Q

What is the process of seeing?

A
  1. the iris changes shape to allow the our pupils to let more or less light in.
  2. Muscles adjust the shape of the lens.
  3. The light gets focus on to the retina
  4. Photoreceptors on the retina stimulate the axons of ganglion cells
  5. signal travels along the optic nerve and leads to the brain

Q

What are the three main colours?

A

Green, blue, red

23
Q

What are the shortcomings of trichromatic theory

A

does not explain afterimage

24
Q

Opponent process theory

A

colours work to inhibit eachother and display their colour.

25
Q

Opponent process theory pairs

A

red and green, black and white, blue and yellow

26
Q

Negative after-image effect

A

Seeing the image in its antagonistic colour after you have looked away

27
Q

Two stage model

A

Stage one: cones respond to the three primary colours
Stage two: the signal is processed by the opponent process cells

28
Q

Sight path in brain

A

superior colliculus > thalamus > contralateral primary visual cortex

29
Q

What psychological group is used to explain vision groupings

A

gestalt psychology

30
Q

Figure ground

A

determining what is in the foreground and the background when the image is ambiguous

31
Q

Proximity

A

visual stimuli closer together must be in the same group

32
Q

Continuity

A

stimuli along the same plane must be grouped together

33
Q

Closure

A

tendency to fill in the gaps between lines to make an image

34
Q

Similarity

A

stimuli that resembles one another are grouped together

35
Q

Retinal disparity

A

viewing things slightly different out of each eye

36
Q

binocular cues

A

requiring both eyes

37
Q

monocular cues

A

requiring one eye

38
Q

Convergence

A

the inward movement of eyes to look at something close

39
Q

Interposition

A

when one object blocks part of another from our view, the blocked object looks farther way (monocular)

40
Q

Relative height

A

seeing objects higher as farther away (monocular)

41
Q

Texture gradient

A

Seeing details on the surface (monocular)

42
Q

Linear perspective

A

converging parallel lines (monocular)

43
Q

Light and shadow

A

Light as a cue to distance (monocular)

44
Q

Clarity or aerial perspective

A

tendency to see closer objects with more clarity

45
Q

Familiar size

A

the assumption that things stay the same size

46
Q

Relative size

A

seeing smaller objects as farther away

47
Q

Motion parallax

A

the relative movement of objects vs stationary objects

48
Q

monocular goal

A

to determine distance and depth

49
Q

Perceptual constancies

A

top-down processing that causes us to believe that things are unchanging despite environmental changes

50
Q

What are the types of perceptual constancies

A

colour constancy, size constancy, shape constancy

51
Q

What do infants rely on for sight

A

contrasts

52
Q

when does sight fully develop

A

8 months

53
Q

Strabismus

A

misalignment of the eyes and causes blindness in the weaker eye

54
Q

Amblyopia

A

partial or complete loss of vision due to abnormal brain development.
