What is the main reason for binocular disparity?

  • The lateral separation of the eyes, which results in slightly different image inputs for each eye (correct)
  • The difference in the angle of stimuli on the retina between the two eyes
  • The difference in the size of the retinal images between the two eyes
  • The vergence movement of the eyes, which helps to keep an object at fixation
  • What is the name of the region where objects can fall and produce no disparity?

  • The horopter (correct)
  • Vergence circle
  • Stereoscope
  • Fixation plane
  • What is the relationship between perceived size and perceived distance?

  • Perceived size is proportional to the square of perceived distance
  • Perceived size is inversely proportional to perceived distance
  • Perceived size is independent of perceived distance
  • Perceived size is directly proportional to perceived distance (correct)
  • What is the purpose of the vergence movement of the eyes?
