ALTERED STATES OF CONSCIOUSNESSAP Psych, Myers – Ch. 7

“His was a great sin who first invented

consciousness. Let us lose it for a few

hours.”F. Scott Fitzgerald

CONSCIOUSNESS

Our awareness of ourselves and our environment (constantly processing information)

• Slow, sequenced• Limited capacity• Good at problem

solving

Conscious Processing

• Fast• Parallel tracks

simultaneously

Unconscious

Processing

ALTERED STATES OF CONSCIOUSNESS

Consciousness is a continuum ranging from alertness to unconsciousness.

FREUD’S STATES OF CONSCIOUSNESS

Conscious Perception, thoughts

Preconscious Memories, stored

knowledge Unconscious

Unavailable/hidden Repressed memories,

dangerous/sexual desires

Protection from anger, guilt, shame

SLEEP“I love sleep. My life has the tendency to fall apart when I’m awake, you know?”

- Ernest Hemingway

BIOLOGICAL RHYTHMS

Periodic physiological fluctuations controlled by your “biological clock”

Circadian rhythm - regular bodily rhythms that occur in a 24-hour period

CIRCADIAN RHYTHM – FUN FACTS

Light processed by retina triggers brain to increase/decrease production of melatonin

Can be disrupted/reset by adjusting sleep schedule Jetlag, sleeping in late, etc

Artificial light delays sleep 25-hour circadian rhythm The 24 hr sleep cycle is a product of

industrialization and constant artificial light

SLEEP STAGES

Sleep - periodical, natural, reversible loss of consciousness

5 Stages (90 min cycles) 1 2 3 4 REM

Awake/relaxed Just before you fall asleep Alpha waves

STAGE 1

Slowed breathing, irregular brain waves (typical of unremembered moments)

Sleep talking can occur

Hallucinations – sensory experiences that occur without sensory stimuli feeling of free falling to

be awoken by a jerk

STAGE 2

20 minutes into sleep cycle Periodic appearance of sleep spindles (bursts

of rapid, rhythmic brain wave activity)

STAGE 3

Lasts only several minutes

Begin to produce large delta waves – the large, slow brain waves associated with deep sleep

Hard to awaken

STAGE 4

Combined with stage 3 to last about 30 minutes

Delta waves – deep sleep

Hard to awaken At the end,

sleepwalking or bedwetting or night terrors may occur.

REM SLEEP

REM sleep – rapid eye movement sleep, a recurring sleep stage during which dreams commonly occur

Occurs about an hour into sleep cycles

Ascend through stages 4, 3, 2.

Sharp, short brain waves – look like waves of stage 1

REM SLEEP

Heart rate and breathing rise Eyes dart around behind the lids Motor cortex is active, but blocks movement

messages – essentially paralyzed – paradoxical sleep

Gets longer throughout the night Easier to immediately slip into if awoken towards

the morning Hallucinatory dreams – vivid, story-like

SLEEP STAGES

WHY SLEEP?

Not everyone needs 8 hrs (newborns vs teens vs adults)

Unhindered = 9 hrs

SLEEP THEORIES

Protection evolutionary

Recuperation body and brain

Memory Shed unimportant info, strengthen important info

Growth Growth hormone – babies sleep more

AM I SLEEP DEPRIVED? – TRUE OR FALSE

1. I need an alarm clock in order to wake up at the appropriate time.

2. It’s a struggle for me to get out of bed in the morning.3. Weekdays mornings I hit the snooze button several times to get

more sleep.4. I feel tired, irritable, and stressed out during the week.5. I have trouble concentrating and remembering.6. I feel slow with critical thinking, problem solving, and being

creative.7. I often fall asleep watching TV.8. I often fall asleep after heavy meals.9. I often fall asleep within 5 minutes of getting in bed.10. I often fall asleep while relaxing after dinner.11. I often fall asleep in lectures or warm rooms.12. I often sleep extra hours on weekend mornings.13. I often need a nap to get through my day.14. I have dark circles around my eyes.15. I often feel drowsy while driving.

3+ T’s = YOU NEED

MORE SLEEP!

SLEEP DEPRIVATION Depression Increase likelihood of accidents Decreased alertness Decreased concentration Irritability

SLEEP DISORDERS - INSOMNIA

Recurring problems in falling/staying asleep

Natural and drug treatments

SLEEP DISORDERS - NARCOLEPSY Uncontrollable sleep

attacks by falling into REM sleep at inappropriate times ~5 min 1 in 2,000 Brain malfunctions

Underproduction of neurotransmitters that signal alertness

Reticular formation Medication can help

SLEEP DISORDERS – SLEEP APNEA

Temporary cessations of breathing during sleep and repeated momentary awakenings 1 in 20 Typically overweight men Irritability due to awakenings

Treatment - weight loss or mask that pumps air to keep airway open

SLEEP DISORDERS – NIGHT TERRORS

High arousal and an appearance of being terrified Stage 4, not REM (like nightmares) Intense fear, panic, and movement Mostly in children

Sleep Infographic

DREAMS“Dreaming is a phenomenon of purely individual consciousness, and consequently impossible to thoroughly deconstruct by a community of researchers. BUT dreaming matters.”

-Andrew Weil

DREAMS

Sequence of images, emotions, and thoughts during REM sleep

Lucid dreaming – awareness of dreaming while dreaming

Modern theories: Information processing (to file away memories) To develop/preserve neural pathways. Activation synthesis theory (to make sense of

random neural static)

FREUD’S DREAM THEORY We dream to satisfy unconscious

wishes and desires Manifest content – the

remembered storyline of a dream Latent content – the underlying

meaning of a dream Unconscious drives and wishes that

would be threatening if expressed directly

Freud – dreams are the key to understanding the unconscious

Modern scientists – Unscientific, everyone can interpret dreams differently

and 14.2. Then add all values for the 14 questions.3. Scores can range from 14 to 98. 4. Higher scores reflect more positive attitudes toward

asthma No – does not help addictions to alcohol, drugs,

FAQ - HYPNOSIS

Can hypnosis alleviate pain? Yes – hypnotized patients in surgical experiments

were found to require less medication, recover sooner, and leave the hospital earlier than nonhypnotized patients

Inhibition of pain-related activity
