Depth Cues

Question 0

Convergence

Answer 0

Binocular: both eyes turning inwards as an object moves closer

Question 1

Depth cues

Answer 1

Messages sent from the environment to our body and provide information to help us perceive depth or distance

Question 2

Retinal disparity

Answer 2

Binocular: small discrepancies between an image that reaches the right eye and one that reaches the left eye

Question 3

Monocular and binocular cues

Answer 3

Monocular: depth perception requiring information from one eye

Binocular: a group of depth cues requiring information from both eyes

Question 4

Accommodation

Answer 4

Monocular: muscles altering the lense’s shape to enable the eye to focus on nearby objects

Question 5

Pictorial cues

Answer 5

A group of monocular cues that create an impression of depth on a flat two dimensional surface where depth does not exist

Question 6

Linear perspective

Answer 6

Monocular: apparent convergence of parallel lines creating the illusion of increasing distance

Question 7

Relative size

Answer 7

Monocular: smaller retinal image of two objects is perceived as being further away and the longer retinal image of two objects is perceived as being closer

Question 8

Interposition

Answer 8

Monocular: when one object partially blocks another and is perceived as being in front (overlap)

Question 9

Texture gradient

Answer 9

Monocular: the surface features of an object become smaller and less detailed the more distant an object becomes

Question 10

Height in the visual field

Answer 10

Monocular: height of objects in the visual field (above or below the horizon) acts as a depth cue so objects can be perceived as close and far away
