41
Q

retina

A

layers of neurons begin processing visual information

42
Q

accommodation

A

eye’s lens changes shape to focus on near or odd objects

43
Q

rods

A

detect vision in dim light, when cones don’t respond

44
Q

optic nerve

A

nerve carries neural impulses from the eye to the brain

45
Q

fovea

A

central focus point, around cones cluster

46
Q

feature detector

A

nerve cells responding to different specific features: edges, lines, angles. and movements

47
Q

supercell clusters

A

respond to complex patterns of information gathered from feature detectors

48
Q

parallel processing

A

processing of many parts of a problem simultaneously

49
Q

Young-Helmholtz trichromatic theory

color receptors for Young Helhmholtz trichromatic theory includes:

A

red, green and blue

51
Q

color-deficient vision

A

people who suffer form red-green deficiency

52

opponent-process theory

A

we analyze terms in three sets of opposing colors

53
Q

opponent-process theory combinations

A

red-green
yellow-blue
white-black

54
Q

pitch

A

tone’s experienced highness or lowness; depending on frequency

55
Q

frequency

A

number of complete wavelengths passing point given a certain time

56
Q

inner ear

A

intermost part of ear contains: cochlea, semicircular canals and vestibular sacs

57
Q

incoming vibrations in the middle ear

A

cause the cochleas membrane (oval window) to to vibrate

58
Q

auditory cortex

A

found in temporal lobe; processing what you hear

59
Q

place theory

A

that we hear different sounds depending on where the cochleas membrane is stimulated

60
Q

high frequencies produces (Place Theory)

A

large variations inner ear beginning of cochlea membrane

61
Q

low frequencies produce (Place Theory)

A

low frequencies at the end of the cochlea membrane

62
Q

Place theory explains how we

A

hear high pitched sounds

63
Q

frequency theory

A

the rate of neural impulses traveling up auditory nerve matches tones frequency, enabling pitch

64
Q

Frequency theory explains how

A

we hear low pitched sounds

65
