Psychology- Sensation and Perception
| Question | Answer |
|---|---|
| Additive Color Mixing | way to produce a given spectral pattern in which different wavelengths of lights are mixed. |
| Audition | The sense of sound perception |
| Binocular Depth Cues | Cues of depth perception that arise from the fact that people have two eyes. |
| Binocular/Retinal Disparity | a cue of depth perception that is caused by the distance between a person's eyes (each eye with slightly different range) |
| Bottom-Up Processing | a hierarchical model of pattern recognition in which data are relayed from one processing level to the next, always moving to a higher level |
| Cones | Retinal cells that respond to higher levels of illumination and result in color perception |
| Cornea | The clear outer covering of the eye |
| Eardrum (Tympanic Membrane) | A thin membrane, which sound waves vibrate, that mark the beginning of the middle ear |
| Fovea | The center of the retina where cones are densely packed |
| Gustation | The sense of taste |
| Haptic Sense | The sense of touch |
| Iris | colored muscular circle on the surface of the eye; changes shape to let in more or less light |
| Kinesthetic Sense | Perception of your limbs in space (hand/eye coordination) |
| Lateral Inhibition | a visual process in which adjacent photoreceptors tend to inhibit one another |
| Monocular Depth Curves | cues of depth perception that are available to each eye alone |
| Olfaction | the sense of smell..occurs when receptors in the nose respond to chemicals |
| Olfactory Bulb | the brain center for smell located below the frontal lobes |
| Olfactory Epithelium | thin layer of tissue, within nasal cavity, that is embedded with smell receptors |
| Perception | the processing, organizing, and interpretation of sensory signals; results in internal representation of the stimulus |
| Perceptual Constancy | people correctly perceive objects as constants in their shape, color, size, and lightness, despite raw sensory data that could mislead perception |
| Pupil | Small opening in the eye. it lets in light waves |
| Receptive Field | the region of visual space to which neurons in the primary visual cortex are sensitive |
| Retina | thin inner surface of the back of the eyeball. contains the photoreceptors that transduce light into neural signals |
| Rods | retinal cells that respond to low levels of illumination and result in black and white perceptions |
| Sensation | the sense organs' responses to external stimuli and the transmission of these responses to the brain |
| Sensory Adaptation | when an observer's sensitivity to stimuli decreases over time |
| Signal Detection Theory | a theory of perception based on the idea that the detection of a faint stimulus requires a judgement. |
| Sound Wave | pattern of changes in air pressure through time that results in the percept of a sound |
| Subtractive Color Mixing | a way to produce a given spectral pattern in which the mixture occurs within the stimulus itself and is actually a physical process |
| Taste Buds | sensory receptors that transduce taste information |
| Top-down Processing | a hierarchical model of pattern recognition in which information at higher levels of processing can also influence lower "earlier" levels in the processing hierarchy |
| Transduction | a process by which sensory receptors produce neural impulses when they receive physical or chemical stimulation |
| Vestibular Sense | perception of balance |
