Decomposition of cognitive load mediation effects (Bootstrap method, 5,000 samples).
| Effect Type | Estimate | 95% CI | p-value | Proportion (%) |
|---|---|---|---|---|
| Total Effect | 0.63 | [0.51, 0.75] | 0.001 | 100.0 |
| Direct Effect | 0.33 | [0.18, 0.48] | 0.006 | 52.4 |
| Mediation Effect | 0.30 | [0.22, 0.38] | 0.009 | 47.6 |
Standardized effects estimates; total effects model R² = 0.76; mediator share = indirect effects/total effects × 100%; Bootstrap confidence intervals are bias-corrected; *p < 0.05, **p < 0.01, ***p < 0.001.
