Note. In each case, latent constructs corresponding to cognitive abilities (portrayed as circles) are defined by observed variables (portrayed as squares), and they are used as simultaneous predictors of the target variable (portrayed as a square). In addition, age variation in the reference abilities and the target variable is controlled by specifying relations of age to the ability constructs and to the target variable. The latent variables are correlated with one another on the model on the left, and all observed variables are related to a common factor on the model on the right.
