Latent structure of executive function in five- and six-year-old children: A longitudinal study

Abstract

This longitudinal study analyses the structure of executive function in children assessed at five and six years of age and examines the longitudinal relationships between the executive function dimensions identified at the two age levels. Confirmatory factor analysis was used to examine the latent structure of executive function at both age levels. The best fit to the data at both age levels was a two-factor model in which inhibition was distinguished, while working memory and shifting emerged as a unitary component. Some variables show a moderate longitudinal stability and the inhibitory control tasks display reduced continuity across ages.
