  1. States ofConsciousnessChapter 6 1

  2. Hypnosis A social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur. http://iddiokrysto.blog.excite.it Hypnos: Greek god of sleep 2

  3. Facts and Falsehood Those who practice hypnosis agree that its power resides in the subject’s openness to suggestion. Yes, to some extent. Can anyone experience hypnosis? No. Can hypnosis enhance recall of forgotten events? 3

  4. Facts and Falsehood No. Can hypnosis force people to act against their will? Yes. Self-suggestion can heal too. Can hypnosis be therapeutic? Yes. Lamaze can do that too. Can hypnosis alleviate pain? 4

  5. Explaining the Hypnotized State Social Influence Theory: Hypnotic subjects may simply be imaginative actors playing a social role. Divided ConsciousnessTheory: Hypnosis is a special state of dissociated (divided) consciousness (Hilgard, 1986, 1992).

  6. 5 Theories of hypnosis Social Influence Theories Effects of hypnosis result from interaction between social influence of the hypnotist and the beliefs and expectations of the subject. Can explain “alien abduction” and “past-life regression”

  7. 5 Theories of hypnosis Dissociation theories • Hypnosis is a split in consciousness in which one part of the mind operates independently of consciousness • During hypnosis, dissociation occurs between an executive control system (probably in the frontal lobes) and other systems of thinking and acting.

  8. Both Theories Mimi Forsyth 8

  9. Drugs and Consciousness Psychoactive Drug: A chemical substance that alters perceptions and mood (affects consciousness). 9

  10. Dependence & Addiction Continued use of a psychoactive drug produces tolerance. With repeated exposure to a drug, the drug’s effect lessens. Thus it takes greater quantities to get the desired effect. 10

  11. Misconceptions About Addiction Addictive drugs quickly corrupt. Addiction cannot be overcome voluntarily. Addiction is no different than repetitive pleasure-seeking behaviors. Addiction is a craving for a chemical substance, despite its adverse consequences (physical & psychological). 11

  12. Psychoactive Drugs Psychoactive drugs are divided into three groups. • Depressants • Stimulants • Hallucinogens 12

  13. Depressants Depressantsaredrugs that reduce neural activity and slow body functions. They include: • Alcohol • Barbiturates • Opiates 13

  14. Depressants Alcoholaffects motor skills, judgment, and memory…and increases aggressiveness while reducing self awareness. • It slows down the sympathetic nervous system • Suppresses the frontal lobe activity • In large amount, stops breathing and heartbeat 14

  15. Depressants 2. Barbiturates:Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment. Nembutal, Seconal, and Amytal are some examples. 15

  16. Depressants Opiates:Opium and its derivatives (morphine and heroin) depress neural activity, temporarily lessening pain and anxiety. They are highly addictive. Brain stops releasing endorphines -> Death by overdose http://opioids.com/timeline 16

  17. Stimulants Stimulants are drugs that excite neural activity and speed up body functions. They stimulate autonomic functions, and neurotransmitters. • Caffeine • Nicotine • Cocaine • Ecstasy • Amphetamines • Methamphetamines 17

  18. Caffeine & Nicotine Caffeine and nicotine increase heart and breathing rates and other autonomic functions to provide energy. http://office.microsoft.com/clipart http://www.tech-res-intl.com 18

  19. Why Do People Smoke? People smoke because it is socially rewarding. Smoking is also a result of genetic factors. Russel Einhorn/ The Gamma Liason Network 19

  20. Why Do People Smoke? Nicotine takes away unpleasant cravings (negative reinforcement) by triggering epinephrine, norepinephrine, dopamine, and endorphins. Nicotine itself is rewarding (positive reinforcement). 20

  21. Nicotine kills nearly 5 million of 1.3 billion smokers, worldwide • Smoking delivers its hit of nicotine within 7 seconds.

  22. Cocaine Cocaine induces immediate euphoria followed by a crash. Crack, a form of cocaine, can be smoked. Other forms of cocaine can be sniffed or injected. http://www.ohsinc.com 22

  23. Ecstasy Ecstasy or Methylenedioxymethamphetamine (MDMA) is a stimulant and mild hallucinogen. It produces a euphoric high and can damage serotonin-producing neurons, which results in a permanent deflation of mood and impairment of memory. It interferes with circadian rhythms It has dehydrating effect Greg Smith/ AP Photos 23

  24. Hallucinogens Hallucinogensare psychedelic (mind-manifesting) drugs that distort perceptions and evoke sensory images in the absence of sensory input. Ronald K. Siegel 24

  25. Hallucinogens • LSD:(lysergic acid diethylamide) powerful hallucinogenic drug that is also known as acid. • It creates perceptual hallucinations 25 Hemp Plant

  26. THC (delta-9-tetrahydrocannabinol):is the major active ingredient in marijuana (hemp plant) that triggers a variety of effects, including mild hallucinations. • Impair motor coordination and perceptual tasks and decreases reaction time • Research shows there is a possibility that our brain produces THC like molecule that reduces pain

  27. Drugs Summary 27

  28. Influences on Drug Use The graph below shows the percentage of US high- school seniors reporting their use of alcohol, marijuana, and cocaine from the 70s to the late 90s. 28

  29. Influences on Drug Use The use of drugs is based on biological, psychological, and social-cultural influences. 29

  30. Marijuana Use The use of marijuana in teenagers is directly related to the “perceived risk” involved with the drug. 30

  31. Influence for Drug Prevention and Treatment • Education about the long-term costs • Efforts to boost people’s self-esteem and purpose • Attempts to modify peer associations and teaching refusal skills 31
