 If two objects tend to be observed within close proximity, or small temporal intervals, the objects are more likely to be perceived together.For example, the English language contains 26 letters that are grouped to form words using a set of rules.If an individual reads an English word they have never seen, they use the law of past experience to interpret the letters "L" and "I" as two letters beside each other, rather than using the law of closure to combine the letters and interpret the object as an uppercase U.
