    • fears
    • violent motives
    • sex 
    • etc
  6. Examples of nonconscious
    physiological activities
  7. EEG scans
    brain wave activity

    In a night's sleep, you go through four or five cycles of 90 minute sleep

    each stage has its own rhythm and corresponding changes in brain activity and behavior
  8. As you close your eyes and begin to relax, you move from __ to __
    normal wakefulness (beta waves) to drowsy relaxation (alpha waves)

    • lower HR

    • Stage one: it starts to drop
    • Stage two: it gets lower

    • we dream to fulfill our wishes; things we can't act on in real life

    Manifest: what you actuallya re dreaming

    Latent: analyzing
  22. 2) Biological view
    activation-synthesis hypothesis: dreams are neuron's meaningless byproducts
  23. 3) Cognitive View
    - fundamental process: needed for survival; mental house cleaning (brain organizing day's material)

    Problem solving theory: dreams give people a chance to review and address problems from the day; incubation period; "sleep on it"

    suddenly falling into REM sleep
  27. SIDS
    sudden infant death syndrome

    • babies need to be on back to sleep

    • can be genetic if brain tells body to stop breathing

    risky up until about four months
  28. REM behavior disorder
    acting out your dreams
  29. types of drugs
    stimulant: anything that increases NS activity (ex: caffeine, etc.)

    depressant: anything that decreases NS activity (ex: alcohol)
