|---|---|---|---|---|---|
| Sensation | show 🗑
|
||||
| Perception | show 🗑
|
||||
| show | Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information.
🗑
|
||||
| Top-down Processing | show 🗑
|
||||
| Selective Attention | show 🗑
|
||||
| Inattentional Blindness | show 🗑
|
||||
| show | Failing to notice changes in the environment.
🗑
|
||||
| Psychophysics | show 🗑
|
||||
| Absolute Threshold | show 🗑
|
||||
| show | A theory predicting how and when we detect the presence of faint stimulus("signal") amid background stimulation("noise"). Assumes there's no single absolute threshold; detection depends partly on a person's experience,expectations, motivation,alertness.
🗑
|
||||
| Subliminal | show 🗑
|
||||
| Priming | show 🗑
|
||||
| Difference Threshold | show 🗑
|
||||
| Weber's Law | show 🗑
|
||||
| show | Diminished sensitivity as a consequence of constant stimulation.
🗑
|
||||
| show | Conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brains can interpret.
🗑
|
||||
| Wavelength | show 🗑
|
||||
| show | The dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth.
🗑
|
||||
| show | The amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude.
🗑
|
||||
| show | The adjustable opening in the center of the eye through which light enters.
🗑
|
||||
| Iris | show 🗑
|
||||
| Lens | show 🗑
|
||||
| Retina | show 🗑
|
||||
| show | The process by which the eye's lens changes shape to focus near or far objects on the retina.
🗑
|
||||
| show | Retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond.
🗑
|
||||
| Cones | show 🗑
|
||||
| Optic Nerve | show 🗑
|
||||
| show | The point at which the optic nerve leaves the eye, creating a "blind spot" because no receptor cells are located there.
🗑
|
||||
| show | The central focal point in the retina, around which the eye's cones cluster.
🗑
|
||||
| show | Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement.
🗑
|
||||
| Parallel Processing | show 🗑
|
||||
| show | The theory that the retina contains three different color receptors -- one most sensitive to red, one to green, one to blue -- which, when stimulated in combination, can produce the perception of any color.
🗑
|
||||
| show | The theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green.
🗑
|
||||
| Audition | show 🗑
|
||||
| show | The number of complete wavelengths that pass a point in a given time (for example, per second).
🗑
|
||||
| show | A tone's experienced highness or lowness; depends on frequency.
🗑
|
||||
| show | The chamber between the eardrum and cochlea containing three tiny bones (hammer, anvil, and stirrup) that concentrate the vibrations of the eardrum on the cochlea's oval window.
🗑
|
||||
| Cochlea | show 🗑
|
||||
| Inner Ear | show 🗑
|
||||
| show | In hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated.
🗑
|
||||
| show | In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch.
🗑
|
||||
| Conduction Hearing Loss | show 🗑
|
||||
| show | Hearing loss caused by damage to the cochlea's receptor cells or to the auditory nerves; also called "nerve deafness."
🗑
|
||||
| show | A device for converting sounds into electrical signals and stimulatiing the auditory nerve through electrodes threaded into the cochlea.
🗑
|
||||
| Kinesthesis | show 🗑
|
||||
| Vestibular Sense | show 🗑
|
||||
| Gate-control Theory | show 🗑
|
||||
| Sensory Interaction | show 🗑
|
||||
| Gestalt | show 🗑
|
||||
| show | The organization of the visual field into objects (the "figures") that stand out from their surroundings (the "ground").
🗑
|
||||
| Grouping | show 🗑
|
||||
| show | The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance.
🗑
|
||||
| Visual Cliff | show 🗑
|
||||
| Binocular Cues | show 🗑
|
||||
| Retinal Disparity | show 🗑
|
||||
| Monocular Cues | show 🗑
|
||||
| Phi Phenomenon | show 🗑
|
||||
| Perceptual Constancy | show 🗑
|
||||
| Color Constancy | show 🗑
|
||||
| Perceptual Adaptation | show 🗑
|
||||
| show | A mental predisposition to perceive one thing and not another.
🗑
|
||||
| Extrasensory Perception (ESP) | show 🗑
|
||||
| Parapsychology | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
