The Bioecological Model
Bronfenbrenner's mature framework specifying that human development is a joint function of four interacting elements—proximal process, person characteristics, nested environmental contexts, and historical time—making every single-variable account of how minds develop structurally incomplete.
The bioecological model—the mature form of
Urie Bronfenbrenner's ecological systems theory, formulated with Pamela Morris in 2006—specifies that developmental outcomes are a joint function of four elements whose interaction no single factor can predict. The
process is the proximal process, the engine of development: the progressively complex, reciprocal interaction between the developing person and the persons, objects, and symbols in her immediate environment. The
person brings her own characteristics—biological dispositions, prior developmental history, the cumulative effect of her particular nested environments. The
context is the full nested architecture of microsystem, mesosystem, exosystem, and macrosystem within which the process occurs. The
time is the chronosystem—the historical moment, whose specific features shape the character of every other element. The PPCT model predicts, with unusual precision, what
