    • what did Gibson state
      -sensation and perception are the same thing.
      -everything in our visual field gives us all the information we need to judge distance depth and movement.
      -we are born with perception (nuture)
    • optic flow of patterns
      when we are moving towards a fixed point it stays stationary whilst the rest of the view seems rushed. if our brain does see this optic flow it fails to realise we are moving
    • motion parallax
      when we are moving objects that are closer to us in our visual field appear to be moving faster than those father away from us
    • influence of nature
      we do not need to learn how to perceive the world around us as its innate.
      the eye can detect fine changes in light, texture, movement and depth without need for past experience. this is why the baby wouldn’t fall off the edge of a cliff we are born with perception
    • what is a strength(Gibson)
      one strength is that research provides good support for gibsons theory. The visual cliff experiment shows that we do not need to learn how to perceive the world around us as they did not crawl off of the edge. This is a strength because it shows we do not always need past experiences to perceive the world around us. this supports gibsons idea that perception is innate
    • what is a weakness(Gibson)
      perceptual errors are not easily explained by gibsons theory. visual illusions are good examples of when our brain makes perceptual errors and draws wrong conclusions about what we are looking at. this is a weakness because gibson said their is no need for processing the information we receive about size shape and distance yet evidenve from illusions show that sensation and perception are separate processes therefore gibsons theory is limited as it cannot explain this
