Subclaims¶

q3 i2 ROI analyses revealed significant gender × condition interaction effects for left SMG (η2 = 0.10) and left MTG (η2 = 0.14), with larger discrepancies for males relative to females. → 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 · i2 · causal · r1

Explorative whole-brain analyses showed no significant gender effects; ROI mixed ANOVAs on contrast estimates for four functional ROIs revealed "significant interaction effects" for gender × condition in left SMG (η2 = 0.10) and left MTG (η2 = 0.14), with larger discrepancies for males. No effects for lAG and lIFG/MFG.

"For lMTG and lSMG, significant interaction effects were observed for gender × condition (AU > OC) with larger discrepancies for males rela- tive to females [SMG: F(1, 41) = 4.88, p = 0.03, η2 = 0.10; MTG: F(1, 41) = 6.59, p = 0.01, η2 = 0.14]."

• 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 alternative uses relative to ordinary characteristics recruits mainly left temporo-parietal regions (left SMG, left AG, bilateral MTG) in both adolescents and adults — related
• Experimental groups differed significantly on prior VR experience and gender composition, which were used as covariates — related
