What are some states of consciousness that you’ve
experienced?
![Page 5: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/5.jpg)
Some Early Definitions of consciousness
• Consciousness: All the sensations, perceptions, memories, and feelings you are aware of in any instant.
• Your sense of yourself.– Waking Consciousness: Normal, clear,
organized, alert awareness
– Altered State of Consciousness (ASC): Awareness that is distinctly different in quality or pattern from waking consciousness• Drug induced states, illness, sleep,
hypnosis

2)
3)
– Set a goal that will improve your life.– Think of patterns you’d like to break or habits you’d
like to acquire…. What would you like to start DOING?
– This should be your SEED or FOCUS for self hypnosis, meditation or sleep processing.

2) Decide on a method to achieve it.
• Self hypnosis• Sleep/dream processing power• Meditation• NLP• Other (research!)
![Page 12: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/12.jpg)
3) Determine a method to assess success. Was goal achieved?
• Test• Journal• Survey of others in your life• Performance on task related to goal• Many others methods…
![Page 13: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/13.jpg)
4) Summary piece – Art, Powerpoint, Research paper, or other format

cut outs, anything related to this project• Exhibition piece!• You will present to class, POL style• You will be graded by class and me
![Page 14: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/14.jpg)
Today…
• Define a PERSONAL GOAL (specific, positive, attainable)
• Think about and document your negative patterns associated with that goal and how you might change them
• Conduct preliminary research on methods to achieve your goal, write key points
![Page 15: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/15.jpg)
Hypnosis• Altered state of consciousness characterized
by intense relaxation, narrowed attention and increased openness to suggestion– Mesmer: Believed he could cure diseases by
passing magnets over body; true “animal magnetism” (“mesmerize” means to hypnotize)
– Must cooperate to become hypnotized– You pass through hypnosis every time you
fall asleep and return to waking state
![Page 16: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/16.jpg)
Hypnosis Can
• Help people relax• Reduce pain• Get people to make better progress in
therapy• Allow people to achieve goals, such as not
smoking, being more confident, losing weight, improving memory…
![Page 17: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/17.jpg)
Hypnosis Cannot
• Produce acts of superhuman strength• Force you to do things against your will
![Page 18: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/18.jpg)
Goal of hypnosis
• Quiet the conscious mind• Shut up the noise• Get rid of mental clutter• Stop judgment… in order to• Access the vast processing potential of the
SUBCONSCIOUS mind
![Page 19: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/19.jpg)
![Page 20: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/20.jpg)
![Page 21: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/21.jpg)
3 phases to hypnotic process
• Induction• Suggestion implanted in subconscious (while
“under”)• Return to waking state
![Page 22: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/22.jpg)
![Page 23: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/23.jpg)
• Hypnosis starts with INDUCTION: subject listens and relaxes. Shuts off conscious mind.
– Ex: listens to alphabet backwards
– Ex: Imagines relaxing liquid flowing though body, part by part
• hypnotist guides you into deep trance by asking you to focus on relaxing your body and breathing
• Subject must realise that they are being hypnotised. It is a VOLUNTARY process.
• It is NOT possible for someone to be hypnotised against their will.
![Page 24: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/24.jpg)
Once the subconscious is accessed, hypnotist implants SUGGESTIONS
Ex: You will find cigarettes disgustingEx: You will find that you want to smile
and hold your posture confidently at parties
Ex: You will remember an event that happened a long time ago and revisit associated emotions (ex abuse)
![Page 25: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/25.jpg)
• People differ in how susceptible they are to hypnotic suggestions.
• This can be measured by hypnotic susceptibility scales.
![Page 26: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/26.jpg)
Sample test items from the Stanford Hypnotic Susceptibility
Scale, Form C
Item Suggested Behaviour
Criterion for Passing
Arm lowering Right arm will become heavy
Arm lowered by at least 6 inches
Moving hands apart Force is pushing hands apart
Hands are 6 or more inches apart
Mosquito hallucination
Mosquito is buzzing nearby
Any grimace or acknowledgement
Posthypnotic amnesia
Will not remember suggestions
Three or fewer items recalled
![Page 27: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/27.jpg)
Hypnotic Susceptibility
• According to Hilgard (1977), in an average testing session – 10% of subjects will be completely
nonresponsive, – 10% will pass all or nearly all items, – and the rest will fall in between.
• Susceptibility can be enhanced by increasing people’s expectations (Spanos et al., 1991; Vickery & Kirsch, 1991).
![Page 28: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/28.jpg)
Behavior under Hypnosis
• Hypnotised people are very suggestible and their behaviour will conform with what the hypnotist tells them. Typical behaviour that can be induced include:
• Acting out imaginary scenes.• Pretending to be an animal.• Believing a limb cannot move or is insensitive
to pain.• Positive and negative hallucinations – seeing
things that are not really there, or not seeing objects that really are present.
![Page 29: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/29.jpg)
• Posthypnotic suggestibility – a subject is given instructions under hypnosis and follows them after returning to a non-hypnotised state.
• Posthypnotic amnesia – the subject is instructed to not remember any of the suggested behaviour after leaving the hypnotic state.
![Page 30: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/30.jpg)
Hypnosis and changes in perception
• Does hypnosis really change a person’s perception during positive and negative hallucinations?
• Miller et al. (1973) tested this hypothesis using the Ponzo illusion.
![Page 31: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/31.jpg)
The Ponzo Illusion
![Page 32: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/32.jpg)
Hidden Observer
• Detached part of hypnotized person’s awareness that silently observes events
![Page 33: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/33.jpg)
Stage Hypnosis
• Simulation of hypnotic effects
![Page 34: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/34.jpg)
Tricks of the Trade
• Waking Suggestibility: People on stage do not want to spoil the act, so they will follow any instruction.
• Selection of Responsive Subjects: Any “volunteer” who does not get hypnotized in the stage group and does not follow instructions is “voted off.”
• The Hypnosis Label Disinhibits: On stage, once you are “in a hypnotic trance,” your responsibility for actions is removed; you can do whatever you want!
![Page 35: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/35.jpg)
More Stage Hypnosis “Tricks of the Trade”
• Hypnotist as Director: Once they are in a trance, the “volunteers” are suddenly the show’s stars, and they will act like it. The hypnotists only need to direct them.
• Stage Hypnotists Use Tricks: Stage hypnosis is 50% deception and 50% taking advantage of the situation
![Page 36: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/36.jpg)
More Hypnosis Concepts
• Hypnotic Susceptibility: How easily a person can be hypnotized
• Basic Suggestion Effect: Tendency of hypnotized people to carry out suggested actions as though they were involuntary
![Page 37: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/37.jpg)
Meditation
• Mental exercise designed to produce relaxation or heightened awareness
• Concentrative Meditation: Attention is paid to a single focal point (i.e., object, thought, etc.)– Produces relaxation response and thus
works to reduce stress• Mindfulness Meditation: Based on widening
attention span to become aware of everything experienced at a given moment
• Mantra: Word(s) or sound(s) repeated during concentrative meditation
![Page 38: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/38.jpg)
Relaxation Response
• Occurs at time of relaxation; internal response that prevents activation of adrenal glands
![Page 39: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/39.jpg)
Drugs and Altered States of Consciousness
• Psychoactive Drug: Substance capable of altering attention, judgment, memory, time sense, self-control, emotion, or perception
• Stimulant: Substance that increases activity in body and nervous system
• Depressant: Substance that decreases activity in body and nervous system
![Page 40: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/40.jpg)

Physical Dependence
• Physical Addiction based on drug tolerance and withdrawal symptoms– Drug Tolerance: Reduction in body’s
response to a drug– Withdrawal Symptoms: Physical illness
following withdrawal of the drug
![Page 42: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/42.jpg)
Psychological Dependence
• Drug dependence based on psychological or emotional needs– Usually crave drug– Can be as powerful as physiological
addiction
![Page 43: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/43.jpg)
Stimulants (Uppers)
• Amphetamines: Synthetic stimulants that excite the nervous system– Dexedrine and Methamphetamine are two
types of stimulants• Amphetamine Psychosis: Loss of contact with
reality because of amphetamine use; user tends to have paranoid delusions
![Page 44: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/44.jpg)
Cocaine
• Central Nervous System stimulant derived from leaves of coca plant; also used as local anesthetic– From 1886-1906, Coca-Cola did indeed
have cocaine in it!– Highly addictive drug– Anhedonia (Inability to Feel Pleasure):
Common after cocaine withdrawal
![Page 45: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/45.jpg)
MDMA (Ecstasy)
• Chemically similar to amphetamine; created by small variations in a drug’s structure– Risks of using MDMA are unclear– May cause severe liver damage – Repeated use damages serotonergic brain
cells
![Page 46: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/46.jpg)
Caffeine
• Most frequently used psychoactive drug in North America; present in colas, chocolate, coffee, and tea
• Causes hand tremors, sweating, talkativeness, tinnitus, suppresses fatigue or sleepiness, increases alertness– May be hazardous to pregnant women if
used excessively
![Page 47: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/47.jpg)

Nicotine
• Natural stimulant found mainly in tobacco; known carcinogen
• May cause stomach pain, vomiting, diarrhea, confusion, tremors
• Addictive• Sum: Don’t smoke; smoking kills (so does
chewing tobacco)
![Page 50: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/50.jpg)
Sedatives: Barbiturates
• Sedative drugs that depress brain activity– Seconal and Amytal are two types– Easy to overdose
![Page 51: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/51.jpg)
GHB (Gamma-Hydroxybutyrate)
• Central Nervous System (CNS) depressant that relaxes and sedates; combination of degreasing solvent and drain cleaner– Sedative effects may result in nausea, loss
of muscle control, and either sleep or a loss of consciousness
– Inhibits gag reflex, so some choke to death on their own vomit
– Addictive and deadly
![Page 52: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/52.jpg)
Sedatives: Tranquilizers
• Lower anxiety and reduce tension– Valium, Xanax, and Librium are three types– Rohypnol: Related to Valium; lowers
inhibitions and produces relaxation or intoxication. Larger doses can induce short-term amnesia and sleep• Date rape drug because it’s odorless
and tasteless• Drug Interaction: One drug increases the
effect of another
![Page 53: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/53.jpg)
Alcohol
• Ethyl Alcohol: Intoxicating element in fermented and distilled liquors– Not a stimulant but does lower inhibitions– Depressant
• Binge Drinking: Consuming five or more drinks in a short time; four or more for women– Serious sign of alcohol abuse

Detoxification
• Withdrawal of the person from alcohol• Occurs in a medical setting and is tightly
controlled• Often necessary before long-term treatment
begins

Some Hallucinogens
• Hallucinogen: Substance that alters or distorts sensory impressions
• Lysergic Acid Diethylamide (LSD): Hallucinogen that can produce hallucinations and other psychotic symptoms
• Mescaline (Peyote) and Psilocybin (Magic Mushrooms)
• PCP (Angel Dust): Initially can have hallucinogenic effects; also an anesthetic and has stimulant and depressant effects

Marijuana
• Leaves and flowers of the hemp plant– Active chemical: THC– Effects: Relaxation, time distortion,
perceptual distortions

Some Health Risks of Using Marijuana
• Increases risk of a variety of cancers, including prostate and cervical cancer
• Can suppress immune system, perhaps increasing risk of disease
• Activity levels in the cerebellum are lower than normal in pot users
• Pot may damage some of the brain’s memory centers

Sleep
• Innate, biological rhythm• Microsleep: Brief shift in brain-wave patterns
similar to those of sleep• Sleep Deprivation: Sleep loss; being deprived
of needed amounts of sleep• Sleep-Deprivation Psychosis: Major
disruption of mental and emotional functioning that occurs because of sleep loss
• Hypersomnia: Excessive daytime sleepiness

Measuring Sleep Changes
• Electroencephalograph (EEG): Brain-wave machine; amplifies and records electrical activity in the brain
• Beta Waves: Small fast waves associated with alertness and awakeness
• Alpha Waves: Large, slow waves associated with relaxation and falling asleep
![Page 65: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/65.jpg)
Stages of Sleep
• Stage 1: Small, irregular waves produced in light sleep (people may or may not say they were asleep)– Hypnic Jerk: Reflex muscle twitch
throughout body that may occur in Stage 1
![Page 66: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/66.jpg)
Stage 2
• Deeper sleep; sleep spindles (bursts of distinctive brain-wave activity) appear
![Page 67: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/67.jpg)
Stage 3
• Deeper sleep; Delta waves appear; very large and slow
![Page 68: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/68.jpg)
Stage 4
• Deepest level of normal sleep; almost purely Delta waves
![Page 69: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/69.jpg)

Kinds of Sleep
• Rapid Eye Movements (REM): Associated with dreaming; sleep is very light– Body is very still during REM sleep– Lack of muscle paralysis during REM sleep
is called “REM Behavioral Disorder”• Non-REM (NREM) Sleep: Occurs during
stages 1, 2, 3, and 4; no rapid eye movement occurs– Seems to help us recover from daily
fatigue

Sleep Disturbances
• Insomnia: Difficulty in getting to sleep or staying asleep, or waking early– Sleeping pills exacerbate insomnia; cause
decrease in REM and Stage 4 sleep and may cause dependency
• Drug-Dependency Insomnia: Sleeplessness that follows withdrawal from sleeping pills
![Page 73: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/73.jpg)
Types and Causes of Insomnia
• Temporary Insomnia: Brief period of sleeplessness caused by worry, stress, and excitement.– Avoid fighting it and read a book, for
example, until you’re struggling to stay awake.
• Chronic Insomnia: Exists if sleeping troubles last for more than three weeks.– Adopt regular schedule; go to bed at the
same time each night, for example.

Sleep Disturbances
• Sleepwalking (Somnambulism): Occurs in NREM sleep during Stages 3 and 4
• Sleeptalking: Speaking while asleep; occurs in NREM sleep
![Page 75: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/75.jpg)
Nightmares
• Bad dreams that occur during REM sleep • Imagery Rehearsal: Mentally rehearse the
changed dream before you go to sleep again; may help to eliminate nightmares
![Page 76: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/76.jpg)
Night Terrors
• Total panic and hallucinations may occur– Occurs during Stage 4 sleep– Most common in childhood; may occur in
adults
![Page 77: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/77.jpg)
Sleep Apnea
• Interrupted breathing during sleep; cause of very loud snoring– Hypersomnia: Extreme daytime sleepiness– Apnea can be treated by
• Surgery• Weight loss• Breathing mask
![Page 78: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/78.jpg)
Sudden Infant Death Syndrome
• Also known as SIDS or Crib Death; Sudden, unexplained death of healthy infant (infants should sleep on back or on side to try to prevent)
• SIDS babies have a weak arousal reflex; prevents them from changing positions and resuming breathing after an apnea episode
![Page 79: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/79.jpg)
REM Rebound
• Extra rapid eye movement sleep following REM sleep deprivation
![Page 80: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/80.jpg)
Psychodynamic (Freudian) Theory of Dreaming
• Emphasizes internal conflicts, motives, and unconscious forces
• Wish Fulfillment: Freudian belief that many dreams are expressions of unconscious desires– Much evidence to refute this
• Dream Symbols: Images that have a deeper symbolic meaning
![Page 81: States of Consciousness. What is consciousness? secret-you/ Start at 633 Who passes the mirror self recognition test?](https://reader034.vdocuments.us/reader034/viewer/2022050714/56649ccd5503460f9499885a/html5/thumbnails/81.jpg)
Activation-Synthesis Hypothesis
• Dream content may be affected by motor commands in the brain (that occur during sleep) that are not carried out
