Transcript of consciousness and altered state

Consciousness and Altered State Consciousness Two Functions of Consciousness Two Areas of Consciousness - are specific memories of personal events as well as the information collected over a lifetime and these memories are accessible to consciousness. Preconscious Memories refers to a level of mental activity that contains unacceptable memories, impulses (sexual and aggressive), and desires of which the individual is unaware. Unconscious is the awareness of various cognitive processes that operate in daily lives: making decisions, remembering, daydreaming, concentrating , sleeping, dreaming among other. Waking Consciousness ~ includes the thoughts, feelings, and perceptions that rise when awake and reasonably alert. Altered State of Consciousness ~ during which or mental state differs noticeable from normal waking consciousness if one is under hypnosis, under the influence drugs, and day dreaming or dreaming. Monitoring ~ one main function of the body's sensory systems, oneself and the environment so that what is perceived, what is remembered and what is thought are represented in awareness. Controlling ~ another function of consciousness, oneself and the environment to be able to start and stop behavioral and cognitive activities. ... small e.g. playing basketball, driving a car or texting. Automaticity - the habituation of responses that initially required conscious attention, it becomes automatic. - the more the automatic an action becomes, the less it requires conscious control. Freudian Slip ( Parapraxes ) Sigmund Freud believed that some emotionally painful memories and wishes are repressed-- that is, diverted to the unconscious, where they may continue to influence actions even if they are not aware of it (Bernstein 2010). is commonly used to refer to unintentional remarks that are assumed to reveal hidden impulses. Sleep Circadian Cycle: The Biological Clock is a naturally recurring state characterized by reduced or absent consciousness, relatively suspended sensory activity, and inactivity of nearly all voluntary muscles. is a regular biological rhythm with approximately a 24 hour period. is the largely governed by a tiny cluster of neurons in the lower region of the hypothalamus known as the Suprachiasmatic nucleus (SCN). What is Sleep
Why Does People Sleep? The Restoration-and-Recovery Theory Dr. Picar (2010) a person sleeps to restore bodily functions in terms of repair and regeneration, because metabolic system decreases when he is asleep," Low metabolic rate appears to facilitate bio synthesis. Sleeping restocks the energy reserve to maintain wakefulness and be efficient the next day. Stages of Sleep Stage 1 the state of transaction between wakefulness and sleep, characterized by relatively rapid, low amplitude brain waves. (Lightest Sleep) stage lasts a few minutes. person is easily aroused by sensory stimuli such as noise. If awakened, person feels as though daydreaming has occurred. Stage 2 (Sound Sleep) it is characterized by a slower more regular wave pattern, along with momentary interruptional of sleep spindles (brief bursts of 12-16 hertz waves) and K-complexes (a sharp rise and fall in the brainwave pattern). relaxation progresses. arousal is still easy. stage lasts 10 to 20 minutes. body functions continue to slow. Stage 3 (Deep Sleep) sleep characterized by slow brain waves with greater peaks and valleys in the wave pattern than in stage 2. presence of 20-50% of delta waves. sleeper is difficult to arouse and rarely moves. muscles are completely relaxed. vital signs declines but remain regular and lasts 15 to 30 minutes. Stage 4 (Deepest Sleep) it is very difficult to arouse sleeper. presence of 50% or more delta waves. if sleep loss has occurred, sleeper will spend considerable portion of night in this stage. stage is responsible for restoring and resting body. stage lasts approximately 15 to 30 minutes. sleepwalking and enuresis may occur. CHAPTER 5 Neonates sleeps with a range of 10 to 23 hours with an average of 16 hours of sleep a day. sleeps almost constantly for the first week of life to recover from birth. Toddlers toddlers sleep average is 12 hours a day, naps may be eliminated at 3 years. by age 2, they usually sleep through the night and take daily naps. Preschool Children an average sleep of a preschool child is about 12 hours a night and rarely takes naps. has problems with bedtime fears, waking during the night, or nightmares. School-Aged Children a 6-year-old averages 11 to 12 hours of sleep nightly, whereas an 11-year-old sleeps about 9 to 10 hours. the amount of sleep varies depending on the activity and levels of health of the child. Adolescents averages 8 to 9 hours of sleep a night. an adolescent's day is usually active and mentally and physically exhausting. Young Adults average of 6 to 8 hours of sleep a night, but this can vary. It is not usual for young adults to take regular naps. healthy young adults require rest and sleep to participate in the busy activities that fill their days. Middle Adult the total time spent sleeping at night begins to decline. the amount of stage 4 sleep begins to fall, continuing throughout older age and sleep disturbances are common. Older Adults Narcolepsy Sleep
Talking Night Terrors Apnea Periodic Limb Movement Disorder Insomnia is a characterized by difficulty in falling asleep or remaining asleep throughout the night. is marked by breathing difficulties during the night and feeling of exhaustion during the day. is a hereditary sleep disorder characterized by sudden nodding off during the day and sudden loss of muscles tone following moments of emotional excitement. this characterized by repeated involuntary movement of the legs and sometimes the arms. are experience of intense anxiety from which a person awakens screaming in terror. is a sleep disorder defined as talking during sleep without being aware of it. Sleep talking can involve complicated dialogues or monologues, complete gibberish or mumbling. Sleepwalking is a behavior disorder that originates during deep sleep and results in walking or performing other complex behaviors while asleep. Sleep Disorders Neonates sleeps with a range of 10 to 23 hours with an average of 16 hours of sleep a day. sleeps almost constantly for the first week of life to recover from birth. Toddlers toddlers sleep average is 12 hours a day, naps may be eliminated at 3 years. by age 2, they usually sleep through the night and take daily naps. Preschool Children an average sleep of a preschool child is about 12 hours a night and rarely takes naps. has problems with bedtime fears, waking during the night, or nightmares.

Middle Adult the total time spent sleeping at night begins to decline. the amount of stage 4 sleep begins to fall, continuing throughout older age and sleep disturbances are common. Normal Sleep Requirements and Patterns Older Adults quality of sleep deteriorates and there is a progressive decrease in stage 3 and 4 NREM, and an older adult has almost no stage 4 sleep. an older adult awakens more often during the night, and total wake time increase. Characteristics of ASC change in perception and attention. change in memory functioning. change in higher level of thought processes. change in emotional feelings and self control. Rapid Eye Movement sleep occupying 20% of an adult's sleeping time. it is typified by autonomic response of rapidly moving eyes, fluctuating heart and respiratory rates, and increased or fluctuating blood pressure. stage usually begins every 50 to 90 minutes after sleep has begun. loss of skeletal muscle tone occurs and gastric secretions increase. this stage is responsible for mental restoration and it is very difficult to arouse sleeper, duration of REM sleep increases with each cycle and averages 20 minutes. Sleep Dreaming What is Dreaming? What are the Meanings of Dreams Group Meaning of Dreams Group 2 Thank you for Watching :) Cartwright: dream as information processing Crick and Mitchison: Meaningless Dreams Freud: symbolic and disguised dream Hobson: transparent and unedited dreams (cc) photo by theaucitron on Flickr (cc) photo by theaucitron on Flickr Dreaming wish-fulfillment no real significant. by product of stimulation. Freud conceptualized dreams as arising from unfulfilled needs. dream is the fulfillment of the unfulfilled need it can also be important in understanding unconscious motivation. they are also meaningful, undisguised and often rich in conflictual impulses. content of dreams has a little or no meaning. Dreams are important to reduce fantasy and obsession in the waking state. dream content exhibits consistent, patterns from night to night and within single. Aldryne John Manuel
