"An excellent introduction to both the methods and the principles of psychophysiology. It delivers well on the promise of its title, providing clear and well-organized descriptions of the basic phenomena in which psychophysiologists are interested and the most efficient ways in which tomeasure them.... I would not hesitate... to recommend this book to [those] who desire a straighforward and uncomplicated initiation to the trials and tribulations of life with the polygraph.... A welcome addition to the field." --Contemporary Psychology
