Priming can occur following perceptual, semantic, or conceptual stimulus repetition. For example, if a person reads a list of words including the word "table", and is later asked to complete a word starting with "tab", the probability that he or she will answer "table" is greater than if they are not primed. Another example is if people see an incomplete sketch they are unable to identify and they are shown more of the sketch until they recognize the picture, later they will identify the sketch at an earlier stage than was possible for them the first time.
