ABSTRACT
In order for models to reflect the theory of developmental contextualism, multiple change processes or interactions should be considered: including individual changes, context/environmental changes, and the reciprocal relationships among individuals and/or their environments (see Ram & Nesselroade, 2007, for further elaboration). Or, as put by Wohlwill (1991), “. . . what [reciprocal relationships] would call for are methodologies that allow one to model the interpatterning between two sets of processes each of which is undergoing change, in part as a function of the other” (p. 128). In sum, the predominant theoretical perspective underlying the study of human development highlights the need for models that articulate how, when, and why dynamic entities interact.
