Figure 4. Regression model of verbal fluency and other cognitive latent factors at age 56.

Structural equation model where both fluency factors are regressed on latent variables for executive function (common executive function, working memory–specific), vocabulary, and episodic memory. Not pictured are factor loadings on latent factors (which are similar to our previous work and those displayed in figure 2). Significant paths and correlations are displayed with black text and lines (p < 0.05).
