Which technique uses feedback about brain waves and autonomic nervous system to help elicit a relaxation response?

• A. Biofeedback
• B. Graded Task Assignment
• C. Diversion
• D. Exposure Therapy

Answer: (A)

Biofeedback is a technique that gives you real-time information about physiological processes so you can learn to control them. Sensors monitor brain activity (brain waves) and autonomic nervous system indicators (like heart rate, skin temperature, muscle tension, or skin conductance). With this feedback, you practice relaxation strategies—such as deep breathing, progressive muscle relaxation, or guided imagery—and you begin to notice how these strategies change the feedback signals. Over time, you gain voluntary control over arousal, helping to elicit a relaxation response and reduce stress or anxiety. The other options involve different approaches—graded task assignment builds behavior through gradual challenges, diversion redirects attention, and exposure therapy involves facing feared situations—without using physiological feedback to train regulation.
