• visual perception is the ability to organise and interpret ones environment
• bottom up processing involves using sensory information to perceive the world around us rather than relying on prior knowledge
• top down processing is a process that uses exisiting knowlegde to interept new information
• optic aray is the pattern of light and visual information that is reflected from the enviroemnt and projecetd onto the retina of the eye this si what gibson argued
• it encompasses all the visual stimuli at at that particular moment
• Gibson argued that perception is based on inetrcations with the world and not the mental reprsentation
• invariant information is an aspect of visual stimuli that remaisn constant and unchanged despite movement providing cues for the obesvere allowing interpertation
• like linear lines that are parallel that appears to converge as they reced in distance
