bottom-up processing
begins with sensory receptors and works up to brains intergration of sensory info (only face pieces)
top-down processing
interpret what senses detect (getting hints of who face is)
selective attention
focusing of conscious awareness on particular stimulus
selective attention ex
can’t text and drive
inattentional awareness
failing to see visible objects when attention directed elsewhere
transduction
process of converting one form of energy to another
Fechner
absolute thresholds
absolute thresholds
minimum stimulation needed to detect particular stimulus 50% of the time
difference threshold
minimum diff. person can detect between any 2 stimuli 50% of the time
webers law
to be perceived as diff, 2 stimuli must differ by constant minimum %
perceptual set
set of assumptions that affect what we perceive
what wavelength determines
hue
short wavelength is what color
bluish
long wavelength is what color
reddish
cornea
bends light, protects eye
pupil
lets light into eye
iris
controls size of pupil
lens
focuses light into an image
retina
cones and rods
cones
colors
rods
black/white
blind spot
optic nerve leaves
pathway of light
retina-optic nerve-brain
hubel and wiesel
feature detectors
parallel processing
doing multiple things at once
fechner
absolute threshold
soundwave amplitude determines
loudness
soundwave length determines
pitch
eardrum
causes vibrations
middle ear parts
hammer, anvil, stirrup
middle ear function
picks up vibrations and transmits to inner ear
inner ear
cochlea
cochlea function
trigger nerve impulses
place theory
we hear diff pitches bc waves trigger in diff parts of brain
frequency theory
brain reads pitches by monitoring frequency of impulses traveling auditory nerve
kinesthesis
sensation of movement with individual body parts
vestibular sense
sense of balance
