Chapter 7 Apes Flashcards
Consciousness
our awareness of ourselves and our environments
Biological rhythm
periodic psychological fluctuation
Circadian rhythm
the biological clock; regular bodily rhythms (temperature + wakefulness) that occur on a 24 hour cycle.
R.E.M. Sleep
rapid eye movement sleep, a recurring sleep stage during which vivid dreams commonly occur. AKA paradoxical sleep, because the muscles are relaxed (except minor twitches) but other body systems are active.
Alpha waves
the relatively slow brain waves of a relaxed, awake state.
Sleep
periodic, natural, reversible loss of consciousness– as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation.
Hallucinations
false sensory experiences, such as seeing something in the absence of an external visual stimulus.
Delta waves
the large, slow brain waves associated with deep sleep
Insomnia
recurring problems in falling or staying asleep
Narcolepsy
a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times.
Sleep apnea
a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings
Night terrors
a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, this occurs during stage 4 sleep, within 2-3 hours of falling sleep, and are seldom remembered.
Dreams
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 content and later difficulties remembering it.
Freud’s wish fulfillment
Dreams provide a “psychic safety valve” – expressing otherwise unacceptable feelings; contain manifest (remembered) content and a deeper layer of latent content– a hidden meaning.
Manifest content
according to Frued, the remembering story line of a dream (as distinct form its latent, or hidden, content.
Patent content
according to Frued, the underlying meaning of a dream (as distinct from its manifest content). Frued believed that a dream’s this functions as a safety valve.
Information processing
Dreams help us sort out the day’s events and consolidate our memories
Physiological function
regular brain stimulation from REM sleep may help develop and preserve neural pathways.
Activation synthesis
REM sleep triggers neural activity that evokes random visual memories, which our sleeping brains weave into stories.
