Our awareness of ourselves and our environmentb. Alertnessc. Self-awarenessd. Mental content, thoughts, and imaginingse. Formsi. Spontaneously1. Daydreaming2. Drowsiness3. Dreamingii. Physiologically induced1. Hallucinations2. Orgasm3. Food or oxygen starvationiii. Psychology induced1. Sensory depravation2. Hypnosis3. Meditationf. Driving Consciousnessi. Drivers are 4 times more likely to have an accident when talking on a cell phoneii. Driving while on the phone is the same as driving with a Blood alcohol level at the legal limitiii. Increased risk of accident from cell phone usage due to loss of concentration from engaging in conversationg. Multitaski. Consciousness changes throughout the dayii. “to do two things at once”II. Daydreaminga. More likely to occur when they are boredb. Prone to daydream when they are engaged in instructed activitiesc. Involve mundane tasks of everyday lifed. Form of consciousness that occurs during a waking stateIII. Rhythms and sleepa. Circadian Rhythmi. The body’s natural 24 hour cycle, roughly matched to the day/night cycle of light and darkb. Changes in 24 hour periodi. Body tempii. Arousal/energyiii. Mental sharpnessc. General Alertnessi. Evening peak- 20 year oldii. Morning peak- 50 year oldIV. Circadian Rhythmsa. Occur on a 24-hour cycle and include sleep and wakefulness. Our “biological clock,” can be altered by artificial light.b. Time shifting can wreak havoc on circadian rhythmsc. Light entering though the eye help keep the body clock in sync with day and nightd. Body temp follows a circadian rhythm in which temp falls a few degrees during the idle of the nighte. Found in almost all species, even paramecia and trees.V. Unconsciousnessa. We move around, but stop ourselves from falling out of bedb. Incorporate real world noisesc. Some noises wake us more easilyd. Monitoring sleepi. EEGii. Brain wavesiii. Muscle movementsiv. Expose v. Wake peopleVI. Sleep stages and cyclesa. Sleep Stagesi. Determine patterns of brain waves and muscle activity associated with different types of consciousness and sleepii. 4 types of sleepb. Sleep cyclesi. Patterns of shifting through all the sleep stages over the course of the nightii. The sleep stages in about 90 minutes on averagec. Alpha wavesi. Relatively slow brain waves of a relaxed, awake stated. Falling Asleepi. Yawning makes a brief boost in alertness as your brain metabolism is slowing downii. Breathing slows downiii. Brain waves become slow and irregulariv. Hypnagogic hallucinationsv. Brain waves change from alpha waves to NREM-1e. REM Sleep: stage 5i. Dreams occurred during periods of wild brain activity and Rapid Eye Movements.ii. Heart rate rises and breathing becomes rapidiii. Sleep paralysis occurs when the brainstem blocks the motor cortex’s messages and the muscles don’t move. Also known as paradoxical sleep; brain is active but immobileiv. Genitals are arousedv. Increases the longer you remain asleepvi. With age there are more awakenings and less deep sleepVII. Reasons we Sleepa. Agei. Newborns need 16 hoursii. Adults need 8b. Individual variationc. Cultured. Circadian rhythm is hard to ship- jet lagi. Affected by lighte. Protectionf. Restores and repairsg. Strengthens memoriesh. Facilitates creative problem solvingi. Growth hormonesj. Sleep Deprivationi. Fatigueii. Impaired concentration memory, problem solvingiii. Irritabilityiv. Depressed immune systemv. Vulnerabilityvi. Slow reaction timesvii. Slow learning informationviii. Impaired academic performanceix. Accidentsk. Effects body systemi. Brain1. Slow attention focus and increased risk in depressionii. Immune system1. suppressediii. Fat cells1. Greater risk of obesityiv. Jointsv. Heart1. Risk of high blood pressurevi. Stomachvii. MusclesVIII. Dreamsa. Often include negative event or emotion, FAILURE Dreamsb. Do not often include sexualityc. Incorporate real world sounds and other stimuli into dreamsd. Why we dreamIX. Theories of Dreama. Wishfulfillmenti. Express unacceptable feelingsX. Sleep Disordersa. Insomniai. Inability to fall asleep or stay asleepii. Problem sleep habits lead to insomniaiii. Caused by depressioniv. Caused by substance abusev. Prevents people from achieving restorative sleepb. Narcolepsyi. Sleep attacks even a collapse into REM/ paralyzed sleep at inopportune timesc. Sleep apneai. Repeated awakening after awakening after breathing stopsii. Caused by structural defects in the mouth or throatiii. May stop breathing as many as five hundred times a night during sleepiv. Approximately 18 million Americans suffer from sleep apneav. Increased risk of stroke and hypertensiond. Night terrorsi. Sudden scared-looking behavior with rapid heartbeat and breathingii. Occur in stage 4e. Sleepwalking/ sleeptalkingi. Run in familiesii. Affect mostly children and occur in NONREM-3 sleep.iii. Considered not dreamingiv. Stage 4v. Harmless and unrecalled the next dayvi. Can have accidents during their nighttime wanderingsXI. Sleeping wella. Dim lights and turn screens offb. Eat earlier and drink less alcohol and caffeinec. Get up at the same time everyday, avoid napsd. Exercise regularly, not in late eveninge. Don’t check the clockf. Manage
