  1. Circadian Rhythm
    The biological clock; regular body rhythms that occur on a 24-hour cycle
  2. REM Sleep
    Rapid eye movement sleep; a recurring sleep stage that during which vivid dreams commonly occur
  3. Who found out about REM Sleep?
    Eugene on his 8 year old son Armond Aserinsky with an EEG.
  4. What else is REM sleep known as and why?
    Paradoxical Sleep because the muscles are relaxed (except for minor twitches) but other body systems are active.
  5. Alpha Waves
    Relatively slow brain waves of a relaxed, awake state.
  6. Sleep
    Periodic, natural loss of consciousness
  7. Describe William Dement's experiment
    • Dement made a sleep deprived young man lie down with his eyelids taped back.
    • He told him to press a button everytime a strobe light flashed in his eyes.¬†
    • After a few minutes the man missed one and said it was because there was no flash.
    • There was a flash, he had just missed it because he fell asleep for 2 seconds.
  8. Hallucinations
    • False sensory experiences
    • Such as seeing something in the absence of an external visual stimulus
  9. Delta Waves
    Large, slow brain waves associated with deep sleep
  10. NREM Sleep
    • Non-rapid eye movement sleep
    • Encompasses all sleep stages except for REM sleep
  11. SCN
    • Suprachiasmatic Nucelus
    • Pair of cell clusters in the hypothalamus that controls circadian rhythm
    • Light intensity causes the SCN to cause the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness
  12. In what stage of sleep are likely to experience hypnagogic sensations of falling?
  13. Insomnia
    • Persistent problems in falling or stay asleep
    • Is not a disorder, it is a symptom for a deeper underlying disorder
  14. Narcolepsy
    • Sleep disorder with uncontrollable sleep attacks
    • The sufferer may lapse directly into REM sleep
  15. Sleep Apnea
    Sleep disorder with unaware temporary cessations of breathing during sleep and repeated momentary awakenings
  16. Night Terrors
    • Sleep disorder with high arousal and an appearance of being terrified
    • They are seldom remembered
    • Targets mostly children
  17. How are Night Terrors different from Nightmares?
    They occur during NREM-3 sleep, within two or 3 hours of falling asleep and are seldom remembered
  18. Dream
    Sequence of images, emotions, and thoughts passing through a sleeping person's mind
  19. Why do we dream?
    • To satisfy our own wishes
    • To file away memories
    • To develop and preserve neural pathways
    • To make sense of neural static
    • To reflect cognitive development
  20. Why do we need sleep and what kind of psychologist would say this?
    • To protect us-Evolutionist
    • To help us recuperate-Biological
    • To help us restore and rebuild our fading memories of the day's experiences-Cognitive
    • To feed our creative thinking-Cognitive
    • To support our growth-Biological
  21. Manifest Content
    Remembered storyline of our dreams according to Freud
  22. Latent Content
    The underlying meaning of a dream according to Freud
  23. REM Rebound
    The tendency for REM sleep to increase following REM sleep deprivation
  24. Consciousness
    Awareness we have about ourselves and within our enviroment
  25. Being able to process only one conscious thought at a time
    Selective Attention
  26. Why is daydreaming good?
    • It is healthy and necessary
    • We are filing away new memories
  27. Most vital portion of sleep
    REM sleep
  28. When light activates the Penial gland after you just woke up from dreaming what happens?
    You won't remember your dream
  29. The 5 Stages of sleep is also known as...
    The 90 minute cycle
  30. Seasonal depression
    Seasonal Affective Disorder
  31. What is the treatment for Seasonal Affective Disorder?
    Phototherapy or light therapy
  32. What does the 25th hour have to do with?
    Unnatural lighting
  33. What makes us finally sleep?
    • Light Intensity
    • Pineal Gland
    • Melatonin
  34. How does Light Intensity affect us?
    • Light intensity causes us to either increase or decrease melatonin production.
    • If it's dark outside melatonin is increased.
    • If it's bright outside melatonin is decreased.
  35. Why do we fall asleep gradually?
    Because Melatonin passes through the bloodstream
  36. Stage 1
    • Alpha Waves
    • Slowing of breathing
    • Increased brain activity
    • Lasts about 10 minutes
    • Very relaxed state
    • Minor Hallucinations
  37. Stage 2
    • Beta Waves
    • Sleep Spindles-twitches
    • Last about 10-15 minutes
  38. Stage 3
    • Some say it does not exist because it's so short
    • Less than 5 minutes
  39. Stage 4
    • Delta Waves
    • Deep sleep
    • Can occur with eyes open
    • Longest stage (lasts about 30-35 minutes)
  40. What type of things can happen during Stage 4?
    • Sleepwalking
    • Bedwetting
    • Night Terrors
  41. Adult Bed Wetting

  43. How to cure Insomnia
    • Exercise
    • Eat healthy
    • Try to go to bed on the same schedule regularly
  44. Theory of Narcolepsy?
    It is linked to the lack of the neurotransmitter called Hypocretin.
  45. Sleep Apnea treatments?
    • Oxygen Mask
    • Removal of Tonsils and Uvula
    • Weight loss
  46. Night Terror treatments?
    None, the child will grow out of it
  47. What is the problem with Freudian Dream Theory?
    • He interpreted everyone's dreams differently¬†
    • Very unscientific/too vague
    • Too much introspection
  48. Wish-fulfillment
    Dreams provide a psychic safety valve to discharge unacceptable feelings
  49. Information-processing
    Dreams help us sort out the day's events and consolidate our memories
  50. Physiological Function
    Regular brain stimulation from REM sleep may help develop and preserve neural pathways
  51. Neural Activation
    REM sleep triggers neural activity that evokes random visual memories which our sleeping brain weaves into stories
  52. Cognitive Development
    Dream content reflects dreamers' cognitive development - their knowledge and understanding
