Subclaims¶

q3 i? 15.6% of children with CI scored below the dyscalculia diagnostic threshold on the HRT basic arithmetic operations scale, though their mean T-scores did not differ from the standardization sample. → Pixner 2014

Evidence¶

Pixner 2014¶

Pixner, S., Leyrer, M., and Moeller, K. (2014). Number processing and arithmetic skills in children with cochlear implants. Frontiers in Psychology 5:1479. https://doi.org/10.3389/fpsyg.2014.01479

q3 · i? · associational · r2

Standardized calculation test (HRT 1–4) administered to the 45 children with CI; seven scored below percentile 10, the ICD-10/DSM-IV dyscalculia cut-off, so "seven children of our experimental group (i.e., 15.6%)" showed dyscalculia indications. Mean T-scores (M = 48.40) did not differ from the standardization sample, t(44) = 0.89, n.s.

"Hence, seven children of our experimental group (i.e., 15.6%) would fall below the diagnostic threshold of developmental dyscalculia."

• Children with cochlear implants are generally slower than hearing peers in multiplication and subtraction but show comparable error profiles
• Number line estimation error increases more strongly for children with cochlear implants when the range extends from 0–100 to 0–1000
• In children with cochlear implants, hearing age correlates with fewer non-table multiplication errors and faster borrow subtraction, unlike in hearing peers — related
• The subtraction borrowing effect is more pronounced in children with cochlear implants than in hearing peers — related
