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? On the two executive-loaded NVWM tasks (Spatial Span Backward and Odd One Out), non-native signers scored significantly more poorly than hearing children, with native signers not differing from hearing children. → Marshall C 2015
Evidence¶
Marshall C 2015¶
Marshall C, Jones A, Denmark T, Mason K, Atkinson J, Botting N and Morgan G (2015) Deaf children's non-verbal working memory is impacted by their language experience. Front. Psychol. 6:527. https://doi.org/10.3389/fpsyg.2015.00527
q3 · i? · associational · r2
ANCOVAs controlling for age and WASI matrix reasoning compared deaf native signers (N = 8), deaf non-native signers (N = 19), and hearing children (N = 28) on NVWM tasks. For the Odd One Out task, "the only group difference being between the non-native signers and the hearing group, p = 0.020."
"Likewise, for the Odd One Out task, there was a significant effect of group, F(2, 54) = 4.187, p = 0.021, with the only group difference being between the non-native signers and the hearing group, p = 0.020."
Discussion¶
Related Claims¶
- Hearing children significantly outscored the deaf group as a whole on Spatial Span Backward and Odd One Out — a broader claim this one bears on
- Deaf children's working memory disadvantage is task-dependent: no group differences on Spatial Span Forward or narrative measures — a narrower finding that bears on this claim
- Vocabulary scores predicted executive-loaded non-verbal working memory scores beyond age and non-verbal reasoning — related
- All three groups differed significantly on expressive vocabulary, with non-native signers scoring lowest — related
- Native signers (children of at least one Deaf parent) outperform non-native signers on ASL syntactic judgment and analogical reasoning tasks — related
