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? Expressive One Word Picture Vocabulary Test scores were a significant unique predictor of Spatial Span Backward and Odd One Out scores when age and WASI matrix reasoning were controlled. → 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
Multiple regression across all participants (deaf and hearing combined) predicting Spatial Span Backward scores, with age and WASI T-scores entered first. Vocabulary was a significant unique predictor (β = 0.379, p = 0.033); the Language Proficiency Profile was not (p = 0.861).
"Expressive One Word Picture Vocabulary score was a significant unique predictor ( β = 0.379, t = 2.208, p = 0.033), but the Language Proficiency Profile score was not ( β = 0.029, t = 0.176, p = 0.861)."
