Rules of Perceptual Organization - Closure (Kessler)

The Rules of Perceptual Organization state how people categorize and organize stimulus information into meaningful units to make sense of the stimuli. The subcategory of closure explains how items grouped together look like a whole. When familiar objects such as circles or squares have missing parts, our brain is still able to identify the shape and fill in the missing pieces.

 

In the picture above, our brain is able to recognize a triangle even though there are no established lines or boundaries defining it. This represents closure in the Rules of Perceptual Organization.
