Gestalt Principles and Depth Cues

Clues about distance based on the image of one eye.

• binocular depth cues
• monocular depth cues
• subliminal stimulation

Clues about distance requiring two eyes.

• monocular depth cues
• place theory
• binocular depth cues

Which of the following is not a monocular cue for depth?

• convergence
• texture gradient
• linear perspective
• shadowing

A binocular cue that allows for depth perception when images from the two eyes differ 

• Relative size 
• Color Constancy
• Linear perception
• Retinal Disparity

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

• Texture gradient

• Linear perspective

• interposition

• motion parallax

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

• convergence

• Monocular depth cue

• accommodation

• retinal disparity

Retinal disparity occurs because

• the eyes converge on a particular object and thus they look disparate

• the brain detects a change in the eye muscles

• each retina receives a slightly different visual image due to their distance apart

• we are all unique and different.

Which of the following is NOT a depth cue

• Convergence

• Retinal disparity

• Height in the visual field

• Figure-ground organisation

Convergence is particularly useful ______________, while retinal disparity is no longer useful beyond about ______________

• within about 6 metres; beyond about 10 metres

• within about 10 metres; beyond about 6 metres

• close up; far away

• when you are standing right next to something: when something is far away

The apparent convergence of parallel lines as they recede

• linear perspective

• height in the visual field

• relative size

• accommodation
