| absolute threshold | the smallest amount of a particular stimulus that can be detected. |
| difference threshold | the minimum difference that an individual can detect between two stimuli. |
| perception | the process of organizing and interpreting sensory information. |
| sensation | the stimulation of sensory receptors and the transmission of sensory information to the brain. |
| sensory adaptation | the process by which an organism becomes more sensitive to stimuli that are low in magnitude and less sensitive to stimuli that are constant. |
| afterimage | the visual sensation that occurs after the original stimulus has been removed. |
| blind spot | the part of the retina that contains no photoreceptors. |
| complementary | the colors across from each other on the color circle. |
| Binocular Cues | Visual cues for depth that requires the use of both eyes. |
| closure | Tendency to perceive a complete or whole figure even when there are gaps in sensory information. |
| Common Fate | Tendency to perceive objects that are moving together as belonging together. |
| Conductive Deafness | Hearing loss caused by damage to the middle ear, thus interfering with the transmission of sound waves to the cochlea. |
| Continuity | Perceptual tendency to group stimuli into continuous patterns. |
| Gate Theory | Suggestion that only a certain amount of information can be processed by the nervous system at a given time. |
| Kinesthesis | The sense that produces information about the position and movement of individual body parts. |
| Monocular Cues | Cues for distance that may be available to either eye alone. |
| Proximity | Perceptual tendency to group together visual and auditory events that are near each other. |
| Retinal Disparity | 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. |
| Sensorineural Deafness | Deafness that results from damage to the auditory nerve. |
| Similarity | Perceptual tendency to group together elements that seem alike. |
| Stroboscopic Motion | A visual illustration in which the perception of motion is generated by the presentation of a series of stationary images in rapid succession. |
| Visual Acuity | Keenness or sharpness of vision. |
