Cognition Flashcards
(70 cards)
What is bottom up processing?
Bottom up processing refers to the analysis that begins with the sensory receptors and works up to the brain’s integration of sensory information.
What is top down processing?
Top down processing is the interpretation of sensations influenced by our available knowledge, experiences, and thoughts.
What are schemas?
Schemas are cognitive frameworks that help organize and interpret information.
What is perceptual set?
Perceptual set is a mental predisposition to perceive one thing and not another.
What are gestalt cues?
Gestalt cues are principles that describe how we organize visual elements into groups or unified wholes.
What is retinal disparity?
Retinal disparity is the difference in images between the two eyes, which helps in depth perception.
What is convergence?
Convergence is the inward angle of the eyes focusing on a near object, aiding in depth perception.
What is selective attention?
Selective attention is the process of focusing on a particular object in the environment for a certain period.
What is the cocktail party effect?
The cocktail party effect is the ability to focus on a single conversation in a noisy environment.
What is inattentional blindness?
Inattentional blindness is the failure to notice a fully visible but unexpected object because attention was engaged elsewhere.
What is change blindness?
Change blindness is the phenomenon where a change in a visual stimulus goes unnoticed by the observer.
What is relative clarity?
Relative clarity refers to the perception that clearer objects are closer than hazy ones.
What is relative size?
Relative size is the perception that smaller objects are farther away than larger objects.
What is texture gradient?
Texture gradient is the gradual change in texture that occurs as distance increases.
What is linear perspective?
Linear perspective is a depth cue that involves parallel lines converging in the distance.
What is interposition?
Interposition is the perception that an object blocking another is closer.
What is a concept?
A concept is a mental grouping of similar objects, events, ideas, or people.
What is a prototype?
A prototype is the best example or representation of a category.
What is assimilation?
Assimilation is the process of incorporating new experiences into existing schemas.
What is accommodation?
Accommodation is the process of adjusting schemas to fit new information.
What are algorithms?
Algorithms are step-by-step procedures that guarantee a solution to a problem.
What are heuristics?
Heuristics are mental shortcuts that ease the cognitive load of making decisions.
What is the representativeness heuristic?
The representativeness heuristic is a mental shortcut used to judge the likelihood of things based on how well they match a prototype.
What is the availability heuristic?
The availability heuristic is a mental shortcut that relies on immediate examples that come to mind.
