Priming is an implicit memory effect in which exposure to a stimulus influences a response to a later stimulus. It 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 not so primed. Another example is if people see an incomplete sketch that 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.[1]
It is suggesed that the priming is caused by stimulation of an areas in a local neural networks, and when further information is asked, the locay of this network is more receptive to flow of neural firing, and therefore produce answers from nearby linkes. Therefore, creating an associattions (Tal Yaron).
