q2 i? Only children (6-12 years) produced a reliable positive math achievement effect in the IPS bilaterally and extensive right parietal cortex; adolescents and adults showed no reliable parietal link except a left precuneus effect in adults. → Haist Frank 2015

Evidence¶

Haist Frank 2015¶

Haist Frank, Wazny Jarnet H., Toomarian Elizabeth, Adamo Maha. (2015). Development of brain systems for nonsymbolic numerosity and the relationship to formal math academic achievement. Human brain mapping. https://doi.org/10.1002/hbm.22666

q2 · i? · associational · r2

Separate whole-brain regression analyses per age group (children, adolescents, adults) with age, FSIQ, and Letter-Word ID as covariates, using achievement data from 43 participants. The finding that "only children produced a reliable positive math achievement effect in the IPS bilaterally" drives the full-sample parietal result.

"The striking finding was that only children produced a reliable positive math achievement effect in the IPS bilaterally. Children, but not adults or adolescents, produced extensive right parietal activity in addition to the IPS, including the regions of the SPL (BA 7), and the IPL including SMG (BA 40)."

Discussion¶

Related Claims¶

• Behavioral nonsymbolic numerosity acuity (RT and accuracy ratio effects) does not reliably predict formal math achievement in typical to high-achieving participants aged 6 to 34 — related
• Neural ratio sensitivity in parietal cortex, including bilateral IPS, increases with development from childhood into adulthood — related
• In adults only, poorer math achievement is associated with greater hippocampal NRE sensitivity — related
• Math achievement correlates with ventral occipital-temporal NRE in both children and adults, with children relying on extrastriate and adults on anterior higher-order visual regions — related
• A graded left superior parietal retrieval-success effect emerges by age 12 but is absent in 8-year-olds — 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
