1. How do disparity-selective cells operate?

  • The seperation between the receptive field centers (relative to the fovea of each eye) of binocular cells in each eye defines the V1 cells preferred disparity
  • The disparity between the receptive field centers (relative to the fovea of each eye) of binocular cells in each eye defines the V5 cells preferred disparity

2. If I closed my left eye, and the target was closer than my fixation point, which diplopic image would disappear?

  • Both images
  • Right image
  • Neither image
  • Left image

3. What is linear perspective?

  • When items further away from the individual are smaller than those closer
  • When items further away from the individual are larger than those closer
  • When the texture of the item indicates depth
  • When items closer to the viewer occlude those further behind

4. How does convergence work?

  • The perception of depth can be increased by artificially creating shadow and a longer optical path to edges
  • How much your eyes need to move to focus on an object (objects closer will need more movement than those further away)
  • 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 ability to stretch and relax the lens, the degree of strain is translated into the distance of the object

5. If I was looking at two objects 1 metre away, what is the minimum distance I can tell which is closer to me?

  • 30mm
  • 5mm
  • 1mm
