Subclaims¶

q3 i? Age, general intelligence, and divergent thinking all significantly and positively predicted both task success and ideal manipulation. → Guo 2025 q3 i? No EF measure significantly predicted task success, but inhibition (positive) and cognitive flexibility (negative) significantly predicted ideal manipulation. → Guo 2025 (2)

Evidence¶

Guo 2025¶

Guo, J.; Bai, H.; Long, X.; Su, X.; Pang, W. (2025). The process of tool innovation in young children: An attempt to bridge the Gestalt and the perception-action theories. Learning and Instruction, 99, article 102182. https://doi.org/10.1016/j.learninstruc.2025.102182

q3 · i? · design · r2

Multiple linear regressions (N = 139) using CFA factor scores as outcomes; the authors report age, PPVT-R general intelligence, and TCAM divergent thinking were significant positive predictors of both performance measures.

"children's age and their measures of general intelligence and divergent thinking all significantly and positively predicted both children's task success and ideal manipulation."

q3 · i? · associational · r1

In the same regressions, Simon Says inhibition positively and DCCS cognitive flexibility negatively predicted ideal manipulation, while no EF measure predicted task success; the success–ideal manipulation factor correlation was 0.88 (p < 0.001).

"None of children's EF measures were a significant predictor of their task success; however, the EF measures of inhibition and cognitive flexibility were significant predictors of ideal manipulation, with positive and negative effects, respectively."

Discussion¶

Learner Variables¶

• Creativity — predictor: learners who differ on it differ in outcomes
• General Cognitive Ability — predictor: learners who differ on it differ in outcomes

• Single latent factor models fitted both task success and ideal manipulation well, suggesting robust internal consistency, though Cling-subtract loaded weakly on task success — related
• Task difficulty moderated the facilitating effect of flexibility on ideal manipulation only, with the effect more salient for harder tasks — related
• The nine new tool innovation tasks showed varied difficulty levels, with task success rates ranging from 33% to 94% and ideal manipulation rates from 24% to 91% — related
