Jeff Salzman of The Daily Evolver recently spoke with Terri O’Fallon of Pacific Integral about her STAGES model of adult development, and to Kim Barta, a master psychotherapist who uses Terri’s research in his work. The model has been statistically grounded to correlate with the Sentence Completion Test as advanced by Susanne Cook Greuter which is the most widely-used and researched test of adult human development. STAGES validates three new, later stages of development; it is the first integrally based developmental model, incorporating quadrants, states, lines and types. As such, StAGES provides statistical support for Ken Wilber’s integral theory. It reveals a natural sequence of deep “vertical” structures, as well as iterating, wave-like patterns of development.
