Gibson direct. Theory of perception

    Cards (7)

    • how does this theory contrast with Gregory's?

      perception doesn't draw on past experience
    • Sufficient information for direct perception
      Sensation and perception are the same. The eyes detect everything we need without having to make inferences.
    • Optic flow patterns
      When moving, things in the distance appear stationary and everything else rushes past. Provides perceptual information about speed and distance.
    • motion parallax
      a monocular depth cue
      when we are moving past them, closer objects appear to move faster than objects that are further away
      provides perceptual information about speed and distance
    • the influence of nature
      Perception is inborn not learned
    • strengths (2)

      real world meaning
      - research was on WW2 pilots, so relevant to daily life
      support for the role of nature
      - Gibson and walk showed few infants crawl off a visual cliff, so are born with depth perception
    • weakness
      theory struggles to explain visual illusions
      - perception is seen as accurate but illusions trick the brain, so theory is incomplete
