Perception how we organize/interpret the world around us, attention, recognize the perceptual world. How body picks up signals and transforms it into a language we can understand. Sensations: messages from senses that provide link to environment. Process by which outside info is translated into neutral activity. Organization and interpretation of sensory information to create meaning. We like for things to make sense. Sensory and perceptual processes work together to make sense of what we are experiencing. Hard to distinguish between sensation and perception: process of interpreting sensation begins in sense organs and moves towards the brain. Sensation activation of sensory receptors by external physical stimulus energy; conversion of that energy into a neural impulse. Perception how brain organizes and interprets sensory information in a meaningful way. Taking in pieces of info and coming up with a conclusion. Top-down use expectations and knowledge of the world to understand info. Appling a pre-existing idea to understand pieces of info.
