Perception Deck Flashcards
(20 cards)
Gestalt Psychologist that first demonstrated insight through his chimp experiences, He noticed the problem-solving processes wasn’t slow, but sudden and reflective.
Wolfgang Kohler
He asked people to immerse their hands in cold water for 3 trials, and discovered that most patients wanted to repeat the trial that was longer, with more net pain, but less pain at the end.
Daniel Kahneman
A visual illusion in which the perception of motion is generated by a series of stationary images that are presented in rapid succession.
Stroboscopic Movement
A phenomenon that takes place when the eye looks at a stationary, bright, light in the dark for a long time, and after a period of time the light appears to move but really is not.
Autokinetic Effect
Depth cues, such as retinal disparity that depend on the use of 2 eyes
Binocular Cues
A laboratory device for testing depth perception in infants and young animals
Visual Cliffs
The ability to see object in 3 dimensions, although the images that strike the retina are 2 dimensional; allows us to judge distance
Depth Perception
The organization of the visual field into objects (the figures) that stand out from their surroundings (the ground)
Figure Ground
An organized whole. These psychologists emphasized our tendency to integrate pieces of information into meaningful wholes
Gestalt
The theory that opposing retinal processes (Red-Green)(Yellow-Blue) (White-Black), enables color vision
Opponent Process Theory
A mental predisposition to precieve one thing and not another
Perceptual sets
The environment in which a stimulus even occurs, especially as this influences memory, learning, judgement, or other cognitive processes.
Context
A concept or framework that organizes and interprets information
Schema
The theory that the retina contains 3 different color receptors - one most sensitive to red, one to green, and one to blue - which, when stimulated in combination, can produce the perception of any color
Young-Helmholtz Trichromatic theory
In vision, the ability to adjust to an artificially displaced or even inverted visual field
Perceptual adaptation
Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the objects
Color Constancy
Perceiving objects as unchanging, (having consistent shapes, size, lightness, and color) even as illumination and retinal images change.
Perceptual Constancy
An illusion of movement created when 2 or more adjacent lights blink on and off in quick succession.
Phi Phenomenon
Depth cues, such as interposition and linear perspective, available to either eye alone
Monocular Cues
A binocular cue for perceiving depth: by comparing images from the retinas in the 2 eyes. The brain computes distance - the greater the disparity (Difference) between the 2 images the closer the object.
Retinal Display
