Bottom-Up Processing
We perceive elements by starting with the smaller, more fine details of that element and then building upward until we have a solid representation of it in our minds
Top-Down Processing
We form perceptions by starting with the larger concept or idea and then working our way down to the finer details of that concept or idea
Schema
The list of characteristics of an object (concept) that allows us to categorize
Perceptual Set
A tendency to perceive some sensory stimuli and to ignore others
Gestalt Psychology
A psychological perspective that emphasizes that the mind tends to perceive unified wholes and patterns rather than the bits and pieces that make up those wholes and patterns
Closure
Explains how humans fill in visual gaps in order to perceive disconnected parts as a whole object
Figure Ground
In order to see an object properly, you must distinguish the difference between the figure and the ground.
Proximity
People tend to organize objects close to each other into a perceptual group and interpret them as a single entity
Similarity
People tend to organize objects with similar qualities into a perceptual group and interpret them as a whole.
Attention
Focusing on one thing while ignoring other things that may be going on at the same time
Selective Attention
Focusing our conscious awareness on a particular stimulus
Cocktail Party Effect
The ability to focus one's attention a particular stimulus while filtering out a range of other stimuli
Inattentional Blindness
Failing to see visible objects because our focus is elsewhere
Change Blindness
Failing to notice changes in the environment
Binocular Depth Cues
A depth cue that requires the use of both eyes
Retinal Disparity
By comparing retinal images from the two eyes, the brain computes distance—the greater the disparity between the two images, the closer the object.
Convergence
When two eyes move inward to see near objects, and outward to see far away objects.
Monocular Depth Cues
A depth cue available to either eye alone
Relative Clarity
people judge the distance of objects by their apparent sharpness and detail
Relative Size
Allows you to determine how close objects are to an object of known size
Texture Gradient
There is a gradual change in appearance of objects from coarse to fine
Linear Perpective
Parallel lines appear to converge with distance
Interposition
Objects that block other objects tend to be perceived as closer
Apparent Movement
Visual illusion that occurs when two shapes or stimuli are presented in quick succession, creating the impression of movement
Prototypes
The typical example of the concept that demonstrates the schema
Assimilation
Fitting new information with new understanding
Accommodation
Old information is modified to incorporate new information
Algorithms
Methodical, logical rule or procedure that guarantees solving a particular problem
Heuristics
Simple thinking strategies that often allows us to make judgments and solve problems efficiently.
Representativeness Heuristic
Judging the likelihood of things or objects in terms of how well they seem to represent, or match a particular prototype….it allows people to make quick judgments.
Available Heuristic
Cognitive shortcut in which the probability of an event is determined by how easily the event can be brought to mind. You choose the alternative that is most mentally “available”.
Mental Set
Tendency for old patterns of problem solving to persist and make it impossible for us to see new ways to solve the problem.
Priming
Procedure of providing cues that stimulate memories without awareness of the connection between the cue and the retrieved memory.
Framing
How an issue is presented can significantly affect decisions and judgments.
Gambler’s Fallacy
a cognitive bias that adheres to the ideas that if something hasn’t happened recently it soon will
Sunk-cost Fallacy
a cognitive bias that makes you stay in a situation despite losing resources or benefits
Executive functions
mental skills that help us learn, work, and manage daily life, including working memory, flexible thinking, and self-control.
Creativity
The ability to form new and useful ideas
Divergent Thinking
expanding the number of possible problem solutions; creative thinking that expands in different directions
Convergent Thinking
narrowing the available problem solutions to determine the single best solution
Functional Fixedness
Tendency to think of only the familiar or typical function for objects
