Explain how our experience helps us interpret the world around us: describe perceptual constancies, and why they are useful, compare the structuralist, gestalt, and constructivist (knowledge-based) approaches to perception. Info from outside body (collected by nervous system) is converted to electrical impulses sent along (cid:374)er(cid:448)es to the (cid:271)rai(cid:374) (cid:449)here it"s i(cid:374)terpreted a(cid:374)d a(cid:272)ted upo(cid:374) Sensation: process by which our sensory system gather info about environment; turns chemical, mechanical, sound and light energy in world into electrical signals in the brain ie. light pressure on skin, pattern of vibration in air. Perception: selection, organization, and interpretation of sensations as meaningful objects & events; extracting meaning from what is sensed, tying to what we know and understand ie. a loving touch, music.
