A system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state is called?

• A. Biofeedback
• B. Neurofeedback
• C. Cardiofeedback
• D. Hydration feedback

Answer: (A)

Biofeedback is the process of using sensors to monitor a physiological parameter—such as muscle tension, heart rate, skin temperature, or even brain activity—then amplifying and feeding that information back to the person so they can learn to regulate it. The description in the question fits this idea precisely: electronically recording the state, amplifying the signal, and providing feedback to help the person modulate that subtle bodily state. Neurofeedback is a specialized form focused on brain activity, cardiofeedback would refer to heart-related signals, and hydration feedback isn’t a standard term for this concept.
