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? A conjunction analysis revealed regions significantly active during both notations of numerical comparison in children and adults: occipito-temporal, precentral, and superior parietal cortices. → Cantlon Jessica F. 2009

q3 · i? · causal · r1
Random-effects conjunction analysis (p < .003, cluster ≥ 8 voxels) of Arabic numeral and dot array contrasts in 14 children and 14 adults. For children the network additionally included inferior frontal gyrus (BA 44) and thalamus (Table 1).
"Regions that exhibited a significant increase in activity during both notations of numerical comparison for children and adults were occipito-temporal (OTC), precentral, and superior parietal cortices."
Discussion¶
Related Claims¶
- Among children, differences in Arabic numeral performance are associated with ratio-dependent BOLD differences in left superior parietal cortex and right OTC, but dot array performance differences show no such brain differences — related
- Children show greater inferior frontal gyrus activity than adults during numerical comparisons, while adults show greater left superior parietal activity than children — related
- Response times in number comparison show group, notation, and ratio main effects, with a larger ratio effect for dot arrays than Arabic numerals — related
- In a number comparison task, adults outperform 6- to 7-year-old children in accuracy, Arabic numerals are easier than dot arrays, and easy 0.5 ratios are easier than difficult 0.8 ratios — related
- Functional connectivity between parietal cortex and occipito-temporal cortex during numerical processing is present in adults but absent in children, whose IFG instead correlates with both regions — related
- The numerical ratio effect in BOLD activity appears in superior parietal cortex in adults but in inferior frontal gyrus, precentral gyrus, and thalamus in children, with no group-level parietal ratio effect in children — related
- In children, the BOLD numerical ratio effect correlates with individual differences in the behavioral ratio effect in right OTC, left superior parietal cortex, and bilateral IFG; no such correlation reaches significance in adults — related
