Selective attention A teenager testing while crossing the street is not likely to notice a car rounding the corner and about to cross her path. This best illustrates the impact of selective attention The focusing of conscious awareness on a particular stimulus Circadian rhythm the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle. Sleep Apneas a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings.
Most commonly associated with obesity ERM paid eye movement sleep, a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active. A recurring sleep stage during which most vivid dreams commonly occur Alcohol consumption disrupts the processing of recent experiences into long-term memory by decreasing ERM sleep ERM rebound the tendency for ERM sleep to increase following ERM sleep deprivation (created by repeated awakenings during ERM sleep).
Change blindness Failing to notice changes in the environment NORM stages Activity increases from stages 1-3 NORM-3: Sleepwalking is most likely to be associated with this stage gherkin Sleep deprivation increases levels of this hunger-arousing hormone Oregon Narcolepsy is associated with a relative absence of a hypothalamic neural center that produces this hormone Lepton Lepton, a hormone secreted exclusively by adipose cells in response to an increase in body fat mass, is an important component in the regulation of long-term hunger and food intake.
Lepton serves as the brain’s indicator of the body’s total energy stores Fraud’s Wish-Fulfillment horror of dreaming that states that dreams provide a “psychic safety valve”- expressing otherwise unacceptable feelings The distinction between manifest content and latent content is central to this theory of dreams Latent Content according to Freud, the underlying meaning of a dream (as distinct from its manifest content). Manifest content according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content).
Physiological Theory of Dreams theory of dreaming that states that the regular brain stimulation from ERM sleep may help develop and preserve neural pathways Dissociation split in consciousness, which allows some thoughts and behaviors to occur simultaneously with others. Has been an explanation for hypnotic pain relief. Information processing theory of dreams theory of dreaming that states that dreams help us sort out the day’s events and consolidate our memories Near death experience an altered state of consciousness reported after a close brush with death (such as through cardiac arrest); often similar to drug-induced hallucinations.
Hallucinations similar to those that accompany the near-death experience can be produced by oxygen deprivation Americanization The brain of a person who uses drugs adapts its chemistry to offset the drug effect. As drug users experience Americanization, they demonstrate signs of tolerance LSI a powerful hallucinogenic drug; also known as acid (lysergic acid thalidomide). The experience of vivid geometric images and dreamlike scenes is most likely to be triggered by Sleep Spindles A burst of oscillatory brain activity visible on an EGG that occurs during stage 2 sleep.
It consists of 12-14 Hz’s waves that occur for at least 0. 5 seconds AKA sigma bands/ sigma waves May represent periods where the brain is inhibiting processing to keep the sleeper in a tranquil state Dual Processing the principle that information is often simultaneously processed on separate conscious and unconscious tracks A car driver’s ability to navigate a familiar route while carrying on an animated conversation with passengers best illustrates its importance Alpha Waves the relatively slow brain waves of a relaxed, awake state Delta waves the large, slow brain waves associate with deep sleep (Stage 3 and 4).
Barbiturates drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and Judgment. Cortical A stress hormone that stimulates the body to make fat Night terrors sleep disorder is most likely to be accompanied by sleepwalking and sleepwalking?
The neural activation theory The neural activation theory provides a physiological explanation for dreaming Cocaine psychoactive drugs produces the quickest and most powerful rush of euphoria? Biophysically it is the interaction between one’s genetic makeup (I. E. , biology), mental health and personality (I. E. , psychology), and coloratura environment (I. E. , social) that contribute to health or illness.
