In order to help him overcome his fear of flying, Clark's therapist has him construct a hierarchy of anxiety-triggered stimuli and then learn to associate each with a state of deep relaxation. Clark's therapist is using the technique called:

Systematic desensitization

Explanation:

Systematic Desensitization

This is simply regarded as a method of treating phobias in people. It usually involves the pairing hand in hand of relaxation with imagined phobic images along state that starts with with image that individual feared least and moves to the image that one feared the most. This theory works due to the fact that it pairs threatening images with (anxiety, relaxation) instead of (anxiety, relaxation).

Counterconditioning

This is the act of replacing bad or unfavorable responses with good or favorable response by repairing a threatening image with a relaxing image so that anxiety is replaced with a more benign response.

The type of Systematic Desensitization is largely dependant on how useful it is in treating phobias. The Systematic Desensitization with imaginal exposure is more or less effective than Systematic Desensitization In Vivo Exposure.
