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? Cross-sectional hippocampal ROI engagement was higher in children at Time-2 than in adolescents and adults, with no adolescent-adult difference. → Qin Shaozheng 2014
Evidence¶

Qin Shaozheng, Cho Soohyun, Chen Tianwen, Rosenberg-Lee Miriam, Geary David C., Menon Vinod. (2014). Hippocampal-neocortical functional reorganization underlies children's cognitive development. Nature Neuroscience. https://doi.org/10.1038/nn.3788
q3 · i? · associational · r2
Cross-sectional fMRI ROI analysis across children at Time 2, adolescents, and adults (total 68 participants) showed a main effect of group in the hippocampus; the article also reports no differences between adolescents and adults (P=0.87). No effect size is printed.
"A follow-up ROI analysis confirmed a main effect of group (F(2,65)=8.61, P<0.001), with larger hippocampal engagement for children at Time-2 compared to adolescents and adults (Scheffe's Ps<0.009)."
Discussion¶
Related Claims¶
- The anterior hippocampus becomes functionally specialized for episodic memory around the transition to adolescence — related
- Inter-problem multivoxel pattern stability in the hippocampus increases from childhood through adolescence into adulthood, reaching adult-like levels by adolescence — related
- Memory-based strategy use continues to increase from childhood through adolescence into adulthood — related
- Hippocampal engagement during arithmetic problem solving increases longitudinally in children while prefrontal-parietal engagement decreases — related
- In the one longitudinal fMRI study, dorsolateral prefrontal engagement reached adult levels by adolescence while dorsal anterior cingulate engagement continued increasing and mediated behavioral improvement — related
- Meaningful engagement with AI as a co-regulatory partner is more likely from middle childhood onwards — a broader claim this one bears on
- Episodic memory improves during middle childhood while familiarity-based recognition reaches adult levels by age 8 — related
- Hippocampal volume relates to episodic memory differently across development: adults show head/body associations, children show tail associations — related
- In adults only, poorer math achievement is associated with greater hippocampal NRE sensitivity — related
