Within contemporary developmental science, models derived from relational developmental systems metatheory emphasize that the basic process involved in the ontogeny of civic engagement involves mutually-influential and beneficial relations between the developing individual and his or her complex and changing social, cultural, and physical contexts (represented as individual ← → context relations). The authors suggest that research on the development of civic engagement should be theoretically predicated, use change-sensitive, longitudinal methods, and be comparative across time and place. Using these facets of scholarship as a lens, we discuss the contributions to this special issue. We conclude that the present set of studies provides a useful basis for future research and applications aimed at understanding and promoting individuals’ civic contributions, and their support of social organizations promoting individual thriving and freedom, liberty, and social justice.
