Who made the tri-chromatic theory?

A

Young

25
Q

tri-chomstic theory

A

Or I received three types of colors, red, blue, green

26
Q

Feature detectors

A

Neurons that the text certain types of stimuli like movement shape, and angles

27
Q

Bipolar cells

A

One of the main retinal interneurons that creates the main pathway to ganglion cells

28
Q

Ganglion cells

A

Transport visual stimuli to the brain

29
Q

Opponent process theory

A

Ganglion cells will turn on and off when they get tired and colors rock will appear to be the opposite color

30
Q

Transduction

A

The change of the stimulus energy into neural impulses

31
Q

Photo transduction

A

Light energy into neural impulses

32

A

Color and hugh

33
Q

intensity Hass to do with what and is controlled by what

A

How to do with brightness and is controlled by the amplitude of light waves

34
Q

Where does the optic nerve go first

A

Thalamus

35
Q

Feature detection

A

Processing different things in different parts of the brain

36
Q

Color consistency

A

context of what’s around something changes how we see the color
EX. Apples pic

37
Q

Perceptual set

A

predisposed to see you one thing rather than another
EX. Young versus old lady.

38
Q

What features do we look at the most on a person?

A

Eyes and mouth

39
Q

Visual capture

A

vision can influence other senses

40
Q

McGurk effect

A

What you hear changes based on what you see
EX. Bah/fah mouth.

41
Q

gestalt grouping rules

A

proximity similarity, continuity, connectedness, and closure can affect perceptual consistency

42
Q

Retinal disparity

A

when right and left vision cross
EX. Singer sausage.

43
Q

Convergence

A

need two eyes to tell how far something is by using angles
(binocular cue)

44
Q

Monocular cue

A

need one eye to process something

45
Q

Relative size

A

Bigger equals closer

46
Q

Interposition

A

objects that block off other objects are closer
EX. Weird horse painting.

47
Q

Relative clarity

A

Foggy things look farther away

48
Q

Texture gradients

A

More texture = closer

49
Q

Relative motion

A

stuff closer that you pass goes the opposite way, but big stuff stays with you
EX. Driving past something big vs something small.

50
Q

Relative height

A

Higher up = farther away

51
Q

linear perspective/convergence

A

Angles of lines, make it seem like there is more depth
EX. Hallway drawing.

52
Q

light/shadow

A

lighter = closer
Darker = farther

53
Q

Motion perception

A

Moving closer things get bigger

54
Q

phi phenomenon

A

light flash out of speed, makes it look like there’s motion
EX. Signs with rotating lights.

55
Q

size consistency

A

stable, size perception, a midchanging size of the stimuli
Yes. Different size cars.

56
Q

size distance, relationship

A

If something seems farther away, it may seem bigger than the same size object that looks like it’s closer
EX. Monster running
