1 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Chapter 6: States of Consciousness

2 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 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

3 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Sleep Innate, biological rhythm Microsleep: Brief shift in brain-wave patterns similar to those during sleep

4 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Figure 6.4

5 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 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

6 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

7 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

8 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

9 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

10 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 1

11 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

12 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 2

13 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

14 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 3

15 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stage 4 Sleep Deepest level of normal sleep; almost purely Delta waves

16 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 4

17 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Figure 6.3

18 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

19 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 5

20 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

21 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Stages of Sleep, Part 6

22 Psychology: A Modular Approach to Mind and Behavior, Tenth Edition, Dennis Coon Chapter 6 Figure 6.8

23 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

24 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 youre struggling to stay awake

25 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

26 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

27 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

28 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

29 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

40 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 shows 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

41 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
