1  Finish consciousness definition  Begin sleep notes  Homework: Continue “Sleep Journal” tonight and reading quiz FRIDAY

2  Awareness of yourself and your environment  Humans experience multiple “states of consciousness”  Sleeping  Waking  Meditating  Hypnosis  Dreaming  Drowsiness  Food or oxygen starvation

3  Another state of consciousness  Allows the body to restore and repair itself  We are far less aware of our selves and surroundings, but we’re still experiencing consciousness!

4  Any biological process that occurs in a 24 hour cycle  Examples: Temperature, Metabolism, Alertness, blood clotting, SLEEP  Teenagers: Most teenagers have a hard time falling asleep before 11:00 pm because of their shifting circadian rhythm cycle

5  If you were to present these findings to the school board, what three quotes or stats would you share?

6  Triggered by body’s production of melatonin, which is the body’s sleep-inducing hormone  Increased production when it’s dark out  Decreased production when it’s light out

7  A single sleep cycle lasts for approximately 90 minutes  Includes five distinct sleep stages

8  Sleep onset: You are AWAKE, yet DROWSY (Alpha Waves)  Have hallucinations or envision things  Myoclonic Jerks (twitches or spasms)  Stage 1: Theta Waves  First five minutes of sleep (very easy to wake)

9  Stage 2 (Still Theta Waves!)  Lasts about 20 minutes (clearly asleep)  Rapid bursts of brain activity (aka sleep spindles)  Half of all sleep takes place here!  Sleep-talking can begin  Stages 3 & 4 (Delta Waves)  30 minutes total  The lower the frequency waves, the deeper the sleep  Getting woken up  Groggy and disoriented

10  REM Cycle  Brain waves resemble Alpha waves  Internally, you are alert (heart rate, eye movement, etc.)  Externally, you are paralyzed  This is when dreaming happens  25% of your sleep  More frequent towards the end of the sleep cycle

11  Insomnia—inability to fall asleep or stay asleep (None)  Sleep apnea—failure to breathe when asleep (All) ( Stop breathing for up to 10 Seconds- hundreds of times a night)  Sleepwalking- Walking/Talking in sleep (No memory) (3,4) Sleepwalking  Night terrors—sudden arousal from sleep and intense fear accompanied by physiological reactions (e.g., rapid heart rate, perspiration). (3,4)  REM sleep disorder—act out your dreams. (REM)  Narcolepsy—overpowering urge to fall asleep (REM) Infographic on sleep! Rusty- The narcoleptic Dog Narcoleptic BritNarcoleptic Girl

12 Fatal Familia Insomnia  Average onset of 50  Takes 7-18 mos. Starts with Insomnia & inability to nap. Gradually lose ability to sleep. Effects: Hallucinations, Panic Attacks Phobias, & eventually severe dementia. *Demonstrates the restorative & reparative function of sleep*

14  An altered state of consciousness (?) in which suggestions can alter perceptions, feelings, thoughts, and behaviors of another person

15  One’s ability to be influenced by the suggestions of a hypnotist.  Varies among people. “You are getting sleepy, very sleepy” “Your eyelids are getting heavy” “Your hands are cemented together, inseparable” “You are swaying back & forth, back & forth”

16  Posthypnotic Amnesia: The forgetting of events that took place while hypnotized.  Age regression: The NON-EXISTENT ability to recall earlier memories (Hypnotist “plants” memories)  Posthypnotic suggestions: Suggestions that are carried out after the client awakens  weight, stress, & headaches  minimal help with addiction  Hypnotic Analgesia: The reduction of the perception of pain that occurs during hypnosis. Hypnotic Analgesia

17  Theories of hypnosis  Notes  Group story  Return Tests  NEW Reading Guide  Homework: AP Practice Exam  FRIDAY

18 Role Theory (Social Influence Theory) State TheoryDissociation Theory (Divided Consciousness Theory) (Ernest Hilgard) It is NOT an altered State of Consciousness! It is a social phenomenon in which people act how they think a hypnotized person should act. Hypnotic Suggestibility differs based on expectations about hypnosis. It is like someone at a party where non-alcoholic beer is being served, but people are told it is alcoholic. They will “act” intoxicated (not by choice), but because they have an EXPECTATION about how intoxicated people act. Hypnosis IS an altered State of Consciousness! Evidenced by changes in perception of pain & dramatic health benefits that can result. AND, sometimes carry out behaviors, even when no one is watching. AND Brain functioning does change while hypnotized. Example: Chandler from “Friends” began acting like a woman even while not sleeping because he listed to a tape that altered his behaviors Our consciousness divides itself One part gives into suggestions, but one part(a Hidden Observer) remains grounded in reality. Hypnotized individuals remain aware of a painful stimulus, they just dissociate (separate) themselves from the actual pain. Example: Someone varies between having a painful broken leg and a moderately uncomfortable leg pain based on one state of consciousness is more dominant

19  Trade hypnosis stories  Dream theories  Drug notes  Homework: Unit Exam THURSDAY  Juniors  GOOD LUCK!

20  With a partner (or on your own), create a short story that describes somebody experiencing hypnosis  Describe the subject’s outward behavior and history, the hypnotist’s actions, what the hypnotist says, etc.  Once you are done, switch stories and explain from each theory’s perspective WHY the person is behaving the way they are

21  One of the most debated and unknown topics within modern psychology  What psychologists think…  We dream to satisfy our own internal desires  To dream to understand and keep memories from the day  We dream to refine our neural pathways  We dream because only certain portions of our brain are active at night  We dream as a means of improving our cognitive development

22  Psychoactive Drugs: Any drug or substance that changes perceptions and moods by influencing neural connectors

23  Type #1: Depressants  Slow down bodily functions and neural behavior  Disrupts one’s memory, self-awareness, control, and motor skills  Examples: Alcohol, tranquilizers, opiates (heroin, morphine)

24  Type #2: Stimulants  Anything that excites neural activity  Very addictive; usually results in a crash (headaches, irritable, depressed, etc.)  Examples: Caffeine, cocaine, meth, Ecstasy

25  Type #3: Hallucinogens (aka Psychedelic)  Distort one’s perceptions of reality by evoking false sensory images  AKA a person sees and experiences things that don’t actually exist  Examples: LSD, Marijuana
