Final answer:
Eduardo is likely to use systematic desensitization to help Catherine with her fear of heights by teaching relaxation techniques and gradually exposing her to imagining high places. Option D involves exposure to heights without any intervention to reduce anxiety.
Step-by-step explanation:
Eduardo, a psychologist, is likely to use the technique of systematic desensitization to help his client, Catherine, address her extreme fear of heights. This technique involves exposing the client to progressively more anxiety-inducing situations related to heights while using relaxation techniques to reduce anxiety levels. In this case, option B is the most likely technique that Eduardo will use. He will teach Catherine relaxation techniques and use guided imagery to gradually expose her to imagining herself in high places.
If she starts feeling anxious, they will temporarily return to the relaxation techniques. Option A involves exposure to heights without explicitly addressing and managing anxiety. Option C involves pleasant experiences at a scenic viewpoint, but it does not follow the systematic desensitization approach. Option D involves exposure to heights without any intervention to reduce anxiety.
