AP psych - consciousness

Awareness

1. sensory
2. self
-emotions
-feelings
3. Freud stuff

Altered States

-when asleep -> less aware of self
-sleeping, dreaming, drug use, hypnosis

Why sleep?

1. it allows us to conserve energy, repair damage to the body, and store and organize information.
2. rid waste - in the brain -> if not asleep, not able to "rid waste"
-physical
-mental
3. immune system - sick; injured

How? (much)

1. Babies = 10-14 hours (maybe 20)
2. Adults = 7-9 hours
3. Sleep Debt - hard to get rid of

Circadian Rythms

1. 24 bio clock
2. jet lag
3. melatonin (hormone) - sun -> hypothalamus -> pineal gland
4. manage what time we go to bed

Sleep Stages

brain waves
1. Stage 1 - alpha waves: neural activity decreases
2. Stage 2 - sleep spindles: neural activity decreasing. Easily woken up.
3. Stage 3 & 4 - "deep sleep" - delta waves : brain is least active. Feel worse after getting 8 hrs. of sleep.
4. REM

REM

- "Paradoxical Sleep": Brain extremely active -> body is "locked down"; body doesn't move.
- Dreaming
- Rapid eye movement

Cycles

20 minute nap = coffee; 6-8 hrs. of energy; Stage 1 & 2
90 minutes = more energy (boost); Awake -> REM
Stage 3 & 4 - danger zone
1. 3/4 -> REM; REM increases the longer you sleep
2. REM Rebound - put body in REM earlier & stay in longer
3. Most in stage 2

Dreaming

Pons
1. Evolution
-threat perception
2. Biological
-long-term potentiation/info processing (memory consolidation)
-Activation Synthesis
3. Psychoanalytic (Freud)
-unconscious: work through conflicts in a safe way through dreaming
-manifest vs. latent content
4. Psychodynamic (Carl Jung)
-collective unconscious

memory consolidation

rerunning routs in brain

threat perception

fear, loneliness, embarrassment, etc.

activation synthesis

random things in dream

manifest content

story of the dream - part you remember

latent content

hidden meaning of a fantasy or dream

collective unconscious

cloud; google doc; Things are connected in a universal way. Things are the same to everybody

where does dreaming occur in the brain?

pons
