Transcript Chapter Three Part Two - K-Dub

General
Psychology
Scripture
• Matthew 5:8
Blessed are the pure in heart, for they will see God.
The pure in heart - They who love God with all their
hearts. They shall see God - In all things here;
hereafter in glory. Who seek not only to have the
external actions correct, but who desire to be holy
in heart, and who are so. Man looks on the
outward appearance, but God looks on the heart.
Another Possible State of Consciousness:
HYPNOSIS
Text definition: Hypnosis is a social
interaction in which one person (the
hypnotist) suggests to another (the
subject) that certain perceptions,
feelings, thoughts, or behaviors will
spontaneously occur.
Alternate definition: Hypnosis is
a cooperative social action in
which one person is in a state of
being likely to respond to
suggestions from another person.
 This state has been called
heightened suggestibility as
well as a trance.
 Controversy: does this social
interaction really require an
altered state of consciousness?
“Your arm
may soon
feel so
light that it
rises…”
Types of Hypnotic Suggestions
The subject
may be led into
changes in:
perceptions
(“The headache is fading away.”)
behavior
(“Your arm might rise by itself.”)
emotions
(“You are feeling more relaxed and confident.”)
attitudes
(“I get nutrition from food, and get comfort from
memory friends.”)
(“You got lost in a mall as a child.”)
Induction Into Hypnosis
Hypnotic induction, the
inducing of a hypnotic state,
is the process by which a
hypnotist leads someone
into the state of heightened
suggestibility.

necessary.
• They are able to focus and to
lose themselves in fantasy.
• The hypnotic induction
method may happen to work
just right.
Theories Explaining Hypnosis
Divided Consciousness Theory
Hypnosis is a special state of
dissociated (divided)
consciousness of our dual-track
mind.
Social Influence Theory
Hypnotic subjects may simply
be imaginative people who go
along with the “subject” role
they have agreed to play.
Benefits of
Hypnosis for
Some People:
 blocking awareness
of pain, even enough
for surgery without
anesthesia
 reducing obesity,
anxiety, and
hypertension
 improving
concentration and
performance
What Hypnosis
Cannot Do:
 work when people
refuse to
cooperate
 bestow
‘superhuman’
abilities or
strength
 accurately boost
recall of forgotten
events (it is more
likely to implant
false recall)
Altering Consciousness
Drugs
Psychoactive drugs are
chemicals introduced
into the body which alter
perceptions, mood, and
other elements of
conscious experience.
Dependence/Addiction
 Many psychoactive
drugs can be harmful
to the body.
 Psychoactive drugs
are particularly
dangerous when a
person develops an
addiction or becomes
dependent on the
substance.
 Factors related to
addiction:
 tolerance
 withdrawal
 impact on daily life
of substance use
 physical and
psychological
dependence
Tolerance
Tolerance of a
drug refers to
the diminished
psychoactive
effects after
repeated use.
Tolerance feeds
addiction
because users
take increasing
amounts of a
drug to get the
desired effect.
Withdrawal
 After the benefits of a
substance wear off,
especially after tolerance
has developed, drug
users may experience
withdrawal (painful
symptoms of the body
readjusting to the
absence of the drug).
 Withdrawal worsens
addiction because users
want to resume taking
the drug to end
withdrawal symptoms.
Dependence
In physical
dependence,
the body has been
altered in ways
that create
cravings for the
drug (e.g. to end
withdrawal
symptoms).
In psychological
dependence,
a person’s
resources for coping
with daily life wither
as a drug becomes
“needed” to relax,
socialize, or sleep.
Dependence
on a substance (or activity?)
 Tolerance: the need to use more to receive the
desired effect
 Withdrawal: the distress experienced when the
“high” subsides
 Using more than intended
 Persistent, failed attempts to regulate use
 Much time spent preoccupied with the
substance, obtaining it, and recovering
 Important activities reduced because of use
 Continued use despite aversive consequences
Depressants
Examples:
 alcohol
 barbiturates
 opiates
Depressants are chemicals
that reduce neural activity
and other body functions.
Effects of Alcohol Use
Impact on functioning
 Slow neural processing,
reduced sympathetic
nervous system activity, and
slower thought and physical
reaction
 Reduced memory
formation caused by
disrupted REM sleep and
reduced synapse formation
 Impaired self-control,
impaired judgment, selfmonitoring, and inhibition;
increased accidents and
aggression
Chronic Use:
Brain damage
Barbiturates
Barbiturates are
tranquilizers--drugs that
depress central nervous
system activity.
 Examples: Nembutal,
Seconal, Amytal
 Effects: reducing
anxiety and inducing
sleep
 Problems: reducing
memory, judgment,
and concentration; can
lead to death if
combined with alcohol
Opiates:
Highly Addictive Depressants
 Opiates depress
nervous system
activity; this
reduces anxiety,
and especially
reduces pain.
 High doses of
opiates produce
euphoria.
 Opiates work at
receptor sites for
the body’s natural
pain reducers
(endorphins).
Opiates are
chemicals such
as morphine
and heroin that
are made from
the opium
poppy.
Stimulants
Stimulants are drugs which
intensify neural activity
and bodily functions.
Some physical effects of stimulants:
dilated pupils, increased breathing and
heart rate, increased blood sugar,
decreased appetite
Examples of stimulants:
 Caffeine
 Nicotine
 Amphetamines,
Methamphetamine
 Cocaine
 Ecstasy
Caffeine
 adds energy
 disrupts sleep for 3-4
hours
 can lead to withdrawal
symptoms if used daily:
 headaches
 irritability
 fatigue
 difficulty
concentrating
 depression
Nicotine
The main
effect of
nicotine use
is
ADDICTION.
Why do people smoke?
 Starting to smoke: invited
by peers, influenced by
culture and media
 Continuing: positively
reinforced by physically
stimulating effects
 Not stopping: after regular
use, smokers have difficulty
stopping because of
withdrawal symptoms such
as insomnia, anxiety,
distractibility, and irritability
Cocaine
 Cocaine blocks reuptake (and thus increases
levels at the synapse of:
 dopamine (feels rewarding).
 serotonin (lifts mood).
 norepinephrine (provides energy).
 Effect on consciousness: Euphoria!!! At
least for 45 minutes…
What happens
next?
 Euphoria crashes
into a state
worse than
before taking the
drug, with
agitation,
depression, and
pain.
 Users develop
tolerance; over
time, withdrawal
symptoms of
cocaine use get
worse, and users
take more just to
feel normal.
 Cycles of
overdose and
withdrawal can
sometimes bring
convulsions,
violence, heart
attack, and
death.
Methamphetamine
 Methamphetamine triggers the sustained release of
dopamine, sometimes leading to eight hours of euphoria and
energy.
 What happens next: irritability, insomnia, seizures,
hypertension, violence, depression
 “Meth” addiction can become all-consuming.
From 1998 to 2002: Extreme Makeover, Meth Edition
Ecstasy/MDMA
(MethyleneDioxyMethAmphetamine)
 Ecstasy is a synthetic stimulant that
increases dopamine and greatly
increases serotonin.
 Effects on consciousness: euphoria,
CNS stimulation, hallucinations, and
artificial feeling of social connectedness
and intimacy
What Happens Next?
 In the short run, regretted behavior, dehydration, overheating, and
high blood pressure.
 Make it past that, and you might have:
 damaged serotonin-producing neurons, causing permanently
depressed mood
 disrupted sleep and circadian rhythm
 impaired memory and slowed thinking
 suppressed immune system
Hallucinogens
LSD (lysergic acid diethylamide)
 LSD and similar drugs interfere with
serotonin transmission.
 This causes hallucinations--images
and other “sensations” that didn’t
come in through the senses.
Marijuana/THC (delta-9TetraHydroCannabinol)
 Marijuana binds with brain
cannabinoid receptors.
 Effect on consciousness:
 amplifies sensations
 disinhibits impulses
 euphoric mood
 lack of ability to sense satiety
Marijuana/THC:
What Happens Next?
 Impaired motor
coordination,
perceptual ability, and
reaction time
 THC accumulates in the
body, increasing the
effects of next use
 Over time, the brain
shrinks in areas
processing memory and
emotion
 Smoke inhalation
damage
Summary: Desired Effects of Drugs
Summary: Aversive Effects of Drugs
Prevalence of Drug Use in the
United States
Nicotine Use as of 2011:
26 percent of high school
dropouts smoke; 6 percent
of people with graduate
degrees smoke
What influences can lead to drug use?
What can turn drug use into
dependence?
 Biological factors: dependence in
relatives, thrill-seeking in childhood,
genes related to alcohol sensitivity and
dependence, and easily disrupted
dopamine reward system
 Psychological factors: seeking
gratification, depression, problems
forming identity, problems assessing risks
and costs
 Social influences: media glorification,
observing peers
Influence for Drug Prevention and
Treatment
1. Education about the long-term costs
2. Efforts to boost people’s self-esteem
and purpose
3. Attempts to modify peer
associations and teaching refusal
skills
