The study analyses the dimensionality of executive functions (EF) and its relationship with behavior in typically developing 3- and 4-year-old children. In study 1, confirmatory factor analysis (CFA) was used to investigate the validity of a one-factor model in 117 preschoolers. Since this model was not confirmed, a two-factor model was identified through exploratory factor analysis. In study 2, the validity of the new two-factor versus one-factor model was tested on a new sample of 128 children through a series of CFAs. The relationship between the models and specific behavioral aspects of the children was investigated. The results suggest that a bidimensional structure showed a better fit to the data and more ecological validity than a unitary structure.
