Susan Oyama is a psychologist and philosopher of science, currently professor emerita at the John Jay College and CUNY Graduate Center in New York.
Oyama's work interrogates the Nature versus nurture debates, and problematizes the conceptual foundations (e.g., assumptions, binaries, and classifications) on which these debates depend. Her notion of a "developmental system" allows us to reevaluate and reintegrate standard dichotomies such as development and evolution, body and mind, object and subject, and stasis and change. Oyama's Developmental systems theory has had a significant impact in philosophy of biology, cognitive science, and psychology.
