Grouping
Tendency to organize stimuli into coherent groups
Proximity
Group nearby figured together
Ex: a square not all connecting
Closure
Full in gaps to see a whole object
Continuity
Want to see smooth continuous patterns. Follow straight lines
Simplicity
Want to see the simplest way possible
Similarly

Binocular cues
Depth cues that depend on the use of two eyes
Monocular cues
Depth cues available to each eye separately
Perceptual constancy
Perceiving objects as unchanging
Ex: door opening
Person standing in shade
Illusions
Relative height- perceive objects closer as shorter
Relative size
Linear perspective- parallel lines meeting in the middle
Light and shadow- provides depth
Interposition-overlap
