Joseph Wolpe developed systematic desensitization, a technique used in behaviour therapy to help individuals overcome phobias and anxiety by gradually exposing them to their fears while teaching relaxation techniques. Aversion therapy (A) is used to discourage undesirable behaviour through negative associations. Rational emotive therapy (C) is a type of cognitive therapy that challenges irrational beliefs. Social skills training (D) focuses on improving an individual's ability to effectively communicate and interact with others. While Wolpe made contributions to cognitive-behavioural therapy, his most significant contribution was the development of systematic desensitization.
