Study Guide 4 - States Of Consciousness Flashcards
1
Q
Conscious
A
- awareness of yourself and surroundings
- selective and unique and changing
- made of mental processes, thoughts, feelings
2
Q
Preconscious
A
- part of your non-conscious
- memories/stored knowledge
3
Q
Unconscious
A
- part of non-conscious
- mental activities that are involuntarily kept OUT of our conscious mind
- ex) sexual/aggressive, Freudian iceberg metaphor - potentially dangerous, disorders
- can act as protect or barrier to growth
4
Q
Non-conscious
A
-mental processes that you are NOT aware of
5
Q
Circadian Rhythm
A
- sleep and wake cycle (biological rhythm) that’s controlled by the SCN
- ex) peak degree of sleepiness at 3 am&pm
6
Q
Jet Lag
A
- sleep pattern difficulties, conflict btwn internal clock and new time zone
- easier to stay up late than go to bed earlier
7
Q
Shift Work
A
- work schedules conflicts with body’s natural circadian rhythm, difficulty adjusting
- disorder identified by pattern of sleep interruption -> insomnia, and sleepiness
8
Q
SAD
A
- depressed during fall and winter
- decreased energy
- treated with light therapy, or medication
9
Q
Non-24
A
- occurs in people who are totally blind
- for ppl with sight enviro. light cues signal the brain to reset the body’s clock to 24 hours
- for blind ppl everyday their body’s natural clock falls a little more behind until their body operates like night is day and vice versa
10
Q
SCN
A
- neurons in hypothalamus that govern timing of circadian rhythms
- controls production of melatonin
11
Q
Melatonin
A
- hormone released by the pineal gland
- sleep!
- bright light decreases its production
- teens secrete later in the evening
12
Q
Restorative Sleep Theory
A
- we sleep in order to replenish essential bodily processes
- sleep essential to normal functioning
13
Q
Evolutionary Sleep Therapy (Adaptive Non responding Theory)
A
- Sleep has developed evolutionarily (safest for us to sleep at night when vision is bad)
- each generation sleeps less
14
Q
Memory Restoration Theory
A
- R.E.M. sleep is time for the brain to organize and consolidate memories
- neural connections made and brain gets rid of unnecessary information
15
Q
Stage 1
A
- brief transition when first falling asleep
- alpha (awake and drowsy) and theta waves = low amp high frequency
16
Q
Stage 2
A
- fully asleep but brief bursts of rapid brain activity (Sleep Spindles-lots of waves very close together & K-complexes-1 very high wave)
- theta and beginning of delta waves
17
Q
Stage 3
A
- deepest sleep
- heart rate, breathing, and muscle tension all decrease
- delta waves: low freq. high amp. slow
- normally dreamless
18
Q
Stage 4
A
- VERY deep sleep
- mostly delta waves
- heart rate, breathing and muscle tension decrease
- normally dreamless
