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 children with dyslexia, semantics was indirectly related to word decoding efficiency through phonological awareness and rapid naming, with a significant total indirect effect. → van Rijthoven R 2018
Evidence¶
van Rijthoven R 2018¶
van Rijthoven R, Kleemans T, Segers E, Verhoeven L. (2018). Beyond the phonological deficit: Semantics contributes indirectly to decoding efficiency in children with dyslexia. Dyslexia. https://doi.org/10.1002/dys.1597
q2 · i? · associational · r2
Regression-based mediation analysis (Hayes PROCESS, 5,000 bootstrap cycles) with word decoding as dependent variable in 55 Dutch children with dyslexia, covariates verbal working memory, perceptual organization, and age. The "total indirect effect of semantics was significant"; model R2 = 0.691.
"Indirect effects of semantics were found via PA (ab = 0.1712, SE = 0.0615, 95% CI [0.0478, 0.2945]) and RAN (ab = −0.1879, SE = 0.0657, 95% CI [ −0.3197, 0.0560]). The total indirect effect of semantics was significant (0.0421, SE = 0.0173, 95% CI [0.0162, 0.0856])."
Discussion¶
Learner Variables¶
- Long-Term Memory — predictor: learners who differ on it differ in outcomes
- Phonological Awareness — predictor: learners who differ on it differ in outcomes
- Processing Speed — predictor: learners who differ on it differ in outcomes
Related Claims¶
- No significant total or direct effect of semantic knowledge on word or pseudoword decoding in children with dyslexia — related
- Semantic ability correlates with phonological awareness, rapid naming, and both decoding measures in children with dyslexia — a broader claim this one bears on
- Semantic abilities indirectly predict pseudoword decoding efficiency in children with dyslexia via phonological awareness and rapid naming — related
- Child cognitive skills other than initial word reading (phonemic decoding, working memory, phonological awareness, rapid letter naming) did not significantly predict exposures to mastery — related
