The model optimization process demonstrates significant improvement in fit through three added paths (Δχ2 = 38.72*). The final model shows excellent fit indices (CFI = 0.92, RMSEA = 0.04, SRMR = 0.03). Path analysis reveals a strengthened “culture-space” association (0.65→0.71*) and a notable “presence-emotion” effect (B = 0.54). Bootstrap validation with 5000 resamples confirms model stability, as key paths’ confidence intervals exclude zero.
