Question

In order to get a good idea of an object's depth, we rely on a number of binocular and monocular cues. Which of the following would be an example of a binocular cue?

a. Retinal disparity
b. Convergence
c. Interposition
d. Binocular rivalry

Answer 1

Binocular cues, which rely on both eyes for the perception of depth, include retinal disparity and convergence. Retinal disparity involves the brain interpreting the slight differences between the images each eye sees, while convergence relates to the inward turning of the eyes when focusing on closer objects.

Step-by-step explanation:

To understand the depth of objects, our brain employs various cues that are divided into binocular and monocular cues. Binocular cues are those that require the use of both eyes to perceive depth. The binocular cues include retinal disparity and convergence. Retinal disparity refers to the slight difference in the view that each eye receives due to their separate positions on the face. Each eye captures a slightly different image, and the brain uses the discrepancy between these two images to gauge the distance and depth of objects.

Convergence is another binocular cue where the eyes physically turn inward as they focus on closer objects, which provides the brain with information on the object's depth. On the other hand, interposition and binocular rivalry are not examples of binocular depth cues. Interposition is a monocular cue that involves one object overlapping another, indicating that the overlapping object is closer.
