Subclaims¶

q3 i? Children with CI had significantly longer response latencies than NH controls in the multiplication verification task (3516 ms vs. 2537 ms) with no group differences in error rates or error-type profiles. → Pixner 2014 q3 i? Children with CI were generally slower in the subtraction choice reaction task (6691 ms vs. 5265 ms), with no reliable borrowing or group×borrowing effects on latencies. → Pixner 2014 (2)

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

PC-administered multiplication verification task with 80 one-digit problems in 45 CI and 49 NH children; ANOVA on latencies with CE functioning as covariate showed "latencies of children with CI were longer than those of NH controls". Error-rate ANOVAs revealed no significant effects (all F < 1).

"the reliable main effect of participant group [F(1,91) = 9.45, p < 0.01] indicated that latencies of children with CI were longer than those of NH controls (3516 ms vs. 2537 ms, respectively"

q3 · i? · associational · r2

Two-digit subtraction choice reaction task (40 problems) in the same matched groups; ANOVA on latencies with CE covariate found only the group main effect reliable, with "responses of children with CI responded were generally slower". Borrowing and interaction effects on latencies were not reliable (both F < 1.26).

"For response latencies only the main effect of participant group was reliable [F(1,91) = 12.82, p < 0.01]. This indicated that responses of children with CI responded were generally slower as compared to the responses of the control group (6691 ms vs. 5265 ms, respectively)."

Discussion¶

Related Claims¶

• The subtraction borrowing effect is more pronounced in children with cochlear implants than in hearing peers
• Children with cochlear implants show an increased rate of dyscalculia indications on a standardized arithmetic test
• In children with cochlear implants, hearing age correlates with fewer non-table multiplication errors and faster borrow subtraction, unlike in hearing peers
• Number line estimation error increases more strongly for children with cochlear implants when the range extends from 0–100 to 0–1000
• Adolescents with ADHD respond more slowly than non-ADHD peers across all conditions, and color-shape binding slows responses in both groups — related
