Drowsiness factors in to about 20% of all traffic incidents, as well as contributing to accidents in the workplace. Presentation Summary : Nature of Consciousness. Coma and altered consciousness 1. As you move into stages 3 and 4, which are called slow-wave sleep , delta waves become prominent. Consciousness includes four components: - Awareness of external events - Awareness of internal sensations - Awareness of the self as a unique being experiencing these events - Awareness of thoughts about the experience. The EEG records activity in the cortex with a series of brain-wave tracings that vary in amplitude and frequency. Circadian rhythms also produce periodic variations in alertness, body temperature, and hormonal secretion. Sleep deprivation is also linked to health problems, including obesity, diabetes, hypertension, and coronary disease. The possible health risks related to marijuana use have generated much debate in recent years. They also increase the risk of accidental injuries because they severely impair motor coordination. Academia.edu is a platform for academics to share research papers. This news clip shows how Americans are getting less and less sleep, as well as the effects of sleep deprivation on the brain. The desired effects are euphoria, relaxation, anxiety reduction, and reduced inhibitions.

Although sleep complaints escalate with age, much of this escalation is the result of increases in health problems that interfere with sleep. Conscious states are fundamentally different from anything else in nature because they are "subjective" and “opaque” (i can’t feel yours). Sedatives are sleep inducing drugs that tend to decrease central nervous system activation and behavioral activity. People have been deliberately trying to alter their consciousness since the beginning of human history. Consciousness is a whole, unlike the body which is made of parts, unlike everything else which can be decomposed into more and more elementary units. Cannabis is the hemp plant from which marijuana, hashish, and THC are derived.

Subsequent REM periods are longer, peaking at around 40 to 60 minutes. Levels of Awareness Subconscious (waking subconscious awareness, sleep, and dreams) Altered States of Consciousness (produced by drugs, trauma, fatigue, and other factors) Higher-Level (controlled processes and selective attention) No Awareness (unconscious thought) Lower-Level Stage 1 is a brief stage of light sleep in which theta waves are prominent. James Sully (1884) defined psychology as the “Science of the Inner World”. Physical dependence occurs when a person must continue to take a dug to avoid withdrawal illness, which can have a variety of symptoms depending on the drug. The nature of consciousness, its occurrence in the brain, and its ultimate place in the universe are unknown. Theorists believe that there are physiological reasons for both types of dependencies, centered on the “reward pathway” in the brain. Decades of research have shown that virtually all mammals and birds exhibit REM sleep. There is no risk of physical dependence on marijuana, however there is a chance of becoming psychologically addicted.

Drugs are used recreationally for pleasurable alterations in consciousness. Amphetamines also affect dopamine and norepinephrine synapses by increasing the reuptake of neurotransmitters by presynaptic neurons and slowing the process of reuptake. Sleep disorders are quite varied. Recent research has suggested that the primary cause of insomnia may be that some people are predisposed to insomnia because they have a higher level of physiological arousal than the average person. In the Paralogisms of The Critique of Pure Reason, Kant comes to terms with this dialectic, and with the character of the experiencing self. Alcoholism is associated with a diverse array of physiological maladies, such as liver disease, malnutrition, brain damage, neurological disorders, heart disease, stroke, hypertension, ulcers, cancer, and birth defects. But the word ‘mind ‘ is also quite ambiguous as there was confusion regarding the nature and functions of mind. COMA AND ALTERED CONSCIOUSNESS 2.

REM sleep is the stage of sleep during which most dreaming occurs. [click] Notice how body temperature drops when people fall asleep. As a result, more neurotransmitters are available to bind at receptor sites, causing more postsynaptic potentials, and greatly increasing activity at these synapses. We proposed in the mid 1990's that consciousness depends on biologically 'orchestrated' quantum computations in collections of microtubules within Clipping is a handy way to collect important slides you want to go back to later. This video shows a few possible treatments that can be used for jet lag, with varying efficacy. The most common, however, is insomnia . Overdose potential - known as alcohol poisoning - varies. Looks like you’ve clipped this slide to already. These daily cycles are particularly important in the regulation of sleep. The Nature of Consciousness book. Common side effects include lethargy, nausea, and impaired mental and motor functioning. The use of cocaine or amphetamines can eventually lead to a depletion of dopamine and norepinephrine, which appears to be the cause of the emotional crash after the effects wear off. I is an article from The Journal of Philosophy, Psychology and Scientific Methods, Volume 9. As the night wears on, the cycle gradually changes. Babies get far more REM sleep than do adults - about 50% of their total sleep is spent in REM. 1. por | Dic 27, 2020 | Uncategorized | 0 Comentarios | Dic 27, 2020 | Uncategorized | 0 Comentarios We know now that people dream in non-REM too, although the dreams are less story-like and vivid in imagery. We all know what it means to be conscious, and we assume (although we can never be sure) that other human beings experience their consciousness similarly to how we experience ours. [Click to continue] During stage 2, brief bursts of higher-frequency brain waves, called sleep spindles, appear against a background of mixed EEG activity. Nature of Consciousness. Human beings have used meditation, medication, religious rituals, sleep deprivation, and numerous other means to alter their levels of everyday awareness. Other sleep issues are sleep apnea, which involves frequent, reflexive gasping for air that awakens a person and disrupts sleep; and REM sleep behavior disorder (RBD), which is marked by potentially troublesome, dream enactments during REM periods. Insomnia occurs in 3 different patterns…trouble falling asleep, trouble remaining asleep, and persistent early morning awakening. Research shows that the content of dreams is usually familiar. In addition, researchers have examined experienced meditators and found that they had significantly more gray matter (than control subjects) in several regions of the brain. The experience of consciousness is fundamental to human nature. THC, the active chemical ingredient, causes a mild, relaxed euphoria and enhanced sensory awareness. Risks associated with marijuana use include accidents, lung cancer, respiratory disease, pulmonary disease, and increased vulnerability to psychosis. When people drink heavily, the effect is a relaxed euphoria that temporarily boosts self-esteem and decreases inhibitions. Neuroscientists of the20th century who were looking for consciousness missed that simple syllogism:they were looking for consciousness using a tool that was labeled "this tooldoes not find consciousness".

In its narrow sense, curriculum is viewed merely as a listing of subject to be taught in ... cultural consciousness, moral integrity and Functionalism is a theory about the nature of mental states. Research suggests that the effects of sleep deprivation are impaired attention, reaction time, cognitive speed and accuracy, motor coordination, and decision making. In old age, the proportion of light sleep increases and there is an increased frequency of nighttime awakenings. Phenomena that can be produced through hypnosis are many, including experiences such as anesthesia during medical or dental procedures, hallucinations (seeing, hearing, feeling, tasting, or smelling something that is not there), disinhibition (doing things you would normally be more inhibited about doing, like taking off your clothes in public), and posthypnotic suggestions and amnesia- influences of suggestions made during the hypnosis session on subjects’ later behavior (“you will remember nothing that occurred during your hypnotized state”). Is consciousness an outgrowth of the physical brain -- or is it something more fundamental, perhaps the primary substance of reality? 4 The Nature of Consciousness acquaintances, for example – who, I think they will not mind me saying, are very definitely not in the grip of some quite specific theory of the mind – indicates that they at least seem to have no difficulty in under- Upcoming SlideShare. Natural Resources • Intangible Resources – Good Health, Knowledge Resource does not refer to a thing or substance, but to a function which a thing or substance may perform to attain an end. Freud noticed that the contents of waking life tend to spill into dreams; he called this day residue . Sedatives also have high rates of dependence and fatal overdose potential. This clip shows how gender affects alcohol metabolism as well as the self-perception of intoxication vs. actual level of intoxication. By definition, Descartes dualism predicts that "mind" cannot beexplained from matter, and Newtons Physics is basically an instantiation ofDescartes’ dualism. Dreams are conventionally defined as mental experiences during REM sleep that are often based in vivid imagery, have a storylike quality, are often bizarre, and seem real to the dreamer. Consciousness includes four components: - Awareness of external events - Awareness of internal sensations - Awareness of the self as a unique being experiencing these events - Awareness of thoughts about the experience ; Measuring variations of consciousness has historically been done by an electroencephalograph, or EEG. Modern psychologists defined psychology as the “Science of Consciousness”. The euphoria created by these drugs is very different from the “who cares,” very relaxed state of narcotics - more like an “I can conquer the world,” very alert state of being. Also, recent research shows that content is usually not bizarre, and that dreamers are often aware that they are dreaming. Nature of globalization 1. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Approaches to meditation can be classified into two main styles that reflect how attention is directed: focused attention or open monitoring. Investigators have found that REM sleep appears to foster the recently discovered process of neurogenesis. As a result, neurotransmitter molecules pile up, causing increased postsynaptic potentials. Psychologist and author Stanley Krippner identified more than 20 states of altered consciousness. Read 22 reviews from the world's largest community for readers. Many recent theorists have, however, questioned almost every aspect of this definition. The first REM period is relatively short. The final monologue of Molly Bloom in the ‘Penelope’ chapter is one of the salient instances of Joyce’s use of stream of consciousness technique.

No surprisethat it derived a view of the brain as a set of mechanical laws: that is the"only" view that classical Physics can derive. Studies have demonstrated that circadian rhythms generally persist even when external time cues are eliminated. Hypnosis is a systematic procedure that typically produces a heightened state of suggestibility as well as relaxation, narrowed attention, and enhanced fantasy. See our User Agreement and Privacy Policy. 1. Meditation results in a potentially beneficial physiological state whereby bodily arousal is suppressed, but it is unclear how meditation differs from other systematic relaxation training procedures which produce very similar effects. Exposure to light apparently affects the activity of a small structure in the hypothalamus called the suprachiasmatic nucleus, which sends signals to the nearby pineal gland, whose secretion of the hormone melatonin plays a key role in adjusting biological clocks.

William James (1892) defined psychology as the science of mental processes. Consciousness 1. Psychological Construct A psychological construct refers to a concept that is constructed to described a specific psychological activity that is believed to exist but cannot be directly observed. It is a psychological state that has a "causal" nature. Cocaine exerts its effects at the norepinephrine and dopamine synapses by interfering with reuptake at these locations. From Rene Descartes to David Hume, philosophers in the 17th and 18th centuries developed a dialectic of radically conflicting claims about the nature of the self.

Other risks include sleep problems, malnutrition, nasal damage (from snorting), hypertension, respiratory disease (from smoking), strike, liver disease, and heart attack. EEG activity during REM sleep is dominated by high-frequency beta waves that resemble those observed when people are awake and alert. Additionally, non-REM intervals tend to get shorter, and descents into non-REM stages usually become shallower. Brain wave activity is divided into four different bands; beta waves, which are correlated with alertness and problem solving; alpha waves, which are correlated with resting and relaxation; theta waves, which are correlated with low alertness and sleep; and delta waves, which are correlated. Meditation is an ancient discipline which has recently become an area of growing interest. Seleccionar página. The Analysis Of Culture Raymond WilliamsMETU Faculty of Architecture Department of Industrial DesignID501 Advanced Project De… In “Mechanisms of Consciousness”, Keller proposes an objective way of evaluating mechanistic theories of consciousness by testing how well the proposed mechanism correlates with the occurrence of conscious processes. Other risks include infectious diseases (through sharing of needles), accidents, and immune suppression. The Nature of Consciousness What is consciousness? Our conscious awareness represents that … Consciousness is defined as our subjective awareness of ourselves and our environment (Koch, 2004). No surprise that it could notexplain how consciousness arises, since there is no consciousness inclassical Physics: it was erased from the study of matter by Descartesdualism (that mind and matter are separate), on which foundations Newtonerected classical Physics (the science of matter, which does not deal withmind). Alcohol is the most widely used psychoactive drug. Actually, those being hypnotized may have trouble distinguishing between memory and fantasy, and may have an artificially inflated confidence about what they “remember.” Other misconceptions include the idea that one must be relaxed to be hypnotized, hypnotized people lose control of themselves, and the idea that hypnosis can enable people to perform otherwise impossible feats. See our Privacy Policy and User Agreement for details. Psychoactive drugs modify mental, emotional, or behavioral functioning. What I want to do in this book is take a critical look at philosophical attempts to tell us what consciousness really is while remaining, if possible, within the bounds of the modern descendant of Descartes’s scientific picture of the world.
