| 917124993 | Sensation | The sense organs' detection of external stimuli, their responses to the stimuli, and the transmission of these responses to the brain | |
| 917124994 | Perception | The processing, organization, and interpretation of sensory signals; it results in an internal representation of the stimulus | |
| 917124995 | Transduction | A process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation | |
| 917124996 | Signal detection theory (SDT) | A theory of perception based on the idea that the detection of a faint stimulus requires a judgment -it is not an all-or-none process | |
| 917124997 | Sensory adaption | A decrease in sensitivity to a constant level of stimulation | |
| 917124998 | Gustation | The sense of taste | |
| 917124999 | Taste buds | Sensory organs in the oral cavity that contain the receptors for taste | |
| 917125000 | Olfaction | The sense of smell | |
| 917125001 | Olfactory epithelium | A thin layer of tissue, within the nasal cavity, that contains the receptors for smell | |
| 917125002 | Olfactory bulb | The brain center for smell, located below the frontal lobes | |
| 917125003 | Haptic sense | The sense of touch | |
| 917125004 | Audition | Hearing; the sense of sound perception | |
| 917125005 | Sound wave | A pattern of changes in air pressure during a period of time; it produces the percept of a sound | |
| 917125006 | Eardrum | A thin membrane that marks the beginning of the middle ear; sound waves cause it to vibrate | |
| 917125007 | Cornea | The clear outer covering of the eye | |
| 917125008 | Retina | The thin inner surface of the back of the eyeball; it contains the photoreceptors that transduce light into neural signals | |
| 917125009 | Pupil | The small opening in the eye; it lets in light waves | |
| 917125010 | Iris | The colored muscular circle on the surface of the eye; it changes shape to let in more or less light | |
| 917125011 | Rods | Retinal cells that respond to low levels of illumination and result in black-and-white perception | |
| 917125012 | Cones | Retinal cells that respond to higher levels of illumination and result in color perception | |
| 917125013 | Fovea | The center of the retina, where cones are densely packed | |
| 917125014 | Subtractive color mixing | A process of color mixing that occurs within the stimulus itself; a physical, not psychological, process | |
| 917125015 | Additive color mixing | A process of color mixing that occurs when different wavelengths of light interact within the eye's receptors; a psychological process | |
| 917125016 | Kinesthetic sense | Perception of the positions in space and movements of our bodies and our limbs | |
| 917125017 | Vestibular sense | Perception of balance | |
| 917125018 | Blindsight | A condition in which people who are blind have some spared visual capacities in the absence of any visual awareness | |
| 917125019 | Bottom-up processing | A hierarchical model of pattern recognition in which data are relayed from one level of mental processing to the next, always moving to a higher level of processing | |
| 917125020 | Top-down processing | A hierarchical model of pattern recognition in which information at higher levels of mental processing can also influence lower, "earlier" levels in the processing hierarchy | |
| 917125021 | Binocular depth cues | Cues of depth perception that arise from the fact that people have two eyes | |
| 917125022 | Monocular depth cues | Cues of depth perception that are available to each eye alone | |
| 917125023 | Binocular disparity | A depth cue; because of the distance between a person's eyes, each eye receives a slightly different retinal image | |
| 917125024 | Convergence | A cue of binocular depth perception; when a person views a nearby object, the eye muscles turn the eyes inward | |
| 917125025 | Perceptual constancy | Correctly perceiving objects as constant in their shape, size, color, and lightness, despite raw sensory data that could mislead perception |
