James Gibson

James J. Gibson (1904–1979) was an American psychologist who upended how we think about perception. Where others saw the mind as a computer processing inputs, Gibson saw an animal actively exploring its environment.
His key concept: affordances. An affordance is what an environment offers an animal — a surface affords walking, a handle affords grasping, a cliff affords falling. The affordance exists in the relationship between animal and environment, not in the object alone.
This ecological approach influenced design (through Donald Norman), robotics, and philosophy of mind. Perception isn’t passive reception; it’s skilled engagement with the world.
