Which statement accurately describes biofeedback?

• A. It uses hypnosis to reduce stress.
• B. It involves monitoring brain waves for relaxation.
• C. It enables monitoring of physiological signals and learning to control them.
• D. It is a form of dream analysis.

Answer: (C)

Biofeedback centers on using instruments to monitor physiological signals—such as heart rate, muscle tension, skin temperature, and breathing—and then teaching the person ways to control those signals through practice and feedback. The idea is that by seeing real-time data about these bodily processes, a person can learn techniques (like paced breathing, progressive relaxation, or specific mental strategies) to regulate them, reducing stress or symptoms tied to autonomic arousal. This isn’t about hypnosis, nor is it limited to brain activity (neurofeedback is a related but narrower form). It also isn’t about dream analysis. Seeing and controlling these bodily signals is the core of biofeedback, making it the best description.
