Psychology chapter 4 review sensation and perception
people often subconsciously group parts of an image together because of the ______ of the parts to each other
proximity
sensory adaptation
the process by which people become more sensitive to weak stimuli and less sensitive to unchanging stimuli

________ is the sense that allows people to navigate through a crowded room or touch their noses without looking
Kinesthesis
photoreceptors
Neurons in the eye are sensitive to light are called ________ .
complementary
________ colors are located across from each other on the color circle.
membrane
a thin layer of tissue that covers or lines an organ
weakest amount of stimulus sensed
absolute threshold
retinal disparity
binocular cues for perceiving depth based on the difference between the two images of an object that the retina receives as the object moves closer

blocking prosteglandins
cochlea
bony tube in the inner ear that contains the fluids and neurons needed to transmit sounds to the brain
conductive deafness
caused by damage to middle ear which prevents amplification of sound
sensorineural deafness
caused by damage to the inner ear which damages or destroys neurons
middle ear damage
causes conductive deafness
close gap in image
closure
most signifigant part of inner ear
cochlea
complementary
colors mixed together form gray (light not pigment)
the law of ____ says that people assume that objects that move together belong together
common fate
you need hearing aides for
conductive deafness
accordig to the law of____ people usually prefer to see smooth patterns such as lines and waves not disrupted ones
continuity
monocular cues ( overlapping)
depth cues that only need one eye
loudness
determined by height of soundwaves or amplitude
difference detected between 2 stimuli
difference threshold
what is the gateway from the outer to middle ear?
eardrum
the perception of objects against a background is called_____perception
figure-ground
according to _______ theory the nervous system can only process a certain amount of information at a time
gate
law of similarity
group similar items together
retina
i am the part of the eye that acts like film on a camera
occipital lobe
i am the region in the back of the brain that processes visul information
lens
i focus vision by changing thickness based on the distance of an object being viewed.
law of continuity
idea that people prefer to see smooth patterns rather than disrupted ones
law of common fate
idea that people tend to group objects that are moving together
law of similarity
idea that people tend to group similar items together
the eardrum
is a thin membrane that vibrates when struck
the retina
is like the film in the camera
position and motion of body
kinesthesis
group moving objects together
law of common fate
smooth continous patterns
law of continuity

lessens pain by gate theory
the human eye
light travels throught the pupil into the lens reflected onto the retina the rods and cones are light receptors within the retina.or photoreceptors optic nerve sends visual information to the brain occipital lobe
resilient
marked by the ability to recover quickly
pitch
measure of how high or low a sound is and depends on frequency
the olfactory nerve
nerve that carries scent information
olfactory nerve
nerve that carries scent information (odors) to the brain
the blindspot has
no photoreceptors
if you can't see some colors you are
partially color blind
adaption
people who live in cities gradually become less bothered by traffic noise because of the process called sensory ____
psychological process that you interpret sensory stimulation
perception
cones
provide color vision blue green and red
amount of light enters determined by opening in the...
pupil
the taste system is _______ and can recover quickly from damage.
resilient
stimulation of sensory receptors and transmission of sensory information to the brain
sensation
rods
sensitive to brightness of light allows us to see black and white
can't hear certain frequencies
sensorineural deafness
you need implants for
sensorineural deafness
more sensitive to weak stimuli less to unchanging
sensory adaptiation
visual acuity
sharpness of vision
method of distinguishing sensory stimuli and account strength and variable elements
signal detection theory
the law of ________ says that people usually think of similar items as belonging together
similarity
the olfactor nerve transmits information about______ to the brain
smell

subject to change elements like - setting -physical state -mood -attitude
gate theory
suggest that the nervous system can only process a certain amount of information at a time
vestibular sense
tells you whether you are physically upright without using your eyes
closure
tendency to perceive a complete figure even if gaps exist
size constancy
tendency to perceive an object as being of one size no matter how far away the object is
color constancy
tendency to perceive objects as keeping their color even though different light might change the appearance of the color
photoreceptors are neurons
that are sensitive to light
the pitch is
the frequency of sound waves
an afterimage is
