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

6Theories of hypnosis
5
- 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
7Theories of hypnosis
5
- 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.

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

10Dependence Addiction
- Continued use of a psychoactive drug produces
tolerance. With repeated exposure to a drug, the
drugs effect lessens. Thus it takes greater
quantities to get the desired effect.
10
11Misconceptions About Addiction
Addiction is a craving for a chemical substance,
despite its adverse consequences (physical
psychological).
- Addictive drugs quickly corrupt.
- Addiction cannot be overcome voluntarily.
- Addiction is no different than repetitive
pleasure-seeking behaviors.
11
12Psychoactive Drugs
- Psychoactive drugs are divided into three groups.
- Depressants
- Stimulants
- Hallucinogens
12
13Depressants
- Depressants are drugs that reduce neural activity
and slow body functions. They include
- Alcohol
- Barbiturates
- Opiates
13
14Depressants
- Alcohol affects motor skills, judgment, and
memoryand 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
15Depressants
- 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
16Depressants
- Opiates Opium and its derivatives (morphine and
heroin) depress neural activity, temporarily
lessening pain and anxiety. They are highly
addictive. -
- Brain stops releasing endorphines -gt Death by
overdose -

17Stimulants
- 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
18Caffeine Nicotine
- Caffeine and nicotine increase heart and
breathing rates and other autonomic functions to
provide energy.

19Why 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
20Why 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.
22Cocaine
- 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.

23Ecstasy
- 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

24Hallucinogens
- Hallucinogens are psychedelic (mind-manifesting)
drugs that distort perceptions and evoke sensory
images in the absence of sensory input.
Ronald K. Siegel
24
25Hallucinogens
- 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
