Perception Flashcards
Perception
Mental process how we organize/interpret info
Gestalt
Organizing pieces into a whole
Figure-Ground
Figure=focus on. Ground=Everything else
Grouping
Put things together
Similarity
They have something in common
Proximity
How close things are distance-wise
Closure
Brain fills in gaps
Continuity
Patterns will keep going
Depth perception
Ability to see 3D and judge distance
Visual cliff
Experiment testing babies’ depth perception (nature and nurture)
Binocular Cues
Depth cues requiring both eyes
Retinal Disparity
Slightly different images from each eye confuses us
Convergence
Tensions in eye muscles focusing on larger objects
Monocular Cues
Depth cues requiring only one eye
Relative size
Closer=bigger, Farther=smaller
Relative motion
Closer=move faster, Farther=move slower
Interposition
Closer=partially blocking farther object
Relative height
Closer=lower, farther=higher
Texture gradient
Closer=more detail, Farther=less detail
Relative clarity
Closer=more clear, Farther=less clear
Linear perspective
Parallel lines come together farther away
Perceptual constancy
You perceive size, shape, and lightness as unchanging
Size constancy
What actually changes is distance
Shape constancy
What actually changes is angle
Lightness constancy
What actually changes is lighting conditions
Perceptual set
A mental predisposition to see things only one way
Extrasensory Perception (ESP)
Controversial claim to perceive things we don’t sense
Illusions
When we are tricked into misinterpreting sensory info

Retinal Disparity
Tensions in eye muscles focusing on closer objects (cross-eyed)
Convergence
Depth cues requiring only one eye
