Flashcards in Unit 5 Deck (54):
our awareness of ourselves and our environments
the biological clock; regular bodily rhythms that occur on a 24 hour cycle
rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. The muscles are relaxed, but other body systems are active
the relatively slow brain waves of a relaxed, awake state
periodic, natural loss of consciousness
false sensory experiences, such as something in the absence of an external visual stimuli
the large, slow brain waves associated with deep sleep
non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep.
recurring problems in falling or staying asleep
a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may laps directly into REM sleep, often at inopportune moments.
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 terrors occur during Stage 4 sleep, within two or three hours of falling asleep. they are seldom remembered.
a sequence of images, emotions, and thoughts passing through a sleeping persons mind. They are usually hallucinatory.
according to Freud, the remembered story line of a dream
according to Freud, the underlying meaning of a dream
the tendency for REM sleep to increase following REM sleep deprivation (waking people up during REM)
a social interaction in which a hypnotist suggests to a subject that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur
post hypnotic suggestion
a suggestion made during hypnosis session, to be carried out after the subject is no longer hypnotized.
a split, in consciousness, which allows some thoughts and behavior to occur simultaneously with others
psycho active drug
a chemical substance that alters perceptions and moods
the diminishing effect with regular use of the same dose of a drug
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
compulsive drug craving and use, despite adverse consequences
drugs (such as alcohol) that reduce neural activity and slow body functions
drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgement
opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety
drugs (such as caffeine, and nicotine) that excite neural activity.
drugs that stimulate neural activity, causing speeded up body functions and associated energy and mood changes
stimulates the central nervous system, speeds up body functions, associated energy and mood changes
a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy.
psychedelic drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input.
A POWERFUL HALLUCINOGENIC DRUG; ALSO ACID
an altered state of consciousness reported after a close brush with death. Also caused by hallucinogens.
the major addictive ingredient in marijuana; triggers a variety of effects, including mild hallucinogens

Activation Synthesis Theory
Dreams organize the inevitable random neural activity during sleep
Cognitive Development Dream Theory
we dream for brain maturation and cognitive development
Freud's Wish-fulfillment Dream Theory
Dreams allow us to express otherwise unacceptable fantasies
Information-Processing Dream Theory
