Depth and size

View mindmap
  • Depth and size
    • Size constancy - we perceive an object as the same size even when its distance from us changes.
      • When an object is close, our brain scales it down in size so that it looks normal rather than enormous.
      • When an object is far away, it is scaled up so that it looks its normal size rather than tiny. (size constancy)
    • Think d-u-b: DISTANT things are scaled UP to make them seem BIGGER than the image on the retina.
      • Think ne-d-s: NEARBY things are scaled DOWN to make them seem SMALLER than the image on the retina.
