q3 i? Contrasting trials with two or more AU against trials with two or more OC revealed additional activation in left MFG and left IFG pars triangularis. → Kleibeuker 2013

Evidence¶

Kleibeuker 2013¶

Kleibeuker, S. W., Koolschijn, P. C. M. P., Jolles, D. D., De Dreu, C. K. W., and Crone, E. A. (2013). The neural coding of creative idea generation across adolescence and early adulthood. Frontiers in Human Neuroscience 7:905. https://doi.org/10.3389/fnhum.2013.00905

q3 · i? · causal · r2

Second fMRI analysis contrasting trials on which participants generated two or more AU with trials generating two or more OC (AU2+ > OC2+), FDR corrected. The study reports "additional activation" in left MFG and left IFG pars triangularis beyond the temporo-parietal regions. No effect size printed.

"However, additional activation was observed in several regions, including left middle frontal gyrus (MFG) and left inferior frontal gyrus (IFG) pars T riangularis (see Ta b l e 5)."

Discussion¶

Related Claims¶

• Adults show larger left IFG/MFG condition effects (AU relative to baseline) than adolescents, indicating adolescents do not yet recruit left lateral PFC at an adult level for creative thinking — related
• Divergent thinking performance (AU-score) positively correlates with left IFG/MFG activation for AU relative to OC trials — related
• Generating alternative uses relative to ordinary characteristics recruits mainly left temporo-parietal regions (left SMG, left AG, bilateral MTG) in both adolescents and adults — a broader claim this one bears on
• Adults show greater left inferior lateral PFC activation than adolescents during relational integration — related
