Dishabituation

Simply put, dishabituation is the way we respond to an old stimulus as if it were new again. When we repeatedly experience a stimulus, we eventually get used to it, and stop responding the same way we did when we first encountered it. We become habituated to it and stop paying attention until we are given a new stimulus.Then when we are once again given the original stimulus, we respond to it with a renewed interest. The previous habituation to it has been reversed.
