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? The hearing group significantly outscored the deaf group on Spatial Span Backward and Odd One Out, but not on Spatial Span Forward. → 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
Independent samples t-tests compared the whole deaf group (N = 27) with hearing children (N = 28) on working memory tasks; groups did not differ on age or WASI matrix reasoning, so no covariates were applied. Hearing children scored higher on the two executive-loaded measures.
"the hearing group significantly outscored the deaf group on two measures: Spatial Span Backward, t(53) = 2.345, p = 0.023, and Odd One Out, t(53) = 2.650, p = 0.011. There were no group differences on the Spatial Span Forward task, t(53) = 1.231, p = 0.224."
Discussion¶
Related Claims¶
- Deaf non-native signers scored lower than hearing children on executive-loaded non-verbal working memory tasks, while deaf native signers did not differ from hearing children — a narrower finding that bears on this claim
- Deaf children's working memory disadvantage is task-dependent: no group differences on Spatial Span Forward or narrative measures — related
- Vocabulary scores predicted executive-loaded non-verbal working memory scores beyond age and non-verbal reasoning — related
