|---|---|---|---|---|---|
| Sensation | show 🗑
|
||||
| Perception | show 🗑
|
||||
| Psychophysics | show 🗑
|
||||
| show | The statistically determined minimum level of stimulation necessary to excite a perceptual system.
🗑
|
||||
| show | Perception below the threshold of awareness.
🗑
|
||||
| show | Theory that holds that an observer's perception depends not only on the intensity of a stimulus but also on the observer's motivation, the criteria he or she sets for determining that a signal is present, and on the background noise.
🗑
|
||||
| show | The entire spectrum of waves initiated by the movement of charged particles.
🗑
|
||||
| Light | show 🗑
|
||||
| show | Able to see clearly things that are close but having trouble seeing objects at a distance; nearsighted.
🗑
|
||||
| show | Able to see objects at a distance clearly but having trouble seeing things up close; farsighted
🗑
|
||||
| show | The light-sensitive cells in the retina- the rods and cones.
🗑
|
||||
| show | Process by which a perceptual system analyzes stimuli and converts them into electrical impulses; also known as coding.
🗑
|
||||
| Visual cortex | show 🗑
|
||||
| show | The increase in sensitivity to light that occurs when the illumination level changes from high to low, causing chemicals in the rods and cones to regenerate and return to their inactive state.
🗑
|
||||
| show | Point at which half of the optic nerve fibers from each eye cross over and connect to the other side of the brain.
🗑
|
||||
| Receptive fields | show 🗑
|
||||
| Saccades | show 🗑
|
||||
| Hue | show 🗑
|
||||
| show | The lightness or darkness of reflected light, determined in large part by the light's intensity.
🗑
|
||||
| show | The depth and richness of a hue determined by determined by the homogeneity of the wavelengths contained in the reflected light; also known as purity.
🗑
|
||||
| Trichromatic theory | show 🗑
|
||||
| show | The inability to perceive different hues.
🗑
|
||||
| Opponent-process theory | show 🗑
|
||||
| Trichromats | show 🗑
|
||||
| show | People who cannot perceive any color, usually because their retinas lack cones.
🗑
|
||||
| show | People who can distinguish only two of the three basic colors.
🗑
|
||||
| show | Ability of the visual perceptual system to recognize that an object remains constant in size regardless of its distance from the observer or the size of its image on the retina.
🗑
|
||||
| difference threshold | show 🗑
|
||||
| show | experience of the difference threshold
🗑
|
||||
| show | transparent covering of the eye
🗑
|
||||
| show | colored part of the eye that regulates size of pupil
🗑
|
||||
| pupil | show 🗑
|
||||
| lens | show 🗑
|
||||
| retina | show 🗑
|
||||
| fovea | show 🗑
|
||||
| photoreceptors | show 🗑
|
||||
| show | photoreceptors that detect black, white, and gray, and movement; used for vision in dim light
🗑
|
||||
| show | photoreceptors that detect color and fine detail in bright-light conditions; not present in peripheral vision
🗑
|
||||
| optic nerve | show 🗑
|
||||
| visual acuity | show 🗑
|
||||
| show | area on retina with no receptor cells (where optic nerve leaves the eye)
🗑
|
||||
| show | simultaneously analyzing different elements of sensory information, such as color, brightness, shape, etc.
🗑
|
||||
| show | temporary decrease in sensitivity to a stimulus that occurs when stimulation is unchanging
🗑
|
||||
| frequency | show 🗑
|
||||
| show | the sense of hearing
🗑
|
||||
| show | the highness or lowness of a sound
🗑
|
||||
| timbre | show 🗑
|
||||
| show | the process by which the location of sound is determined
🗑
|
||||
| show | snail-shaped fluid-filled tube in the inner ear involved in transduction
🗑

🗑
|
||||
| show | focused awareness of only a limited amount of all you are capable of experiencing
🗑
|
||||

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.
