Three simplified models showing executive function (EF) development. Model (a) includes a latent construct of attention that influences baseline levels (EF intercept) and rate of growth of EF (EF slope). Model (b) shows a latent construct of language mediating baseline EF and its developmental trajectory. Model (c) includes latent constructs of attention and language, which both influence the development of EF. These models could be tested using latent growth curve modelling.
