To teach a client to produce alpha waves for relaxation, which feedback method would be used?

• A. EMG feedback
• B. EEG feedback
• C. GSR feedback
• D. Heart rate feedback

Answer: (B)

Neurofeedback, or EEG biofeedback, trains a person to regulate brain activity by giving real-time feedback on brain waves. Alpha waves, in the 8–12 Hz range, are associated with relaxed wakefulness, so teaching someone to increase their alpha power helps promote relaxation. The feedback method that targets this directly is EEG feedback because it monitors the brain’s electrical activity and reinforces when alpha power rises. Other feedback types measure peripheral signals—muscle tension (EMG), skin conductance (GSR), or heart rate—which reflect arousal or relaxation in the body but don’t provide direct information about brainwave patterns, so they aren’t used to train producing alpha waves.
