front 1 sensation | back 1 the stimulation of sensory receptors and the transmission of sensory information to the brain |
front 2 perception | back 2 the process of organizing and interpreting sensory information |
front 3 absolute threshold | back 3 the smallest amount of a particular stimulus that can be detected |
front 4 difference threshold | back 4 the minimum difference that an individual can detect between two stimuli |
front 5 signal-detection theory | back 5 the idea that distinguishing sensory stimuli takes into account not only the strength of the stimuli but also such elements as setting and one's physical state, mood, and attitudes |
front 6 sensory adaptation | back 6 the process by which an organism becomes more sensitive to stimuli that are low in magnitude and less sensitive to stimuli that are constant |
front 7 pupil | back 7 the opening in the center of the eye that adjusts to allow light to enter |
front 8 lens | back 8 the transparent structure of the eye that focuses light on the retina |
front 9 retina | back 9 the light-sensitive inner surface of the eye that contains the rods, cones, and neurons that process visual stimuli |
front 10 photoreceptors | back 10 neurons that respond to light |
front 11 blind spot | back 11 the part of the retina that contains no photoreceptors |
front 12 visual acuity | back 12 keenness or sharpness of vision |
front 13 complementary | back 13 the colors across from each other on the color circle |
front 14 afterimage | back 14 the visual sensation that occurs after the original stimulus has been removed |
front 15 cochlea | back 15 the fluid-filled structure of the inner ear that transmits sound impulses to the auditory nerve |
front 16 auditory nerve | back 16 the cranial nerve that carries sound from the cochlea of the inner ear to the brain |
front 17 conductive deafness | back 17 hearing loss caused by damage to the middle ear, thus interfering with the transmission of sound waves to the cochlea |
front 18 sensorineural deafness | back 18 deafness that results from damage to the auditory nerve |
front 19 olfactory nerve | back 19 the nerve that transmits information about odors from olfactory receptors to the brain |
front 20 gate theory | back 20 the suggestion that only a certain amount of information can be processed by the nervous system at a given time |
front 21 vestibular sense | back 21 the sense that provides information about the position of the body |
front 22 kinesthesis | back 22 the sense that provides information about the position and movement of the individual body parts |
front 23 closure | back 23 the tendency to perceive a complete or whole figure even when there are gaps in sensory information |
front 24 proximity | back 24 the perceptual tendency to group together visual and auditory events that are near each other |
front 25 similarity | back 25 the perceptual tendency to group together elements that seem alike |
front 26 continuity | back 26 the perceptual tendency to group stimuli into continuous patterns |
front 27 common fate | back 27 the tendency to perceive objects that are moving together as belonging together |
front 28 stroboscopic motion | back 28 a visual illusion in which the perception of motion is generated by the presentation of a series of stationary images in rapid succession |
front 29 monocular cues | back 29 cues for distance that may be available to either eye alone |
front 30 binocular cues | back 30 visual cues for depth that require the use of both eyes |
front 31 retinal disparity | back 31 a binocular cue for perceiving depth based on the difference between the two images of an object that the retina receives as the object moves closer or farther away. |
