Figure 3.
Correlations between the genetic (A), shared environmental (C), and nonshared environmental (E) variance components on Common EF and WM-Specific in midlife, and general cognitive ability in midlife (Panel A) or young adulthood (Panel B). Common EF and WM-Specific are not correlated, by definition. Circles and ellipses represent latent variables, and rectangles represent measured variables. Factor loadings and residual variance components for the individual EF tasks are not displayed here, but were nearly identical to those displayed in Figure 2. Significant factor loadings and correlations are displayed with black text and black lines (p < .05).
