The authors provide an overview of the literature on the ability of respons
e expectancies to elicit automatic responses in the form of self-fulfilling
prophecies and link it to the broader psychological investigation of autom
atic processes. The authors review 3 areas of research in which response ex
pectancies have been shown to affect experience, behavior, and physiology:
placebo effects, the effects of false biofeedback on sexual arousal, and th
e alteration of perceptual and cognitive functions by hypnotic and nonhypno
tic suggestion. Also reviewed are data suggesting that all behavior includi
ng novel and intentional behavior is initiated automatically. Following thi
s review, the authors summarize some of the ways in which knowledge of resp
onse expectancy effects and other automatic processes that influence experi
ence and behavior can enhance clinical practice.
