Psy100-OSU-Sens/Per
Psych 100 -- OSU - Sensation & Perception
| Question | Answer |
|---|---|
| Sensation | detection of physical energy by sense organs, which then send information to the brain |
| Perception | the brain's interpretation of raw sensory inputs |
| transduction | the process of converting external energy or substance into neural acitvity |
| sense receptor | specialized cell responsible for converting external stimuli into neural acitvity for a specific sensory system |
| absolute threshold | lowest level of a stimulus needed for the nervous system to detect a change 50 percent of the time |
| just noticeable difference (JND) | the smallest change in the intensity of a stimulus that we can detect |
| perceptual constancy | the process by which we perceieve stimuli consistently across varied conditions |
| selective attention | process of selecting one sensory channel and ignoring or minimizing others |
| extrasensory perception (ESP!?!) | perception of events outside the known channels of sensation |
| brightness | intensity of reflected light that reaches our eyes |
| hue | color of light |
| sclera | the white part of eye |
| fovea | the part of the retina where light eays are most sharply focused |
| retina | innermost layer of the eye, where incoming light is converted into nerve impulses |
| lens | transparent disk that focuses light rays for near or distant vision |
| cornea | curved, transparent dome that bends incoming light |
| iris | colored area eye containing muscles that control pupil |
| pupil | opening in the center of the ires that lets in light |
| accommodation | changing the shape of the lens to focus on objects nbear or far |
| rods | receptor cells in the retina allowing us to see in low levels of light |
| acuity | sharpness of vision |
| cones | receptor cells in the retina allowing us to see in color |
| blind spot | part of the visual field we cant see because of an absence of rods and cones |
| trichromatic theory | idea that color vision is based on our sensitivity to three different colors |
| color blindness | inability to see some or all colors |
| monocular depth cues | stimuli that enable us to judge depth using only one eye |
| binocular depth cues | stimuli that enable us to judge depth using both eyes |
| audition | our sense of hearing |
| timbre | complexity or quality of sound that makes musical instruments, human voices, or other sources sound unique |
| cochlea | bony spiral-shaped sense organ used for hearing |
| organ of Corti | tissue containing the hair cells necessary for hearing |
| basilar membrane | membrane supporting the organ of corti and hair cells in the cochlea |
| olfaction | our sense of smell |
| gustation | our sense of taste |
| taste buds | sense receptors in the tongue that respond to sweet, salty, soury, bitter, umami, and perhaps fat. |
| pheromones | odorless chemicals that serve as social signals to members of one's species |
| somatosensory | our sense of touch, temperature, and pain |
| proprioception | our sense of body position |
| vestibular sense | our sense of equilibrium or balance |
| phantom pain | pain or discomfort felt in an amputated limb |
| synesthesia | rare blending of senses that occurs from activation of multiple brain regions simultaneously |
| proximity | gestalt principle where close objects tend to be recognized as unified holes |
| similarity | gestalt principle (red & yellow dots thing) |
| good continuation | gestalt principle - we still see objectes as wholes even if other objects block part of them |
| closure | ------- (one solid line) |
| symmetry | we percieve objects that are similarly arranged as wholes more often than those that arent |
