Perceptual Interpretations Believing is Seeing 3.1.3 Flashcards
What is brightness constancy?
Ability to perceive the brightness of an object as being the same regardless of light levels
ex. snow on two different days with different light levels. The snow is the same but it was only the light from the sun that was different
What is color constancy?
An objects maintains its color even though the light illuminating (clarifying) the object changes
What is context effect?
The influence environmental factors have on you perception of a stimulus(something happening).
relates to top-down processing
What is figure-ground perception?
Helps decide where to focus your attention on and which information to overlook.
Ex. when you are looking for something you have lost
simplifying the figure and background
What are the Gestalt principles?
Proximity, closure, similarity, continuity, and Pragnaaz
What is Gestalt psychology?
How humans naturally tend to group the things they see in certain patterns
looking at a whole picture to understand instead a part of it
understating in groups
ex. you tend to group the members in a band based on patterns
gestalt = “shape of an entity’s complete form”
What is location constancy?
Ability to perceive stationary objects while moving
ex. driving but being able to see trees and stores
What is perceptual constancy?
A skill that enables you to perceive objects as stable or unchanging even though your eyes may see them differently
ex. a car getting farther down a road (same size, but the distance is changing)
What is principle of closure?
tendency to fill in the gaps and perceive the object as complete.
even when an image does not seem complete your brain tends to fill in the gaps to perceive the images as complete
What is principle of continuity?
Describes the tendency to see continuous patterns.
ex. when you see a type of continuous pattern you assume they belong together
What is principle of Pragnanz(simplicity)?
States you naturally perceive objects in their simplest form
when your brain is presented with complex objects it will do its best to simplify them much as possible
What is principle of proximity?
Objects are likely to be grouped together if they are close to each other.
What is principle of similarity?
describes how items that are similar tend to be grouped together
color, shape, size
What is shape constancy?
The fact the shape of an object is perceived as constant, irrespective of its orientation (no matter where it is)
ex. door at its different angles is still constant
What is size constancy?
Perception of an object’s size will not change, even when the object changes based on distance or angle
even though the retinal image changes depending on the distance
ex. car heading into the distance
