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.
q2 i? ROI correlations revealed significant positive correlations between IPS connectivity and reaction time during addition in left supramarginal gyrus, anterior cingulate, right middle frontal and inferior frontal gyri, with no significant correlations during subtraction. → 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
q2 · i? · associational · r2
ROI-based correlation analysis on gPPI t-scores averaged across seeds in the full sample. The study reports "significant correlations between connectivity and reaction time during the addition task in the left supramarginal gyrus (r = .414, p = .012)" and other regions, with worse performance related to greater connectivity.
"there were significant correlations between connectivity and reaction time during the addition task in the left supramarginal gyrus (r = .414, p = .012), anterior cingulate (r = .408, p = .013), right middle frontal (r = .366, p = .028) and inferior frontal gyri (IFG, r = .406, p = .014), with worse performance related to greater connectivity"
Discussion¶
Learner Variables¶
- Operations and Place Value — predictor: learners who differ on it differ in outcomes
Related Claims¶
- DD children fail to disengage the default mode network during demanding arithmetic, showing aberrant coupling with task-positive IPS regions — related
- Children with DD show hyper-connectivity, not reduced connectivity, between the IPS and fronto-parietal and default mode networks during arithmetic — related
