q2 i? Whole-brain regression of AU-score on the AU > OC contrast found significant correlations in left lateral PFC (MFG and IFG pars triangularis) at an uncorrected threshold. → 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

q2 · i? · associational · r1

Whole-brain regression analysis with AU-score as covariate of interest on the AU > OC contrast. No regions survived FDR correction; at the lowered threshold p < 0.001 uncorrected, correlations appeared in left lateral PFC. The study notes this threshold was applied "to overcome the relatively low power inherent to analyses of individual differences."

"activation levels for the contrast AU > OC were correlated with creative performances in a region in the left lateral PFC (MFG and IFG pars T riangularis, seeFigures 4A,B)"

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
• AU and OC conditions show distinct correlation patterns with external creativity and fluency measures, supporting their differentiation as divergent thinking versus verbal ability conditions — related
• Generating multiple alternative uses (AU2+ > OC2+) additionally recruits left inferior frontal gyrus and middle frontal gyrus beyond the temporo-parietal network — 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 — related
• More solutions are generated in the OC condition than the AU condition, and adults generate more answers than adolescents in general, with no condition-specific age difference — related
• Adults show greater left inferior lateral PFC activation than adolescents during relational integration — related
• Ideation-based interventions are a robustly implemented explicit approach that improves creative performance — related
