Perception

Question 1

bottom-up theories

Answer 1

small details to get big picture

Question 2

name one thing that supports bottom-up theory

Answer 2

the anatomy and structural system support this - way the visual system is contstructed.

Question 3

top-down theory….

Answer 3

we may not be breaking the image down to elementary parts - how would we read?

Question 4

name 2 things that support top-down theories

Answer 4

speed of recognition is faster w more context
ambiguous/ reversible figures (duck/rabbit) - can switch between the two once you see the whole picture

Question 5

what do the interactive theories entail?

Answer 5

combine both theories of pattern perception
that they occur at the same time with similar bidirectional flow of information.

Question 6

what are categories of depth perception cues

Answer 6

binocular and monocular

Question 7

Binocular?

Answer 7

FCRD
- forward facing eyes = visual fields overlap
Convergence - eyes move together when objects are close
Divergence - opposite
Retinal disparity - L & R visual fields provide slightly dif images.

Question 8

Monocular?

Answer 8

DURRT IRLL
Depend on 1 eye
Use 3D for depth
Represented in picture/movie
Relative size
Texture gradient
Interposition
Relative height/location
Linear position - converging lines
Light/shadows

Question 9

what are the 2 theories of Colour Perception?

Answer 9

young-helmholz - trichromatic theory
Opponent process theory

Question 10

trichromatic theory?

Answer 10

there are three different cone systems in the eye that perceive three types of color: blue, green, and red.

Question 11

opponent process theory?

Answer 11

Ability to perceive colour - controlled by three receptor complexes with opposing actions.

red-green complex, the blue-yellow complex, and the black-white complex.
