Direct Perception and Invariance

Gibson challenges the conventional view of perception by proposing the concept of direct perception, where individuals can directly perceive information from the environment without relying on internal cognitive processing. He introduces the idea of invariance to explain how certain properties of the ambient optic array remain constant across changes in viewing conditions, allowing for accurate perception. By focusing on higher-order invariants like structural and transformational invariance, Gibson emphasizes the importance of ecological context in understanding behavior.
