In 1979, Devi at the University of Illinois published an article ("About Smocks and Jocks") in which he contended that it was difficult to apply specific laboratory research to sporting situations. For instance, how can the pressure of shooting a foul shot in front of 12,000 screaming fans be duplicated in the lab? Rainer Martens contended: "I have grave doubts that isolated psychological studies which manipulate a few variables, attempting to uncover the effects of X on Y, can be cumulative to form a coherent picture of human behavior. I sense that the elegant control achieved in laboratory research is such that all meaning is drained from the experimental situation. The external validity of laboratory studies is at best limited to predicting behavior in other laboratories." Martens urged researchers to get out of the laboratory and onto the field to meet athletes and coaches on their own turf. Martens' article spurred an increased interest in qualitative research methods in sport psychology, such as the seminal article "Mental Links to Excellence."
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
