Q

Pitch

A

Determined by frequency

34
Q

Middle ear

A

Amplifies sound

  • hammer/anvil/stirrup
  • eardrum
  • earcanal
35
Q

Cochlea

A

Snail looking thing

  • filled with fluid and cilia that transduce sound into a neural message
  • part of inner ear
36
Q

Inner ear

A

Transduce sound

  • cochlea
  • semicircular canals
  • auditory nerve
37
Q

Pinna

A

Outer ear

-collects sound

38
Q

Eardrum

A

Thin membrane that vibrates to amplify sound

-part of middle ear

39
Q

Hammer/anvil/stirrup

A

3tiny bones that help amplify the sound

-part of middle ear

40
Q

Auditory nerve

A

Connects to the brain

-part of inner ear

41
Q

Place theory

A

Pitch we hear is determined by the location the sound waves strike the cochlea
Problem-wasn’t consistently explaining the low pitch sound

42
Q

Frequency theory

A

Pitch we hear is determined by the speed that the sound waves travel
Problem-unable to explain high pitch sounds

43
Q

Sensorineural hearing loss

A

Damage to cochlea or inner ear; much harder to treat but can be treated with a cochlear implant

44
Q

Conduction hearing loss

A

Damage to outer or middle ear resulting in hearing loss; can be treated with a hearing aid

45
Q

Cochlear implant

A

Very controversial because helps basically a def person become not def anymore

Sweet

A

Need sugar/glucose for energy

51
Q

Salty

A

All cells need salt to function and balance out water

52
Q

Umami

A

Meaty

-need protein in body for functioning

53
Q

Olfactory sense

A

Smell

54
Q

Gate-control theory

A

If enough small nerve fibers are activated by pain, then the large nerve fibers will send a message of pain to the brain

55
Q

Sensory interaction

A

Smell and taste have strongest connection with each other

56
Q

Synesthesia

A

One sort of sensation produces a other

57

A

Seeing objects in three dimensions

65
Q

Visual cliff experiment

A

Experiment with infants and baby animals to see if they can perceive depth perception-> they can
-Gibson and Walk

66
Q

Binocular cues

A

Depth perception cues that need both eyes open

67
Q

Retinal disparity

A

Each eye has its own image and then put together, it gives us a sense of depth

68
Q

Phi phenomenon

A

Illusion of movement created when 2 or more lights blink on and off

69
Q

Perceptual constancy

A

Recognize objects without being deceived by changes in size, shape, color, etc.

70
Q

Monocular cues

A

Depth perception cues that only need one eye open

71
Q

Visual texture

A

We can tell that an object is closer to us if we can see more detail of its texture

72
Q

Interposition

A

We can tell if an object is closer to us if it is blocking our view of another object

73
Q

Color constancy

A

Know an object doesn’t change color based on its surroundings

74
Q

Size constancy

A

Know an object doesn’t change size based on its distance away from us

75
Q

Perceptual set

A

Perception is based on our expectations or previous experiences

76
Q

Extrasensory perception

A

Perception can occur apart from sensory imput

77
