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? Reaction times were significantly longer for children with DD than TD children, with no significant main effect of Operation or Group × Operation interaction. → Rosenberg-Lee 2014
Evidence¶
Rosenberg-Lee 2014¶
Rosenberg-Lee, M., Ashkenazi, S., Chen, T., Young, C. B., Geary, D. C., & Menon, V. (2014). Brain hyper-connectivity and operation-specific deficits during arithmetic problem solving in children with developmental dyscalculia. Developmental Science. https://doi.org/10.1111/desc.12216
q3 · i? · associational · r2
Two-way ANOVA on reaction times in the same 16 DD and 20 TD children during addition and subtraction verification. The study found "reaction times were significantly longer for children with DD than for TD children (F(34, 1) = 4.76, p = .036)", with no significant operation effect or interaction.
"reaction times were significantly longer for children with DD than for TD children (F(34, 1) = 4.76, p = .036). Neither the main effect for Operation (F(34, 1) = 1.07, p = .308), nor the Group by Operation interaction (F(34, 1) = 1.58, p = .217) were significant"
Discussion¶
Learner Variables¶
- Learning Disabilities and Developmental Differences — predictor: learners who differ on it differ in outcomes
- Operations and Place Value — predictor: learners who differ on it differ in outcomes
- Processing Speed — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Children with developmental dyscalculia are disproportionately impaired on subtraction accuracy relative to addition, showing a significant group × operation interaction — related
- Arithmetic problem-solving performance improves over 1.2 years in children, with larger gains on standard addition than control problems — related
- Arithmetic deficits in adults with DD concentrate in mental calculation, arithmetical rules, and written calculation, with number comprehension and transcoding preserved — related
- Adults with dyscalculia perform the number comparison task as accurately as controls but respond significantly more slowly — related
- Adults with dyslexia are slower than controls on single-digit arithmetic, with a larger multiplication-minus-subtraction reaction-time difference, even after controlling digit identification speed — related
- Children with developmental dyslexia show a processing speed impairment relative to controls — related
- DD children show operation-specific hyperactivation: greater IPS, superior parietal lobule and fusiform activity during subtraction, while during addition only the right superior parietal lobule differs (lower in DD) — related
- A significant three-way interaction of group, prime type and arithmetic operation governs arithmetic-affective priming, with DD children slower overall than controls — related
- Spatial processing is preserved but slower in developmental dyscalculia, with slow trail-making and mental rotation speed attributed to WM/inhibition impairment — a narrower finding that bears on this claim
