Chapter 4 - Depth Cues

Question 1

Binocular depth cues :
What is it
Examples

Answer 1

Binocular depth cues use both eyes

Retinal disparity- compares and contrasts the two slightly different images obtained because of the distance of the two eyes

Convergence- as an object comes closer to us, our eyes turn inwards to keep the image centred on the retina

Question 2

Monocular depth cues
What is it
Examples

Answer 2

Monocular depth cues only use one eye

Accommodation- involves the lens of the eye changing shape so that it can focus light rays onto the retina

Question 3

Pictorial depth cues

Answer 3

Liner perspective- parallel lime are made to converge as they extend along the page to an imagery point

Interposition- (overlap) is based on the partial blocking or obscuring of one object by another

Texture gradient- used to make surfaces in a picture appear to recede into the distance

Relative size- Is based on our tendency to perceive the object producing the smallest retinal image as being the farthest

Height in the visual field- shows us depth by portraying objects further away as being closer to the horizon
