In this presentation I discuss structural equation modeling as a framework for examining developmental processes. First, I present some principles of longitudinal research that underlie both study designs and statistical models for longitudinal data. I then describe models that focus on mechanisms of within-person change, and demonstrate their use for examining developmental processes. I illustrate the use of these models with empirical data of fluid reasoning from childhood to adolescence. In a set of analyses, I investigate: a) the definition of a fluid reasoning factor using four measures taken at up to three time points, b) invariance in the fluid reasoning factor across the three measurement occasions, and c) the developmental changes in fluid reasoning from childhood to adolescence as well as the contribution of brain maturation to such changes.
