| Process of selecting, organizing, and interpreting sensory information into meaningful patterns |
|
|
Term
|
Definition
Begins with specialized receptor cells located in our sense organs (ears, eyes, nose, tongue)
Process of detecting, converting, and transmitting raw sensory information from the external and internal environments to the brain. |
|
|
Term
|
Definition
| A type of data drivern processing that moves from the parts to the whole |
|
|
Term
|
Definition
conceptually driven and moves from the whole to the parts
(you think using your knowledge before you build) |
|
|
Term
|
Definition
| detect and process senosry information from the environment |
|
|
Term
|
Definition
| receptors convert energy from the previously detected simuli into neural impulses, which are sent along to the brain. |
|
|
Term
|
Definition
| converting sensory inputs into different sensations |
|
|
Term
|
Definition
Filtering and analyzing incoming sensations before sending a neural message to the cortex |
|
|
Term
|
Definition
| pertaining to stimuli presented below concious awareness or under the absolute threshold |
|
|
Term
|
Definition
| Decreased sensitivity due to repeated or constant stimulaton |
|
|
Term
|
Definition
| Theory that pain sensations are processed and altered by mechanisms within the spinal cord |
|
|
Term
|
Definition
| Process when the lends changes its shape so that it focus' light on the retina from objects at diffents distances |
|
|
Term
|
Definition
| An area at the back of the eye that contains special light-sensitive cells called rods and cones |
|
|
Term
|
Definition
| Visual receptor cells in the retina that detect shades of gray and are responsible for peripheral vision; most impotant in dim light and at night |
|
|
Term
|
Definition
| Visual receptor cells, concentrated near the center of the retina, responsible for color vision and fine detail: most sensitive in brightly lit conditions. |
|
|
Term
|
Definition
| A tiny pit responsible for our sharpest vision because it's filled entirely with cones |
|
|
Term
|
Definition
| Near the fovea, where blood vessels and the optic nerve enter and exit the eyeball. |
|
|
Term
|
Definition
|
|
Term
| Hyperopia (farsightedness) |
|
Definition
|
|
Term
|
Definition
| Theory stating that color perception results from three types of cones in the retina, each most sensitive to either red, green, or blue. Other colors result from a mixture of these three. |
|
|
Term
|
Definition
| THeory that color perception is based on three systems of color opposites; blue-yello, red-green, black-white |
|
|
Term
|
Definition
| ability to percieve 3 diff colors. Normal |
|
|
Term
|
Definition
| ability to percieve 2 different colors |
|
|
Term
|
Definition
| ability to only see one system of colors such as black and white,-colorblind |
|
|
Term
|
Definition
Light is composed of waves of electromagnetic energy of a certain wavelength.
wavelength- determines its hue(color)
Frequency- how often a light or a sound wave cycles
Amplitude(height)- determines its intensity |
|
|
Term
Identify the key structures and functions of the eye
(couple rich photographers) |
|
Definition
Light first enters through the cornea
then the pupil and lens
then the retina
then the fovea which is filled with cones |
|
|
Term
|
Definition
| Pitch perception corresponds to the particular spot (or place) on the basilar memberane that is most stimulated) |
|
|
Term
|
Definition
| Explains that pitch perception occurs when nerve impulses sent to the brain math the frequency of the sound wave. |
|
|
Term
|
Definition
| problems with transferring sound waves to the cochlea |
|
|
Term
|
Definition
| damage to the inner ear or auditory nerve |
|
|
Term
| Identify the three key parts of the ear |
|
Definition
Outer Ear- conducts sound waves to the middle ear
Middle Ear- Conduct vibrations to the inner ear.
Inner ear-Hair cells in Inn. Ear are bent by trav wave in the fluid of the cochlea.
Cochlea-transduced into neural impulses. Carried along the auditory nerve to the brain.

Definition
| Sense of body orientation and position with respect to gravity/ Sense of balance |
|
|
Term
|
Definition
| Sense that provides the brain with information about bodily posture and orientation, as well as bodily movement. |
|
|
Term
|
Definition
| Filtering out and attending only to important sensory messages |
|
|
Term
| Feature detectors (feature analyzers) |
|
Definition
| Respond only to certain sensory information (faces) |
|
|
Term
|
Definition
| Tendency of the brain to ignore environmental factors that remain constant |
|
|
Term
| What is the selection process and its its three factors |
|
Definition
The selection process allows us to choose which of the billions of separate sensory messages will eventually be processed.
Selective Attention-process of filtering out and attending only to important sensory messages.
Feature detectors-Specialized brain cells that distinguish between different sensory inputs
Habituate-adapt to unchanging stimuli and only pay attention when stimuli change |
|
|
Term
|
Definition
| Tendancy for the environment to be perceived as remaining the same even with changes in sensory input |
