Additive Process | Mixture of lights |
Subtractive Process | Mixture of pigments |
Afterimages | Lingering visual impression made by a stimulus that has been improved/Persistent sensations of color are followed by perception of the complementary color when the first color is removed |
Trichromatic Theory | Theory that color vision is made possible by three types of cones, some of which respond to red light, some to green and some to blue |
Opponent-Process Theory | Theory that color vision is made possible by three types of cones, some of which respond to red or green light, some to blue or yellow and some to the intensity of light |
Trichromat | Person with normal color vision |
Monochromat | Person who is sensitive to black and white only (colorblind) |
Dichromat | Person who is sensitive to black-white and either red-green or blue-yellow and hence partially colorblind |
Closure | Tendency to perceive a broken figure as being complete or whole |
Visual Perception | Process is the process by which we organize or make sense of the sensory impressions caused by the light that strikes our eyes |
Gestalt | Perception of the whole, has parts that organize into a whole which is different from sum of parts transposition |
Rubin Vase | Correlates to the figure-ground perception that created reversible figures and contours |
Proximity | Nearness, perceptual tendency to group together to group together objects that are near one another |
Similarity | Perceptual tendency to group together objects that are similar in appearance |
Continuation | Tendency to perceive a series of points or lines as having unity |
Common Fate | Tendency to perceive elements that move together as belonging together |
Top Down Processing | The usage of knowledge to organize parts of a pattern |
Bottom Up Processing | Organization of parts of a pattern to recognize |
Illusions | Sensations that give rise to misperceptions |
Stroboscopic Motion | Illusion in perception of motion which uses presented stationary images in a rapid succession |
Monocular Cues | Cues that can be perceived by only one eye |
Perspective | Cue for depth based on the convergence of parallel lines as they recede into the distance |
Texture Gradient | (monocular) Cue based on perception that closer objects appear to have rough surfaces |
Motion Parallax | Cue for depth based on perception that nearby objects move more rapidly than our own motion |
Illusions of Magnitude | Deals with people misperceiving how big something is, happens to anybody (Vertical Horizontal Illusion, Progondorf Illusion, Worthimer Illusion of Kind (formed psychology of gestalt) |
Decibal | Measures sound |
Kohler | Formed laws of organization on perception |
Perceptual Constancy | Points to instances where our perception of something remains the same (even if stimulus has changed) Examples of this are: brightness constancy, color, shape, orientation, size |
Convergence | Binocular cue based on inward movement and focus of eyes as an object draws nearer |
Accommodation | When our lens focuses the incoming light when hitting our retina |
Binocular Cues | Involves simultaneous perception by both eyes |
Cochlea | Inner ear, contains basilar membrane and organ of corti |
Basilar Membrane | Lies coiled inside cochlea |
Organ of Corti | Receptor for hearing that lies on basilar membrane |
Auditory Nerve | Axon bundle that transmits neural impulses from organ of Corti to brain |
Five Basic Dimensions of Taste | Sourness, saltiness, sweetness, bitterness, umami (richness) |
Smellen Chart | Measures visual activity |
Retinal Disparity | Proves that one image is different to one eye compared to the other when distance is involved |
