Definition: Information taken in by both eyes that aids in depth perception, including binocular convergence and retinal disparity.


Psychologists Eleanor Gibson, and Richard Walk created a "visual cliff" experiment to test on infants.
Psychologist Bower also tested infants only two weeks old by putting on 3-D glasses and produced "virtual reality" pictures.

Quite Simply...

  • Binocular cues help you judge how far things are due to the fact that you have 2 eyes.
  • Information processed into both eyes. Both of your eyes help strengthen your perception in depth.
  • How you see the world as one image using two eyes.

Examples of Binocular Cues

  • Hold one of your fingers about a foot away from your eyes. Now close one eye and look at your finger. Alternate between which eye is kept open/closed. You will notice that your view on your finger will change depending upon which eye is looking at your finger.
  • Hold one finger about six inches from your eyes, and look at it. Then move it a foot farther and you can feel the change in eye muscles at different distances.

  • Binocular Convergence, which suggests how the lines of vision from each eye converge at different angles on objects at different differences.
  • Retinal Disparity, which is the different perspectives of each separate eye.
  • Monocular Cues, which is depth perception in only one eye.
