2. How do random dot stereograms show how stereopsis works re; binocular disparity?

  • The edges are found, the disparity is calculated and the depth is determined
  • Disparity and depth precede edge extraction in RDS. Because some dots are shifted laterally with respect to others, these dots in the displaced square do not fall on corresponding points on both eyes --> they have disparity
  • Edge extraction precedes disparity and depth in RDS. Because some dots are shifted laterally with respect to others, these dots in the displaced square do not fall on corresponding points on both eyes --> they have disparity

3. How do autostereograms demonstrate disparity-selectivity?

  • The picture appears superimposed with itself with an offset, the cells find matches in nearby repeated patterns. To view the image as 3D, eyes must converge at a diff plane of depth to the picture.
  • The two images are adjacent, the cells find matches in nearby repeated patterns. To view the image as 3D, eyes must converge at a diff plane of depth to the picture.

4. What is accomodation?

  • The ability to stretch and relax the lens, the degree of strain is translated into the distance of the object
  • The ability to relax the lens, the degree of strain is translated into the distance of the object
  • The ability to stretch and relax the lens, the distance of the object is translated into degree of strain
  • The ability to stretch the lens, the degree of strain is translated into the distance of the object

5. How does convergence work?

  • How much your eyes need to move to focus on an object (objects closer will need more movement than those further away)
  • The ability to stretch and relax the lens, the degree of strain is translated into the distance of the object
  • A MONOCULAR depth cue in which we view objects that are closer to us as moving faster than objects that are further away from us
  • The perception of depth can be increased by artificially creating shadow and a longer optical path to edges
