Abstract:
The goals of this article are to (a) describe and contrast conceptual characteristics of periods of developmental sensitivity, disturbance, and stasis, and (b) translate these concepts to testable analytic models with an example dataset. Although the concept of developmental sensitivity is widely known, the concepts of developmental stasis and disturbance have received less attention. We first define the concepts and their principles and then, using repeated measures data on impulsivity and alcohol use from adolescence to young adulthood, propose the dual latent change score (LCS) growth model as one analytic approach for evaluating evidence for key characteristics of these developmental concepts via examination of intraindividual time-varying associations.
