Document Summary
Sensation & perception are the underlying processes operating in visual illusion. Illusion: the way you perceive the stimulus doesn"t match its physical reality. Sensation: detection of physical energy by our sense organs (eyes, ears, skin, nose, & tongue) which relay information to the brain. Perception: brain"s interpretation of these raw sensory inputs. Sensation allows us to pick up the signals in our environments & perception allows us to assemble these signals into something meaningful. Naive realism: assumption that our sensory systems are infallible & that our perceptions are perfect representations of the world around us. Filling-in: when our brains reconstruct the image/pattern w/o our awareness. We use available sensory information to make sense of what"s missing & thereby identify incomplete objects. 4. 1-4. 2: two sides of the coin: sensation and perception. Our brain picks & chooses among the types of sensory info it uses, relies on expectations and prior experiences to fill in the gaps & simplify processing.
