Mindfulness-based systematic desensitization is a technique used to gradually reduce test anxiety through relaxation and exposure to anxiety-provoking test situations. It involves two phases: 1) Practicing relaxation through automatic abdominal breathing exercises for 3 weeks to learn deep breathing. 2) Practicing systematic desensitization for 5 weeks by facing frightening test-related situations while remaining calm, to replace the anxiety response with relaxation through counterconditioning. The goal is to overcome test anxiety by gradually reducing fear when exposed to anxiety-provoking test situations while maintaining a calm, focused state of mind.
