Exploring the Effectiveness of Reinforcement in Covert Reinforcement Therapy: A Case Study.
Bernal, Guillermo; Wisocki, Patricia A.
The relative effects of imagerial covert rehearsal with attentional shifts and the use of an independent reinforcing agent in a covert reinforcement therapy were compared. A 17-year-old female student, requesting treatment for a snake phobia, served as the subject. The phobia was measured along four dimensions: behavioral approaches to a live snake, disruptive snake thoughts, anxiety ratings, and dream recall reports. After a three-week period of baseline, therapy was divided into four alternating three-week sequences of covert rehearsal and covert reinforcement, identical except for the use of the independent reinforcing stimulus in the covert reinforcement sequence and the use of a neutral stimulus in the covert rehearsal sequence. After 12 weeks, the client improved markedly in all but the subjective anxiety ratings, and a modeling and guided participation treatment phase was instituted. The results showed that the client was effectively and rapidly counter-conditioned. Also, one index of behavior change (the behavioral approach test) indicated a greater rate of progress during the covert rehearsal sequence than during the reinforcement sequences of therapy.
