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? In a DRM-paradigm fMRI study, graded activation in left superior parietal cortex (BA 7) during retrieval was observed among 12-year-olds and adults but not among 8-year-olds. → Ghetti Simona; Bunge Silvia A 2012

q2 · i? · review · r3
Developmental fMRI study using the Deese-Roediger-McDermott paradigm (Paz-Alonso et al., 2008, as reviewed) comparing 8-year-olds, 12-year-olds, and adults. The authors interpret the absence in 8-year-olds as consistent with increasing specialization of episodic-retrieval regions during childhood.
"we showed a retrieval success effect with a pattern of graded activation in left superior parietal cortex (BA 7) among 12-year olds and adults, but not among 8-year-olds."
Discussion¶
Related Claims¶
- Earlier studies suggested mature active-learning patterns emerge only in late childhood, but the article attributes this to paradigm limitations — related
- Inferior parietal cortex (BA 39 and 40) shows greater overall activation in adults than children and a more pronounced effect of relational integration in adults — related
- FIR analysis shows adults sustain DLPFC, RLPFC and superior parietal activation for relational integration through later time-bins, whereas children's integration-specific activation appears only in the first time-bins and late DLPFC activation is tied to REL-1 — related
- A reliable positive relationship between parietal NRE and math achievement appears only in children, not adolescents or adults — related
- Children show greater inferior frontal gyrus activity than adults during numerical comparisons, while adults show greater left superior parietal activity than children — 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
