Prologue to Chapter 5: States of Consciousness
  • Life is made up of many kinds of conscious awareness
  • Who/what is perceiving this particular stimulus here, now?
  • When you say, “I am” what are you referring to? Who is the “you?” What is the “you” you are talking about?
  • What is consciousness?

What is consciousness?

Psych 101 Chapter 5

wide awake normal waking consciousness
Wide Awake: Normal waking consciousness
  • Three varieties of normal waking consciousness
    • directed consciousness
    • flowing consciousness
    • daydreaming
  • Directed consciousness
    • a focused and orderly “one tracked” awareness
    • centered on a specific stimulus

Psych 101 Chapter 5

normal waking consciousness
Normal waking consciousness
  • Flowing consciousness
    • a drifting, unfocused awareness
    • your awareness (attention) moves at random from attention to one stimulus to another
  • Daydreams
    • focused and directed thinking, like directed consciousness, but these involve fantasies (and not stimuli immediately at hand)

Daydreams

Psych 101 Chapter 5

normal waking consciousness6
Normal waking consciousness
  • Divided consciousness: Being two places (mentally) at the same time
    • the process of “splitting off” two or more conscious activities that occur simultaneously
    • similar to “multi-tasking” that can be done by computers
    • for example: rub your head and pat your stomach or divide 81 by 3 while saying the “Pledge of Allegiance”

Psych 101 Chapter 5

normal waking consciousness7
Normal waking consciousness
  • The concept of the “Unconscious Mind”
    • the notion of an unconscious mind helps to explain mental processes that occur without conscious awareness
    • for example: when you forget something and then, hours later, suddenly remember it though you had not been consciously trying to remember it
    • the “Unconscious Mind” is a big part of the Psychoanalytic school of thought in psychology

Psych 101 Chapter 5

sleeping and dreaming consciousness while asleep
Sleeping and dreaming: Consciousness while asleep
  • Stages of sleep
    • involves passing from waking state into a semi-wakeful state, then into 4 stages of progressively deeper sleep
    • Hypnagogic State
      • a twilight state that is neither daydreaming or sleeping that occurs as you begin to fall asleep but are not yet sleeping
      • unusual things can happen in the hypnagogic state

Psych 101 Chapter 5

sleeping and dreaming
Sleeping and dreaming
  • States of light and deep sleep
    • 4 stages of sleep based on EEG measures of brainwave activity during sleep that reveal different brain-wave patterns in sleep
    • Stage 1 sleep: shifting from beta-to-alpha wave brain activity patterns; the brain is slowing down
    • Stage 2 sleep: alpha-to-theta brain wave patterns; the brain is slowing further

Psych 101 Chapter 5

sleeping and dreaming10
Sleeping and dreaming
  • States of light and deep sleep
    • Stage 3 sleep: theta-to-delta brain wave patterns; the brain is slowing further
    • Stage 4 sleep: delta wave brain patterns; the brain is at its slowest
  • Dream Sleep
    • Emergent sleep: the brain begins to move faster; returns to beta wave pattern of wakefulness though you are still asleep

Psych 101 Chapter 5

sleeping and dreaming11
Sleeping and dreaming
  • Dream Sleep
    • Beta-wave brain activity is present and REM (rapid eye movement) activity is present
    • most people generally dream more than once in a single night; virtually everyone dreams every night
  • The reoccuring sleep cycle moves from beta-alpha-theta-delta-beta in the course of about 1.5 hours

Psych 101 Chapter 5

sleeping and dreaming12
Sleeping and dreaming
  • The normal sleep required by individuals is 7.5 hours per night; a typical sleep cycle is about 1.5 hours long so the typical person has 4 to 5 sleep cycles occurring per sleep period
  • The normal person may have as much as 1 to 2 hours of dreaming every night

Psych 101 Chapter 5

sleeping and dreaming13
Sleeping and dreaming
  • Why do we sleep and dream?
    • What good is it to sleep and dream anyway? Isn’t it a waste of about 33% of your life?
      • NO! Sleep and dreaming is important to maintain normal psychological functioning
      • Sleep deprivation studies show that going more than 40 hours without sleep begins to tell by the appearance of forgetting, irritation, poor judgment, and other symptoms

Psych 101 Chapter 5

sleeping and dreaming14
Sleeping and dreaming
  • Extreme sleep deprivation
    • studies of extreme sleep deprivation have shown that at about 120 hours of sleep deprivation individuals will begin to behave in ways indistinguishable from paranoid schizophrenics
    • these symptoms include: hostility, suspicion, paranoia, unpredictable behavior, halucinations and delusions

Psych 101 Chapter 5

sleeping and dreaming15
Sleeping and dreaming
  • What important thing happens in sleep?
    • Studies on sleep and REM deprivation show that it is the REM (dreaming state) of sleep that is the KEY reason why we sleep; sleeping without dreaming is not useful in the big picture
    • We do, like Shakespeare said, “sleep, perchance to dream…”

Psych 101 Chapter 5

sleeping and dreaming16
Sleeping and dreaming
  • The Content and Meaning of Dreams
    • Freud’s view of dreams
      • Dreams have “manifest” content
      • Dreams have “latent” content
      • Dreams provide information from the unconscious mind that a person can use to understand themselves
    • Dream interpretation
      • We’ll do some dream interpretation now so you can decide for yourself if Freud was right

sleeping and dreaming20
Sleeping and dreaming
  • Nightmares and other sleep phenomena
    • Night Terrors
      • very frightening event typically in children where they scream out in the night and cannot be easily awakened by a concerned parent
      • typically these are outgrown as the child gets older
      • they are not typically a “sign” of emotional problems in the child; rather it is likely that they are due to cognitive physical immaturity

Psych 101 Chapter 5

sleeping and dreaming21
Sleeping and dreaming
  • Nightmares and other sleep phenomena
    • Sleepwalking and sleeptalking
      • typically occur in Stage 4 sleep (not in REM sleep)
      • about 15% of the population has experienced these phenomena
      • the sleeper should be protected from hurting themself; individuals have been known to leave their home driving their car while asleep
      • there is no truth to the wive’s tale that the sleepwalker should not be awakened

Psych 101 Chapter 5

sleeping and dreaming22
Sleeping and dreaming
  • Sleep disorders
    • Insomnia: affects about 20 million Americans
    • Narcolepsy: a form of epilepsy that causes sudden, immediate sleeping
    • Sleep apnea: cessation of breathing while sleeping; associated with the very loud snoring person
    • Incubus/Succubus attacks

Sleeping and dreaming
  • Sleep is one of the cycles that the body does daily. These cycles are called “circadian rhythms” and the body typically operates on a cycle of about 24 hours. Other circadian body cycles include:
    • body temperature
    • urine production
    • metabolism

altered states of consciousness
Altered states of consciousness
  • Altered states involve several common characteristics:
    • Distortions of perception
    • Intense emotions (positive or negative)
    • A sense of “unity”
    • Altered states are often illogical, indescribable, and transcendent; they may involve a sense of “self-evident” reality

Psych 101 Chapter 5

altered states
Altered states
  • Meditation can produce an altered state of consciousness
    • extreme focused concentration away from thoughts and feelings
    • generates a sense of relaxation
    • focusing on not thinking; try to stop thinking and see if you can do it
    • use of mantras, koens, praying, or other techniques may be useful in meditating

Psych 101 Chapter 5

altered states27
Altered states
  • Hypnosis can produce an altered state of consciousness
    • characterized by relaxation, hypnotic halucinations, hypnotic analgesia, age regression, and hypnotic control
    • is hypnotism real, fake, or role playing?
    • about 15% of the population is easily hypnotized

Psych 101 Chapter 5

altered states28
Altered states
  • History of hypnotism
    • Anton Mesmer and Mesmerism
      • his use of “magnetic waters”, magical incantations, and showmanship as “treatment” of psychological/medical problems
      • was a hit in France in the 1790s
    • Freud became interested in it for a time but later rejected it as nonsense
    • Picked up by American behaviorists in the US in the 1930s; still used in the US today

Psych 101 Chapter 5

altered states29
Altered states
  • Applications of hypnotism
    • used (with varying results) to help people:
      • stop smoking
      • stop drinking
      • stop eating
    • has been used to induce anesthesia in certain individuals, e.g., drug-free childbirth; there have been surgeries carried out with the patient only under hypnotic suggestion for pain control

Psych 101 Chapter 5

altered states30
Altered states
  • Another altered state is “depersonalization”
    • the perceptual experience of one’s body or surroundings becoming distorted or unreal in some way
    • a sense of being out of one’s body or that one’s body has no limit; this experience can happen to individuals on an LSD trip
    • can be very frightening; a bad trip

Psych 101 Chapter 5

altered states31
Altered states
  • Yet another altered state is the “Near Death Experience”
    • experienced by individuals clinically dead during surgery or accident who can return to tell about it
    • similarity of reports of NDE
    • is it real or is it something else?
    • heaven/hell or just neurochemistry at work?

altering consciousness with drugs
Altering consciousness with drugs
  • Drug use: some basic considerations
    • Individuals have variable responses to drugs
      • many factors influence how a person reacts to drugs, e.g., dosage, purity of a drug, a person’s expectations surrounding use of a given drug, a person’s characteristics/personality, as well as a person’s mood
      • one must consider the drug to be taken and the person taking a drug when considering the effect of any given drug

Psych 101 Chapter 5

altering consciousness
Altering consciousness
  • Drug use: some basic considerations
    • Problems associated with drug use
      • some drugs can cause physical dependency, e.g., cocaine, heroin
      • some drugs can cause psychological dependency, e.g., marijuana
      • physiological addiction to a drug is a huge price to pay for experiencing a drug’s effects
      • drugs are generally a stupid way of inducing altered states because you can do it without using drugs

Psych 101 Chapter 5

altering consciousness36
Altering consciousness
  • Psychotropic drugs: Drugs that will induce altered states
    • Stimulants: amphetamines, cocaine, caffeine, and nicotine

altering consciousness37
Altering consciousness
  • Psychotropic drugs
    • Halucinogens: mescaline, hashish, marijuana, peyote, psilocybin

  • Use alternate ways to induce altered states, e.g., meditation, fasting, prayer, etc.

Psych 101 Chapter 5

application of psychology
Application of psychology
  • The legal consciousness-altering drugs
    • alcohol is the widest-used drug that alters persons’ consciousness
