Ch.5 Flashcards
sensation
detection of stimuli by sensory receptors; physiological process
perception
way that sensory information is interpreted,organized, & consciously experienced; psychological
process
absolute threshold
minimum amount of stimulus energy that must be present
Just noticeable difference (JND)
the minimum difference in stimuli required to detect a change
JND example
dim room= small change in light is noticeable
absolute threshold example
a candle light 30fft away
habituation
the reduction in response to a repeated performed movement
habituation example
wearing a perfume everyday for weeks, your nose becomes immune and ignores the smell.
brightness
the perceptual correlate of light intensity
hue
the experience that we describe with color name labels such as red or blue
saturation
the intensity of the hue experience,
pitch
The dimension of frequency determined by the wavelength of sound
loudness
the perception of the intensity of sound
timbre
the quality of a sound or musical tone
cornea
Clear membrane that covers the
surface of the eye, protection, focuses light coming onto the eye
iris
Colored portion of the eye; muscles attached to it control pupil
lens
Curved, transparent structure behind the pupil that provides additional focus
pupil
Small opening in the eye through which light passes (black thing)
retina
Light-sensitive lining on the back of the eyeball, final stop for light in the eye
optic nerve
Carries visual information from the retina to the brain
cones
Responsible for color vision
rods
Responsible for non-color, detection of movement
pinnea (outer)
cartilage and skin that makes up visible outer ear
ear canal (outer)
an entryway for sound waves
ear drum (outer)
send vibrations to the inner ear
ossicles (middle)
which amplify sound waves
cochlea (inner)
fluid-filled, snail-shaped structure that contains basilar membrane & sensory receptors
auditory nerve ( inner)
transmitting auditory signals from the inner ear to the cochlear nuclei
audition (sense)
hearing
vision (sense)
sight
olfaction (sense)
smell
gustation (sense)
taste
somatosensation (sense)
touch
kinesthetic
body position and movement
vestibular
balance
pain
pain
pressure
stress
top-down process
using models, ideas, and expectations to interpret information, Is it something i’ve seen before?
bottom-up processing
taking and gathering information then assembling it, what am I seeing?
muller-lyer illusion
allusion where two lines of the same length appear different, often seen in cultures with angular architecture
rotating snakes
type of peripheral drift illusion, the image is static but the snakes appear to be moving in circles
