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? Whole-brain FIR analyses revealed markedly different activation dynamics over time in children compared with adults. → Crone Eveline A. 2009

q3 · i? · associational · r2
Finite impulse response whole-brain analysis in children and adults. In adults, integration-related increases in DLPFC, RLPFC and superior parietal cortex were "sustained over a longer duration, through the 8-12 second and 12-16 second time-bins"; children showed integration activation only early and late DLPFC for REL-1.
"For children, BOLD increases uniquely associated with relational integration were only seen in the initial two time-bins, and were most apparent in the first one (0-4 seconds post-stimulus). However, we observed late increases (between 8 and 16 seconds post-stimulus) in bilateral DLPFC, associated with 1st-order relational processing."
Discussion¶
Related Claims¶
- 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 — a narrower finding that bears on this claim
- 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 — possibly the same claim (merge candidate)
- Among children, right RLPFC activation for relational integration increases with age, with no relationship to estimated IQ — 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
- Meta-analyses identify a distributed frontoparietal network for flexible switching including vlPFC, dlPFC, ACC, right AI, parietal and subcortical regions — related
- A graded left superior parietal retrieval-success effect emerges by age 12 but is absent in 8-year-olds — 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
