q3 i? A whole-brain regression of the REL-2>REL-1 contrast in children revealed a strong positive relationship between age and right RLPFC activation, but no significant effect of KBIT-2 score. → Crone Eveline A. 2009

q3 · i? · associational · r2

Whole-brain multiple regression including age and estimated IQ as covariates, run on the REL-2>REL-1 contrast in the child group only. The article reports "a strong positive relationship (at p<.001) between age and right RLPFC activation"; no effect size was printed.

"This analysis revealed a strong positive relationship (at p<.001) between age and right RLPFC activation (Figure 5b). There was no significant effect of KBIT-2 score on brain activation."

Discussion¶

Related Claims¶

• 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
• 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
• 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
