Theoretical and Applied Dynamic Systems Research in Developmental Science

This article discusses some of the ways in which dynamic systems approaches have been applied to developmental science. Dynamic systems thinking suggests that (a) there is always change within stability at the level of real-time (microscopic) behavior, and (b) microlevel change provides the seeds for developmental (macroscopic) change. It is only possible to study these propositions using microgenetic designs, case-based studies of change using frequent observations across development. Normal parent–infant relationships smooth out otherwise abrupt developmental transitions using a bridging process. The absence of developmental bridging may reflect problematic or even traumatic growth patterns, suggesting that bridging, a feature of a developmental trajectory, may serve as a diagnostic individual differences variable.
