Figure 4.

The best-fitting latent factor model for working memory tasks and across list lengths within digit and reading span tasks. (A) Parameters are depicted as in Figure 3, although arrows depicting the contribution of each latent factor, η, to accuracy on each task, λ, are omitted for clarity. Model parameters λ that had a Bayes Factor greater than 3:1 in favor of lying outside of the region of practical equivalence (see text for details) are in bold, parameters with Bayes Factors between 3:1 and 1:1 are shown in black, and parameters with Bayes Factors less than 1:1 are shown in gray. (B) The two latent working memory factors differ across individuals and are not correlated across the group. Most likely values of each latent factor for each participant are depicted as circles, and shaded gradients around each most likely value depict the corresponding probability density for that participant.
