The placebo effect in pain reduction: The influence of conditioning experiences and response expectancies
- PsychologyInternational journal of behavioral medicine
- 1996
The results show that placebo-induced pain reduction can be obtained as a result of a conditioning procedure, independent of verbally induced expectancies, and conditioned placebo responses were evident at the subjective level and no placebo effects emerged at the physiological level.
Classical Conditioning as a Distinct Mechanism of Placebo Effects
- Psychology, BiologyFront. Psychiatry
- 2019
The results support the idea that placebo effects can be learned by classical conditioning either consciously or unconsciously, and the existing body of evidence is limited to classically conditioned placebo effects in pain, that is, placebo analgesia and nocebo hyperalgesia.
Neurobiology of Placebo Effects: Expectations or Learning? Running title: Theories of The Placebo Effect
- Psychology, Biology
- 2013
This work examined the possibility that the magnitude of objective neurochemical responses to placebo administration would depend on individual expectation-effectiveness comparisons and showed that such comparisons, and not expectations per se, predict behavioral placebo responses and placebo-induced activation of μ-opioid receptor mediated neurotransmission in regions relevant to error detection.
Nonconscious activation of placebo and nocebo pain responses
- PsychologyProceedings of the National Academy of Sciences
- 2012
Significant placebo and nocebo effects were found in both experiment 1 (using clearly visible stimuli) and experiment 2 (using nonconscious stimuli), indicating that the mechanisms responsible for placebo andNocebo Effects can operate without conscious awareness of the triggering cues.

The placebo effect: dissolving the expectancy versus conditioning debate.
- PsychologyPsychological bulletin
- 2004
The authors review the literature on the 2 main models of the placebo effect: expectancy theory and classical conditioning and suggest that classical conditioning procedures are one shaping factor but that verbal information can also shape placebo effects.
