Biofeedback is the operant conditioning technique in which a learner gains conscious control over his or her own biological responses. In biofeedback, the learner receives feedback about their physiological processes, such as heart rate or muscle tension, and is taught how to control them through relaxation techniques, mental imagery, or other methods. This technique has been shown to be effective in treating a variety of conditions, including hypertension, anxiety, and chronic pain.
