Periodic physiological flucuations
Biological rhythms
Our awareness of ourselves and our environment
Consciousness
the biological clock, regular bodily rhythms (for ex. of temp. and wakefullness) that occur on a 24-hour cycle
Circadian rhythm
non rapid eye movement, are brief, less emotional and don’t contain impressions
Non-REM sleep
Rapid eye movement sleep, a reoccurring 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 stay active
REM Sleep
the relatively slow brain waves of a relaxed, awake state
Alpha waves
Periodic, natural, reversible loss of consciousness- as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation (adapted from Dement)
Sleep
False sensory experiences, such as seeing something in the absence of an external visual stimulus
Hallucinations
the large, slow brain waves associated with deep sleep
Delta Waves
recurring problems in falling or staying asleep
Insomnia
a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times
Narcolepsy
a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
Sleep Apnea
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, and are seldom remembered
Night terrors
A sequence of images, emotions, and thoughts passing through a sleeping person’s mind. Dreams are notable for their hallucinatory imagry, discontinuties, and incongruities, and for the dreamer’s delusional acceptance of the context and later difficulties remembering it
Dream
According to Freud, the remembered story line of a dream (as distinct from its latent, or hidden, content).
Manifest content
According to Freud, the underlaying meaning of a dream (as distinct from its manifest content). Freud believed that a dream’s latent content functions as a safety valve
Latent Content
researchers believe this that dreams may help sift, sort, and fix the day’s experiences in our memory. REM sleep facilitates memory
Informational Processing
regular brain stimulation from REM sleep may help develop and preserve neural pathways,
Physiological Function
REM sleep triggers impulses that evoke random visual memoriies, which our sleeping brain weaves into stories
Activation-synthesis
dream content reflects dreamers cognitive development-their knowledge and understanding
Cognitive thoery
Dreams provide a “psychic safety valve”-expressing otherwise unacceptable feelings: contain manifest (remembered) content and a deeper layer of latent content- a hidden meaning
Freud’s Wish Fulfillment
dreams as part of brain maturation and cognitive development
Cognitive development
the tendency for REM sleep to increase following REM sleep deprivation (created by repeated awakenings during REM cycle)
REM Rebound
a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur.
Hypnosis
