Q

habituation

A

Once a stimulus becomes familiar and expected, sensitivity to it decreases. As a result, we do not respond as strongly to it as we did in the beginning.
Ex: When people watch scary movies, at first they react very strongly to the frightening scenes. However, the more they watch scary movies, the less they may respond to startling scenes; they become habituated.
