ear/eye psych Flashcards
what is the low frequency (eye)
the red wavelengths
what is the low amplitude (eye)
the faded
What is the high amplitude (eye)
the bright
what is the iris
the colored muscle tissue that controls the size of pupil opening
the colored muscle tissue that controls the size of pupil opening
it changes shape to help focus images on the retina
what is the retina
the light-sensitive inner surface of the eye that contains rods and cones
rods
edge of retina that detects black/white and movement
cones
inner part of the retina that detects color
bot H
contains bipolar and ganglion cells
optic nerve
carries neural impulses from the eye to the brain (thalamus, visual cortex) and is compromised of the axons of the ganglion cells
blind spot
point of which optic nerve leaves the eye, no rods or cones
what is myopia
nearsighted vision problem
what is the high frequency (eye)
the blue wavelength
what is the first step of light
the cornea
what is the second step of light
the pupil
what is the third step for light
the lens
what is the fourth step for light
the retina
what is the cornea
the clear protective layer of the eye
what is the pupil
the small adjustable opening in the center of the eye
what is the lens
the transparent structure behind the pupil
what is hyperopia
farsighted vision problems
what is color-blindness caused by
a defect in cones
young-heimholtz trichromatic theory
the retina contains 3 different types of cones which when stimulated in combination can produce any color
opponent-process theory
theory that cones are paired together to enable color vision, activation of one color of the pair inhibits activation of the other color
motion parallex
when an object appears to move faster if it is closer to you than if it is farther away (car on highway vs plane)
retinal disparity
depth perception cue, occurs because your eyes dont see identical fields of vision
what is the low frequency (ear)
the low pitch wavelength
what is the high frequency (ear)
the high pitch wavelength
what is the low amplitude (ear)
quiet
what is the high amplitude (ear)
loud
what parts make up the outer ear
the auditory canal
auditory canal
funnels sound waves from the pinna to the eardrum
what parts make up the middle ear
the tympanic membrane (eardrum) and ossicles
tympanic membrane (eardrum)
thin layer of tissue that vibrates in response to sound waves
ossicles
transfer the sound waves from the eardrum to the oval window
what are the 3 bones of the middle ear
the incus, malleus and stapes
what parts make up the inner ear
the oval window, cochlea, basilar membrane and auditory nerve
oval window
the opening of the cochlea that vibrates when it receives the sound waves and causes the fluid inside the cochlea to move
cochlea
the coiled, bony, fluid-filled tube containing semicircular canals, the fluid vibrations trigger nerve impulses
basilar membrane
overlays the cochlea, ripples cause haircells to vibrate, this is where transduction occurs
auditory nerve
carries neural impulses to thalamus-> temporal lobe
whats the mnemonic device for hearing path
Americans Eat Octopus On Coastal Beaches (Always)
sensorineural
damage to the cochleas hair cell receptors or the auditory nerve, people may hear sound but have trouble discerning what someone is saying
conduction
damage to the mechanical system- eardrum and middle ear bones
frequency theory
when the basilar membrane vibrates in synchrony with the pitch (wavelength)
place theory
each area along the basilar membrane is tuned to a specific frequency of a sound wave
mnemonic device for light path
