Definition
-talks about how we are able to pull specific sounds out of background noises
-assumes there is no absolute threshold instead detection depends on persons' experience and alertness |
|
|
Term
|
Definition
| below absolute threshold for awareness |
|
|
Term
|
Definition
| unconscious activation of certain associations thus predisposing a response |
|
|
Term
|
Definition
| minimum difference between two stimuli required for detection 50% of the time |
|
|
Term
|
Definition
| two stimuli must differ at a constant minimum percentage to be perceived as different |
|
|
Term
|
Definition
| things become easy to be ignored due to overexposure |
|
|
Term
|
Definition
| transforming of stimulus energies like smells into neural impulses that can be interpreted |
|

|
Definition
| dimension of color determined by wavelength of light |
|
|
Term
|
Definition
amount of energy in a light or sound wave which we see as how bright or loud something is
-wave amplitude |
|
|
Term
|
Definition
| opening in the center of the eye where light enters |
|
|
Term
|
Definition
ring of muscle tissue that forms colored portion of the eye
-controls how much pupil opens |
|
|
Term
|
Definition
| transparent structure behind pupil that changes shape and helps retina focus images |
|
|
Term
|
Definition
contains rods and cones
where visual info is processed |
|
|
Term
|
Definition
| process by which eye's lens changes to focus on something |
|
|
Term
|
Definition
detect black,gray, white
peripheral and twilight vision |
|
|
Term
|
Definition
color and detail
functions in daylight |
|
|
Term
|
Definition
| nerve that carries neural impulses from eye to brain |
|
|
Term
|
Definition
point at which optic nerve leaves eye
where no receptor cells are located |
|
|
Term
|
Definition
| central focal point in retina where cones are |
|
|
Term
|
Definition
| nerve cells that respond to shape, angle or movement |
|
|
Term
|
Definition
processing many things simultaneously
vision |
|
|
Term
| Three-color Theory (Young-Helmholtz trichromatic) |
|
Definition
theory that retina contains 3 different color receptors that produce perception of any color
red, green, blue |
|
|
Term
|
Definition
theory that opposing retinal processes enable color vision.
Some cells are stimulated by green and inhibited by red. |
|
|
Term
|
Definition
| number of complete wavelengths that pass a point at a given time |
|
|
Term
|
Definition
| tone's highness or lowness |
|
|
Term
|
Definition
| between eardrum and cochlea containing hammer,anvil, stirrup that concentrate vibration |
|
|
Term
|
Definition
| fluid-filled tube in inner ear through which sound waves trigger nerve impulses |
|
|
Term
|
Definition
| innermost part of year containing cohlea, semicircular canals, vestibular sacs |
|
|
Term
|
Definition
| links the pitch we hear with the place where the cochlea's membrane is stimulated |
|
|
Term
|
Definition
| rate of nerve impulses traveling up the auditory nerve matches frequency of tone enabling us to sense pitch |
|
|
Term
|
Definition
| damage to system that sends waves to the cochlea |
|
|
Term
| sensorineaural hearing loss |
|
Definition
| hearing loss caused by damage to the cochlea's receptor cells or to auditory nerves |
