Description
Chapter 23 Biofeedback Study and review: Summary Biofeedback uses an electromechanical device to monitor the status or changes of a person’s physiological processes. The device immediately reports that information to the person, enabling the person to gain voluntary control over those internal processes through operant conditioning Biofeedback procedures can monitor a wide variety of physiological functions: 1. BP biofeedback monitors blood pressure 2. HR biofeedback monitors heart rate 3. GSR (galvanic skin response) biofeedback monitors skin conductivity as a measure of sweat gland activity 4. EEG (electroencephalographic) biofeedback assesses brain wave activity 5. EMG (electromyography) biofeedback monitors muscle tension 6. Thermal biofeedback assesses skin temperature as a indication of blood flow What is biofeedback? Biofeedback: Technique in which an electromechanical device monitors the status or a change of a person’s physiological processes (such as heart rate) and immediately reports that information. This information allows the person to gain voluntary control over these bodily processes through operant conditioning Instrumentation and measurement Biofeedback procedures: can monitor a wide variety of physiological functions: 1. BP biofeedback monitors blood pressure 2. HR biofeedback monitors heart rate 3. GSR (galvanic skin response) biofeedback monitors skin conductivity as a measure of sweat gland activity 4. EEG (electroencephalographic) biofeedback assesses brain wave activity 5. EMG (electromyography) biofeedback monitors muscle tension 6. Thermal biofeedback assesses skin temperature as a indication of blood flow Note that these measures are indirect and sometimes provide only inferences to internal changes (e.g. skin temperature changes suggest blood flow changes have occurred; higher temperature  greater blood flow). Two considerations why adaptation to biofeedback procedure is important: 1. People who are not familiar with biofeedback sensors and devices may feel uneasy; affects physiological readings 2. People who rushed to their appointment may have increased initial physiological readings; therefore a baseline reading allowing the person to adapt is crucial.
