No fear necessary. You have a few sticky electrodes on you (smaller than the eeg type for heart monitoring) maybe on your forehead and you either sit and watch a pin meter or listen for certain tones on the biofeedback monitor. As you slow your breathing or whatever the T is using to train you to be aware, you learn to adjust to keep "in the zone" of the wanted meter reading or tone.

It's neat, actually.

You said ED... I think T might have said EDR?

Since 1949, biofeedback has involved monitoring and feeding back information about the psycho physiological state. Traditional biofeedback uses peripheral based measures like EDR, TEMP, EMG, BVP, and Respiratory Waveform to monitor and feed back information about the status of these peripheral measures of sympathetic nervous system activity. Clients are trained to become familiar with eliciting these states, which they must consciously remember to do in their day to day lives.

EDR is electrodermal resistance/response. </font><blockquote><div id="quote"><font class="small">Quote:</font>

The feedback can be perceived as "a psycho-physiological mirror. The EDR feedback unit measures and feeds back changes in skin conductance. Skin conductance measures the changes in sympathetic arousal as produced in the perspiration of the palmar surface of the hand and correlates highly with the triggering of the fight/flight response. This is often called Galvanic Skin Response (GSR). Usually, changes in skin conductance co-vary with the changes in arousal. Namely, an increase in autonomic arousal usually results in an increase in the skin conductivity. The feedback device reflects those changes; specifically, when the conductivity increases the pitch of the feedback sound increases, when the conductivity decreases the pitch of the sound decreases.

Biofeedback helps you with peripheral responses. (Neurofeedback, which you didn't ask about, helps with CNS responses.)
