Measuring sleep activity




• There are 4 stages of quiet sleep and 1 stage of active sleep

• Approx. 75% of sleep time is spent in stages 1 thru 4

• Approximately 25% of sleep time is spent dreaming

• Electroencephalograph (EEG) and other devices are used to measure sleep activity


• Stage 1• Pulse slows• Breathing uneven• Muscles relax• Twitching• Eyes roll / visual images• Sensation of “drifting”• Lasts about 10 minutes



• Stage 2:• Slower brain waves• Eyes move slowly from side-to-side• Lasts about 30 minutes



Stage 3:Stage 3:• Deeper sleep• Large delta brain waves every few seconds• Varies in length



Stage 4: • State of oblivion• Delta brain waves 50% of the time• Varies in length• Sleepwalking• Bed wetting• Talking out loud



REM Sleep(Rapid Eye Movement): (dreaming) cycles in and out after stage 4

• Irregular breathing/pulse• Adrenal and sex hormones increase• “Awake” brain wavesoccur every 90 for 10

Effects of Sleep Loss fatigue impaired concentration depressed immune

system greater vulnerability to

accidents


Sleeping and Dreaming• Dreams get longer throughout the night with the last one the most likely to be remembered• Dreams have a purpose according to many psychologists but they disagree on what it is• Sigmund Freud: First to thoroughly study dreams believing they fulfilled hidden wishes• Manifest Content of dreams comes from the re-living of the day’s events in your dreams• Latent Content of dreams comes from repressed unconscious desires, often of a sexual nature

Section 7Q2Hypnosis …Hallucinations …Meditation


• Hypnosis: Characterized by a narrow focus of attention and heightened suggestibility

• Hypnotic trance is not sleep, but rather a loss of interest in external distractions

• Subject must be willing to cooperate, and will only do things they normally would do

• Dissociation Theory Vs. Hidden Observer Theory


Dissociation Theory of Hypnosis

• State of subconscious control through focusing

• Certain thoughts, emotions, sensations, and/or memories are separated “out” by your mind

• Can also be reached thru traumatic accidents/events

• Examples:

• Post Traumatic Stress Disorder

• Dissociative Identity Disorder (DID)

• Formerly Multiple Personality Disorder


Hidden Observer Theory of Hypnosis

• When under hypnotic control, awareness of the world around you isn’t “off” – just merely separate

• Person may be “aware” of actions but not have any idea why the action is taking place or how

• How those actions take place is through the “hidden observer”, who is like an autopilot for your mind


• Posthypnotic Suggestion: Hypnotist gets subjects to do things after trance has ended … normally for treatment of a psychological condition

• Smoking cessation, anxiety relief, weight loss etc.

Non-hypnotized persons can also do this


:Perceptions that have no direct external cause and are not input from the senses

• Causes include hypnosis, meditation, some drugs, addiction withdrawal, psychosis

• Detect increase Dopamine levels in the brain

• Hallucinations are very similar from one person to the next due to brain’s reaction


• Sensory Deprivation: Severely limiting sensory inputs to a person’s brain

• People quickly become irritable, restless, upset and some begin to hallucinate

• Biofeedback: Learning to voluntarily control autonomic nervous system processes with the help of feedback

• Scientists used to believe heart rate, blood pressure, sweating etc. were involuntary


• Meditation: Focusing attention with the goal of clearing the mind to gain “inner peace” (self-hypnosis)

• Mantra: Special word that is repeated over and over causing deep relaxation response

• The Four Elements of Meditation; Quiet, Comfortable, a “Mental Device” (Mantra), & Passive Attitude
