    Study Notes

    Consciousness

    • Consciousness is awareness of sensations, thoughts, and feelings at a given moment.
    • Waking consciousness is being awake and aware of thoughts, emotions, and perceptions.
    • Altered states of consciousness include sleeping, dreaming, drug use, and hypnosis.
    • Historically, psychologists were hesitant to study consciousness due to its subjectivity.
    • Now, scientific approaches like measuring brain wave patterns are used.
    • Consciousness may arise from increased neuronal activity or specific neuron/pathway activation.

    Stages of Sleep

    • Sleep is a complex process with distinct stages.
    • Stages cycle roughly every 90 minutes, moving between wakefulness, light sleep, deep sleep, and REM sleep.
    • Stage 1: Transition between wakefulness and sleep, featuring rapid, low-amplitude brain waves (lasts a few minutes).
    • Stage 2: Sleep deepens, brain activity slows into a more regular wave pattern. "Sleep spindles" are brief bursts of spiky, high-amplitude brain waves. About half of young adult sleep is stage 2.
    • Stage 3: Deepest stage of sleep, with slow brain waves, high peaks, and low valleys. Least responsive to external stimuli; dominates the first half of the night.
    • REM Sleep: Occurs during the second half of the night. Characterized by rapid eye movements, fast brain wave patterns similar to wakefulness, and vivid dreaming.

    REM Sleep: The Paradox of Sleep

    • REM sleep is crucial for learning, memory consolidation, and emotional processing.
    • It's a restorative period, reviewing daily experiences.
    • People cycle through these stages nightly, with sleep stage duration altering according to the night cycle.
    • REM sleep is most frequent during the later part of the night and lasts about 20% of the night.
    • Cycle time is roughly 90-minute intervals throughout the night
    • Nighttime sleep stages (especially stage 3) are often most critical for physical wellness and the body's restorative functions.
    • Throughout the night, the types of brain activity and other physiological responses change.

    The Function and Meaning of Dreaming

    • Nightmares are frightening dreams that are related to anxieties, fears, and experiences from the day.
    • Common elements in dreams are frightening scenarios, such as being chased by an attacker.
    • Daydreams are vivid fantasies constructed during wakefulness.
    • They often involve scenarios of both positive and negative outcomes, not unlike waking thoughts, but they don't require a separate neurological state.
    • Theories suggest that dreams and daydreaming provide insights into emotional states, mental processes, and possible anxieties or unconscious concerns.

    Sleep Disturbances

    • Insomnia, sleep apnea, and night terrors are sleep disturbances.
    • Insomnia is trouble falling asleep or staying asleep and is common in older adults, depressed individuals or those experiencing acute stress.
    • Sleep apnea leads to intermittent breathing cessation during sleep, impacting sleep quality.
    • Night terrors are sudden awakenings with intense fear.

    Circadian Rhythms

    • Internal rhythms influence various bodily functions, including sleep-wake cycles.
    • Circadian rhythms are roughly 24 hours long.
    • Regulated by the brain's suprachiasmatic nucleus (SCN).
    • Light and darkness influence the circadian rhythm.
    • Sleepiness is often felt in the afternoon, regardless of a heavy meal and affected by other factors.
    • This roughly 24-hour sleep-wake period is affected by age, personal factors, and lifestyle choices.

    Daydreams/Waking Dreams

    • Daydreams are vivid fantasies that people create while awake.
    • They are generally scenarios of both positive and negative outcomes that focus on personal desires and anxieties.
    • While daydreams are not random, their content often reflects individuals' anxieties, personal concerns, and experiences from the day.
    • Daydreams are more coherent than sleep dreams—individuals are still aware of their environments.

    Hypnosis

    • Hypnosis is a trance-like state involving heightened suggestibility.
    • Susceptibility to hypnosis varies.
    • Several theories exist on whether hypnosis is a distinct state or a type of altered consciousness, with varying levels of awareness.
    • Some view hypnosis as a state of divided consciousness, while others see it as a continuum of normal consciousness.

    Meditation

    • Meditation is a technique to refocus attention, often by repeating a mantra.
    • Leads to biological changes, including lower heart rate and blood pressure, and altered brainwave patterns.

    Psychoactive Drugs

    • Psychoactive drugs influence emotions, perceptions, and behavior by affecting the nervous system.
    • Addictive drugs create biological or psychological dependence.
    • Stimulants increase arousal (e.g., caffeine, nicotine, amphetamines, cocaine).
    • Depressants slow down the nervous system (e.g., alcohol, barbiturates).
    • Narcotics/opioids relieve pain and anxiety (e.g., heroin, morphine, opioids).
    • Hallucinogens alter perception and thoughts (e.g., marijuana, MDMA, LSD).
