Individual Warm-up Match the Perspective with the Key Idea • • • • • • • • • feelings and desires are most important. Psychodynamic • it's about survival and Behavioral adaptation. Cognitive • thinking in groups. Humanistic Biomedical • measurable behavior is most Evolutionary important. Socio-cultural • thinking and intelligence are Social Cognitive most important. • unconscious is most important • brain and nerves, medication. • it's all about society. Hypnotic Ability and Susceptibility • An induced state of awareness, characterized by heightened suggestibility, deep relaxation, and highly focused attention. 1. Openness to suggestion is key. 2. 20% of people are highly hypnotizable; 10% difficult/impossible 3. Correlates to rich fantasy life, imagination, ability to focus attention and ignore distraction 4. Expectancy plays a role C. Hypnotic Ability and Susceptibility Inaccurate memories are common can sometimes boost recall False recollections can occur Memories are often constructed Normal rules of memory formation, storage, and retrieval apply H. Uses of Hypnosis 1. control undesired symptoms and behaviors 2. Used for pain control 3. treatment of headaches, asthma, warts, stress-related skin disorders, self-control problems such as smoking, weight control, and nail biting Check Your Understanding • Hypnotic suggestibility refers to one's: • a.) ability to be hypnotized. • b.) intelligence. • c.) ability to be misled while under hypnosis. • d.) All of the above. • Who tends to have a high degree of hypnotic suggestibility? • a.) people with vivid imaginations • b.) people who easily daydream • c.) about 20% of the population • d.) all of the above Common Hypnosis Techniques • Age Regression – go back to a certain age and describing it when under hypnosis. – Research shows the speech patterns are still adult. • Post-hypnotic suggestion – a command to carryout after the hypnosis is over. – Ex. Quit smoking • Posthypnotic Amnesia – Hypnotist directs you not to remember something experienced while under hypnosis. Check Your Understanding • Posthypnotic Amnesia • Age Regression • Posthypnotic Suggestion • “After we are finished, you won’t remember this.” • “Let’s go back to when you were 10 years old.” • When you feel the nausea, it’ll be warmth instead.” Theories About Hypnosis • Dissociation Theory – – – – Under hypnosis, our consciousness is divided. One part of the mind is open to hypnotic suggestion. The other part still retains an awareness of reality. Hand in freezing water • Subject said she felt nothing • Subject still raised finger to indicate pain. – “Hidden Observer” – one part of the mind is aware of the pain, but the other part felt nothing. • State Theory – Hypnosis is an altered state of consciousness where the subject is unaware of his environment, and so agrees with what a hypnotist suggests. • Role Theory – People under hypnosis are playing a role. – They get so committed to their role that they do whatever the hypnotist suggests. Check Your Understanding • Dissociation Theory • State Theory • Role Theory • Hypnosis as an altered state of consciousness • Hypnosis as divided consciousness • Hypnosis as conforming to expectations Why should meditation promote feelings of well-being and relaxation? • Researchers have reported that the physiological effects of meditation are related to lowered activity of the sympathetic nervous system, the branch of the autonomic nervous system that functions as the arousal center during emergency or stressful situations. • The most common bodily change reported is hypometabolism, which is characterized by decreases in the body's metabolic rate as reflected by lowered oxygen consumption, in heart and respiration rates, and in carbon dioxide production. Psychoactive Drugs • Just how large a problem is substance abuse in the U.S.? Consider the following statistics. In 2002: – An estimated 54 million Americans reported binge drinking at least once in the past month, and nearly 16 million reported drinking heavily nearly every day. – An estimated 19.5 million Americans reported being current illicit drug users. Marijuana was the most commonly used illicit drug, followed by nonprescription use of prescription medication. – An estimated 2 million persons were current cocaine users, and 567,000 of these used crack. About 1.2 million persons reported using hallucinogens, including 676,000 who used Ecstasy. There were an estimated 166,000 heroin users. • (From information gathered by the Substance Abuse and Mental Health Services Administration.) • Though many substance abusers may say they want to stop, the effects of psychoactive substances such as alcohol and illicit drugs can be very powerful. In this lesson, you'll learn about different classes of drugs and how they influence the body. You'll also learn about factors such as tolerance and phenomena such as withdrawal that can make it difficult to stop using these substances. Drugs and Altered Consciousness • by altering the interaction between neurotransmitters and receptors – Agonists bind to the receptors and mimic effects of normal neurotransmitters • Change the level of neurotransmitters in the brain. – Antagonists bind to the receptors and prevent (slow down) the normal neurotransmitters from binding • Change the level of neurotransmitters in the brain. Physical Dependence or Addiction • • This is a physiological state in which drug use is necessary to prevent a withdrawal symptom Withdrawal is painful and long – that is why there is such a high rate of relapse for drug users. • Tolerance – This is a condition in which increasingly large drug doses are necessary to achieve the same effect • Psychological Dependence – This is a condition in which the person continues drug use despite adverse effects, needs the drug for a sense of well being, and is preoccupied with obtaining the drug if it is no longer available • Learned Expectations Contribute to the Effects of Many Drugs – The power of suggestion and experience Categories of drugs • Depressants – Slow down your Central Nervous System by inhibiting GABA – Slow down your reaction time and interfere with judgment. – Alcohol, barbiturates, and tranquilizers (valium) • Stimulants – arouse the Sympathetic NS by increasing norepinephrine – Make an individual feel more confident or energetic. Sense of euphoria. – Nicotine, caffeine, amphetamines, cocaine • Opiates – Powerful pain killers – – – – Most addictive Work by mimicking endorphins in the brain. Euphoria or loss of pain. Heroin, morphine, and codeine • Psychedelics (or hallucinogenics) – Loss of reality, serotonin agonist • Know psychological v. physical dependence Check your Understanding • Which of the following is not an example of a depressant? • A. Alcohol • B. Barbiturates • C.Tranquilizers • D. Cocaine • Drugs that speed up your nervous system and can cause heart failure are called: • A. Stimulants • B. Depressants • C. Opiates • D. Hallucinogens Hallucinogens • Psychedelic drugs that change your perception of reality. – Some (LSD) are produced in a lab – Others (peyote, mushrooms, marijuana) are natural substances. – Traces of these drugs stay in the body for weeks after they are taken – Reverses tolerance – because traces stay in your blood – you need less to get the same effect. Amphetamines and Methamphetamines • • • Potent stimulants that are highly addictive and produce feelings of exhilaration and power are amphetamines (A stimulant to the central nervous system that increases energy and decreases appetite; used to treat narcolepsy and some forms of depression.) sometimes referred to as "speed" or "uppers". They're also associated with violent behavior, which can arise from the feelings of invulnerability the drug produces and from the depression that occurs when the drug wears off. Commercially produced amphetamines include Benzedrine and Dexedrine. • There are synthetic and extremely addictive amphetamines called methamphetamines: – A highly psychologically addictive, illicit, synthetic stimulant drug which induces feelings of euphoria. In pure form, it is a colorless crystalline solid, sold on the streets as glass, ice, or crystal. As less pure form, it's sold as crystalline powder referred to as crank or speed, or in rock formation as tweak, dope, or raw. • sometimes referred to as "crank" or "ice"). They are often produced illegally in a dangerous process involving highly toxic chemicals. • Dopamine plays an important role in the regulation of pleasure. Dopamine is manufactured is in the nerve cells within the ventral tegmental area. It's released in the nucleus accumbens and the frontal cortex. Barbiturates • Barbiturates are powerful depressants that are classified as sedatives or hypnotics. • These highly addictive drugs are legal when prescribed by physicians, but can be very dangerous when abused or mixed with other drugs. • Types of barbiturates include amobarbital and phenobarbital. Ecstasy or MDMA • MDMA has both stimulant (amphetamine-like) and hallucinogenic (LSD-like) properties. It also produces spasms in the jaw muscles and a sense of "oneness" with others. • Though the drug isn't addictive, it is neurotoxic, and in high enough doses it destroys serotonincontaining neurons in the brain. It also elevates body temperature, which can cause damage to muscles, the heart and blood vessels, and kidneys. Check Your Understanding • Amphetamines • Barbiturates • MDMA • Produces spasms in the jaw muscles • Sometimes referred to as “crank” or “ice” • Nervous system depressants • Powerful depressants • Destroys serotonin-containing neurons in the brain. • Types include Benzadrine and Dexadrin • Has both stimulate & hallucinogenic properties. • Associated with violent behavior • Types include amobarbital, and phenobarbital Physical and Psychological Addiction • The Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IV) makes a distinction between substance abuse and substance dependence. The concepts of tolerance and withdrawal are crucial to making these distinctions. • Tolerance is defined as the need for larger amounts of the substance to achieve the desired effect. For example, if you previously needed a cup of coffee to get going in the morning, but now you need two or three, then you have become more tolerant to the effects of caffeine. • Withdrawal refers to the physical (and sometimes psychological) effects experienced after discontinuing a drug after a period of use. Many substances have characteristic withdrawal symptoms, and some of them can be quite dangerous. Withdrawal from severe alcohol abuse, for example, can involve fever, agitation, nausea, vomiting, delirium, seizures, and even death. For this reason, experts strongly recommend that, in cases of severe substance abuse, detoxification take place under medical supervision. • Withdrawal symptoms can be psychological as well as physical, and psychological withdrawal symptoms are no less difficult to handle. Many substances aren't necessarily physically addictive, but they exert a powerful psychological hold on the user, making withdrawal a very uncomfortable experience.
