ABSTRACT
Psychophysiologists are interested in the physiological states that accompany psychological processes in humans. The area becomes central to health psychology when the question is asked, “How do psychological processes translate into physiological changes that enhance or endanger health?” Do these physiological changes then further impact both psychological processes and health? Neither the accurate assessment of physiological states nor the inference of physiological mechanisms is simple, however. This chapter reviews issues raised in the psychophysiology of health and develops both the promise and the limitations of psychophysiological measures.
