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? For grades 1-2 the reward-based family showed greater relative support, whereas for grades 4-5 and 7-9 the belief-based family received greater relative support. → Zhang 2026

q2 · i? · causal · r2
LOO-based model-family comparison in Study 2: reward-based M1-3 fit best in grades 1-2 (LOOIC = 4520.28), belief-based M2-3 in grades 4-5 (LOOIC = 4604.05) and grades 7-9 (LOOIC = 5223.59), with mixed, non-decisive support in grades 10-12.
"Overall, these results suggest that younger scho ol-age children were more consistent with reward -based updating, whereas from grades 4 -5 onward there was increasing relative support for models that track opponent-specific behavioral regularities."
Discussion¶
Related Claims¶
- Preschoolers' Chicken game choices are best explained by reward-based learning with a higher learning rate for the competitive opponent — related
- Review reports a developmental shift in cognitive offloading: children under-use external aids while adolescents over-rely on them — related
- Preschoolers gradually learn to cooperate more with high-competitive than low-competitive opponents in the Chicken game — related
- School-age children and adolescents distinguish competitive from cooperative opponents, with cooperation peaking in late childhood — related
- Children's reinforcement learning is best fit by a one-learning-rate model, whereas adolescents and adults are best fit by Bayesian models incorporating hidden-agent beliefs — a narrower finding that bears on this claim
