What is Systematic Desensitization?
1. The first step of systematic desensitization is the identification of an anxiety inducing
stimulus hierarchy.
2. The second step is the learning of relaxation or coping techniques. When the individual has been taught these skills, he or she must use them in the third step to react towards and overcome situations in the established hierarchy of fears. (relaxation training, meditation, breathing, cognitive reappraisal of imagined outcomes)
3. The goal of this process is for the individual to learn how to cope with, and overcome the fear in each step of the hierarchy.
