psy test 2 Flashcards
(121 cards)
sensation with perception
the activationof receptiors in response to environmental stimuli
perception
the mental process of interpruting the senses
sensory recpetors
specialized cells unique to every sense organ respond to different stimuli
transduction
how physical stimuli gets translated into a psychological experience
conversention of stimuli into a form the brain can understand
threshold
the amout of stimulous that is needed for the recptor cell is to be activated
absolute threshold
the smallest possible stimulous strenght that can be dected half the time
subliminal perceeption
dection of stimulous below the level of consciousness
mere exposure effect
repeasted exposure to a stimulous increases people liking of that stimulous
sensory adaptation
reduces sensativity to a stimulous due to the repatition of sensing it
you sease to notice afer you have been around it fro a long period of time
weber’s law
your likely to notice a durastic change rather then a large change
K= constant tringale= change in stimuli
vision
visual receptors cells recieve wave length of different lengths
wave lenght
distance from peak to peak
nonometer
1x10 to the power of negative 9
we can only see wight light
amplitude
the intensitity of a stimuli
measured by peak to trough of a wave lengtrh
radioent light
is visiable energy that is amitted from a object
reflection light
light that is reflected by objects
not a light
cornea
clear membrane that covers thw eye
gathers and directs incoming light
iris
colored part of your eye
also a muscle
expands and contracts due to the amount of light
pupil
the black part of your eye
lens
transperant structure behind the pupil
focuses or bend the light that enters the eye
optic nerve
back of the eye
carries visual receptor from the eye to the brain
color vision
colors reflect light
the perpetual experience of different wave length of light
hue
the length of the wave length
red
200 nanometers
longer wave length
