Biofeedback refers to provision of information to a person regarding one or more physiological processes in an effort to enable the person to gain some element of voluntary control over bodily functions that normally operate outside of consciousness. It is a training technique that enables an individual to gain some element of voluntary control over autonomic body functions; based on the learning principle that a desired response is learned when received information such as a recorded increase in skin temperature (feedback) indicates that a specific thought complex or action has produced the desired physiological response.
