    Study Notes

    Variations in Consciousness - Key Concepts and Terms

    • Consciousness is awareness of internal and external stimuli; a subjective experience with varying levels of awareness.
    • William James coined the term "stream of consciousness."
    • Electroencephalograph (EEG) measures electrical brain activity (brain waves) via electrodes on the scalp.
    • Brain waves vary in amplitude and frequency (e.g., beta waves for awake/alert, delta waves for deep sleep).
    • Circadian rhythms are daily cyclical variations in biological processes, governed by a 24-hour internal clock.
    • The suprachiasmatic nucleus (SCN) in the hypothalamus regulates the sleep-wake cycle and melatonin secretion by the pineal gland, in response to light.
    • Ignoring circadian rhythms affects sleep quality and can cause jet lag. Adjusting to time zone changes is easier with westward travel.
    • Sleep deprivation/restriction impairs attention, reaction time, cognition, motor skills, and decision-making.

    Stages of the Sleep-Wake Cycle

    • Sleep stages, from stages 1 to 4, represent decreasing alertness, and increasing slow wave sleep.
    • Stage 1 is a brief transitional stage with decreasing physiological activity.
    • Stage 2 involves brief bursts of higher-frequency brain waves.
    • Stages 3 and 4 are slow-wave sleep, characterized by high-amplitude, low-frequency delta waves.
    • REM sleep (stage 5) is characterized by rapid eye movements, vivid dreaming, high-frequency/low amplitude brain waves. It's important for memory consolidation and emotional processing.
    • Sleep stages 1-4 are often referred to as non-REM sleep.

    Sleep Disorders

    • Insomnia is chronic difficulty sleeping, affecting nearly one-third of adults. Symptoms include difficulty falling/staying asleep, early-morning awakenings.
    • Narcolepsy involves sudden, irresistible sleep attacks during normal waking periods.
    • Sleep apnea is a condition where breathing stops and restarts repeatedly during sleep.
    • Nightmares and night terrors are anxiety-inducing dreams. Night terrors usually involve abrupt awakenings from non-REM sleep.
    • Somnambulism (sleepwalking) happens during stages 1-2.
    • REM sleep behavior disorder (RBD) occurs during REM sleep, with the person acting out their dreams.

    Theories of Hypnosis

    • Social-cognitive theory: Hypnosis is a result of normal factors like expectation and suggestion.
    • Altered-state theory: Hypnosis is a unique state of consciousness different from normal wakefulness and sleep.

    Effects of sleep restriction/deprivation

    • Sleep restriction/deprivation impairs attention, reaction time, cognition speed, accuracy, motor coordination, and decision-making.
    • Causes an increase in transportation accidents and mishaps in the workplace.
    • Increases health care costs, costing the economy billions of dollars.

    Dream Theories

    • Freud's wish fulfillment theory: Dreams fulfill ungratified needs.
    • Problem-solving, activation-synthesis, and other dream theories exist.

    Types of Psychoactive Drugs

    • Narcotics (e.g., heroin, morphine) alleviate pain, but have high physical and psychological dependence potential.
    • Sedatives (e.g., benzodiazepines) reduce CNS activation, common side effects include drowsiness and sluggishness, and are highly addictive.
    • Stimulants (e.g., caffeine, nicotine, cocaine) increase CNS activation and behavioral activity, with various dependence risks.
    • Hallucinogens (e.g., LSD) cause distortions in sensory perception.

    Tolerance and Dependence

    • Tolerance is a decreased responsiveness to a drug over time, requiring larger doses for the same effect.
    • Dependence is a state where the person needs the drug to avoid withdrawal symptoms or satisfy intense cravings, a serious issue.

    Alcohol and Other Drugs

    • Alcohol is the most commonly used recreational drug, with moderate dependence.
    • MDMA (ecstasy) is a compound drug related to amphetamines and hallucinogens, and was at its height of popularity in the 1990s.
    • Cannabis (marijuana) contains THC and has low to moderate dependence potential
