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? Children with small versus large behavioral ratio effects for Arabic numerals differed in BOLD ratio effects in left superior parietal cortex and right OTC; no differences emerged for dot arrays. → Cantlon Jessica F. 2009

q3 · i? · associational · r2
Median-split analysis of children's behavioral ratio effects per notation, examining BOLD ratio effects in conjunction-defined regions. "There was no difference between the two groups of children in ratio-dependent BOLD activity in any of the queried brain regions for dot arrays (all ps > .08)."
"For Arabic numerals, children in the small behavioral ratio effect group exhibited significantly less ratio-dependent BOLD activity compared to children in the large behavioral ratio effect group in left superior parietal cortex and right OTC (Figure 7A and B) but not in frontal cortex (Arabic numerals: p = .15; dot arrays: p = .08)."
Discussion¶
Related Claims¶
- 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
- 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
- Children and adults engage a common network of occipito-temporal, precentral, and superior parietal cortices during numerical judgments of both Arabic numerals and dot arrays — related
- Children show greater inferior frontal gyrus activity than adults during numerical comparisons, while adults show greater left superior parietal activity than children — 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
