Q

After image

A

Describes a continuation of a visual sensation after removal of the stimulus

36
Q

Feature detectors

A

In the visual cortex specialize in around to detect one feature responding to shapes angles lines and movement in a field of vision

37
Q

Parallel processing

A

The ability of the brain to do many things at once for visual processing, emotion shape and death are processed simultaneously

38
Q

Audition

A

The biological process of her ears processing sound waves

39
Q

Sound waves

A

vibrations of molecules the travel through the air

40
Q

amplitude 

A

Height of the sound waves

41
Q

Frequency

A

Number of wavelength and a unit of time

42
Q

Pitch

A

Shorter wavelength equals high frequency equals higher pitch

43
Q

Pinna

A

The outer ear the visual part of the year directs waves into ear canal

44
Q

tympanic membrane

A

the ear drum, sound waves make the eardrum vibrate

45
Q

Middle ear

A

sound waves travel to vibrate the bones which are the hammer stirrup an anvil
bones concentrate the vibrations of eardrum on the cochleas oval window

46
Q

Cochlea

A

A coil fluid filled tube in the inner ear through which sound waves trigger nerve impulses
on top of the membrane or hair cells the bottom is the Besley Lee membrane and together they make nerve impulses and get sent to the auditory nerve

47
Q

Place theory

A

The hair cells on the basilar membrane of the cochlea or each tuned to activate at a specific frequency

48
Q

Frequency theory

A

we’re here pitch based on how fast the hair cells vibrate

rate of impulses and auditory nerve matches the frequency of the tone

49
Q

Locating sound

A

Sound waves one here sooner and more intensely than the other from this information our brain computes sounds location

50
Q

Conduction hear loss

A

caused by damage to mechanical system that conduct sound waves to the cochlea

Blockage swelling and fluid anything that restrict movement

51
Q

Sensory neural hearing loss

A

occurs when the inner ear cochlear auditory nerve is not functioning hearing aids are in effective once damage they are dead and cannot be fixed

52
Q

Cochlear implant

A

Advice for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea

53
Q

The McGurk affect

A

Perceptual losing when the visual perception of sound as part of the auditory information of a different sound

54
Q

Visual capture

A

when vision competes with other senses vision usually wins

55
Q

Taste

A

Chemical compounds are taste buds
five types of flavor receptor cells are sweet salty sour better and savory

Gustary transduction to the temporal lobe

56
Q

Smell

A

Chemical molecules breathe in through the nose smell receptors lie on top of nasal passage neural signals sent from olfactory bulb to the temporal lobe’s in the limbic system or smells can trigger memories and emotions

57
Q

somesthetic senses 

A

The senses of the skin allows to feel light touch pressure pain cold and warmth

inside the skin many cells that sense pressure skin is the largest organ and sent to the thalamus

58
Q

Sensory interaction

A

when one sense influences our experience of another 

59
Q

Pain

A

The bodies warning sign that something isn’t right combine with bottom up and top down processes

60
Q

Gate control theory of pain

A

There is a gate in the spinal cord that switch his pain on and off the more neurons the more pain

61
Q

Phantom limb sensations

A

Seven and 10 amputees feel pain and removed or nonexistent loves

62
Q

Kinethesis 

A

The system for sensing the position and movement of individual body parts there are sensors in your joints tendons bones and ears as well as skin sensors

63
Q

Vestibular sense

A

sense of body position movement and balance or equilibrium based on the movement of fluid start in the vestibular sacks of the inner ear hair like receptor cells detect movement of this fluid

64
Q

gestalt psychologist

emphasize the brains tendency to integrate pieces of information into meaningful holes

and perception the whole may exceed the sum of its parts our brain is more than register information about the world

69
Q

A

The difference between the visual images that each I received because of the different angles in which each eye veiws the world

70
