Are you familiar with the "our song" phenomenon? During a period of time when you were with someone very special, you had a favorite song you listened to a lot. Now whenever you hear that song, you think of that person and feel those good feelings again. It works just like Pavlov and salivation. Most people have no idea how easy it is to link experiences in that way, or how quickly you can make it happen if you do it systematically.

I once saw a therapist create an agoraphobic in one session. This therapist was a nice, well–intentioned man who liked his patients. He had years of clinical training, but he had no idea what he was doing. His client came in with a specific phobia of heights. The therapist told this guy to close his eyes and think about heights, Urrp—the guy flushes and starts to tremble. "Now think of something that would reassure you." Ummn. Now think about heights. Urrp. "Now think about comfortably driving your car." Ummn. "Now think about heights." Urrp. . . . This guy ended up having phobic feelings about nearly everything in his life — what's often called agoraphobia. What the therapist did was brilliant, in a way. He changed his client's feelings by linking experiences. His choice of a feeling to generalize is not my idea of the best choice, however. He linked this man's feelings of panic to all the contexts that used to be reassuring in his life. You can use exactly the same process to take a good feeling and generalize it in the same way If that therapist had understood the process he was using, he could have turned it around.

I've seen the same thing happen in couple therapy. The wife starts complaining about something the husband did, and the therapist says, "Look at your husband while you say that. You've got to have eye contact." That will connect all those bad feelings to the sight of her husband's face, so that every time she looks at him, she'll have those bad feelings.
