A validated nine-task battery developed by Guo et al. for assessing tool innovation, strategic flexibility, and problem solving in children aged 3–6.

Components

Claims

• 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% [+M]
• Single latent factor models fitted both task success and ideal manipulation well, suggesting robust internal consistency, though Cling-subtract loaded weakly on task success [+M]
