A corollary of this type of tension-release theory of humor, at least of the classical Freudian version, is that once we laugh and tension is released, we should not only feel relieved but also have less of a need to release this energy in other ways, because the tension is, presumably, gone. Thus, a “catharsis” should occur, a temporary reduction of pent-up psychic energy and, importantly, a decreased tendency to engage in the tension-causing behavior. For example, if sex caused our tension, which has now been released in the form of a sexual joke, we should have a decreased need to have sex or a sexual outlet.
Is there modern scientific support for this tension-reduction model of humor, given that it is associated with some relatively ancient and oft-criticized theorists, such as Freud? There is, at least for some basic elements of the theory. Several relatively modern theorists of humor argue that some kind of tension is often important for and can enhance humor, particularly in humorous situations that evoke the act of laughter or other overtly mirthful reactions. For example, in a study by psychologists Dolf Zillmann and Jennings Bryant (1980), the authors found that when tension is high, people laugh and express more mirth. More specific to sexuality, though, there is also evidence that people who report a high degree of sexual desire (sexual tension) seem to enjoy sexual humor more than those who report lower sexual desire (Prerost, 1995).
But is there evidence that sexual tension can be
