|
Perception |
The psychological process by which we interpret sensory information |
|
|
Sensation |
The stimulation of sensory receptors and transmission of sensory information to the central nervous |
|
|
Signal detection Theory |
Measure the ability to differentiate between information bearing patterns in random patterns that distract from information |
|
|
Difference threshold |
Smallest change in a stimulus that a person can notice |
|
|
Absolute threshold |
Lowest level of stimulus that a person can detect |
|
|
Sensory adaptation |
When our senses get used to constant stimuli causing us to notice them less overtime |
|
|
Visual acuity |
Sharpness or Clarity of vision indictating ability to see fine details |
|
|
After image |
Optical illusion where an image continues to appear briefly after the original stimulus has been removed |
|
|
Stroboscope motion |
Optical illusion where a rapid series of Steel images creates the perception of continuous motion |
|
|
Binocular cue |
Visual cues that rely on both eyes to perceive depth and distance accurately |
|
|
Monocular cue |
Visual cues that only require one eye to perceive depth and distance |
|
|
Gate Theory |
Spinal cord access gate allowing or blocking pain signal |
|
|
Pupil |
To monitor the amount of light that comes into the eye |
|
|
lens |
behind the pupil, allows your eyes to focus on small details. the lens is in a constant state of adjustment as it becomes thinner or thicker to accommodate the detailed input it receives |
|
|
cornea |
transparent outer layer of eye that protects and helps focus light |
|
|
retina |
area at back of eye that receives reined, visual message from front of the eye and transmits visual message to the brain using electrical signals |
|
|
photoreceptors |
located in retina, light is absorbed and transformed into electrochemical signals used by nervous system |
|
|
rods |
allows for black and white and gray and for peripheral and dim light vision |
|
|
cones |
allows for colour, daylight and well lit conditions |
|
|
middle ear |
contains ear drum, hammer, anvil, stirrup that transmits sound vibrations |
|
|
inner ear |
contains cochlea, for balance |
|
|
cochlea |
hearing, responsible for converting sound vibrations into neural signals |
|
|
pinna |
visible part of ear that collects sound waves |
|
|
auditory nerve |
carries neural signals from the cochlea to brain |
|
|
olfactory |
carries smell info from nose to brain |
|
|
receptor neurons |
specialized cells that detect sensory stimuli and transmit signals to the nervous system |
|
|
vestibular sense |
three semicular canals that provide the sense of balance, located in the inner ear and connected to the brain by a nerve |
|
|
kinethesis |
sense of body position and movements, provided by sensory receptors in muscles, tendons and joints |
|
|
blindspot |
area where the optic nerve leaves eye. no photoreceptors. |
|
|
process of smelling |
nostrils, receptor neurons, olfactory, olfactory nerve, limbic system |
|
|
taste bud facts |
collect chemical info from food, regenerate every 2 weeks, if smell is impaired perception of taste is impacted |
|
|
skin components |
temp, pain, pressure |
|
|
gestault |
the experience that comes from organizing bits of info into meaningful wholes |
|
|
proximity
|
group items together just bc of their closeness |
|
|
similarity |
think of similar objects as belonging to each other
|
|
|
continuity |
want to see smooth continuous patterns |
|
|
common fate |
think things that move together, belong together |
|
|
closure |
percieve a complete image even when our senses are missing info |
