CHAPTER 5 ConsciousnessCase Study: Biofeedback and ConsciousnessBiofeedback has shed some light on the nature of consciousness. BiofeedbackBiofeedback is a system for monitoring and feeding back information about certain biological processes.Biofeedback monitors show, for example, when a person’s heart rate is slower. ApplicationsBiofeedback helps people see how voluntary behavior affects involuntary behavior.Biofeedback is used to treat high blood pressure, seizures, migraine headaches, and digestive disorders.Section 1 at a GlanceThe Study of ConsciousnessConsciousness, like intelligence or emotions, is a construct; that is, it is a concept that cannot be seen, touched, or measured directly.Consciousness has a number of different meanings, including sensory awareness, direct inner awareness, and a sense of self.There are several levels of consciousness, including the preconscious, unconscious, and nonconscious.The Study of ConsciousnessMain IdeaConsciousness, the awareness of things that are both inside and outside of ourselves, is an elusive but essential subject of study for psychologists.Reading FocusWhy is consciousness a psychological construct?What are the general meanings of consciousness?What distinguishes the different levels of consciousness from full conscious awareness?-819150469903438525-762000What are you aware of right now?0What are you aware of right now?Consciousness as a ConstructConsciousness means the awareness of things that are both ____________ and ___________________ ourselves.Most psychologists believe consciousness can be studied even though it can’t be seen, touched, or measured directly – which means it’s a ________________Consciousness is known by its effects on _________________Meanings of ConsciousnessConsciousness as _______________ Awareness is sensory awareness of _________________________ (outside yourself) ex.

(sleep and hypnosis)Section 2 at a GlanceSleep and DreamsThe sleep cycle is made up of four stages of sleep and REM sleep.Sleep serves important physical and psychological mon sleep problems include insomnia, nightmares, night terrors, sleepwalking, sleep apnea, and narcolepsySleep and DreamsMain IdeaSleeping and dreaming are essential to human health, although many questions remain. Some people are troubled by various sleep problems.Reading FocusWhat is the sleep cycle?How have psychologists explored the importance of sleep and dreams?What are sleep problems?How did a dream become a classic horror story?The Sleep CycleMuch of how people, animals, and plants function is governed by _________________ rhythms, or biological clocks. (ex. – sleep-wake cycle)Circadian rhythms in humans include a sequence of bodily changes that occurs every ________ hours.The Stages of SleepDescribed in terms of ___________________ patterns.There are ________ stages of sleep.Stage ___ is the lightest stage of sleep.Stage ____ is the stage of deepest sleep.REM SleepAfter about 30 minutes of stage ___ sleep, we return to stage 3, then stage 2, and then stage 1 sleep.This takes about _____ minutes. Then another stage of sleep begins. It is called rapid-eye-movement sleep, or REM sleep. Beneath the closed lids, the _________ move rapidly.Stages of SleepStage 1 – lightest sleep, often see brief ____________ that resemble vivid photos. If awakened usually recall these images and feel as if we have ________ slept. (lasts no more than 30-40 minutes)We then move into stages 2, 3, and 4 which gradually take us into a deeper sleep with stage ____ being the deepest sleep. After about 30 minutes of stage 4 sleep we quickly go back to stage 3 then stage 2 then stage 1.We have now been asleep around 90 minutesWe start breathing more irregular, blood pressure _________, heart beat increases and we go into REM sleepDuring a typical 8 hours of sleep we would go through this sleep cycle about ___ timesThe Importance of Sleep and DreamsSleep revives the tired _______, builds up resistance to infection, helps recover from _________, helps consolidate memories.REM sleep seems to help animals and people ___________, remember, and retain ________________DreamsMost vivid during ____________ sleepDream in color and in __________ and _____________ Seem to dream in “___________ time.”Don’t always __________________ (hard to hold onto information from one state of consciousness to anotherThe Freudian ViewSigmund Freud theorized that dreams reflect a person’s unconscious ______________ and _______________Dream in ______________ as a way to deal with painful material they cannot otherwise deal with consciously.The Biopsychological Approach Biopsychologists believe that dreams begin with biological, not psychological, activity.(random ____________ bursts)According to this view, neurons fire during sleep. The neurons fire in the part of the brain that controls movement and vision. The brain tries to make sense of them by dreaming.Sleep ProblemsInsomniaInsomnia is the inability to ____________.most common is hard time _____________ asleep. (often have a racing mind, make it worse by TRYING to fall asleepMany psychologists believe that the best ways to overcome insomnia do not involve _______________They recommend using __________________ techniques, establishing regular bedtimes, and using pleasant _______________ to relax.

(nasal __________ helps)NarcolepsyNarcolepsy is when people suddenly fall asleep anywhere and _______________. (rare) (should not ___________) (fall into _____________ sleep)It is believed to be a genetic disorder of REM-sleep functioning.Current Research in PsychologySleep Deprivation in TeensLack of sleep affects both the mind and the body. Sleep deprivation can produce mental states of fatigue, drowsiness, and irritability. In addition, lack of sleep can contribute to physical symptoms such as weight gain, heart disease, and other symptoms and ailments. Teenagers who do not get enough sleep can also develop these problems.Studies show a link between lack of sleep and increased rates of obesity, diabetes, heart disease, high blood pressure, and stroke. Teenagers need 9.2 hours of sleep a night. Many high school students get less than 9.2 hours of sleep a night. Lack of adequate sleep puts teenagers at risk for weight gain, poor school performance, car accidents, alcohol abuse, and drug abuse.Starting school later might be one possible solution to insufficient sleep by teenagers.Section 3 at a GlanceAltered States of ConsciousnessAltered states of consciousness can be achieved while awake through biofeedback, meditation, and hypnosis.There are many myths surrounding hypnosis.Although there are controversies related to the use of hypnotism, hypnosis can be used to recall memories, reduce pain, and quit bad habits.Altered States of ConsciousnessMain IdeaA variety of techniques have been developed in order to achieve altered states of consciousness.Reading FocusHow do meditation and biofeedback work?What is hypnosis?How can hypnosis be used?

The methods for reaching these altered states of consciousness, however, are as diverse as the people who inhabit this planet.Australian Aborigines use ritual songs, dances, stories, and dreams to create the Dreamtime world. The Mevlevi use dancing to create an altered state of consciousness. They are known as whirling dervishes.The Hindu yoga school uses meditation to achieve an altered state of consciousness.Buddhists meditate to achieve a state of enlightenment called nirvana.The Inca in the Andean highlands of South America use a drug called yage to induce hallucinations.
