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? Quasi-event-related analysis showed both correct and incorrect trials produced robust activity in bilateral IPS and other hyperactive regions, with none of the trial-type differences overlapping operation-specific group differences. → 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
Quasi-event-related re-analysis of subtraction trials in 15 DD participants (one excluded for degenerate design matrix). Incorrect trials showed greater activity in "the right ventral occipito-temporal cortex, bilateral cerebellum, left thalamus and brainstem", regions distinct from the block-design group differences.
"Direct comparison between the trial-types revealed greater activity for incorrect trials in the right ventral occipito-temporal cortex, bilateral cerebellum, left thalamus and brainstem. Crucially, none of these regions showed operation-specific differences in activation between the DD and TD groups in the block-design analysis"
Discussion¶
Learner Variables¶
- Operations and Place Value — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Children with DD show greater brain activation than TD children in parietal, occipito-temporal and prefrontal regions during both addition and subtraction — 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
