Aversion Therapy reduces the attractiveness of a desired event by associating it with an aversive stimulus. An ancient version of this treatment was suggested by Pliny the Elder, who treated this overindulgence in wine by secretly slipping the body of large spider into the bottom of the wine drinker’s glass. (Talk about cruel, wine can be expensive!!) The intention of this was that the feelings of revulsion elicited by a mouthful of spider would become associated with the wine, reducing the person’s desire for wine. I think this therapy can be associated with overshadowing. Now whenever that wine drinker sees a glass of wine, they will correlate a large spider just hanging out in the bottom of that glass. If you want to eliminate a habit, aversion therapy will definitely do the trick. However, if anyone ever put a spider in the bottom of my glass of wine, they better run extremely fast and get me a new bottle of wine!
