  1. What is Psychology?
    The scientific study of behavior and mental processes
  2. Frontal lobe
    seat of personality;executive function
  3. Parietal Lobe (top)
    Skin senses
  4. Temporal Lobe (middle)
    Hearing
  5. Occupital
  6. Left Hemisphere
    • Speech;language
    • Logical;analyitical
    • Micro-detail oriented
    • Rational;even tempored
  7. Right Hemisphere
    • nonverbal;silent
    • intuitive;emotional
    • macro-sees big picture
    • creative;impulsive
    • moody
  8. techniques for studying the brain
    • EEG-electro act. in brain
    • Biofeedback
    • CT scans
    • PET
    • MRI
  9. EEG
    examines brain wave act;non invasive
  10. brain waves are called
    • alpha-relaxed but alert
    • beta-exhibited when worried or upset
    • theta-angry,startled
    • delta-brain injury (deepest sleep)
  11. Biofeedback?
    • parient learns how to monitor blood pressure and how to alter it
    • used to treat migrain headaches; move blood from cerebral cortex to hands
  12. nerve cell (neuron)
    • smallest in brain
    • largest in spinal cord
    • shares 3 parts (dendrites,axon,myelin)
  13. dendrites
    • search for stimulation (nerve impulse)
    • receptor sites; seratonin
  14. synaptic knob
    microscopic fluid filled gap between neuron is synapse
  15. myelin sheath
    • while fatty cholesterol builds myelin;
    • new borns arent fully myelinated
    • disappearing myelin-develop MS & could be caused by insufficient¬†vitamin D
  16. Axon
  17. Soma
  18. Central Nervous System
    • brain
    • spinal cord
    • afferent-up to brain
    • efferent nerves- move away from brain
  19. Peripheral NS
    • somatic- controls voluntary muscles responsible for body movement
    • autonomatic- sympathetic/parasympathetic
  20. sympathetic (in peripheral ns)
    • activates when bod is in stress
    • pupils dialate; fight or flight
    • body stops digestion and breathing
  21. parasympathetic (in peripheral ns)
    slows down organs back to baseline; calms body
  22. VISION
    • light is energy source
    • Cones.Rods. Retina
  23. Cones
    • center of retina
    • enable us to see color
  24. Rods
    • outer edge of retina (peripheral)
    • gathers light for vision
  25. Retina
    receptor cells (linging in back or eye)
  26. 3 cone pairs
    • Trichromatic -Normal
    • Dichromatic-limited;red/green
    • Achromats- sees no color
  27. Disorders of Visual acuity
    • Myopia-near (shape of eye)
    • Hyperopia-far (focus)
    • Presbyopia-aging eyes
  28. Audition (hearing)
    • pinna-outer ear
    • ear drum(tympanic membrane)
    • vestibular sense-monitors balance
  29. tactile sense- skin
    • mechanoreceptors.
    • thermoreceptors.
    • nociceptors
  30. mechanoreceptors(pressure)
    soft.rough.sharp
  31. thermoreceptors(temperature)
    hot,cold, both for very hot and cold
  32. nociceptors (pain)
    50% of pain is psychological
  33. olfaction(smells)
    • receptors imbedded in lining of nose
    • each cell has long hair attached
    • heredity/sex hormone play role in smell
    • pheromones-attraction;released in sweat and urine
  34. gustation (taste)
    • weakest sense
    • taste buds inside papallae (bumps)
