Document Summary
The real thing in the real world you"re trying to perceive. Proximal stimulus is 2d but we perceive it as 3d. Our perception of an object"s features remains constant even when viewpoint (and proximal stimulus) changes. Perception of size doesn"t change with distance. Perception of color doesn"t change with light. Perception of shape doesn"t change with angle. Ask not what"s inside your head but what your head is inside. Our perceptual system knows how to extract the direct information. Environment provides all the cues you need to accurately see what is out there. Our brains are pre-wired to pick up cues. Perception uses dte from the world and our prior knowledge and expectations. Together these are put together to construct a precept. Comes from world matter, but your mind can influence what you. Driven by whats out there in the world. Direct perception claims perception is purely bottom-up. Perception is composed entirely of bottom up.
