inhibitory control measures entered in block 4. → Gandolfi 2021

Gandolfi, E., Traverso, L., Zanobini, M., Usai, M. C., & Viterbori, P. (2021). The longitudinal relationship between early inhibitory control skills and emergent literacy in preschool children. Reading and Writing. https://doi.org/10.1007/s11145-021-10131-y
q2 · i? · associational · r2
In the same hierarchical regressions on the whole sample, vocabulary entered in block 3 was significant for both outcomes (phonological awareness Beta = .392, p = .005; orthographic knowledge Beta = .404, p = .008), but in the full block 1–2–3–4 model its coefficients dropped to non-significance (Beta = .256, p = .092; Beta = .205, p = .208).
"Although early expressive vocabulary was also a significant predictor for both outcomes, when inhibitory control measures were added to the model, it was no longer significant."
Discussion¶
Learner Variables¶
- Executive Function — predictor: learners who differ on it differ in outcomes
- Reading and Language — predictor: learners who differ on it differ in outcomes
- Vocabulary — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Interference suppression assessed at 28–36 months is the only significant predictor of early orthographic knowledge at 4–6 years in the full regression model — related
- Early interference suppression, but not response inhibition, correlates with emergent literacy measures in both 4–5- and 5–6-year-old subsamples — related
- In toddlerhood, interference suppression correlates with expressive vocabulary after controlling for age, whereas response inhibition does not — related
