Dreams
Random
100
Dream content reflects dreamers' cognitive development, their knowledge and understanding.
What is Cognitive Theory
100
A sleep disorder characterized by high arousal and an appearance of being terrified.
What is Night Terrors
100
is light sleep where you drift in and out of sleep and can be awakened easily. In this stage, the eyes move slowly and muscle activity slows. During this stage, many people experience sudden muscle contractions preceded by a sensation of falling.
What is Stage 1
100
A sequence of images, emotions, and thoughts passong through a sleeping person's mind.
What is Dreams
100
the biological clock; regular bodily rhythms
What is circadian rhythm
200
Dreams provide a "psychic safety valve"- expressing otherwise unacceptable feelings; contain manifest(remembered) content adn a deeper layer of latent content- a hidden meaning.
What is Freud's Wish-Fulfillment Theory
200
Recurring problems in falling or staying asleep.
What is Insomnia
200
extremely slow brain waves called delta waves are interspersed with smaller, faster waves
What is Stage 3
200
Is the remembered story line of a dream.
What is Manifest Content
200
the relatively slow brain waves of a relaxed, awake state.
What is Alpha waves
300
Dreams help us sort out the day's events adn consolidate our memories.
What is informational-processing Theory
300
A sleep disorder characterized by uncontrollable sleep attacks.
What is Narcolepsy
300
the brain produces delta waves almost exclusively. Stages 3 and 4 are referred to as deep sleep, and it is very difficult to wake someone from them. In deep sleep, there is no eye movement or muscle activity. This is when some children experience bedwetting, sleepwalking or night terrors
What is Stage 4
300
Is the underlying meaning of a dream.
What is Latent Content
300
the large, slow brain waves associated with deep sleep.
What is delta waves
400
Regular brain stimulation from REM sleep may help develop and preserve neural pathways.
What is Physiological function
400
A sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings.
What is Sleep apnea
400
eye movement stops and brain waves become slower with only an occasional burst of rapid brain waves
What is Stage 2
400
vivid, emotional, and bizarre. Unlike daydreams, often condused with reality.
What is REM Dreams
400
false sensory experiences, such as seeing something in the absence of an external visual stimulus.
What is hallucinations
500
REM sleep triggers neural activity that evokes random visual memories, which our sleeping brain weaves into stories.
What is Activation-synthesis Theory
500
Sleep disorder that leaves 10 to 15 percent of adults complaining.
What is Insomnia
500
breathing becomes more rapid, irregular and shallow, eyes jerk rapidly and limb muscles are temporarily paralyzed. Brain waves during this stage increase to levels experienced when a person is awake
What is REM Sleep
500
the tendency for REM sleep to increase following REM sleep deprivation.
What is REM rebound
500
periodic, natural, reversible loss of conciousness
What is sleep
