Module 2.1b Flashcards
(15 cards)
Gestalt
An organized whole. Gestalt psychologists emphasized our tendency to integrate pieves of information into meaningful wholes.
Figure-Ground
The organization of the visual field into objects (the figures) that stand out from their surroundings (the ground).
Grouping
The perceptual tendency to organize stimuli into coherent groups.
Depth Perception
The ability to see objects in three dimensions, although the images that strike the retina are two-dimensional; allows us to judge distance.
Visual Cliff
A laboratory device for testing depth perception in infants and young animals.
Binocular Cue
A depth cue, such as retinal disparity, that depends on the use of two eyes.
Convergence
A cue to nearby objects’ distance, enabled by the brain combining retinal images.
Retinal Disparity
A binocular cue for perceiving septh. By comparing retinal images from the two eyes, the brain computes distance–the greater the disparity (difference) between the two images, the closer the object.
Monocular Cue
A depth cue, such as interposition or linear perspective, available to either eye alone.
Stroboscopic Movement
An illusion of continuous movement (as in a motion picture) experienced when viewing a rapid series of slightly varying still images.
Phi Phenomenon
An illusion of movement created when two or more adjacent lights blink on and off in quick succession.
Autokinetic Effect
The illusory movement of a still spot of light dark roomP
Perceptual Constancy
Perceiving objects as unchanging (having consistent color, brightness, shape, and size) even as illumination and retinal images change.
Color Constancy
Perceiving familar objects as having consistent color, evenif changing illumination alters the wavelengths reflected by the object.
Perceptual Adaptation
The ability to adjust to changed sensory input, including an artificially displaced or even inverted visual field.
