q3 i? The flexibility-by-difficulty interaction was significant for ideal manipulation but not for task success, with flexibility's facilitating effect more salient for higher-difficulty tasks. → Guo 2025

q3 · i? · design · r2

In the ideal-manipulation multilevel logistic regressions, the difficulty-by-flexibility interaction was significant, whereas the same interaction was not significant in the task-success analyses — a scope limit across outcome measures.

"However, in this line of analyses, the interaction effect of difficulty level with flexibility was significant (while it was not significant for task success). This implies that the facilitating effect of behavioral flexibility on ideal manipulation was more salient for tasks with a higher difficulty level."

Discussion¶

Learner Variables¶

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