Blind spot means
no receptor cells
color =
mental construction
what are the three types of color receptors in the retina
red
green
blue
retina has three types of color receptors theory is
trichromatic
opponent colors are
red-green
blue-yellow
white-black
opponent colors are also called
complimentary colors
if using receotors for red, receptors for what color are turned off
green
example of opponent-process theory
look at red shape for a while then look at white wall and see green shape because complimentary receptors are turned on
our ability to see something as a whole even if it's missing some of its parts
gestalt
gestalt principles (how we group shapes)
proximity
similarity
continuity
closure
common region
connectedness
we perceive colors to be the same even if they are not because of lighting
color constancy
example of color constancy
we don't differentiate between light blue and dark blue depending on whether we look at it in the dark or in the light, we just say it's a blue shirt
we see brightness as a constant thing and adjust for lighting
brightness constancy
example of brightness constancy
cat's shiny fur stays shiny whether the cat is in sunlight or in dim light
we see shapes as the same
shape constancy
aplitude =
loudness
frequency =
pitch
amplitude = loudness; frequency = pitch
sound
sound reaches outer ear then >>>
eardrum
sound to eardrum >>>
tiny bones
stir up transmit vibration
sound reaches tiny bones >>>
shakes up the fluid in cochlea
shakes up fluid in cochlea >>>
triggers impulse in nerve fibers attached to auditory nerve
triggers impulse in nerve fibers attached to auditory nerve >>>
auditory nerve sends info to temporal lobe
tiny bones are
hammer
anvil
haptic
touch
touch receptors respond to what
pressure
warmth and cold
pain
tickling activates which receptor
pressure
wetness triggers which receptor
cold and pressure receptors
hot triggers which receptors
warm and cold receptors activated together
sensory receptors that respond to pain
nociceptors
where are nociceptors located
in small nerve fibers, send signals to the spinal cord, then to the brain
what does the brain do to distract during painful moments/endorphins
sends messages back to the spinal cord and block pain signals
receptors on the tongue are for
sweet
salty
sour
bitter
umami
gustation
taste
what lowers the number of taste buds
smoking and alcohol
olfaction
smell
when do we perceive odors
when chemical of the thing we are smelling attach to receptors at the top of the nasal cavity
how many different odors can we detect
10k
how many odor receptors do we have
350
smell becomes associated with what
memories
