Which of the following are binocular depth cues? Select one.

Answer options:

Convergence

Height in plane

Linear perspective

Relative size

Retinal disparity

How to approach this question

The question asks for binocular depth cues. 'Bi' means two, and 'ocular' relates to the eyes. Therefore, you are looking for cues that require both eyes to work together. Review the list and identify which cues need two eyes. Convergence and retinal disparity are the two binocular cues. Select one of them.

Full Answer

A.Convergence✓ Correct

The correct answer is A. Convergence is a binocular depth cue. It refers to the way our eyes move inwards towards each other as we focus on a close object. The brain uses the degree of convergence to judge distance.

Depth perception allows us to see the world in three dimensions. We use both monocular (one eye) and binocular (two eyes) cues to do this. Binocular cues are particularly important for judging the distance of nearby objects. The two main binocular cues are convergence (the inward turning of the eyes) and retinal disparity (the slight difference in the image projected onto each retina). Options B, C, and D are all monocular cues.

Common mistakes

Confusing monocular and binocular cues. Forgetting that there are two binocular cues to choose from.
