Summary
Hypnosis and placebo share similar effects, but hypnosis does not require deception. Research into hypnotizability may illuminate placebo responses, potentially revolutionizing clinical science and understanding individual differences.
Area of Science:
- Psychiatry
- Neuroscience
- Psychology
Background:
- Hypnosis and placebo phenomena share phenomenological similarities.
- Historical accounts of hypnosis span millennia, while placebo effects have been documented for centuries.
- Modern clinical research, particularly in biological psychiatry, heavily relies on placebo-controlled drug trials, sometimes involving deception.
Purpose of the Study:
- To explore the shared phenomenology of hypnosis and placebo effects.
- To contrast the methodologies of hypnosis and placebo-controlled trials, highlighting hypnosis's non-deceptive nature.
- To investigate how understanding hypnotizability and its neural correlates can elucidate placebo phenomena.
Main Methods:
- Comparative analysis of historical and contemporary accounts of hypnosis and placebo effects.
- Review of methodologies in clinical drug trials incorporating placebo controls.
- Exploration of emerging research on genetic and neural correlates of hypnotizability.
Main Results:
- Hypnosis and placebo share significant phenomenological overlap.
- Hypnosis offers therapeutic effects without the need for deception inherent in some placebo-controlled trials.
- Identifying genetic and neural markers for hypnotizability may provide insights into placebo responsiveness.
Conclusions:
- The study of hypnosis can inform our understanding of placebo effects.
- Identifying good placebo responders holds significant potential for advancing basic and clinical science.
- Further research may elucidate individual differences in response to both hypnosis and placebo, with implications for transcultural psychiatry.

01:54The Placebo Effect
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.
02:07Blind Procedures
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
01:06Altered States of Awareness
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

01:11Blinding
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
01:17Classical Conditioning in Daily Life
Classical conditioning, a fundamental principle of associative learning, explains various phenomena observed in daily life, such as fear development, the placebo effect, taste aversion, and drug habituation. These applications demonstrate the profound impact of associative learning on human behavior and physiological responses.

01:23Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
