Chapter 3: Sensation and perception Flashcards
sensory input from our specialized sensory receptors
sensation
translation of sensory input into neural activity
transduction
specialized forms of neurons
sensory receptors
how much a stimulus has to change for you to notice (50%)
just noticeable difference
minimum amount of stimulus that you can detect 50% of the time
absolute threshold
the tendency of sensory receptors cells to become less responsive to a stimulus that is unchanging
sensory adaptation
which part of the eye is the transparent outer layer
cornea
which part of the eye is the hole in the iris
pupil
which part of the eye is the color muscle
iris
which part of the eye changes shape to bring objects into focus
lens
which part of the eye doesn’t require light and has less visual activity
rods
which part of the eye detects color; visual activity
cones
which part of the eye has no rods or cones and where the optic nerve leaves the eye and takes it to the thalamus nerve
blind spot
what theory says that there are 3 types of cones and detect red-green, blue-yellow, black-white and is the only theory that can explain after images
opponent process theory
which part of the ear is the outer part and collects sound waves and sends down canal
pinna
which part of the ear is the tunnel that goes down to your eardrum
auditory canal
which part of the ear vibrates
eardrum
what are the 3 bones in the middle ear
malleus, incus, and stapes
which part of the ear amplifies the vibrations
the three bones in the middle ear
which part of the ear has tiny tiny sound waves sent through here
oval window
which part of the ear that lines the basilar membrane
cochlea
which part of the ear has hair cells
basilar membrane
which part of the ear does the transduction in the ear
organ of corti/hair cells
which part of the ear goes to the thalamus
auditory nerve
when the 3 bones in the middle ear don’t move and can’t get into sound waves causes what
conduction hearing impairment
damaged hair cells and can’t make it to transduction causes what
nerve hearing impairment
which part of the ear is responsible for taking the new neural info to the brain
auditory nerve
T or F according to gestalt laws of grouping, we tend to avoid grouping objects in our environment because this may complicate perception
false
which gestalt law of grouping says we fill in missing info to create a complete object to make perception easier
closure
if the lens has trouble flattening out for visual accommodation you are said to be
far sighted
the process of changing sensory input to neural info that the nervous system can use so we can perceive what is happening in our environment is called
transduction
which part of the ear is responsible for transduction
hair cells/organ of corti
which part of the depth perception cues works in both real life and artwork because we know that nearby objects typically hide part of an object that is farther away
overlap
rods and cones are located where in the eye
fovea
the minimum amount of change to a stimulus that’s needed for someone to notice there was a change is called
just noticeable difference
