Chapter 7 altered states of consciousness reviewAaron Carn
Rapid eye movement sleep, characterized by dreaming and muscle relaxation, is known as REM sleep. Hypnosis is a state of altered consciousness where people become highly suggestible. Marijuana is a psychoactive drug that interacts with the central nervous system to alter mood, perception, and behavior. Substances like LSD that produce hallucinations are called hallucinogens. Prolonged inability to sleep is called insomnia.
Consciousness refers to our awareness of ourselves and our environment, which varies depending on our attention. It describes what we are aware of, but many things are processed outside of our consciousness. Daydreaming and fantasizing are almost universal, and tend to serve adaptive functions like escaping reality, preparing for the future, and increasing creativity. Biological rhythms like circadian rhythms regulate our daily alertness cycles. Higher consciousness can be achieved through meditation and allows one to transcend normal thought patterns.

Biological rhythms influence our daily functioning through circadian rhythms and the sleep-wake cycle. The circadian rhythm is regulated by the suprachiasmatic nucleus which influences hormones like melatonin to make us feel sleepy. The sleep cycle consists of REM (rapid eye movement) and non-REM sleep stages that repeat about every 90 minutes. Sleep is important for restoration, recovery of the body, and processing memories from the previous day.
The document discusses consciousness and the sleep cycle. It describes three levels of consciousness: conscious, preconscious, and unconscious. The sleep cycle involves passing through stages of non-REM sleep (stages 1-4) and REM sleep in a repeating 90 minute cycle throughout the night. Stage 3 and 4 non-REM sleep involves slow wave brain activity that is important for restoration. REM sleep involves dreaming and brain activity similar to being awake but the body is paralyzed. Biological rhythms like the circadian rhythm influence sleep patterns on a daily cycle.
This document provides an overview of the nervous system and neural communication. It discusses that neurons communicate via electrical and chemical signals, transmitting information through the body.

Lesson 3 altered states of consciousness 2013Crystal Delosa
The document describes an exam question about a man named Roy who was learning words for a play in a room where a clock was ticking loudly. It asks two multiple choice questions:
1. Roy's ability to focus on learning the words despite the clock noise is best explained as a controlled process requiring mental effort.
2. It would be expected that Roy's thalamus directed his attention to learning the words while filtering out the sound of the clock.
The document provides context for a exam question about different levels of awareness and the role of the thalamus in directing attention and filtering sensory information.

Consciousness refers to awareness of one's own existence and mental experiences. Rene Descartes believed consciousness was non-physical and existed separately from the body, interacting via the pineal gland. William James likened consciousness to a constant flowing stream of thoughts, sensations and images. Both philosophers viewed consciousness as personal and ever-changing.
Unit 3 Freud and Consciousness Power PointMrTimBradley
According to Freud, dreams are a way for the unconscious mind to express wishes and desires that are censored from conscious thought. Dreams translate latent unconscious content into manifest content through processes like displacement, condensation, and the work of a censor. Analyzing dreams using free association could allow one to uncover the latent meaning behind the manifest dream narrative.
The document provides an overview of consciousness and related concepts through definitions, examples, and theories. It discusses consciousness as:
1) A mystery that modern science still aims to explain, such as how physical processes in the brain give rise to subjective experience.
2) A state of awareness that can be altered through different states of brain activity, perception, experiences like dreams, meditation, and altered states induced by drugs or sensory tricks.
3) A topic explored through different philosophical perspectives, such as dualism, functionalism, and theories that consciousness is an illusion or epiphenomenon of physical processes.
This document is from a psychology textbook and covers learning through classical and operant conditioning. It defines key concepts such as reinforcement, punishment, extinction, and conditioning. Classical conditioning links an unconditioned stimulus that naturally produces a reflex response to a conditioned stimulus through repeated pairings, resulting in the conditioned stimulus eliciting the reflex. Operant conditioning is learning through consequences of behaviors, where reinforcement increases behaviors and punishment decreases them.
This document is from a psychology textbook that introduces students to the field of psychology. It covers the history and evolution of psychology from its early structural and functional roots to modern perspectives like behaviorism, psychoanalysis, humanism, and cognitivism. Some key figures discussed include Wilhelm Wundt, Ivan Pavlov, Sigmund Freud, B.F. Skinner, Abraham Maslow, and Carl Rogers. The document also defines psychology as the scientific study of behavior and mental processes and outlines its goals of description, explanation, prediction, and control.
The document discusses several classes of sedative-hypnotic drugs including benzodiazepines, barbiturates, and other nonbarbiturate sedative-hypnotics. Benzodiazepines act by enhancing the effects of the inhibitory neurotransmitter GABA at GABA-A receptors and have a wide margin of safety. Barbiturates also enhance GABA effects but are no longer recommended due to their narrow therapeutic range and potential for abuse and dependence. Chloral hydrate is a relatively safe nonbarbiturate hypnotic used in some patient populations.
The document discusses different states of consciousness and levels of awareness. It describes dual processing and how information is processed both consciously and unconsciously.

Sleep is a naturally recurring state of reduced consciousness that is essential for restoration and repair of the body and brain. It occurs in distinct sleep cycles including light, deep, and REM sleep. Getting sufficient quality sleep provides many benefits like strengthening the immune system, improving mood and memory, and allowing the brain and body to repair damage. Disruptions to healthy sleep habits and practices can negatively impact physical and mental health. Maintaining a regular sleep schedule, relaxing before bed, and avoiding stimulants can promote better quality sleep.

People typically dream 4-5 times per night, with over 95% of dreams being forgotten. Dreams mainly occur during REM sleep, which accounts for around 90% of dreams. REM sleep increases throughout the night as sleep time increases. There are several theories about the meaning of dreams, including Freud's psychoanalytic theory that dreams reveal unconscious desires, the problem-solving theory that dreams have no inherent meaning but reflect how problems are processed, and Hobson and McCarley's activation-synthesis theory that dreams have no meaning and are simply a product of random brain activation during sleep. Researchers study dreams using sleep laboratories that can monitor physiological activity and brain waves during sleep.
This document discusses insomnia and normal sleep patterns. It provides details on:
1) The stages of the normal sleep cycle and how sleep needs change throughout life from childhood to older age.
2) Insomnia as a common sleep disorder defined by difficulties initiating or maintaining sleep that impairs daytime functioning.
3) Factors that can cause insomnia like medical conditions, medications, and psychiatric disorders.
4) Treatments for insomnia including sleeping pills, cognitive behavioral therapy, sleep restriction, stimulus control, and improving sleep hygiene.
This document provides information about sleep, including what sleep is, the sleep cycle, types of normal and abnormal sleep, and tips for improving sleep. Key points include:
- Sleep is a condition where the body and mind rest that typically occurs at night for 7-9 hours. It is essential for survival.
- The sleep cycle progresses through NREM and REM sleep stages roughly every 90 minutes over 4-5 cycles per night.
- Normal sleep means falling asleep within 20 minutes, sleeping 7-9 hours continuously, and waking feeling refreshed.
- Tips for better sleep include avoiding screens before bed, using yellow light, sticking to a schedule, and being in a dark, cool room.
Sleep serves important functions such as resting the body, reducing metabolism, strengthening memory, and rebuilding brain proteins. There are different stages of sleep including stages 1-4. Stage 1 is a light sleep where people can be easily awakened. Stage 2 is slightly deeper sleep. Stage 3 is deep slow-wave sleep important for restoration. Stage 4 is REM sleep where dreaming occurs and muscles are paralyzed. The amount and types of sleep change throughout life with babies and seniors requiring more total sleep than adults. Common sleep disorders include insomnia, sleep apnea, and nightmares.
This document provides an overview of sleep, sleep disturbances, and sleep disorders. It discusses the physiology and stages of normal sleep, including non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. It describes factors that affect sleep such as circadian rhythms, lifestyle, environment, and medications. Common sleep disorders are explained, including insomnia, sleep apnea, narcolepsy, and parasomnias. Diagnostic tests and treatments for sleep disturbances are also summarized.
This document summarizes sleep and circadian rhythms. It discusses that average healthy sleep is 7.5 hours and decreases with age. Circadian cycles regulate body temperature, growth hormone, and cortisol levels throughout the day and night. The suprachiasmatic nucleus contains a molecular clock that generates circadian rhythms in response to light signals from the retina. Melatonin production in the pineal gland increases at night and promotes sleep. There are four stages of non-REM sleep as well as REM sleep, which is characterized by rapid eye movements and desynchronized brain activity. Various brain regions and neurotransmitters regulate wakefulness, non-REM sleep, and REM sleep.
Consciousness refers to our awareness of ourselves and our environment, which varies depending on our attention. While conscious attention is focused on tasks, unconscious processes still occur. Daydreaming and fantasizing are common and may serve purposes like preparation, creativity, and stress relief. Biological rhythms like our circadian rhythm regulate sleep-wake cycles, with individuals varying as morning or evening types. Sleep occurs in stages including light, deep, and REM sleep, each with different brain wave patterns. Sleep serves functions like restoration and growth, and disorders can disrupt these functions.
The fund aims to provide financial support to small businesses and entrepreneurs who are just starting out or expanding their operations. It will offer loans and grants of up to $50,000 to eligible applicants looking to start a new business or grow an existing one. Priority will be given to applicants operating in rural areas, women-owned businesses, and businesses promoting environmentally sustainable practices.
Sleep is a cyclical physiological process that occurs in stages and is controlled by the brain. It consists of non-rapid eye movement sleep and rapid eye movement sleep in cycles of approximately 90 minutes. Non-REM sleep progresses through four stages from light to deep sleep while REM sleep involves rapid eye movements and vivid dreaming. Sleep serves the important functions of restoring physiological and psychological functions. Disturbances in normal sleep patterns can occur due to various lifestyle, environmental, medical and psychiatric factors.

Sleep occurs in stages that cycle throughout the night. Non-REM stages 1-4 involve light, then deeper sleep. REM sleep involves vivid dreaming. Disorders like insomnia prevent restful sleep, while sleep apnea involves pauses in breathing. Nightmares occur in REM sleep and involve fear, while night terrors happen in non-REM sleep with screaming but no memory. Lack of sleep can impair function and has contributed to disasters.
This document discusses the history and science of dreams. It explores theories about why we dream, where dreams come from in the brain, and the sleep cycle in which dreaming occurs. Several types of dreams are described like lucid dreams, nightmares, and recurring dreams. The document also covers facts about dreaming and the physical reactions that occur when we dream. In conclusion, it suggests that dreams can help solve problems and that achieving dreams requires being awake.
