Biofeedback is used to teach people to control which of the following?

• A. Cognitive distortions
• B. Bodily functions such as heart rate and muscle tension
• C. Language development
• D. Social skills

Answer: (B)

Biofeedback trains people to regulate physiological processes by providing real-time feedback from the body. Using sensors, individuals learn to influence bodily signals such as heart rate, muscle tension, skin temperature, and breathing. Through techniques like paced breathing, progressive relaxation, and visualization, they gain voluntary control over autonomic responses that are normally automatic. That’s why the option describing bodily functions like heart rate and muscle tension is correct. The other choices involve cognitive processes (changing thoughts), language development, or social skills, which are addressed by different approaches rather than biofeedback.
