STATES OF
CONSCIOUSNESS
LEVELS OF CONSCIOUSNESS
We know that various
levels exists beyond
the conscious level.
LEVELS OF CONSCIOUSNESS
• Conscious Level
• Nonconscious Level
• Preconscious Level
• Subconscious Level/
Unconscious Level
LEVELS OF CONSCIOUSNESS
EXPLAINED
• Conscious- the things
that you are currently
thinking, feeling and
experiencing
• Preconscious- ideas
that aren’t in your
awareness right now,
but you could easily
recall them- your stored
memories and
knowledge
• Unconscious- aka
Subconscioushidden from us- our
secret desires, urges,
fears, and impulses
(Freud was obsessed
with these)
• Nonconscious- basic
biological functions
(fingernails growing,
blood pumping)
DIFFERENT STATES OF CONSCIOUSNESS
•Sleep
•Meditation
•Hypnosis
•Drug Use
SLEEP
• Sleep is an altered state of
consciousness.
• We are less aware of our surroundings.
• Circadian Rhythm- the biological clock in
charge of our sleep/wake cycle

1. Describe the type of brain waves
2. Describe the characteristics of sleep at this stage.
3. Any interesting phenomenon that happen at this stage.
SLEEP CYCLE
• Use an EEG machine to
measure stages of sleep.
• Look at brain wave activity
during the different stages
• During an 8 hour night of
sleep people go through 5-6
sleep cycles
STAGE 1
• Kind of awake and kind of asleep.
(lightest stage of sleep)
• Only lasts a few minutes, and you
usually only experience it once a
night.
• Your brain produces Theta Waves
• You can have sudden wakefulnessfeels like you are falling
• Can have photographic images that
you easily recall if awakened- might
argue “I wasn’t asleep”
• Only lasts 1-7 mins
STAGE 2
• More Theta Waves
that get progressively
slower.
• Begin to show sleep
spindles…short bursts
of rapid brain waves.
STAGES 3 AND 4
• Slow wave sleep.
• You produce Delta waves.
• Stage 3- transitional, only in this
stage for a few minutes
• Stage 4 is the deepest level of
sleep
• If awoken you will be very groggy.
• Vital for restoring body’s growth
hormones and good overall health.
• Sleepwalking and bedwetting
occur in Stage 4
From stage 4, your brain begins to speed up and you
go to stage 3, then 2….then ……
REM SLEEP
• Rapid Eye Movement
• Stage 5- after about 90
mins of sleeping
• Blood pressure, heart beat
increase
• Brain is very active.
• Dreams usually occur in
REM.
• Body is essentially
paralyzed.

SLEEP DISORDERS
Disorder
Insomnia
Nightmares and
Night terrors
Sleepwalking
Sleep Apnea
Narcolepsy
Characterized by…
INSOMNIA
• Persistent problems
falling asleep
• Effects 10% of the
population
• Tend to suffer from
anxiety and “racing
minds” at sleep time
• Can come in cycles
NIGHT TERRORS
• Wake up screaming
and have no idea
why.
• Not a nightmare.
• Most common in
children (boys)
between ages 2-8.
SOMNAMBULISM
• Sleep Walking
• Most often occurs
during the first few
hours of sleeping and
in stage 4 (deep
sleep).
• Can do routine
activties
• If you have had night
terrors, you are more
likely to sleep walk
when older.
SLEEP APNEA
• A person stops breathing
during their sleep.
• Wake up momentarily,
gasps for air, then falls
back asleep.
• Associated with snoring
• Very common, especially
in heavy males.
• Can be fatal.
• People who have it are
usually very tired during
the day
NARCOLEPSY
Click above to see Skeeter the narcoleptic dog.
• Suffer from
sleeplessness and
may fall asleep at
unpredictable or
inappropriate times.
• Directly into REM
sleep
• Less than .001 % of
population.
DREAMS
FREUD’S THEORY OF DREAMS
• Dreams are a
roadway into our
unconscious.
• Manifest Content
(storyline)
• Latent Content
(underlying meaning)
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.
INFORMATION-PROCESSING THEORY
• Dreams are a way to
deal with the
stresses of everyday
life.
• We tend to dream
more when we are
more stressed.
HYPNOSIS
HYPNOSIS
• Altered state of
consciousness?
• Posthypnotic
suggestion
• Posthypnotic
amnesia
HYPNOTIC THEORIES
Role Theory
State Theory
• Hypnosis is NOT an
altered state of
consciousness.
• Different people have
various state of hypnotic
suggestibility.
• A social phenomenon
where people want to
believe.
• Work better on people
with richer fantasy lives.
• Hypnosis is an altered
state of consciousness.
• Dramatic health
benefits
• It works for pain best.
DISSOCIATION THEORY
• Theory by Ernest
Hilgard.
• We voluntarily divide
our consciousness up.
• Ice Water
Experiment.
• We have a hidden
observer, a level of
us that is always
aware.
DRUGS
DRUGS
• Our brain is
protected by a layer
of capillaries called
the blood-brain
barrier.
• The drugs that are
small enough to pass
through are called
psychoactive drugs.
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.
STIMULANTS
• Speed up body
processes.
• More powerful ones
(like cocaine) give
people feelings of
invincibility.
DEPRESSANTS
• Slows down body
processes.
• Alcohol
• Anxiolytics
(barbiturates and
tranquilizers)
ALCOHOL
• More than 86 billion
dollars are spent
annually on alcoholic
beverages.
• Alcohol is involved in
60% of ALL crimes.
• Alcohol is involved in
over 70% of sexually
related crimes.
• Is it worth the cost?
HALLUCINOGENS
• Psychedelics
• Causes changes in
perceptions of
reality
• LSD, peyote,
psilocybin
mushrooms and
marijuana.
• Reverse tolerance or
synergistic effect
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.
