Q

Cones

A

Color and fine detail

27
Q

Rods

A

light and dark (black and white) and peripheral vision

28
Q

schemas

A

concept frame-works that allow us to organize and interpret information

29
Q

Figure-Ground

A

We organize things into figures that stand out from our surroundings.(background)

30
Q

Proximity

A

Things that are close to on another appear to belong to the same group

31
Q

Continuity

A

We perceive a flow of items so it appears to go on even if it doesn’t

32
Q

Closure

A

Our brain fills in the gap to close of an object even if it isn’t closed

33
Q

Similarity

A

We group things that are similar to one another into the same group

34
Q

Connectedness

A

We group things that are touching one another

35
Q

Phi Phenomenon

A

Motion is perceived because lights blink to make you perceive motion.

36
Q

Stroboscopic Movement

A

Motion is produced by rapid succession of slightly varying images.

37
Q

Visual Cliff

A

Device to test depth perception in infants suggests that depth perception is innate.

38
Q

Binocular Cues

A

Used by both eyes to perceive 3D

39
Q

Retinal Disparity

A

Each eye gets a slightly different image but your brain combines them together

40
Q

Convergence

A

Ability of your eyes to turn inward to see things really close to you face

41
Q

Monocular Cues

A

Used by only one eye to perceive depth; used to see a 3D image in a 2D image

42
Q

Relative Height

A

Farther away=higher in visual field closer=lower in visual field

43
Q

Relative Motion

motion parallax

A

As we move objects that are actually stable may appear to move

44
Q

Relative Size

A

Close=larger, farther away=smaller

45
Q

Interposition

A

Something in front of another object lets you know the front object is closer.

46
Q

Linear Perspective

A

Two parallel lines appear farther apart=coser, lines getting closer to each other=farther

47
Q

Light and Shadow

A

Shading produces a sense of depth consistent with our assumption that light comes from

48
Q

Texture Gradient

A

Objects far away look smooth

Objects closer look rough

49
Q

Relative Clarity

A

Hazy objects appear farther away

50
Q

Sound waves length detriment…

A

pitch

51
Q

The three bones in the ear

A

Hammer
Anvil
Stirrup

52
Q

Sensorineural hearing loss

A

damage to hair in ear fixed with a hearing aid

53
Q

Conduction hearing loss

A

caused by damage to the mechanical system that conducts sound waves to the cochlea. fixed by cochlear implant

54
Q

Place Theory

A

location, where hair cells bends, determines high pitches

55
Q

Frequency Theory

A

How fast a neural impulses travels determines low pitches

56
Q

the gate-control theory

A

says that we experience pain only if the pain messages can pass through a gate in the spinal cord on their route to the brain.

57
Q

5 basic tastes

A

sweet, sour, bitter, salty, & umami

58

A

sense of body position and awareness of body parts in space

59

sense of balance and orientation; keeps our body upright while standing, sitting, or walking

60
Q

sensory interaction

A

one sense influence another
