Closure principle

A principle of Gestalt psychology that stresses the individual’s need for completion. This principle states that people tend to perceive an incomplete picture as complete. That is, they tend to fill in the blank based on their prior experience. This principle explains why most of the people have no trouble reading a neon sign even when several of the letters are burnt out. Utilizations of the principle of closure in marketing strategies encourage audience participation, which increases the chance people will attend to the message.
