Test #3 Flashcards
Consciousness
degree of awareness
menstrual cycle, breathing, bathroom, sleep/wake
Biological circadian clocks
drowsiness, still awake, low eyes 8-12 waves per second combination on the EEG
Alpha stage
lightest stage of sleep, lasts max seven minutes, consciousness decreasing, wave frequently 4-7 waves per second on EEG
Stage 1
takes 15-20 mins to get here, falling deeper asleep, blood pressure decreasing, brain waves spike, sleep spindles
Stage 2
heart rate and temperature decrease, EEG brain wave pattern decreases. Slow rhythmic pattern
Stage 3&4
deepest sleep, rapid eye movement. Eyes moving back and forth. State that you dream in. low amplitude wave thats high in frequency 14-25 waves per second
REM sleep
your unconscious freely expresses itself even while your body is at rest. Interpretation of every dream had to have a sexual content (not true) Freud
Freud idea of conscious and unconscious
Dreams reflect waking concerns, when you’re sleeping your brain works on the same things it does when it’s awake. Relation to what is going on in wake life to dream. Most evidence of this Rosalind Cartwright
Extensions of waking life theory-Rosalind Cartwright
Dreams are entirely rem, nothing meaningful to why we activate certain memories. Help us better remember. Piece together meaning to memories that are typically random.J Allan Hobson
Activation Synthesis theory- J Allan Hobson
dream of threatening things to be prepared for said threat
Threat simulation theory
what is typical content for dreams?
normally involve people, will take place inside rather than outside. Can only dream of things already in your memory.
what type of emotions do dreams typically convey?
Emotions tend to be negative rather than positive. Your brain feels like it needs to resolve an issue.
1700s Anton Mesmer, dissociated consciousness. Perception is altered.
Hypnosis
someone suggesting a smell, pain, but believing what you want.
socio-cognitive theory-
was hard for the subject to deal with so they are told not to remember and they don’t.
Posthypnotic amnesia
located in the center of the brain.
secretion increases with darkness and decreases with light. drugs do not work unless you have a deficiency.
Melatonin
occurs in older people,
voluntary muscles are paralyzed and sleepers will act out their dreams (causes them to break a hand, punch a wall, hit a spouse)
REM behavior disorder
low body temperature in the morning and it rises throughout the day, temperature of a morning person rises more quickly 1-3 hours earlier than an evening person
getting up
body temperature of a morning person peaks earlier in the evening and an evening person’s body temp peaks 1-3 hours later, so they would go to bed later.
going to bed
increased activity in the suprachiasmatic nucleus, which regulates the sleep cycle, not as susceptible to fatigue
evening people
what percent of adults sleep six hours or less per night?
16%
what percent of adults sleep 6-7 hours per night?
24%
what percent of adults sleep 8 or more hours per night?
26%
what percent of adults sleep 7-8 hours per night?
31%
how many hours of sleep does a child need
9 hours
how many hours a day does a new born sleep?
17 hours
how many hours of sleep do elderly people need?
6.5 hours a night but naps make up lost sleep
