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? The age-group difference in accuracy was more pronounced for REL-2 than for REL-1 trials, while the REL-1 vs REL-0 difference showed no age interaction. → Crone Eveline A. 2009

q3 · i? · associational · r1
Behavioral accuracy analysis during fMRI scanning in 15 children (8-12) and 17 adults (18-25) performing an RPM-like task. The Age Group x Relational complexity ANOVA showed the age difference in accuracy was "more pronounced for REL-2 than for REL-1 trials (F (1, 29) = 10.59, p < .001)". No effect size printed.
"the differences in accuracy across age groups were more pronounced for REL-2 than for REL-1 trials (F (1, 29) = 10.59, p < .001), but not for REL-1 than for REL-0 trials (F < 1)."
Discussion¶
Related Claims¶
- Children and adults do not differ in response times on REL-2 problems, despite children's higher error rate on those trials — related
- Adults show sustained RLPFC activation for REL-2 problems, whereas children's early RLPFC differentiation of REL-2 from REL-1 is not sustained across the trial — 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
- Children show initially reduced DLPFC activation relative to adults for REL-1 and REL-2 trials, but sustained DLPFC activation for REL-1 problems in the later trial phase — related
- Adults show greater left inferior lateral PFC activation than adolescents during relational integration — 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
- Relational integration is less accurate and slower than single-relation matching regardless of audience or age — a broader claim this one bears on
