For many subjectively experienced outcomes, such as pain and depression, rather large placebo effects have been reported. However, there is increasing evidence that placebo interventions also affect end-organ functions regulated by the autonomic nervous system (ANS). After discussing three psychological models for autonomic placebo effects, this article provides an anatomical framework of the autonomic system and then critically reviews the relevant placebo studies in the field, thereby focusing on gastrointestinal, cardiovascular and pulmonary functions. The findings indicate that several autonomic organ functions can indeed be altered by verbal suggestions delivered during placebo and nocebo interventions. In addition, three experimental studies provide evidence for organ-specific effects, in agreement with the current knowledge on the central control of the ANS. It is suggested that the placebo effects on autonomic organ functions are best explained by the model of 'implicit affordance', which assumes that placebo effects are dependent on 'lived experience' rather than on the conscious representation of expected outcomes. Nevertheless, more studies will be needed to further elucidate psychological and neurobiological pathways involved in autonomic placebo effects.

“…phobia), it might be speculated that their capacity for vivid imagination and an ex treme receptivity to suggestions can be both an asset and a liability in their medical care [108], Third, several studies have found inordi nate levels of hypnotizability among patients with conditions that arc known to be caused or maintained by classical or instrumental learning principles. Those conditions men tioned in this review include: asthma [15][16][17]19] hyperemesis [65]; bulimia [76][77][78]. Pre vious work [109] found the same to be true among phobic patients.…”

Asthma-like symptoms have been condi tioned in animals when allergenic sprays were repeatedly paired with neutral aerosols [ 14] or when humans have been led to believe they have had contact with an allergen [15,16] or bronchoconstricting drug [17][18][19], Clinical trials with hypnosis for asthma relief have been encouraging.

Interest in the application of hypnotic techniques for patients with medical disorders seems to rise and fall over the years. Enthusiasm for this work comes both from patients and clinicians. Often, however, these techniques are offered without regard to the psychological theories that should inform their operation and the limits that clinical and experimental research suggest. This article offers a brief description of the elements of hypnosis and a review of the history of the use of hypnotic techniques with a variety of medical problems including asthma, habits such as cigarette smoking and medical symptoms such as persistent nausea and vomiting. Special attention is placed on the psychological and physiological principles that help to establish the valid use of this technique.

“…In the majority of the research, scientists look for physical data when trying to understand this complex system, where psychological factors and emotions are involved. In this context, some respiratory changes are measured and studied, in some experiments with emotional content in films (Levenson, 1979), in contrast with saline solution inhalation, both by the action of suggestion (Luparello, 1968;McFadden et al, 1969;Neild & Cameron, 1985). In spite of this, all researchers are using a model, which follows a linear mechanism of thinking.…”
