Flashcards in chapter 3 consciousness and the two-track mind recall Deck (43):
our awareness of ourselves and our environment.
the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language).
the principle that information is often simultaneously processed on separate conscious and unconscious tracks.
a condition in which a person can respond to a visual stimulus without consciously experiencing it.
the focusing of conscious awareness on particular stimulus.
failing to see visible objects when our attention is directed elsewhere
failing to notice changes in the environment.
the biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle.
rapid 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.
the relatively slow brain waves of a relaxed, awake state.
periodic, natural, reversible loss of consciousness-as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation.
false sensory experiences, such as seeing something in the absence of an external visual stimulus.
the large, slow brain waves associated with deep sleep.
recurring problems in falling or staying asleep.
a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times.
a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings.
a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terror occur during NREM-3 sleep, within two or three hours of falling asleep, and are seldom remembered.
a sequence of images, emotions, and thoughts passing through a sleeping person's mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer's delusional acceptance of the content and later difficulties remembering it.
according to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content).
according to Freud, the underlying meaning of a dream (as distinct from its manifest content).
the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM sleep).
a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur.
a suggestion, made during a hypnosis session, to be carried out after the subject is no longer hypnotized; used by some clinicians to help control undesired symptoms and behaviors.
a split in consciousness, which allows some thoughts and behaviors to occur simultaneously with others.
a chemical substance that alters perceptions and moods.
the diminishing effect with regular use of the some dose of a drug, requiring the user to take larger and larger does before experiencing the drug's effect.
compulsive drug craving and use, despite adverse consequences.
the discomfort and distress that follow discontinuing the use of an addictive drug.
a physiological need for a drug, marked by unpleasant withdrawal symptoms when the drug is discontinued.
a psychological need to use a drug, such as to relieve negative emotions.
drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions.
(popularly known as alcoholism). Alcohol use marked by tolerance, withdrawal if suspended, and a drive to continue use.
drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgment.
opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessoning pain and anxiety.
drugs (such as caffeine, nicotine, and the more powerful amphetamines, cocaine, ecstasy, and methamphetamine) that excite neural activity and speed up body functions.
drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes.
a stimulating and highly addictive psychoactive drug in tobacco.
a powerfully addictive drug that stimulates the central nervous system, with speeded-up body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels.
a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and longer-term harm to serotonin-producing neurons and to mood and cognition.
psychedelic (“mind-manifesting”) drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input.
a powerful hallucinogenic drug; also known as acid (lysergic acid diethylamide).
an altered sate of consciousness reported after a close brush with death (such as through cardiac arrest); often similar to drug-induced hallucinations.
