module 19

Clues about distance that are based on the image from one eye are called

• binocular depth cues.

• monocular depth cues.

• subliminal stimulation.

• closure.

Clues about distance that require two eyes are called

• monocular depth cues.

• place theory.

• binocular depth cues.

• proximity.

This is an example of which type of monocular depth cue?

• texture gradient

• linear perspective

• interposition

• motion parallax

We rely on binocular vision to

• perceive depth

• see colors

• understand optical illusions

• see motion

Answer explanation

Remember that you can see depth with only one eye, but your depth perception will not be as good. ALSO, my eye doctor told me at my last visit that "some people are just not good at depth perception." Some people apparently meant me.

When the brain detects that the tension in the eye muscles is changing as the eyes turn inwards, this is called

• convergence.

• a monocular depth cue.

• accommodation.

• retinal disparity.

When the lens is automatically adjusted to look at objects far away or closer, this is called

• convergence.

• pictorial cues.

• retinal disparity.

• accommodation.

When we perceive more detail things are usually

• bigger.

• closer to us.

• further from us.

• more expensive.
