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 strong group x condition x timepoint interaction in DLPFC reflected children's late REL-1 activation and adults' larger early REL-2 peak. → Crone Eveline A. 2009

q3 · i? · associational · r2
ROI timecourse analysis of left DLPFC in the same participants. The interaction "F (16, 480) = 2.62, p < .005" was driven by an increased peak activation in adults relative to children for the REL-2 condition (F(1,30) = 5.20, p < .05); children showed sustained DLPFC for REL-1.
"Within DLPFC, a strong group x condition x timepoint interaction was evident, F (16, 480) = 2.62, p < .005. Here again, children but not adults demonstrated increased BOLD signal linked to the solution of REL-1 problems during the latter portion of the timeseries."
Discussion¶
Related Claims¶
- 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
- 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 — a broader claim this one bears on
- 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 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 and adults do not differ in response times on REL-2 problems, despite children's higher error rate on those trials — related
- Among children, right RLPFC activation for relational integration increases with age, with no relationship to estimated IQ — related
