Some Early Definitions
• Consciousness: All the sensations, perceptions, memories, and feelings you are aware of in any instant– Waking Consciousness: Normal, clear,
organized, alertness
• Altered State of Consciousness (ASC): Changes that occur in quality and pattern of mental activity
![Page 3: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/3.jpg)

Sleep
• Innate, biological rhythm
• Microsleep: Brief shift in brain-wave patterns similar to those during sleep
![Page 4: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/4.jpg)

Sleep Problems
• Sleep Deprivation: Sleep loss; being deprived of needed amounts of sleep
• Sleep-Deprivation Psychosis: Confusion, disorientation, delusions, and hallucinations that occur because of sleep loss
• Sleep Patterns: Daily rhythms of sleep and waking
![Page 6: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/6.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Rhythms
• Circadian Rhythms: Bodily changes that occur every 24 hours
• Biological Rhythm: Any repeating cycle of biological activity
![Page 7: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/7.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Jet Lag
• Disturbed body rhythms caused by rapid travel east or west
• Major time shifts (5 hours or more) can cause very slow adaptation
• Direction of travel affects adaptation, and thus, severity of jet lag– MUCH easier to go from east to west, than
west to east
• Preadaptation: Gradual matching of sleep-waking cycles to a new time schedule
![Page 8: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/8.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Measuring Sleep Changes
• Electroencephalograph (EEG): Brain-wave machine; amplifies and records electrical activity in the brain
• Beta Waves: Small fast waves associated with being alert and awake
• Alpha Waves: Large, slow brainwaves associated with relaxation and falling asleep
![Page 9: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/9.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Stage 1 Sleep
• Small, irregular waves produced in light sleep (people may or may not say they were asleep)– Hypnic Jerk: Reflex muscle contraction
![Page 10: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/10.jpg)

Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Stage 2 Sleep
• Deeper sleep; sleep spindles (bursts of distinctive brain-wave activity) appear
![Page 12: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/12.jpg)

Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Stage 3 Sleep
• Deeper sleep; Delta waves appear; very large and slow
![Page 14: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/14.jpg)

Stage 4 Sleep
• Deepest level of normal sleep; almost purely Delta waves
![Page 16: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/16.jpg)

Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Two Basic 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
![Page 19: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/19.jpg)

Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
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– EEG patterns return to Stage 1
![Page 21: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/21.jpg)

Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Some Sleep Disturbances
• Insomnia: Difficulty in getting to sleep or staying asleep– 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 24: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/24.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
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
![Page 25: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/25.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Some More Sleep Concerns
• 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
• Tryptophan: Amino acid (chemical) that produces sleep
![Page 26: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/26.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Sleep Disturbances
• Sleepwalking (Somnambulism): Occurs in NREM sleep during Stages 3 and 4
• Sleeptalking: Speaking while asleep; occurs in NREM sleep
![Page 27: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/27.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Some Other Sleep Disturbances
• Nightmares: Bad dreams that occur during REM sleep – May occur once or twice a month; brief and
easily remembered– Imagery Rehearsal: Mentally rehearse the
changed dream before you go to sleep again; may help to eliminate nightmares
![Page 28: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/28.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Night Terrors
• Night Terrors: Total panic and often hallucinations of frightening dream images may occur– Occurs during Stage 4 sleep– Most common in childhood; may occur in
adults– Not remembered
![Page 29: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/29.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Physiological Sleep Problems
• Sleep Apnea: Repeated interrupted breathing during sleep; cause of very loud snoring– Hypersomnia: Extreme daytime sleepiness– Apnea can be treated by
• Surgery
• Weight loss
• Breathing mask
![Page 30: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/30.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Sudden Infant Death Syndrome (SIDS)
• Sudden, unexplained death of an apparently healthy infant (infants should sleep on back or on side to try to prevent)
• Also known as Crib Death
![Page 31: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/31.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Dreams
• Psychodynamic (Freudian) Theory: 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 32: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/32.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Activation-Synthesis Hypothesis
• Dream content may be affected by motor commands in the brain during sleep that are not carried out
![Page 33: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/33.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Hypnosis
• Altered state of consciousness characterized by intensely 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
![Page 34: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/34.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
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 35: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/35.jpg)

Hypnosis Can
• Help people relax
• Reduce pain
• Get people to make better progress in therapy
![Page 37: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/37.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Hypnosis Cannot
• Produce acts of superhuman strength
• Produce age regression
• Force you to do things against your will
![Page 38: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/38.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Stage Hypnosis
• Simulation of hypnotic effects, done to entertain
![Page 39: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/39.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Tricks of the Hypnosis 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 removed
• 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 40: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/40.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
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 hypnotist only needs to direct them
• Stage Hypnotists Use Tricks: Stage hypnosis is 50% deception and 50% taking advantage of the situation
• Conclusion: Stage hypnotists entertain; they rarely hypnotize
![Page 41: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/41.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
Meditation
• Mental exercise designed to focus attention and interrupt flow of thoughts, worries, and analyses
• Concentrative Meditation: Attention is paid to a single focal point (i.e., object, thought, etc.)– Produces relaxation response and thus
works to reduce stress
• Receptive Meditation: Based on widening attention span to become aware of everything experienced at a given moment
![Page 42: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/42.jpg)
Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6
More on Meditation
• Mantra: Word(s) or sound(s) repeated silently during concentrative meditation
• Relaxation Response: Occurs at time of relaxation; innate physiological pattern that opposes body’s fight or flight responses
![Page 43: Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness.](https://reader036.fdocuments.us/reader036/viewer/2022081518/5516396d550346b2068b5014/html5/thumbnails/43.jpg)

Stimulants
• Amphetamine: Synthetic stimulants that excite 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
