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? A significant group x condition x timepoint interaction in RLPFC was driven by late-trial differences: adults maintained higher BOLD for REL-2 throughout, children showed increased signal for REL-1 in the later phase. → Crone Eveline A. 2009

q3 · i? · causal · r2
ROI timecourse analysis of left RLPFC in 15 children and 17 adults during the RPM-like task. Both groups showed early REL-2 vs REL-1 differentiation (4-8 s), but "adults demonstrated a consistently higher level of BOLD signal for REL-2 throughout the period of measurement, children demonstrated increased signal for REL-1 during the later phase".
"Within RLPFC, a significant group x condition x timepoint interaction was observed, F (16, 480) = 1.96, p < .05. Post hoc comparisons revealed that this interaction was driven by differences during the latter part of the timeseries"
Discussion¶
Related Claims¶
- Children aged 8-12 are disproportionately less accurate than adults on REL-2 problems requiring integration of two relations, but not on REL-1 or REL-0 problems — 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
- 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 — possibly the same claim (merge candidate)
- Children and adults do not differ in response times on REL-2 problems, despite children's higher error rate on those trials — 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
- Among children, right RLPFC activation for relational integration increases with age, with no relationship to estimated IQ — related
- Adults show greater left inferior lateral PFC activation than adolescents during relational integration — related
