Gestalt Principles:The Gestalt principles, developed by Wertheimer and others, describe how the human mind organizes visual elements into groups or unified wholes, rather than just perceiving individual components.
Phi Phenomenon: The phi phenomenon is an optical illusion discovered by Wertheimer, in which a rapid succession of static images appears to be a single, smooth movement.
Pragnanz: The Gestalt principle of Pragnanz, proposed by Wertheimer, states that the mind will perceive and interpret ambiguous or complex images in the simplest way possible, forming the most stable and coherent organization.
