This volume investigates the physiological and psychological mechanisms through which individuals can exert voluntary control over autonomic bodily processes and states of consciousness. The authors, prominent researchers in the field of psychophysiology, compile a series of studies and theoretical papers that examine the efficacy of biofeedback training. By synthesizing data from laboratory experiments, the text argues that internal biological functions, once considered involuntary, can be modulated through systematic feedback loops and cognitive regulation.

Experts recognize this annual as a foundational collection that documented the early, rapid development of biofeedback research during the 1970s. Readers frequently note the academic density of the prose, which serves as a primary source for understanding the historical shift toward self-regulatory health practices.
