In psychology, what is the difference between habituation and dishabituation?

Exposure = less fear. Habituation is the decline in response to fear-provoking stimuli with repeated exposure. Habituation is a passive process, in contrast to extinction, which involves active changes in cognition. Dishabituation is habituation in reverse, where one is resensitized to stimuli that had previously been habituated. Exposure therapy relies heavily on the concept of habituation.
