The Gestalt psychology proposes perception occurs through entire objects or scenes rather than through specific components. This idea is supported by different laws that include proximity, similarity, closure, etc. In the case of closure law, this states humans perceive objects, messages, etc. as a whole even when there are gaps. According to this law, visual gaps are filled by the mind, and due to this, images and objects are perceived as being complete. This law applies to the case presented because even when you cannot see clearly the word "OPEN" you perceive it as complete and this is the result of your mind filling the gaps in the word.
