ear/eye psych

Question 1

what is the low frequency (eye)

Answer 1

the red wavelengths

Question 2

what is the low amplitude (eye)

Answer 2

the faded

Question 3

What is the high amplitude (eye)

Answer 3

the bright

Question 4

what is the iris

Answer 4

the colored muscle tissue that controls the size of pupil opening

Question 5

the colored muscle tissue that controls the size of pupil opening

Answer 5

it changes shape to help focus images on the retina

Question 6

what is the retina

Answer 6

the light-sensitive inner surface of the eye that contains rods and cones

Question 7

rods

Answer 7

edge of retina that detects black/white and movement

Question 8

cones

Answer 8

inner part of the retina that detects color

Question 9

bot H

Answer 9

contains bipolar and ganglion cells

Question 10

optic nerve

Answer 10

carries neural impulses from the eye to the brain (thalamus, visual cortex) and is compromised of the axons of the ganglion cells

Question 11

blind spot

Answer 11

point of which optic nerve leaves the eye, no rods or cones

Question 12

what is myopia

Answer 12

nearsighted vision problem

Question 13

what is the high frequency (eye)

Answer 13

the blue wavelength

Question 14

what is the first step of light

Answer 14

the cornea

Question 15

what is the second step of light

Answer 15

the pupil

Question 16

what is the third step for light

Answer 16

the lens

Question 17

what is the fourth step for light

Answer 17

the retina

Question 18

what is the cornea

Answer 18

the clear protective layer of the eye

Question 19

what is the pupil

Answer 19

the small adjustable opening in the center of the eye

Question 20

what is the lens

Answer 20

the transparent structure behind the pupil

Question 21

what is hyperopia

Answer 21

farsighted vision problems

Question 22

what is color-blindness caused by

Answer 22

a defect in cones

Question 23

young-heimholtz trichromatic theory

Answer 23

the retina contains 3 different types of cones which when stimulated in combination can produce any color

Question 24

opponent-process theory

Answer 24

theory that cones are paired together to enable color vision, activation of one color of the pair inhibits activation of the other color

Question 25

motion parallex

Answer 25

when an object appears to move faster if it is closer to you than if it is farther away (car on highway vs plane)

Question 26

retinal disparity

Answer 26

depth perception cue, occurs because your eyes dont see identical fields of vision

Question 27

what is the low frequency (ear)

Answer 27

the low pitch wavelength

Question 28

what is the high frequency (ear)

Answer 28

the high pitch wavelength

Question 29

what is the low amplitude (ear)

Answer 29

quiet

Question 30

what is the high amplitude (ear)

Answer 30

loud

Question 31

what parts make up the outer ear

Answer 31

the auditory canal

Question 32

auditory canal

Answer 32

funnels sound waves from the pinna to the eardrum

Question 33

what parts make up the middle ear

Answer 33

the tympanic membrane (eardrum) and ossicles

Question 34

tympanic membrane (eardrum)

Answer 34

thin layer of tissue that vibrates in response to sound waves

Question 35

ossicles

Answer 35

transfer the sound waves from the eardrum to the oval window

Question 36

what are the 3 bones of the middle ear

Answer 36

the incus, malleus and stapes

Question 37

what parts make up the inner ear

Answer 37

the oval window, cochlea, basilar membrane and auditory nerve

Question 38

oval window

Answer 38

the opening of the cochlea that vibrates when it receives the sound waves and causes the fluid inside the cochlea to move

Question 39

cochlea

Answer 39

the coiled, bony, fluid-filled tube containing semicircular canals, the fluid vibrations trigger nerve impulses

Question 40

basilar membrane

Answer 40

overlays the cochlea, ripples cause haircells to vibrate, this is where transduction occurs

Question 41

auditory nerve

Answer 41

carries neural impulses to thalamus-> temporal lobe

Question 42

whats the mnemonic device for hearing path

Answer 42

Americans Eat Octopus On Coastal Beaches (Always)

Question 43

sensorineural

Answer 43

damage to the cochleas hair cell receptors or the auditory nerve, people may hear sound but have trouble discerning what someone is saying

Question 44

conduction

Answer 44

damage to the mechanical system- eardrum and middle ear bones

Question 45

frequency theory

Answer 45

when the basilar membrane vibrates in synchrony with the pitch (wavelength)

Question 46

place theory

Answer 46

each area along the basilar membrane is tuned to a specific frequency of a sound wave

Question 47

mnemonic device for light path

Answer 47

can people let reindeer outdoors
