Question 6

What are visual constancies?

Answer 6

They allow us to see things as remaining the same even though their physical characteristics are constantly changing

Answer 7

Shape constancy
Colour constancy

Question 8

What is shape constancies?

Answer 8

Ability to perceive the shape of an object as constant even if it appears to change through movement.

Question 9

Question 10

Grouping
Similarity

Question 11

Question 12

What is the principle of similarity?

Answer 12

Things which share visual characteristics such as shape, size, colour, texture, value or orientation will be seen as belonging together.

Question 13

What is continuity?

Answer 13

Tendency of people to organise visual elements into unified wholes.

Question 14

What is depth perception?

Answer 14

Ability of our eyes and brain to add a third dimension or depth to everything we see.

Question 15

What are depth cues?

Answer 15

Factors that allow us to add a third dimension.

Question 16

What are some depth cues?

Answer 16

Linear perspective
Two heights in plane
Relative size
Superimposition/ overlap
Texture gradients

Question 17

What is linear perspective?

Answer 17

Parallel lines appear to converge

Question 18

What are 2 heights in plane?

Answer 18

If an image in higher to the eye, it is often seen as being further away than objects to the lower

Question 19

What is relative size?

Answer 19

When we expect things to be the same size and they are not; we interpret this as meaning that they are further away.

Question 20

What is superimposition/overlap?

Answer 20

When we can’t see the whole of an object we assume that there is something in front of it allowing us to interpret it as further away.

Question 21

What are texture gradients?

Answer 21

Where we can see the details of objects that are close bu the detail fades further away it is.

Question 22
