Hallucinogens and Psychedelics01:27

Hallucinogens and Psychedelics

302
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.
Marijuana, derived from the dried leaves and flowers of the hemp plant, contains...

CNS Stimulants: Psychedelic Agents

263
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

Altered States of Awareness01:06

Altered States of Awareness

534
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.
The ingestion of substances like stimulants or hallucinogens leads to chemical alterations in the brain...

The Placebo Effect01:54

The Placebo Effect

6.4K
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.

Group Polarization01:01

Group Polarization

35.8K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

An Overview of Psychoactive Drugs01:28

An Overview of Psychoactive Drugs

312
Psychoactive drugs impact brain function, influencing perception, mood, consciousness, cognition, and behavior. These substances are grouped based on their effects and the mechanisms by which they act.
Stimulants such as cocaine, amphetamines, and nicotine enhance brain activity, leading to increased alertness, attention, and energy. These drugs typically raise heart rate, blood pressure, and body temperature. While they can induce feelings of euphoria, their misuse can result in severe health...

Summary
This summary is machine-generated.

Psychedelics may not create new beliefs but alter how existing beliefs are influenced by emotions and suggestions. Baseline beliefs can impact psychedelic experiences and lasting changes, requiring further research for therapeutic applications.

Area of Science:

  • Neuroscience and Cognitive Psychology
  • Psychopharmacology

Background:

  • Psychedelics are experiencing a resurgence in research interest, prompting investigation into their effects on human beliefs.
  • Both clinical and social-cognitive studies suggest psychedelic use can lead to significant and enduring belief alterations.

Purpose of the Study:

  • To review the belief changes associated with psychedelic consumption and explore their underlying mechanisms.
  • To examine how psychedelics influence the formation and modification of beliefs, considering the role of affect and social suggestion.

Main Methods:

  • Literature review synthesizing findings from clinical and social-cognitive research on psychedelics and belief change.
  • Analysis of proposed mechanisms, distinguishing between de novo belief induction and modulation of existing belief processes.

Main Results:

  • Psychedelics appear to modulate the influence of affect and external suggestions on belief imputation, rather than creating entirely new beliefs.
  • Pre-existing beliefs, such as expectations about psychedelic effects, can significantly shape both acute psychedelic experiences and subsequent long-term belief modifications.

Conclusions:

  • Understanding how baseline beliefs interact with psychedelic effects is crucial for empirical investigation.
  • Further research is necessary to fully comprehend and potentially harness the impact of psychedelics on belief systems for therapeutic and general well-being applications.
