q3 i3 Children showed significant brain-behavior correlations in right OTC (r = .53), left superior parietal cortex (r = .49), and IFG bilaterally (right r = .73; left r = .47). → Cantlon Jessica F. 2009

q3 · i3 · associational · r1

Correlational analysis relating each child's behavioral ratio effect (accuracy on 0.5 minus 0.8 ratio trials) to their BOLD ratio effect. For adults, "the ratio effect in BOLD signal did not correlate with individual differences in performance in any region (all ps > .05)."

"Children, in contrast, showed a significant correlation between the behavioral and BOLD ratio effects in three regions: right OTC (r = .53, p < .05), left superior parietal cortex (r = .49, p < .05), and the IFG bilaterally (right: r = .73, p < .01; left = .47, p < .05)."

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
• 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
• Children show greater inferior frontal gyrus activity than adults during numerical comparisons, while adults show greater left superior parietal activity than children — related
• Neural ratio sensitivity in parietal cortex, including bilateral IPS, increases with development from childhood into adulthood — related
• A reliable positive relationship between parietal NRE and math achievement appears only in children, not adolescents or adults — 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
