Unit 2 Vocab Flashcards
(147 cards)
depth cues, such as retinal disparity, that depend on the use of two eyes
binocular depth cues
a binocular cue for perceiving depth by comparing images from the retinas in the two eyes, the brain computes distance—the greater the disparity (difference) between the two images, the closer the object.
retinal disparity
a mental predisposition to perceive one thing and not another
perceptual set
the organization of the visual field into objects that stand out from their surroundings. In non-visual settings, any time one thing is perceived despite the variety of things that could be perceived
figure and ground
depth cues, such as interposition and linear perspective, available to either eye alone.
monocular depth cues
an organized whole. These psychologists emphasized our tendency to integrate pieces of information into meaningful wholes. principles of perception, derived by the Gestalt psychologists, that describe the tendency to perceive and interpret certain configurations at the level of the whole rather than in terms of their component features
closure
analysis that begins with the sensory receptors and works up to the brain’s integration of sensory information
bottom up processing
failing to see visible objects when our attention is directed elsewhere
inattentional blindness
perceptions begin with the most general and move toward the more specific, information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations
top down processing
the processes that allow an individual to select and focus on particular input for further processing while simultaneously suppressing irrelevant or distracting information
selective attention
he ability to focus one’s attention on a particular stimulus while filtering out a range of other stimuli (i.e., noise)
cocktail party affect
an illusion of motion or change in size of a visual stimulus
apparent movement
a state in which cognitive resources are focused on certain aspects of the environment rather than on others and the central nervous system is in a state of readiness to respond to stimuli
attention
a failure to notice changes in the visual array appearing in two successive scenes
change bnlindness
one of the Gestalt principles of organization. It states that people tend to perceive incomplete forms (e.g., images, sounds) as complete, synthesizing the missing units so as to perceive the image or sound as a whole—in effect closing the gap in the incomplete forms to create complete forms
gestalt psychology
the rotation of the two eyes inward toward a light source so that the image falls on corresponding points on the foveas
convergence
a monocular depth cue occurring when two objects are in the same line of vision and the closer object, which is fully in view, partly conceals the farther object
interposition
Parallel lines that converge appear far away
linear perspective
one of the gestalt principles of organization. It states that people tend to organize objects close to each other into a perceptual group and interpret them as a single entity
proximity
Objects that appear sharp, clear, and detailed are seen as closer than more hazy objects
relative clarity
how large something is compared to another object
relative size
a collection of basic knowledge about a concept or entity that serves as a guide to perception, interpretation, imagination, or problem solving
schema
in perceptual classification tasks, the grouping of items on the basis of their shared function or membership in a similar category
similarity
the progressive decline in the resolution of textures as the viewer moves away from them
texture gradient
