    • Pinna: Outer ear or "sound collector
    • Eardrum: vibrates in response to sound waves
    • Ossicles: middle earbones convert vibrations into smaller motions
    • Cochlea: houses inner ear's neural tissue
  2. What is Auditory Localization?
    it helps us to have timing and to place our location where ever we are
  3. Tactile System
    pressure, temperature, and pain

    when pain occurs the brain uses endorphines to suppress

  6. Gestalt Psychology
    integrate informational pieces in organised whole
  7. Form Perception
    • Figure/Ground: seperate figure (object of interest) from the ground (objects not of interest)
    • Grouping: organize stimuli into coherent groups
  8. Depth Perception
    eye senses 2D --> brain makes #D (allows us to determine depth)
  9. Depth Cues
    • Monocular: available to one eye
    • Binocular: dependent on both eyes
  10. Retinal Disparity
    Compares difference between 2 eyes
  11. Relative Height
    Objects higher in field of vision appear farther away
  12. Reletive Size
    assumed objects are of the same size, smaller objects in the field of view are farther away
  13. Interpositions
    if an objects blocks another, the one block is in front of the other
  14. Liniar Perspective
    the more assumes parallel lines converge, the farther away it gets
  15. Light and Shadow
    objects that reflect more light are closer then those farther away
  16. Perceptual Set
    metal predisposition to see one thing and not another
  17. Context Effects
    enviromental effect perception (teacher at class vs. teacher at the store)
  18. Conciousness
    Awareness and enviroment
  19. Selective Attention
    Focusing on particular stimulus
  20. Unattentional Blindness
    failing to see objects because attentino is directed elsewhere
  21. Circadian Rythms
    biological 24-hour clock (regulates alertness and temperature)
  22. Owls vs. Larks
    • Owls: awake at night
    • Larks: awake in the day
  23. Microsleep
    your brain makes you fall asleep whatever you are doing if the need is dire
  24. Sleep Stages
    • Beta: alert wakefulness
    • Alpha: Relaxed awake state
    • Stage 1: Theta waves, hallucinations and hypnagogic experiences common, easily awakened
    • Stage 2: Sleep Spindles (rapid brain waves), sleep talking common


    • Stages 3&4: Deep Sleep, delta waves, hard to awaken
    • REM: Rapid Eye Movement; vivid dreams, relaxed muscles (resemble Alpha waves)
  25. Benifits of Adequate Sleep
    improved mood, more efficient, improves memory, strengthens immune system, lessens risks of fatal accidents, reduces premature aging, lessens risk for obesity and hypertention
  26. Insomnia
    Persistant trouble falling asleep, difficult to remain asleep, wake early in the morning
  27. Narcolepsy

  43. Hallucinogens
    sensory distortion and mental/emotional effects
  44. MDMA
    related to amphetamines and hallucinogens
