The linear effect of task difficulty on cognitive strategy use is competitively mediated by learner resources: difficulty decreases resources, which lowers strategy use, while a positive direct effect remains¶

q3 i? Available resources mediated a negative indirect linear effect of task difficulty on cognitive strategy use, competing with a positive direct effect (competitive mediation). → Seufert 2024

Seufert 2024¶

Seufert, T., Hamm, V., Vogt, A., & Riemer, V. (2024). The Interplay of Cognitive Load, Learners' Resources and Self-Regulation. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09890-1

q3 · i? · associational · r2

Mediation analysis (Sobel test) in the hierarchical models of the 67-student within-subject study: higher difficulty reduced the aggregated resource scale (prior knowledge, interest, self-efficacy, etc.), which lowered cognitive strategy use; the article names this a competitive mediation.

"we revealed a significant indirect linear effect of perceived task difficulty on cognitive strategy use, mediated by available resources (a × b = -0.18, z =—4.90, SE = 0.04, p < 0.001; see Table 3). With increasing perceived task difficulty, fewer resources were available, which resulted in lower cognitive strategy use."

Discussion¶

Learner Variables¶

• Self-Regulation — outcome: instruction changes it

• For metacognitive strategy use, resources competitively mediate the linear effect and cognitive load partially mediates the linear and mediates the quadratic relationship — related
• Task difficulty shows an inverted U-shaped relation with cognitive strategy use and a positive linear relation with metacognitive strategy use, mediated by cognitive load (Seufert et al., 2024) — related
• Perceived task difficulty relates to cognitive strategy use with both a linear and a negative quadratic (inverted U) component, and the quadratic relationship is fully mediated by cognitive load — related
• Task difficulty shows a u-shaped relation to regulatory activities, with competing CLT-based and motivational explanations that cannot yet be distinguished — related
