1 AP Psych Class Announcements: Next Psych Club meeting: Monday 11/19 Topic: Lauren Deveanu 2006 Bayside Grad Lauren is finishing her Psychology degree. She works with women who are incarcerated or have legal issues with the criminal justice system. Come hear her about her work encouraging them in recovery and prevent relapses. Aim: to compare the three main drug categories and their effects. Do NOW: 1.quiz 108-25 2.What did you learn from the addiction simulation? 3.Read “Effects of Long Term Cannabis Use” HW : Study notes for test Answer practice questions

2 States of Consciousness

3 Sleep Sleep is a state of consciousness. We are less aware of our surroundings. Circadian Rhythm

4 Our biological clock Body temp rises in the am and falls in pm The hypothalamus sends a signal to the pineal gland to increase melatonin when it gets dark Jet lag- changes in time/light mess with our circadian rhythm

5 Sleep Cycles Use an EEG machine to measure stages of sleep.

6 Sleep Onset (hypnagogic stage) When you are the onset of sleep you experience alpha waves. Produces mild hallucinations, like a feeling of falling. Lose awareness of time

7 Stage 1 Kind of awake and kind of asleep. Only lasts a few minutes, and you usually only experience it once a night.

8 Stage 2 Brain waves get progressively slower. Begin to show sleep spindles…short bursts of rapid brain waves.

9 Stages 3 and 4 Slow wave sleep. You produce Delta waves. If awoken you will be very groggy. Vital for restoring body’s growth hormones and good overall health. From stage 4, your brain begins to speed up and you go to stage 3, then 2….then ……

10 What can happen during Stage 4?? Sleep walking, talking Night terrors (common among children b/t ages of 3-12) Why? Your body is NOT paralyzed during this stage

11 Stages of Sleep

12 REM Sleep Rapid Eye Movement Often called paradoxical sleep. Brain is very active with alpha waves. Dreams usually occur in REM. Body is essentially paralyzed.

13 So….. Amount of REM increases as night goes on Amount of NREM decreases REM sleep = alpha waves (Alpha/active) Stage 4 sleep = delta waves (Delta/deep) http://www.youtube.com/watch?v=- ihJnOTGj8A&feature=relatedhttp://www.yout ube.com/watch?v=pihygVBjAYU&feature=relat ed http://www.youtube.com/watch?v=- ihJnOTGj8A&feature=relatedhttp://www.yout ube.com/watch?v=pihygVBjAYU&feature=relat ed

14 REM Rebound If you fail to get your REM the night before, the brain will attempt to double up on the time spent in REM the next night

15 True or False???? 1.When sleeping, the brain blocks out all outside stimuli. 2.PET scans reveal that the parietal and frontal lobes are active during REM sleep. 3.Some people never dream. 4.As we age, we switch from becoming “night owls” to a “morning” person. 5. Infants spend about 16 hours in REM.

16 Sleep Disorders

17 Insomnia Persistent problems falling asleep Effects 10% of the population

18 Narcolepsy Suffer from sleeplessness and may fall asleep at unpredictable or inappropriate times. Directly into REM sleep Less than.001 % of population. Click above to see Skeeter the narcoleptic dog. http://www.youtube.co m/watch?v=X0h2nleWT wI http://www.youtube.co m/watch?v=X0h2nleWT wI

19 Sleep Apnea A person stops breathing during their sleep. Wake up momentarily, gasps for air, then falls back asleep. Very common, especially in heavy males. Marked by loud snoring http://www.youtube.co m/watch?v=Wm-TZ- dO_rQ http://www.youtube.co m/watch?v=Wm-TZ- dO_rQ

20 Night Terrors Wake up with rapid heart beat, panicked and have no idea why. Not a nightmare. Most common in children (boys) between ages 2-8.

21 Somnambulism Sleep Walking Most often occurs during the first few hours of sleeping and in stage 4 (deep sleep). If you have had night terrors, you are more likely to sleep walk when older.

22 Why do we need sleep? 1. It protects us (ancestors didn’t walk around much in the dark) 2. helps restore cells, tissues etc.

23 Effects of Sleep Deprivation Difficulty concentrating Decreased productivity, more errors Increased irritability, moodiness http://www.youtube.com/watch?v=zIV1f6aJH cM&feature=related http://www.youtube.com/watch?v=zIV1f6aJH cM&feature=related

24 Why Do We Dream? A few theories:

25 1. Freud’s Theory of Dreams Freud felt that dreams are a roadway into our unconscious. He thought they were a safe way to discharge unacceptable urges, feeling

26 Freud’s theory about dreams He analyzed dreams into two parts: 1. Manifest Content (the dream’s storyline) 2. Latent Content (the dream’s underlying meaning)

27 Ex of Freud’s analysis: Manifest Content: “I was a child again and was playing in the front yard. All of a sudden a big storm developed. I ran into the house for cover and next thing I know, a tree from the yard blows down and falls on the house.”

28 Freud ex. Con’t: Latent Content The dream reveals a trauma that occurred in childhood, probably molestation. The storm represents something that took away your childhood (the storm forced you to stop playing). The house represents your female reproductive organs which were hurt by male genitalia, the tree.

29 2. Activation-Synthesis Theory Our Cerebral Cortex is trying to interpret random electrical activity we have while sleeping. That is why dreams sometimes make no sense. Biological Theory.

30 3. Information-Processing Theory We are merely processing the events of the day. Dreams are a way to deal with the stresses of everyday life. We tend to dream more when we are more stressed.

31 Hypnosis

32 Videos http://www.youtube.com/watch?v=KTml6AY- 1RQ&feature=related http://www.youtube.com/watch?v=KTml6AY- 1RQ&feature=related http://www.youtube.com/watch?v=h4aB6vvV liE&feature=related http://www.youtube.com/watch?v=h4aB6vvV liE&feature=related

33 Hypnosis Is it an altered state of consciousness? What is: Posthypnotic suggestion Posthypnotic amnesia

34 Hypnosis: Myth or Truth? Place a M if the statement is a myth Place a T if the statement is true

35 Which of the following is backed by research evidence? Under hypnosis: 1 your memory is more accurate. 2. you can “age regress” with remarkable accuracy 3. can get people to tell the truth 4. get people to feel less pain 5. get people to do unlawful things 6. can demonstrate superhuman strength

36 Who makes for a good subject to hypnotize? 10-15% Very difficult to hypnotize 70-80% Can experience some suggestions 10-15% Can experience all or most suggestions, even difficult ones *easiest are most imaginative and fantasy prone

37 Hypnotic Theories: 1. Social Influence 2. Divided Consciousness Theory

38 Social Influence Theory Think hypnosis is NOT an altered state of consciousness. Believe it is a social phenomenon where people want to believe and are trying to please the hypnotist. Works better on people with richer fantasy lives.

39 Divided Consciousness Theory They believe that hypnosis IS an altered state of consciousness. They argue: Subjects will carry out suggestion even when no one is watching!!!!

40 How does the Divided Consciousness theory explain hypnosis? They believe that consciousness is truly divided under hypnosis Co Conscious mind Under hypnosis

41 Dissociation Demonstrated by researcher, Ernest Hilgard. We voluntarily divide our consciousness up like when we doodle in class or get lost in a good book. Ice Water Experiment. We have a “hidden observer”, a level of us that is always aware.

42 Highway hypnosis Getting “lost” in a good book or movie and not hear someone calling your name Your eyes scan to read, but your mind does not actually read Examples of dissociation

43 Drugs

44 Drugs are either…. Agonists Antagonists Reuptake inhibitors If a drug is used often, a tolerance is created for the drug. Thus you need more of the drug to feel the same effect. If you stop using a drug you can develop withdrawal symptoms.

45 Stimulants Speed up body processes. More powerful ones (like cocaine) give people feelings of invincibility.

46 Depressants Slows down body processes. Alcohol Barbiturates and tranquilizers

47 Hallucinogens Psychedelics Causes changes in perceptions of reality LSD, peyote, psilocybin mushrooms and marijuana. Reverse tolerance or synergistic effect

48 Opiates Has depressive and hallucinogenic qualities. Agonist for endorphins. Derived from poppy plant. Morphine, heroin, methadone and codeine. All these drugs cross the placental barrier….teratogens.
