10. Perceptual Organization
• The Law of Proximity: Stimulus elements that are
closed together tend to be perceived as a group
• The Law of Similarity: Similar stimuli tend to be
grouped. Similar features of various stimuli irrespective
of nearness.
• The Law of Closure: Stimuli tend to be grouped into
complete figures
• The Law of Good Continuation: Stimuli tend to be
grouped as to minimize change or discontinuity
• The Law of Simplicity: Ambiguous stimuli tend to be
resolved in favor of the simplest Figure.
• The Law of Figure Ground Principle: The tendency to
keep certain phenomenon in focus and other
phenomenon in background.
