Perception Flashcards
Unit 3
The process of organizing and interpreting sensory info:
Perception
We must perceive a figure from its ground:
Form Perception
Transforms 2D into 3D:
Depth Perception
Brain computes motion as images move across the retina:
Motion Perception
How we recognize an object:
Perceptual Interpretation
The ability to attend selectively to one voice among many:
Cocktail Party Event
Inability to see an object or person in our midst
Inattentional Blindness
A form of inattentional blindness; when you do not notice when something changes because you are so focused on something else:
Change Blindness
What are two perceptual illusions?
Muller-Lyer and Ames Room
Muller-Lyer
Tall arch - the ___ dimension of the arch looks longer than the ____ dimension. However, both are the same:
Vertical; Horizontal
Designed to demonstrate the size-distance illusion:
Ames Room
The tendency for vision to dominate the other senses:
Visual Capture
The tendency to integrate pieces of info into meaningful wholes:
Gestalt
Gestalt - an ____ ___:
Organize Whole
Gestalt Psychologists are fond of the saying that in perception ___ ____ may exceed the sum of its parts:
The Whole
People tend to perceive objecs in a simple, orderly way:
Law of Pragnanz
The organization of the visual field into objects that stand out from their surroundings:
Figure-ground
The perceptual tendency to organize stimuli into coherent groups:
Grouping
Group nearby figures together:
Proximity
Group figures that are similar:
Similarity
Perceive continuous patterns:
Continuity
Spots, lines, and areas are a unit when connected:
Connectedness
Fill in the gaps:
Closure
Depth perception is the ability to see things in ___ and it allows us to judge ____:
3D; Distance
Who created the Visual Cliff?
Eleanor Gibson and Richard Walk
Suggested that human infants have depth perception:
Visual Cliff
Require both eyes:
Binocular Cues
Available to each eye separately; used by artistss:
Monocular Cues
Images from the two eyes differ; closer the object, the longer the disparity:
Retinal Disparity
Neuromuscular cue; two eyes move inward for new objects:
Convergence
Convergence
The brain uses the ___ at which the eyes are turned to gauge distance:
Angle
Smaller image is more distant:
Relative Size
If one object partially blocks another, we perceive it as closer:
Interposition
Hazy objects are seen as more distant:
Relative Clarity
Course objects appear closer and fine objects are distant:
Texture Gradient
Objects higher in our field of vision appear farther away; vertical is longer than horizontal
Relative Height
Closer objects seem to move faster:
Relative Motion
Parallel lines appear to converge with distance:
Linear Perspective
Closer objects appear brighter; shading produces depth:
Light and Shadow (Relative Brightness)
Objects traveling towards us grow in size and those moving away shirk in size:
Motion Perception
An illusion of movement created when two or more adjacent lights blink on and off in succession:
Phi Phenomenon
The brain will interpret a rapid series of slightly varying images as continuous movement:
Stroboscopic Movement
Perceiving objects as unchanging even as illumination and retinal images change:
Perceptual Constancy
Our brains have a template for everything we need to know and we match what we see to the templates:
Template Matching
We see what the best example of something is and see if they are close enough to match:
Prototype Matching
We break down a feature into parts and analyze what it is:
Feature Analysis
Knowledge comes from inborn ways of organizing sensory experiences:
Immanuel Kant
Shows our perception is influence by our environment:
Blakemore and Cooper
Visual ability to adjust to an artificially displaced visual field:

A mental predisposition to perceive one thing and not another:
Perceptual Set
Concepts that organize and interpret unfamiliar information:
Schemas
Perceptual sets are determined by what?
Schemas
