Altered States of Consciousness: Hypnosis, Meditation, and Psychoactive Drugs

Hypnosis

  • Opening discussion: questions about having been hypnotized, experiences with hypnotists, and whether hypnosis creates an altered state of consciousness or simply follows suggestions.
  • Mixed intuitions in class: some believe an altered state, others believe people just go along with the suggestions.
  • In therapeutic settings, hypnosis typically involves relaxation of mind and body to facilitate processing information and accessing memories or thoughts more easily.
  • Hypnosis vs altered state distinction:
    • Altered state of consciousness (ASC): external world clarity can increase or decrease; examples include meditation (internal focus) or intoxication (external clarity reduced).
    • Hypnosis is a process that can alter memory, perception, and voluntary action in some people, but there is no universal consensus that hypnosis always produces a global ASC.
  • Definitions:
    • ASC: when consciousness is markedly different from normal waking experience; can be more or less organized.
    • Hypnosis: an interaction where the person responds to the hypnotist's suggestions; post-hypnotic suggestions can be given for future behavior.
  • Post-hypnotic suggestions: instructions given during hypnosis that affect behavior after coming out of hypnosis (e.g., bark like a dog); often the person does not recall these post-hypnotic suggestions.
  • Common therapeutic uses: smoking cessation, weight loss, pain management, trauma processing.
  • Hypnotizability: individuals vary in susceptibility; people who are highly suggestible tend to be more affected by hypnosis.
  • Anecdotal classroom stories:
    • A student volunteer at a hypnotist show and others observing relaxation; some participants later show signs of altered awareness.
    • In another class, a parent’s interest in hypnosis was mentioned; volunteers may be asked whether they want to prove the hypnotist wrong.
  • The two main theories of hypnosis:
    • Sociocognitive theory: hypnosis is not an ASC; people are merely playing the part and following the hypnotist’s directives due to social cues and expectancy.
    • Dissociation theory: hypnosis involves a genuine ASC in which conscious awareness becomes dissociated from other aspects of consciousness.
  • Empirical stance: there is evidence supporting both theories; most people lean toward sociocognitive explanations, but there is support for dissociation as well.
  • Common questions: what hypnosis is best used for? The most robust evidence supports hypnotic analgesia for pain management (acute and chronic) and in recovery from surgery; less clear evidence for other uses.
  • Classic replication-style example: people in a cold-water task show differential arm-in-water tolerance when hypnotized, supporting dissociation for pain control.
  • Illustrative case questions in class:
    • A hypothetical scenario with a hypnotist asking a person to crow like a rooster; observers interpret the relaxed state as evidence of altered awareness, illustrating the debate between theories.
    • A birthday party scenario with kids acting like animals under hypnosis; the sociocognitive view would say they’re behaving because they think they should, not because they’re in an ASC.
  • Key takeaway: hypnosis is a tool with strong evidence for certain benefits (notably analgesia), but the ASC claim remains debated; most researchers favor sociocognitive explanations, while some findings support dissociation.

Meditation

  • What is meditation? A practice of intense contemplation that leads to calmness and can be described as an ASC.
  • Cultural context:
    • In eastern traditions (Hinduism, Buddhism, Sikhism), meditation is often embedded in religious practice.
    • In Western contexts, meditation is frequently pursued for relaxation and stress relief, sometimes secularized.
  • Three main types of meditation:
    • Concentrated meditation: focus attention on one object (breathing pattern, mental image, or a phrase such as a mantram like Om).
    • Mindfulness meditation: monitor thoughts nonjudgmentally as they flow; attention to thoughts without reacting or judging.
    • Transcendental meditation: prolonged, concentrated practice (e.g., ~20\ \text{minutes} per day) to reach deeper states of calm.
  • Health benefits and evidence:
    • Transcendental meditation has been associated with improvements in cardiovascular health markers in some randomized studies.
    • Example: a 2006 study where heart patients were assigned to a treatment group practicing transcendental meditation for 20\ \text{minutes} daily; after 16\ \text{weeks}, treatment group showed greater improvements in blood pressure and cholesterol than controls.
    • However, the study does not clearly identify which aspect of practice caused the benefits (relaxation vs ASC changes), leaving ambiguity about mechanism.
  • Brain and health considerations:
    • Some research suggests meditation may alter brain structure or slow gray-matter decline; yet correlation does not imply causation.
    • Potential confounding variables include overall lifestyle, stress levels, exercise, diet, and other self-care activities.
  • Critical discussion:
    • It’s important to distinguish between correlation and causation when linking meditation to health outcomes.
    • Different forms of meditation may have distinct effects; studies often aggregate various practices.
  • Practical implications:
    • Meditation is linked to enhanced self-awareness and self-regulation; benefits extend beyond cognition to emotional well-being.
    • When evaluating studies, consider confounds such as lifestyle, baseline health, and adherence to practice.

Flow

  • Definition:
    • Flow is a highly focused, altered state of consciousness characterized by diminished awareness of time and self due to complete absorption in an enjoyable activity.
  • How it feels and looks:
    • People report being “locked in,” fully present, and deeply engaged with the task.
    • Common contexts: intense sports, high-skill performances, or immersive religious ceremonies.
  • Distinction from hypnosis/meditation:
    • Unlike hypnosis, flow arises from immersion in an activity rather than following external suggestions.
    • Unlike some forms of meditation, flow is characterized by deep engagement rather than detachment from the self.
  • Significance:
    • Flow illustrates how attention and immersion can alter consciousness and subjective experience without external regulation.

Drugs and consciousness

  • Broad concept: psychoactive drugs are mind-altering substances that change brain neurochemistry by activating certain neurotransmitters.
  • Four major classes:
    • Stimulants: increase behavioral and mental activity; neurotransmitters affected include dopamine and norepinephrine (adrenaline).
    • Depressants: decrease nervous system activity; commonly act via GABAergic systems; examples include alcohol.
    • Opioids: produce analgesia and euphoria; reduce pain; examples include heroin and morphine.
    • Hallucinogens: alter perception and thought; examples include LSD, psilocybin mushrooms, MDMA, and marijuana in varying degrees.
  • Stimulants (examples and mechanisms):
    • Examples: caffeine, Adderall, cocaine, methamphetamine.
    • Effects: heightened arousal, increased wakefulness, enhanced focus (in some contexts).
    • Neurochemistry: increases in dopamine and norepinephrine signaling.
    • Notable data point: methamphetamine is associated with structural brain damage, particularly in the frontal lobes. A composite brain-imaging example used in class compared pre- and post-use scans to illustrate damage in a case involving a non-regular user who became addicted.
  • Depressants (examples and mechanisms):
    • Examples: alcohol (ethanol) and anti-anxiety medications.
    • Effects: decreased nervous system activity, sedation, memory impairment (blackouts) at high doses.
    • Neurochemistry: GABAergic inhibition is enhanced; dopamine release can be affected indirectly.
    • Societal impact: alcohol is the most widely used depressant; associated with substantial public health costs (e.g., estimated at \$100\,{,}000{,}000{,}000 annually in the U.S. due to healthcare costs and lost productivity).
    • Behavioral effects: lowered inhibitions, risk-taking, drunk driving, and abuse.
    • Moderating factors: the experience with alcohol is not only the pharmacology but also expectations and social context.
  • Opioids (examples and effects):
    • Examples: heroin, morphine.
    • Effects: strong analgesia, euphoria, sedation, and high risk of dependence.
    • Uses: historically used to relieve severe pain, with palliative care in terminal illnesses.
  • Hallucinogens (examples and effects):
    • Examples: MDMA (ecstasy), LSD, psilocybin (magic mushrooms), cannabis (marijuana).
    • Effects: alter sensations, thoughts, and emotions; can evoke sensory images without external input.
    • Contemporary notes: microdosing (taking sub-perceptual doses) under professional guidance is being explored as a therapeutic approach for some anxiety and mood disorders; some reports suggest potential benefits, though evidence remains mixed and controversial.
  • Moderating factors and context:
    • Expectancies and social context strongly influence drug experience (placebo-like effects and cultural norms).
    • Male-female differences: in the context of alcohol, men are roughly twice as likely to report binge drinking as women.
  • Practical considerations and risks:
    • Long-term use can cause cognitive and structural brain changes (e.g., stimulant-related neurotoxicity, meth-related frontal lobe damage).
    • Economic and social costs of widespread use (e.g., alcohol-related harms and public health burdens).
    • The line between therapeutic use (e.g., certain psychoactive-guided therapies) and recreational misuse raises ethical questions about access, consent, and safety.

Connections, implications, and synthesis

  • Concepts of consciousness:
    • Hypnosis, meditation, and flow illustrate that altered or focused mental states can arise via different pathways: social-cognitive expectancy, contemplative practice, and deep task immersion.
    • Drugs demonstrate how neurochemical changes translate into altered perception, mood, and behavior.
  • Methodological cautions:
    • Distinguishing correlation from causation (e.g., meditation and health outcomes) requires careful control of confounding variables such as lifestyle and other self-care practices.
    • The interpretation of ASC evidence requires distinguishing subjective reports from objective measures (neuroimaging, physiological markers).
  • Ethical and practical implications:
    • Hypnosis and post-hypnotic suggestions raise ethical questions about consent, autonomy, and potential manipulation.
    • Microdosing and guided hallucinogen therapies prompt debates about medical oversight, safety, and regulatory status.
    • Understanding the role of expectancy in drug experiences underscores the social dimension of pharmacology and the importance of education about real vs. perceived effects.
  • Foundational links:
    • These topics connect to broader principles of psychology and neuroscience: perception, memory, attention, learning, neurochemistry, and the social-contextual determinants of behavior.

Summary of numerical and explicit references (for quick review)

  • Post-hypnotic suggestions: a tool used by hypnotists to induce future behaviors (e.g., barking like a dog).
  • Induction phrases: typical approach begins with statements like "\text{you are getting sleepy}" and "\text{your arms are getting heavy}".
  • Transcendental meditation study: duration 20\ \text{minutes} per day; duration of study: 16\ \text{weeks}; outcome: improved cardiovascular markers relative to control.
  • Brain imaging example for meth use: 29 brain scans were combined to illustrate damage; red/yellow areas indicate frontal-lobe damage; a case described where damage appeared within less than 3\ \text{years}.
  • Alcohol economic impact: estimated annual cost in the U.S. in the order of \$100{,}000{,}000{,}000.
  • Gender difference: men are roughly 2\times more likely to report binge drinking than women.
  • Flow descriptions: an example is immersion in intense sports or religious ceremonies; alternately, notes on immersive experiences such as music or instrument play (theoretical context of flow).
