Unit 2 Vocab Flashcards
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
occurs when mental focus is on multiple tasks or ideas at once
divided attention
already existing structures are changed to accommodate new information
accommodation
cognitive processes that allow individuals to generate, organize, plan, and carry out goal-direct behaviors and experience critical thinking
executive functions
new information is incorporated into an already existing cognitive structure
assimilation
a methodical, logical rule or procedure that guarantees solving a particular problem.
algorithms
estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common.
availability heuristic
judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes; may lead us to ignore other relevant information
representativeness heuristic
a simple thinking strategy that often allows us to make judgments and solve problems efficiently
heuristics
critical thinking in which an individual uses linear, logical steps to analyze a number of already formulated solutions to a problem to determine the correct one or the one that is most likely to be successful
convergent thinking
the ability to produce novel and valuable ideas
creativity
creative thinking in which an individual solves a problem or reaches a decision using strategies that deviate from commonly used or previously taught strategies; in early stages of creativity, quantity is more important than quality
divergent thinking
the way an issue is posed; how an issue is presented can significantly affect decisions and judgments
framing
the tendency to think of things only in terms of their usual functions; an impediment to creativity and problem solving
functional fixedness
a tendency to approach a problem in one particular way, often a way that has been successful in the past
mental set
the activation, often unconsciously, of certain associations, thus predisposing one’s perception, memory, or response
priming
a mental image or best example of a category
prototype
a failure to recognize the independence of chance events, leading to the mistaken belief that one can predict the outcome of a chance event on the basis of the outcomes of past chance events
gamblers fallacy
the tendency to continue a course of action in which one has already invested money, time, or effort
sunk cost fallacy
all the mental activities associated with thinking, knowing, remembering, and communicating.
cognition
a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence
confirmation bias
the tendency to be more confident than correct—to overestimate the accuracy of our beliefs and judgments
overconfidence
clinging to one’s initial conceptions after the basis on which they were formed has been discredited
belief perserverence
a great boost to creativity; doing something for its own reward
intrinsic motivation
the tendency, after an event has occurred, to overestimate the extent to which the outcome could have been foreseen
hindsight bias
the tendency in forming perceptions to give excessive weight to the starting value
anchoring bias
creative thinking that deliberately attempts to reexamine basic assumptions and change perspective or direction to provide a fresh often indirect approach to solving a problem
divergent thinking
the tendency to interpret events in a way that assigns credit for success to oneself but denies one’s responsibility for failure, which is blamed on external factor
self serving bias
a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second
iconic memory
a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds.
echoic memory
retention independent of conscious recollection, non-declarative memory
implicit memory
the process of getting information out of memory storage
retrieval
memory of facts and experiences that one can consciously know and “declare.”
explicit memory
encoding that requires attention and conscious effort
effortful processing
the memory for intentions, remember to do something ahead of time
prospective memory
